Contributing to LangChain | 🦜️🔗 Langchain,https://python.langchain.com/docs/contributing,langchain_docs,"Main:  On this page #Contributing to LangChain Hi there! Thank you for even being interested in contributing to LangChain. As an open-source project in a rapidly developing field, we are extremely open to contributions, whether they involve new features, improved infrastructure, better documentation, or bug fixes.  ##🗺️ Guidelines[​](#️-guidelines) ###👩‍💻 Contributing Code[​](#-contributing-code) To contribute to this project, please follow the [""fork and pull request""](https://docs.github.com/en/get-started/quickstart/contributing-to-projects) workflow. Please do not try to push directly to this repo unless you are a maintainer.  Please follow the checked-in pull request template when opening pull requests. Note related issues and tag relevant maintainers.  Pull requests cannot land without passing the formatting, linting, and testing checks first. See [Testing](#testing) and [Formatting and Linting](#formatting-and-linting) for how to run these checks locally.  It's essential that we maintain great documentation and testing. If you:  - Fix a bug - Add a relevant unit or integration test when possible. These live in tests/unit_tests and tests/integration_tests. - Make an improvement - Update any affected example notebooks and documentation. These live in docs. - Update unit and integration tests when relevant. - Add a feature - Add a demo notebook in docs/docs/. - Add unit and integration tests. We are a small, progress-oriented team. If there's something you'd like to add or change, opening a pull request is the best way to get our attention.  ###🚩GitHub Issues[​](#github-issues) Our [issues](https://github.com/langchain-ai/langchain/issues) page is kept up to date with bugs, improvements, and feature requests.  There is a taxonomy of labels to help with sorting and discovery of issues of interest. Please use these to help organize issues.  If you start working on an issue, please assign it to yourself.  If you are adding an issue, please try to keep it focused on a single, modular bug/improvement/feature. If two issues are related, or blocking, please link them rather than combining them.  We will try to keep these issues as up-to-date as possible, though with the rapid rate of development in this field some may get out of date. If you notice this happening, please let us know.  ###🙋Getting Help[​](#getting-help) Our goal is to have the simplest developer setup possible. Should you experience any difficulty getting setup, please contact a maintainer! Not only do we want to help get you unblocked, but we also want to make sure that the process is smooth for future contributors.  In a similar vein, we do enforce certain linting, formatting, and documentation standards in the codebase. If you are finding these difficult (or even just annoying) to work with, feel free to contact a maintainer for help - we do not want these to get in the way of getting good code into the codebase.  ##🚀 Quick Start[​](#-quick-start) This quick start guide explains how to run the repository locally. For a [development container](https://containers.dev/), see the [.devcontainer folder](https://github.com/langchain-ai/langchain/tree/master/.devcontainer).  ###Dependency Management: Poetry and other env/dependency managers[​](#dependency-management-poetry-and-other-envdependency-managers) This project utilizes [Poetry](https://python-poetry.org/) v1.6.1+ as a dependency manager.  ❗Note: Before installing Poetry, if you use Conda, create and activate a new Conda env (e.g. conda create -n langchain python=3.9)  Install Poetry: [documentation on how to install it](https://python-poetry.org/docs/#installation).  ❗Note: If you use Conda or Pyenv as your environment/package manager, after installing Poetry, tell Poetry to use the virtualenv python environment (poetry config virtualenvs.prefer-active-python true)  ###Core vs. Experimental[​](#core-vs-experimental) This repository contains two separate projects:  - langchain: core langchain code, abstractions, and use cases. - langchain.experimental: see the [Experimental README](https://github.com/langchain-ai/langchain/tree/master/libs/experimental/README.md) for more information. Each of these has its own development environment. Docs are run from the top-level makefile, but development is split across separate test & release flows.  For this quickstart, start with langchain core:  cd libs/langchain  ###Local Development Dependencies[​](#local-development-dependencies) Install langchain development requirements (for running langchain, running examples, linting, formatting, tests, and coverage):  poetry install --with test  Then verify dependency installation:  make test  If the tests don't pass, you may need to pip install additional dependencies, such as numexpr and openapi_schema_pydantic.  If during installation you receive a WheelFileValidationError for debugpy, please make sure you are running Poetry v1.6.1+. This bug was present in older versions of Poetry (e.g. 1.4.1) and has been resolved in newer releases. If you are still seeing this bug on v1.6.1, you may also try disabling ""modern installation"" (poetry config installer.modern-installation false) and re-installing requirements. See [this debugpy issue](https://github.com/microsoft/debugpy/issues/1246) for more details.  ###Testing[​](#testing) some test dependencies are optional; see section about optional dependencies.  Unit tests cover modular logic that does not require calls to outside APIs. If you add new logic, please add a unit test.  To run unit tests:  make test  To run unit tests in Docker:  make docker_tests  There are also [integration tests and code-coverage](https://github.com/langchain-ai/langchain/tree/master/libs/langchain/tests/README.md) available.  ###Formatting and Linting[​](#formatting-and-linting) Run these locally before submitting a PR; the CI system will check also.  ####Code Formatting[​](#code-formatting) Formatting for this project is done via [ruff](https://docs.astral.sh/ru"
Contributing to LangChain | 🦜️🔗 Langchain,https://python.langchain.com/docs/contributing,langchain_docs,"ff/rules/).  To run formatting for docs, cookbook and templates:  make format  To run formatting for a library, run the same command from the relevant library directory:  cd libs/{LIBRARY} make format  Additionally, you can run the formatter only on the files that have been modified in your current branch as compared to the master branch using the format_diff command:  make format_diff  This is especially useful when you have made changes to a subset of the project and want to ensure your changes are properly formatted without affecting the rest of the codebase.  ####Linting[​](#linting) Linting for this project is done via a combination of [ruff](https://docs.astral.sh/ruff/rules/) and [mypy](http://mypy-lang.org/).  To run linting for docs, cookbook and templates:  make lint  To run linting for a library, run the same command from the relevant library directory:  cd libs/{LIBRARY} make lint  In addition, you can run the linter only on the files that have been modified in your current branch as compared to the master branch using the lint_diff command:  make lint_diff  This can be very helpful when you've made changes to only certain parts of the project and want to ensure your changes meet the linting standards without having to check the entire codebase.  We recognize linting can be annoying - if you do not want to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.  ####Spellcheck[​](#spellcheck) Spellchecking for this project is done via [codespell](https://github.com/codespell-project/codespell). Note that codespell finds common typos, so it could have false-positive (correctly spelled but rarely used) and false-negatives (not finding misspelled) words.  To check spelling for this project:  make spell_check  To fix spelling in place:  make spell_fix  If codespell is incorrectly flagging a word, you can skip spellcheck for that word by adding it to the codespell config in the pyproject.toml file.  [tool.codespell] ... # Add here: ignore-words-list = 'momento,collison,ned,foor,reworkd,parth,whats,aapply,mysogyny,unsecure'  ##Working with Optional Dependencies[​](#working-with-optional-dependencies) Langchain relies heavily on optional dependencies to keep the Langchain package lightweight.  You only need to add a new dependency if a unit test relies on the package. If your package is only required for integration tests, then you can skip these steps and leave all pyproject.toml and poetry.lock files alone.  If you're adding a new dependency to Langchain, assume that it will be an optional dependency, and that most users won't have it installed.  Users who do not have the dependency installed should be able to import your code without any side effects (no warnings, no errors, no exceptions).  To introduce the dependency to the pyproject.toml file correctly, please do the following:  - Add the dependency to the main group as an optional dependency poetry add --optional [package_name]  - Open pyproject.toml and add the dependency to the extended_testing extra - Relock the poetry file to update the extra. poetry lock --no-update  - Add a unit test that the very least attempts to import the new code. Ideally, the unit test makes use of lightweight fixtures to test the logic of the code. - Please use the @pytest.mark.requires(package_name) decorator for any tests that require the dependency. ##Adding a Jupyter Notebook[​](#adding-a-jupyter-notebook) If you are adding a Jupyter Notebook example, you'll want to install the optional dev dependencies.  To install dev dependencies:  poetry install --with dev  Launch a notebook:  poetry run jupyter notebook  When you run poetry install, the langchain package is installed as editable in the virtualenv, so your new logic can be imported into the notebook.  ##Documentation[​](#documentation) While the code is split between langchain and langchain.experimental, the documentation is one holistic thing. This covers how to get started contributing to documentation.  From the top-level of this repo, install documentation dependencies:  poetry install  ###Contribute Documentation[​](#contribute-documentation) The docs directory contains Documentation and API Reference.  Documentation is built using [Docusaurus 2](https://docusaurus.io/).  API Reference are largely autogenerated by [sphinx](https://www.sphinx-doc.org/en/master/) from the code. For that reason, we ask that you add good documentation to all classes and methods.  Similar to linting, we recognize documentation can be annoying. If you do not want to do it, please contact a project maintainer, and they can help you with it.

LangChain Expression Language (LCEL) | 🦜️🔗 Langchain,https://python.langchain.com/docs/expression_language/,langchain_docs,"Main:  #LangChain Expression Language (LCEL) LangChain Expression Language, or LCEL, is a declarative way to easily compose chains together. LCEL was designed from day 1 to support putting prototypes in production, with no code changes, from the simplest “prompt + LLM” chain to the most complex chains (we’ve seen folks successfully run LCEL chains with 100s of steps in production). To highlight a few of the reasons you might want to use LCEL:  Streaming support When you build your chains with LCEL you get the best possible time-to-first-token (time elapsed until the first chunk of output comes out). For some chains this means eg. we stream tokens straight from an LLM to a streaming output parser, and you get back parsed, incremental chunks of output at the same rate as the LLM provider outputs the raw tokens.  Async support Any chain built with LCEL can be called both with the synchronous API (eg. in your Jupyter notebook while prototyping) as well as with the asynchronous API (eg. in a [LangServe](/docs/langsmith) server). This enables using the same code for prototypes and in production, with great performance, and the ability to handle many concurrent requests in the same server.  Optimized parallel execution Whenever your LCEL chains have steps that can be executed in parallel (eg if you fetch documents from multiple retrievers) we automatically do it, both in the sync and the async interfaces, for the smallest possible latency.  Retries and fallbacks Configure retries and fallbacks for any part of your LCEL chain. This is a great way to make your chains more reliable at scale. We’re currently working on adding streaming support for retries/fallbacks, so you can get the added reliability without any latency cost.  Access intermediate results For more complex chains it’s often very useful to access the results of intermediate steps even before the final output is produced. This can be used to let end-users know something is happening, or even just to debug your chain. You can stream intermediate results, and it’s available on every [LangServe](/docs/langserve) server.  Input and output schemas Input and output schemas give every LCEL chain Pydantic and JSONSchema schemas inferred from the structure of your chain. This can be used for validation of inputs and outputs, and is an integral part of LangServe.  Seamless LangSmith tracing integration As your chains get more and more complex, it becomes increasingly important to understand what exactly is happening at every step. With LCEL, all steps are automatically logged to [LangSmith](/docs/langsmith/) for maximum observability and debuggability.  Seamless LangServe deployment integration Any chain created with LCEL can be easily deployed using [LangServe](/docs/langserve).  "

It is formed when a massive star collapses under its own gravity during a supernova explosion. The collapse causes an incredibly dense mass to be concentrated in a small volume, creating a gravitational field that is so intense that it warps space and time. Black holes have a boundary called the event horizon, which marks the point of no return for anything that gets too close. Beyond the event horizon, the gravitational pull is so strong that even light cannot escape, hence the name ""black hole."" While we have a good understanding of black holes, there is still much to learn, especially about what happens inside them.  print(chain.invoke(""What's a path integral""))      Using MATH     Thank you for your kind words! I will do my best to break down the concept of a path integral for you.          In mathematics and physics, a path integral is a mathematical tool used to calculate the probability amplitude or wave function of a particle or system of particles. It was introduced by Richard Feynman and is an integral over all possible paths that a particle can take to go from an initial state to a final state.          To understand the concept better, let's consider an example. Suppose we have a particle moving from point A to point B in space. Classically, we would describe this particle's motion using a definite trajectory, but in quantum mechanics, particles can simultaneously take multiple paths from A to B.          The path integral formalism considers all possible paths that the particle could take and assigns a probability amplitude to each path. These probability amplitudes are then added up, taking into account the interference effects between different paths.          To calculate a path integral, we need to define an action, which is a mathematical function that describes the behavior of the system. The action is usually expressed in terms of the particle's position, velocity, and time.          Once we have the action, we can write down the path integral as an integral over all possible paths. Each path is weighted by a factor determined by the action and the principle of least action, which states that a particle takes a path that minimizes the action.          Mathematically, the path integral is expressed as:          ∫ e^(iS/ħ) D[x(t)]          Here, S is the action, ħ is the reduced Planck's constant, and D[x(t)] represents the integration over all possible paths x(t) of the particle.          By evaluating this integral, we can obtain the probability amplitude for the particle to go from the initial state to the final state. The absolute square of this amplitude gives us the probability of finding the particle in a particular state.          Path integrals have proven to be a powerful tool in various areas of physics, including quantum mechanics, quantum field theory, and statistical mechanics. They allow us to study complex systems and calculate probabilities that are difficult to obtain using other methods.          I hope this explanation helps you understand the concept of a path integral. If you have any further questions, feel free to ask!    "

The cons mentioned above can be mitigated or overcome with proper training, support, and a commitment to continuous improvement. It is also important to note that not all cons may be applicable to every organization or project.\n\nFor example, while Scrum may be complex initially, with proper training and guidance, teams can quickly grasp the concepts and practices. The lack of predictability can be mitigated by implementing techniques such as velocity tracking and release planning. The limited documentation can be addressed by maintaining a balance between lightweight documentation and clear communication among team members. The dependency on team collaboration can be improved through effective communication channels and regular team-building activities.\n\nScrum can be scaled and adapted to larger projects by using frameworks like Scrum of Scrums or LeSS (Large Scale Scrum). Concerns about speed versus quality can be addressed by incorporating quality assurance practices, such as continuous integration and automated testing, into the Scrum process. Scope creep can be managed by having a well-defined and prioritized product backlog, and a strong product owner can be developed through training and mentorship.\n\nResistance to change can be overcome by providing proper education and communication to stakeholders and involving them in the decision-making process. Ultimately, the cons of Scrum can be seen as opportunities for growth and improvement, and with the right mindset and support, they can be effectively managed.\n\nIn conclusion, while Scrum may have its challenges and potential cons, the benefits and advantages it offers in terms of collaboration, flexibility, adaptability, transparency, and customer satisfaction make it a widely adopted and successful project management framework.

Invoking: `Wikipedia` with `List of presidents of the United States`               Page: List of presidents of the United States     Summary: The president of the United States is the head of state and head of government of the United States, indirectly elected to a four-year term via the Electoral College. The officeholder leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. Since the office was established in 1789, 45 men have served in 46 presidencies. The first president, George Washington, won a unanimous vote of the Electoral College. Grover Cleveland served two non-consecutive terms and is therefore counted as the 22nd and 24th president of the United States, giving rise to the discrepancy between the number of presidencies and the number of persons who have served as president. The incumbent president is Joe Biden.The presidency of William Henry Harrison, who died 31 days after taking office in 1841, was the shortest in American history. Franklin D. Roosevelt served the longest, over twelve years, before dying early in his fourth term in 1945. He is the only U.S. president to have served more than two terms. Since the ratification of the Twenty-second Amendment to the United States Constitution in 1951, no person may be elected president more than twice, and no one who has served more than two years of a term to which someone else was elected may be elected more than once.Four presidents died in office of natural causes (William Henry Harrison, Zachary Taylor, Warren G. Harding, and Franklin D. Roosevelt), four were assassinated (Abraham Lincoln, James A. Garfield, William McKinley, and John F. Kennedy), and one resigned (Richard Nixon, facing impeachment and removal from office). John Tyler was the first vice president to assume the presidency during a presidential term, and set the precedent that a vice president who does so becomes the fully functioning president with his presidency.Throughout most of its history, American politics has been dominated by political parties. The Constitution is silent on the issue of political parties, and at the time it came into force in 1789, no organized parties existed. Soon after the 1st Congress convened, political factions began rallying around dominant Washington administration officials, such as Alexander Hamilton and Thomas Jefferson. Concerned about the capacity of political parties to destroy the fragile unity holding the nation together, Washington remained unaffiliated with any political faction or party throughout his eight-year presidency. He was, and remains, the only U.S. president never affiliated with a political party.          Page: List of presidents of the United States by age     Summary: In this list of presidents of the United States by age, the first table charts the age of each president of the United States at the time of presidential inauguration (first inauguration if elected to multiple and consecutive terms), upon leaving office, and at the time of death. Where the president is still living, their lifespan and post-presidency timespan are calculated up to November 14, 2023.          Page: List of vice presidents of the United States     Summary: There have been 49 vice presidents of the United States since the office was created in 1789. Originally, the vice president was the person who received the second-most votes for president in the Electoral College. But after the election of 1800 produced a tie between Thomas Jefferson and Aaron Burr, requiring the House of Representatives to choose between them, lawmakers acted to prevent such a situation from recurring. The Twelfth Amendment was added to the Constitution in 1804, creating the current system where electors cast a separate ballot for the vice presidency.The vi"

Nine vice presidents have ascended to the presidency in this way: eight (John Tyler, Millard Fillmore, Andrew Johnson, Chester A. Arthur, Theodore Roosevelt, Calvin Coolidge, Harry S. Truman, and Lyndon B. Johnson) through the president's death and one (Gerald Ford) through the president's resignation. The vice president also serves as the president of the Senate and may choose to cast a tie-breaking vote on decisions made by the Senate. Vice presidents have exercised this latter power to varying extents over the years.Before adoption of the Twenty-fifth Amendment in 1967, an intra-term vacancy in the office of the vice president could not be filled until the next post-election inauguration. Several such vacancies occurred: seven vice presidents died, one resigned and eight succeeded to the presidency. This amendment allowed for a vacancy to be filled through appointment by the president and confirmation by both chambers of the Congress. Since its ratification, the vice presidency has been vacant twice (both in the context of scandals surrounding the Nixon administration) and was filled both times through this process, namely in 1973 following Spiro Agnew's resignation, and again in 1974 after Gerald Ford succeeded to the presidency. The amendment also established a procedure whereby a vice president may, if the president is unable to discharge the powers and duties of the office, temporarily assume the powers and duties of the office as acting president. Three vice presidents have briefly acted as president under the 25th Amendment: George H. W. Bush on July 13, 1985; Dick Cheney on June 29, 2002, and on July 21, 2007; and Kamala Harris on November 19, 2021.     The persons who have served as vice president were born in or primarily affiliated with 27 states plus the District of Columbia. New York has produced the most of any state as eight have been born there and three others considered it their home state. Most vice presidents have been in their 50s or 60s and had political experience before assuming the office. Two vice presidents—George Clinton and John C. Calhoun—served under more than one president. Ill with tuberculosis and recovering in Cuba on Inauguration Day in 1853, William R. King, by an Act of Congress, was allowed to take the oath outside the United States. He is the only vice president to take his oath of office in a foreign country.          Page: List of presidents of the United States by net worth     Summary: The list of presidents of the United States by net worth at peak varies greatly. Debt and depreciation often means that presidents' net worth is less than $0 at the time of death. Most presidents before 1845 were extremely wealthy, especially Andrew Jackson and George Washington.         Presidents since 1929, when Herbert Hoover took office, have generally been wealthier than presidents of the late nineteenth and early twentieth centuries; with the exception of Harry S. Truman, all presidents since this time have been millionaires. These presidents have often received income from autobiographies and other writing. Except for Franklin D. Roosevelt and John F. Kennedy (both of whom died while in office), all presidents beginning with Calvin Coolidge have written autobiographies. In addition, many presidents—including Bill Clinton—have earned considerable income from public speaking after leaving office.The richest president in history may be Donald Trump. However, his net worth is not precisely known because the Trump Organization is privately held.Truman was among the poorest U.S. presidents, with a net worth considerably less than $1 million. His financial situation contributed to the doubling of the presidential salary to $100,000 in 1949. In addition, the presidential pension was created in 1958 when Truman was again experiencing financial difficulties. Harry and Bess Truman received the first Medicare cards in 1966 via the Social Security Act of 1965.

Invoking: `Wikipedia` with `Joe Biden`               Page: Joe Biden     Summary: Joseph Robinette Biden Jr. (  BY-dən; born November 20, 1942) is an American politician who is the 46th and current president of the United States. Ideologically a moderate member of the Democratic Party, he previously served as the 47th vice president from 2009 to 2017 under President Barack Obama and represented Delaware in the United States Senate from 1973 to 2009.     Born in Scranton, Pennsylvania, Biden moved with his family to Delaware in 1953. He studied at the University of Delaware before earning his law degree from Syracuse University. He was elected to the New Castle County Council in 1970 and to the U.S. Senate in 1972. As a senator, Biden drafted and led the effort to pass the Violent Crime Control and Law Enforcement Act and the Violence Against Women Act. He also oversaw six U.S. Supreme Court confirmation hearings, including the contentious hearings for Robert Bork and Clarence Thomas. Biden ran unsuccessfully for the Democratic presidential nomination in 1988 and 2008. In 2008, Obama chose Biden as his running mate, and Biden was a close counselor to Obama during his two terms as vice president. In the 2020 presidential election, Biden and his running mate, Kamala Harris, defeated incumbents Donald Trump and Mike Pence. Biden is the second Catholic president in U.S. history (after John F. Kennedy), and his politics have been widely described as profoundly influenced by Catholic social teaching.     Taking office at age 78, Biden is the oldest president in U.S. history, the first to have a female vice president, and the first from Delaware. In 202"

Biden proposed the Build Back Better Act, which failed in Congress, but aspects of which were incorporated into the Inflation Reduction Act that was signed into law in 2022. Biden also signed the bipartisan CHIPS and Science Act, which focused on manufacturing, appointed Ketanji Brown Jackson to the Supreme Court and worked with congressional Republicans to prevent a first-ever national default by negotiating a deal to raise the debt ceiling. In foreign policy, Biden restored America's membership in the Paris Agreement. He oversaw the complete withdrawal of U.S. troops from Afghanistan that ended the war in Afghanistan, during which the Afghan government collapsed and the Taliban seized control. Biden has responded to the Russian invasion of Ukraine by imposing sanctions on Russia and authorizing civilian and military aid to Ukraine. During the 2023 Israel–Hamas war, Biden announced American military support for Israel, and condemned the actions of Hamas and other Palestinian militants as terrorism. In April 2023, he announced his candidacy for the Democratic Party nomination in the 2024 presidential election.          Page: Presidency of Joe Biden     Summary: Joe Biden's tenure as the 46th president of the United States began with his inauguration on January 20, 2021. Biden, a Democrat from Delaware who previously served as vice president under Barack Obama, took office following his victory in the 2020 presidential election over Republican incumbent president Donald Trump. Upon his inauguration, he became the oldest president in American history, breaking the record set by his predecessor Trump. Biden entered office amid the COVID-19 pandemic, an economic crisis, and increased political polarization.On the first day of his presidency, Biden made an effort to revert President Trump's energy policy by restoring U.S. participation in the Paris Agreement and revoking the permit for the Keystone XL pipeline. He also halted funding for Trump's border wall, an expansion of the Mexican border wall. On his second day, he issued a series of executive orders to reduce the impact of COVID-19, including invoking the Defense Production Act of 1950, and set an early goal of achieving one hundred million COVID-19 vaccinations in the United States in his first 100 days.Biden signed into law the American Rescue Plan Act of 2021; a $1.9 trillion stimulus bill that temporarily established expanded unemployment insurance and sent $1,400 stimulus checks to most Americans in response to continued economic pressure from COVID-19. He signed the bipartisan Infrastructure Investment and Jobs Act; a ten-year plan brokered by Biden alongside Democrats and Republicans in Congress, to invest in American roads, bridges, public transit, ports and broadband access. Biden signed the Juneteenth National Independence Day Act, making Juneteenth a federal holiday in the United States. He appointed Ketanji Brown Jackson to the U.S. Supreme Court—the first Black woman to serve on the court. After The Supreme Court overturned Roe v. Wade, Biden took executive actions, such as the signing of Executive Order 14076, to preserve and protect women's health rights nationwide, against abortion bans in Republican led states. Biden proposed a significant expansion of the U.S. social safety net through the Build Back Better Act, but those efforts, along with voting rights legislation, failed in Congress. However, in August 2022, Biden signed the Inflation Reduction Act of 2022, a domestic appropriations bill that included some of the provisions of the Build Back Better Act after the entire bill failed to pass. It included significant federal investment in climate and domestic clean energy production, tax credits for solar panels, electric cars and other home energy programs as well as a three-year extension of Affordable Care Act subsidies. Biden signed the CHIPS and Science Act, bolstering the semiconductor and manufacturing industry, the Honoring our PACT Act, expanding healthcare for US veterans, and the Electoral Count Reform and Presidential Transition Improvement Act. In late 2022, Biden signed the Respect for Marriage Act, which repealed the Defense of Marriage Act and codified same-sex and interracial marriage in the United States. In response to the debt-ceiling crisis of 2023, Biden negotiated and signed the Fiscal Responsibility Act of 2023, which restrains federal spending for fiscal years 2024 and 2025, implements minor changes to SNAP and TANF, includes energy permitting reform, claws back some IRS funding and unspent money for COVID-19, and suspends the debt ceiling to January 1, 2025. Biden established the American Climate Corps and created the first ever White House Office of Gun Violence Prevention. On September 26, 2023, Joe Biden visited a United Auto Workers picket line during the 2023 United Auto Workers strike, making him the first US president to visit one.     The foreign policy goal of the Biden administration is to restore the US to a ""position of trusted leadership"" among global democracies in order to address the challenges posed by Russia and China. In foreign policy, Biden completed the withdrawal of U.S. military forces from Afghanistan, declaring an end to nation-building efforts and shifting U.S. foreign policy toward strategic competition with China and, to a lesser extent, Russia. However, during the withdrawal, the Afghan government collapsed and the Taliban seized control, leading to Biden receiving bipartisan criticism. He responded to the Russian invasion of Ukraine by imposing sanctions on Russia as well as providing Ukraine with over $100 billion in combined military, economic, and humanitarian aid. Biden also approved a raid which led to the death of Abu Ibrahim al-Hashimi al-Qurashi, the leader of the Islamic State, and approved a "

Biden signed AUKUS, an international security alliance, together with Australia and the United Kingdom. Biden called for the expansion of NATO with the addition of Finland and Sweden, and rallied NATO allies in support of Ukraine. During the 2023 Israel–Hamas war, Biden condemned Hamas and other Palestinian militants as terrorism and announced American military support for Israel; Biden also showed his support and sympathy towards Palestinians affected by the war and has sent humanitarian aid.     Biden began his term with over 50% approval ratings; however, these fell significantly after the withdrawal from Afghanistan and remained low as the country experienced high inflation and rising gas prices. His age and mental fitness have also been a subject of discussion.          Page: Family of Joe Biden     Summary: Joe Biden, the 46th and current president of the United States, has family members who are prominent in law, education, activism and politics. Biden's immediate family became the first family of the United States on his inauguration on January 20, 2021.

It borders Maryland to its south and west, Pennsylvania to its north, New Jersey to its northeast, and the Atlantic Ocean to its east. The state's name derives from the adjacent Delaware Bay, which in turn was named after Thomas West, 3rd Baron De La Warr, an English nobleman and the Colony of Virginia's first colonial-era governor.Delaware occupies the northeastern portion of the Delmarva Peninsula, and some islands and territory within the Delaware River. It is the 2nd smallest and 6th least populous state, but also the 6th most densely populated. Delaware's most populous city is Wilmington, and the state's capital is Dover, the 2nd most populous city in Delaware. The state is divided into three counties, the fewest number of counties of any of the 50 U.S. states; from north to south, the three counties are: New Castle County, Kent County, and Sussex County.      The southern two counties, Kent and Sussex counties, historically have been predominantly agrarian economies/ New Castle is more urbanized and is considered part of the Delaware Valley metropolitan statistical area that surrounds and includes Philadelphia, the nation's 6th most populous city. Delaware is considered part of the Southern United States by the U.S. Census Bureau, but the state's geography, culture, and history are a hybrid of the Mid-Atlantic and Northeastern regions of the country.Before Delaware coastline was explored and developed by Europeans in the 16th century, the state was inhabited by several Native Americans tribes, including the Lenape in the north and Nanticoke in the south. The state was first colonized by Dutch traders at Zwaanendael, near present-day Lewes, Delaware, in 1631.      Delaware was one of the Thirteen Colonies that participated in the American Revolution and American Revolutionary War, in which the American Continental Army, led by George Washington, defeated the British, ended British colonization and establishing the United States as a sovereign and independent nation.      On December 7, 1787, Delaware was the first state to ratify the Constitution of the United States, earning the state the nickname ""The First State"".Since the turn of the 20th century, Delaware has become an onshore corporate haven whose corporate laws are deemed appealed to corporations; over half of all New York Stock Exchange-listed corporations and over three-fifths of the Fortune 500 is legally incorporated in the state.          Page: Delaware City, Delaware     Summary: Delaware City is a city in New Castle County, Delaware, United States. The population was 1,885 as of 2020. It is a small port town on the eastern terminus of the Chesapeake and Delaware Canal and is the location of the Forts Ferry Crossing to Fort Delaware on Pea Patch Island.          Page: Delaware River     Summary: The Delaware River is a major river in the Mid-Atlantic region of the United States and is the longest free-flowing (undammed) river in the Eastern United States. From the meeting of its branches in Hancock, New York, the river flows for 282 miles (454 km) along the borders of New York, Pennsylvania, New Jersey, and Delaware, before emptying into Delaware Bay.     The river has been recognized by the National Wildlife Federation as one of the country's Great Waters and has been called the ""Lifeblood of the Northeast"" by American Rivers. Its watershed drains an area o"

The Delaware River has two branches that rise in the Catskill Mountains of New York: the West Branch at Mount Jefferson in Jefferson, Schoharie County, and the East Branch at Grand Gorge, Delaware County. The branches merge to form the main Delaware River at Hancock, New York. Flowing south, the river remains relatively undeveloped, with 152 miles (245 km) protected as the Upper, Middle, and Lower Delaware National Scenic Rivers. At Trenton, New Jersey, the Delaware becomes tidal, navigable, and significantly more industrial. This section forms the backbone of the Delaware Valley metropolitan area, serving the port cities of Philadelphia, Camden, New Jersey, and Wilmington, Delaware. The river flows into Delaware Bay at Liston Point, 48 miles (77 km) upstream of the bay's outlet to the Atlantic Ocean between Cape May and Cape Henlopen.     Before the arrival of European settlers, the river was the homeland of the Lenape native people. They called the river Lenapewihittuk, or Lenape River, and Kithanne, meaning the largest river in this part of the country.In 1609, the river was visited by a Dutch East India Company expedition led by Henry Hudson. Hudson, an English navigator, was hired to find a western route to Cathay (China), but his encounters set the stage for Dutch colonization of North America in the 17th century. Early Dutch and Swedish settlements were established along the lower section of the river and Delaware Bay. Both colonial powers called the river the South River (Zuidrivier), compared to the Hudson River, which was known as the North River. After the English expelled the Dutch and took control of the New Netherland colony in 1664, the river was renamed Delaware after Sir Thomas West, 3rd Baron De La Warr, an English nobleman and the Virginia colony's first royal governor who defended the colony during the First Anglo-Powhatan War.          Page: Lenape     Summary: The Lenape (English: , , ; Lenape languages: [lenaːpe]), also called the Lenni Lenape and Delaware people, are an indigenous people of the Northeastern Woodlands, who live in the United States and Canada.The Lenape's historical territory included present-day northeastern Delaware, all of New Jersey, the eastern Pennsylvania regions of the Lehigh Valley and Northeastern Pennsylvania, and New York Bay, western Long Island, and the lower Hudson Valley in New York state. Today they are based in Oklahoma, Wisconsin, and Ontario.     During the last decades of the 18th century, European settlers and the effects of the American Revolutionary War displaced most Lenape from their homelands and pushed them north and west. In the 1860s, under the Indian removal policy, the U.S. federal government relocated most Lenape remaining in the Eastern United States to the Indian Territory and surrounding regions. Lenape people currently belong to the Delaware Nation and Delaware Tribe of Indians in Oklahoma, the Stockbridge–Munsee Community in Wisconsin, and the Munsee-Delaware Nation, Moravian of the Thames First Nation, and Delaware of Six Nations in Ontario.

Invoking: `Wikipedia` with `List of presidents of the United States`               Page: List of presidents of the United States     Summary: The president of the United States is the head of state and head of government of the United States, indirectly elected to a four-year term via the Electoral College. The officeholder leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces. Since the office was established in 1789, 45 men have served in 46 presidencies. The first president, George Washington, won a unanimous vote of the Electoral College. Grover Cleveland served two non-consecutive terms and is therefore counted as the 22nd and 24th president of the United States, giving rise to the discrepancy between the number of presidencies and the number of persons who have served as president. The incumbent president is Joe Biden.The presidency of William Henry Harrison, who died 31 days after taking office in 1841, was the shortest in American history. Franklin D. Roosevelt served the longest, over twelve years, before dying early in his fourth term in 1945. He is the only U.S. president to have served more than two terms. Since the ratification of the Twenty-second Amendment to the United States Constitution in 1951, no person may be elected president more than twice, and no one who has served more than two years of a term to which someone else was elected may be elected more than once.Four presidents died in office of natural causes (William Henry Harrison, Zachary Taylor, Warren G. Harding, and Franklin D. Roosevelt), four were assassinated (Abraham Lincoln, James A. Garfield, William McKinley, and John F. Kennedy), and one resigned (Richard Nixon, facing impeachment and removal from office). John Tyler was the first vice president to assume the presidency during a presidential term, and set the precedent that a vice president who does so becomes the fully functioning president with his presidency.Throughout most of its history, American politics has been dominated by political parties. The Constitution is silent on the issue of political parties, and at the time it came into force in 1789, no organized parties existed. Soon after the 1st Congress convened, political factions began rallying around dominant Washington administration officials, such as Alexander Hamilton and Thomas Jefferson. Concerned about the capacity of political parties to destroy the fragile unity holding the nation together, Washington remained unaffiliated with any political faction or party throughout his eight-year presidency. He was, and remains, the only U.S. president never affiliated with a political party.          Page: List of presidents of the United States by age     Summary: In this list of presidents of the United States by age, the first table charts the age of each president of the United States at the time of presidential inauguration (first inauguration if elected to multiple and consecutive terms), upon leaving office, and at the time of death. Where the president is still living, their lifespan and post-presidency timespan are calculated up to November 14, 2023.          Page: List of vice presidents of the United States     Summary: There have been 49 vice presidents of the United States since the office was created in 1789. Originally, the vice president was the person who received the second-most votes for president in the Electoral College. But after the election of 1800 produced a tie between Thomas Jefferson and Aaron Burr, requiring the House of Representatives to choose between them, lawmakers acted to prevent such a situation"

The Twelfth Amendment was added to the Constitution in 1804, creating the current system where electors cast a separate ballot for the vice presidency.The vice president is the first person in the presidential line of succession—that is, they assume the presidency if the president dies, resigns, or is impeached and removed from office. Nine vice presidents have ascended to the presidency in this way: eight (John Tyler, Millard Fillmore, Andrew Johnson, Chester A. Arthur, Theodore Roosevelt, Calvin Coolidge, Harry S. Truman, and Lyndon B. Johnson) through the president's death and one (Gerald Ford) through the president's resignation. The vice president also serves as the president of the Senate and may choose to cast a tie-breaking vote on decisions made by the Senate. Vice presidents have exercised this latter power to varying extents over the years.Before adoption of the Twenty-fifth Amendment in 1967, an intra-term vacancy in the office of the vice president could not be filled until the next post-election inauguration. Several such vacancies occurred: seven vice presidents died, one resigned and eight succeeded to the presidency. This amendment allowed for a vacancy to be filled through appointment by the president and confirmation by both chambers of the Congress. Since its ratification, the vice presidency has been vacant twice (both in the context of scandals surrounding the Nixon administration) and was filled both times through this process, namely in 1973 following Spiro Agnew's resignation, and again in 1974 after Gerald Ford succeeded to the presidency. The amendment also established a procedure whereby a vice president may, if the president is unable to discharge the powers and duties of the office, temporarily assume the powers and duties of the office as acting president. Three vice presidents have briefly acted as president under the 25th Amendment: George H. W. Bush on July 13, 1985; Dick Cheney on June 29, 2002, and on July 21, 2007; and Kamala Harris on November 19, 2021.     The persons who have served as vice president were born in or primarily affiliated with 27 states plus the District of Columbia. New York has produced the most of any state as eight have been born there and three others considered it their home state. Most vice presidents have been in their 50s or 60s and had political experience before assuming the office. Two vice presidents—George Clinton and John C. Calhoun—served under more than one president. Ill with tuberculosis and recovering in Cuba on Inauguration Day in 1853, William R. King, by an Act of Congress, was allowed to take the oath outside the United States. He is the only vice president to take his oath of office in a foreign country.          Page: List of presidents of the United States by net worth     Summary: The list of presidents of the United States by net worth at peak varies greatly. Debt and depreciation often means that presidents' net worth is less than $0 at the time of death. Most presidents before 1845 were extremely wealthy, especially Andrew Jackson and George Washington.         Presidents since 1929, when Herbert Hoover took office, have generally been wealthier than presidents of the late nineteenth and early twentieth centuries; with the exception of Harry S. Truman, all presidents since this time have been millionaires. These presidents have often received income from autobiographies and other writing. Except for Franklin D. Roosevelt and John F. Kennedy (both of whom died while in office), all presidents beginning with Calvin Coolidge have written autobiographies. In addition, many presidents—including Bill Clinton—have earned considerable income from public speaking after leaving office.The richest president in history may be Donald Trump. However, his net worth is not precisely known because the Trump Organization is privately held.Truman was among the poorest U.S. presidents, with a net worth considerably less than $1 million. His financial situation contributed to the doubling of the presidential salary to $100,000 in 1949. In addition, the presidential pension was created in 1958 when Truman was again experiencing financial difficulties. Harry and Bess Truman received the first Medicare cards in 1966 via the Social Security Act of 1965.

Taking office at age 78, Biden is the oldest president in U.S. history, the first to have a female vice president, and the first from Delaware. In 2021, he signed a bipartisan infrastructure bill, as well as a $1.9 trillion economic stimulus package in response to the COVID-19 pandemic and its related recession. Biden proposed the Build Back Better Act, which failed in Congress, but aspects of which were incorporated into the Inflation Reduction Act that was signed into law in 2022. Biden also signed the bipartisan CHIPS and Science Act, which focused on manufacturing, appointed Ketanji Brown Jackson to the Supreme Court and worked with congressional Republicans to prevent a first-ever national default by negotiating a deal to raise the debt ceiling. In foreign policy, Biden restored America's membership in the Paris Agreement. He oversaw the complete withdrawal of U.S. troops from Afghanistan that ended the war in Afghanistan, during which the Afghan government collapsed and the Taliban seized control.

Page: Presidency of Joe Biden     Summary: Joe Biden's tenure as the 46th president of the United States began with his inauguration on January 20, 2021. Biden, a Democrat from Delaware who previously served as vice president under Barack Obama, took office following his victory in the 2020 presidential election over Republican incumbent president Donald Trump. Upon his inauguration, he became the oldest president in American history, breaking the record set by his predecessor Trump. Biden entered office amid the COVID-19 pandemic, an economic crisis, and increased political polarization.On the first day of his presidency, Biden made an effort to revert President Trump's energy policy by restoring U.S. participation in the Paris Agreement and revoking the permit for the Keystone XL pipeline. He also halted funding for Trump's border wall, an expansion of the Mexican border wall. On his second day, he issued a series of executive orders to reduce the impact of COVID-19, including invoking the Defense Production Act of 1950, and set an early goal of achieving one hundred million COVID-19 vaccinations in the United States in his first 100 days.Biden signed into law the American Rescue Plan Act of 2021; a $1.9 trillion stimulus bill that temporarily established expanded unemployment insurance and sent $1,400 stimulus checks to most Americans in response to continued economic pressure from COVID-19. He signed the bipartisan Infrastructure Investment and Jobs Act; a ten-year plan brokered by Biden alongside Democrats and Republicans in Congress, to invest in American roads, bridges, public transit, ports and broadband access. Biden signed the Juneteenth National Independence Day Act, making Juneteenth a federal holiday in the United States. He appointed Ketanji Brown Jackson to the U.S. Supreme Court—the first Black woman to serve on the court. After The Supreme Court overturned Roe v. Wade, Biden took executive actions, such as the signing of Executive Order 14076, to preserve and protect women's health rights nationwide, against abortion bans in Republican led states. Biden proposed a significant expansion of the U.S. social safety net through the Build Back Better Act, but those efforts, along with voting rights legislation, failed in Congress. However, in August 2022, Biden signed the Inflation Reduction Act of 2022, a domestic appropriations bill that included some of the provisions of the Build Back Better Act after the entire bill failed to pass. It included significant federal investment in climate and domestic clean energy production, tax credits for solar panels, electric cars and other home energy programs as well as a three-year extension of Affordable Care Act subsidies. Biden signed the CHIPS and Science Act, bolstering the semiconductor and manufacturing industry, the Honoring our PACT Act, expanding healthcare for US veterans, and the Electoral Count Reform and Presidential Transition Improvement Act.

In foreign policy, Biden completed the withdrawal of U.S. military forces from Afghanistan, declaring an end to nation-building efforts and shifting U.S. foreign policy toward strategic competition with China and, to a lesser extent, Russia. However, during the withdrawal, the Afghan government collapsed and the Taliban seized control, leading to Biden receiving bipartisan criticism. He responded to the Russian invasion of Ukraine by imposing sanctions on Russia as well as providing Ukraine with over $100 billion in combined mili"

It borders Maryland to its south and west, Pennsylvania to its north, New Jersey to its northeast, and the Atlantic Ocean to its east. The state's name derives from the adjacent Delaware Bay, which in turn was named after Thomas West, 3rd Baron De La Warr, an English nobleman and the Colony of Virginia's first colonial-era governor.Delaware occupies the northeastern portion of the Delmarva Peninsula, and some islands and territory within the Delaware River. It is the 2nd smallest and 6th least populous state, but also the 6th most densely populated. Delaware's most populous city is Wilmington, and the state's capital is Dover, the 2nd most populous city in Delaware. The state is divided into three counties, the fewest number of counties of any of the 50 U.S. states; from north to south, the three counties are: New Castle County, Kent County, and Sussex County.      The southern two counties, Kent and Sussex counties, historically have been predominantly agrarian economies/ New Castle is more urbanized and is considered part of the Delaware Valley metropolitan statistical area that surrounds and includes Philadelphia, the nation's 6th most populous city. Delaware is considered part of the Southern United States by the U.S. Census Bureau, but the state's geography, culture, and history are a hybrid of the Mid-Atlantic and Northeastern regions of the country.Before Delaware coastline was explored and developed by Europeans in the 16th century, the state was inhabited by several Native Americans tribes, including the Lenape in the north and Nanticoke in the south. The state was first colonized by Dutch traders at Zwaanendael, near present-day Lewes, Delaware, in 1631.      Delaware was one of the Thirteen Colonies that participated in the American Revolution and American Revolutionary War, in which the American Continental Army, led by George Washington, defeated the British, ended British colonization and establishing the United States as a sovereign and independent nation.      On December 7, 1787, Delaware was the first state to ratify the Constitution of the United States, earning the state the nickname ""The First State"".Since the turn of the 20th century, Delaware has become an onshore corporate haven whose corporate laws are deemed appealed to corporations; over half of all New York Stock Exchange-listed corporations and over three-fifths of the Fortune 500 is legally incorporated in the state.

Its watershed drains an area of 13,539 square miles (35,070 km2) and provides drinking water for 17 million people, including half of New York City via the Delaware Aqueduct.     The Delaware River has two branches that rise in the Catskill Mountains of New York: the West Branch at Mount Jefferson in Jefferson, Schoharie County, and the East Branch at Grand Gorge, Delaware County. The branches merge to form the main Delaware River at Hancock, New York. Flowing south, the river remains relatively undeveloped, with 152 miles (245 km) protected as the Upper, Middle, and Lower Delaware National Scenic Rivers. At Trenton, New Jersey, the Delaware becomes tidal, navigable, and significantly more industrial. This section forms the backbone of the Delaware Valley metropolitan area, serving the port cities of Philadelphia, Camden, New Jersey, and Wilmington, Delaware. The river flows into Delaware Bay at Liston Point, 48 miles (77 km) upstream of the bay's outlet to the Atlantic Ocean between Cape May and Cape Henlopen.     Before the arrival of European settlers, the river was the homeland of the Lenape native people. They called the river Lenapewihittuk, or Lenape River, and Kithanne, meaning the largest river in this part of the country.In 1609, the river was visited by a Dutch East India Company expedition led by Henry Hudson. Hudson, an English navigator, was hired to find a western route to Cathay (China), but his encounters set the stage for Dutch colonization of North America in the 17th century. Early Dutch and Swedish settlements were established along the lower section of the river and Delaware Bay. Both colonial powers called the river the South River (Zuidrivier), compared to the Hudson River, which was known as the North River. After the English expelled the Dutch and took control of the New Netherland colony in 1664, the river was renamed Delaware after Sir Thomas West, 3rd Baron De La Warr, an English nobleman and the Virginia colony's first royal governor who defended the colony during the First Anglo-Powhatan War.          Page: Lenape     Summary: The Lenape (English: , , ; Lenape languages: [lenaːpe]), also called the Lenni Lenape and Delaware people, are an indigenous people of the Northeastern Woodlands, who live in the United States and Canada.The Lenape's historical territory included present-day northeastern Delaware, all of New Jersey, the eastern Pennsylvania regions of the Lehigh Valley and Northeastern Pennsylvania, and New York Bay, western Long Island, and the lower Hudson Valley in New York state. Today they are based in Oklahoma, Wisconsin, and Ontario.     During the last decades of the 18th century, European settlers and the effects of the American Revolutionary War displaced most Lenape from their homelands and pushed them north and west. In the 1860s, under the Indian removal policy, the U.S. federal government relocated most Lenape remaining in the Eastern United States to the Indian Territory and surrounding regions. Lenape people currently belong to the Delaware Nation and Delaware Tribe of Indians in Oklahoma, the Stockbridge–Munsee Community in Wisconsin, and the Munsee-Delaware Nation, Moravian of the Thames First Nation, and Delaware of Six Nations in Ontario.

Get started | 🦜️🔗 Langchain,https://python.langchain.com/docs/expression_language/get_started,langchain_docs,"Main:  On this page LCEL makes it easy to build complex chains from basic components, and supports out of the box functionality such as streaming, parallelism, and logging.  ##Basic example: prompt + model + output parser[​](#basic-example-prompt--model--output-parser) The most basic and common use case is chaining a prompt template and a model together. To see how this works, let's create a chain that takes a topic and generates a joke:  from langchain.chat_models import ChatOpenAI from langchain.prompts import ChatPromptTemplate from langchain.schema.output_parser import StrOutputParser  prompt = ChatPromptTemplate.from_template(""tell me a short joke about {topic}"") model = ChatOpenAI() output_parser = StrOutputParser()  chain = prompt | model | output_parser  chain.invoke({""topic"": ""ice cream""})      ""Why did the ice cream go to therapy?\n\nBecause it had too many toppings and couldn't find its cone-fidence!""  Notice this line of this code, where we piece together then different components into a single chain using LCEL:  chain = prompt | model | output_parser  The | symbol is similar to a [unix pipe operator](https://en.wikipedia.org/wiki/Pipeline_(Unix)), which chains together the different components feeds the output from one component as input into the next component.  In this chain the user input is passed to the prompt template, then the prompt template output is passed to the model, then the model output is passed to the output parser. Let's take a look at each component individually to really understand what's going on.  ###1. Prompt[​](#1-prompt) prompt is a BasePromptTemplate, which means it takes in a dictionary of template variables and produces a PromptValue. A PromptValue is a wrapper around a completed prompt that can be passed to either an LLM (which takes a string as input) or ChatModel (which takes a sequence of messages as input). It can work with either language model type because it defines logic both for producing BaseMessages and for producing a string.  prompt_value = prompt.invoke({""topic"": ""ice cream""}) prompt_value      ChatPromptValue(messages=[HumanMessage(content='tell me a short joke about ice cream')])  prompt_value.to_messages()      [HumanMessage(content='tell me a short joke about ice cream')]  prompt_value.to_string()      'Human: tell me a short joke about ice cream'  ###2. Model[​](#2-model) The PromptValue is then passed to model. In this case our model is a ChatModel, meaning it will output a BaseMessage.  message = model.invoke(prompt_value) message      AIMessage(content=""Why did the ice cream go to therapy? \n\nBecause it had too many toppings and couldn't find its cone-fidence!"")  If our model was an LLM, it would output a string.  from langchain.llms import OpenAI  llm = OpenAI(model=""gpt-3.5-turbo-instruct"") llm.invoke(prompt_value)      '\n\nRobot: Why did the ice cream go to therapy? Because it had a rocky road.'  ###3. Output parser[​](#3-output-parser) And lastly we pass our model output to the output_parser, which is a BaseOutputParser meaning it takes either a string or a BaseMessage as input. The StrOutputParser specifically simple converts any input into a string.  output_parser.invoke(message)      ""Why did the ice cream go to therapy? \n\nBecause it had too many toppings and couldn't find its cone-fidence!""  ###4. Entire Pipeline[​](#4-entire-pipeline) To follow the steps along:  - We pass in user input on the desired topic as {""topic"": ""ice cream""} - The prompt component takes the user input, which is then used to construct a PromptValue after using the topic to construct the prompt. - The model component takes the generated prompt, and passes into the OpenAI LLM model for evaluation. The generated output from the model is a ChatMessage object. - Finally, the output_parser component takes in a ChatMessage, and transforms this into a Python string, which is returned from the invoke method. INFO Note that if you’re curious about the output of any components, you can always test out a smaller version of the chain such as prompt or prompt | model to see the intermediate results:  input = {""topic"": ""ice cream""}  prompt.invoke(input) # > ChatPromptValue(messages=[HumanMessage(content='tell me a short joke about ice cream')])  (prompt | model).invoke(input) # > AIMessage(content=""Why did the ice cream go to therapy?\nBecause it had too many toppings and couldn't cone-trol itself!"")  ##RAG Search Example[​](#rag-search-example) For our next example, we want to run a retrieval-augmented generation chain to add some context when responding to questions.  # Requires: # pip install langchain docarray  from langchain.chat_models import ChatOpenAI from langchain.embeddings import OpenAIEmbeddings from langchain.prompts import ChatPromptTemplate from langchain.schema.output_parser import StrOutputParser from langchain.schema.runnable import RunnableParallel, RunnablePassthrough from langchain.vectorstores import DocArrayInMemorySearch  vectorstore = DocArrayInMemorySearch.from_texts(     [""harrison worked at kensho"", ""bears like to eat honey""],     embedding=OpenAIEmbeddings(), ) retriever = vectorstore.as_retriever()  template = """"""Answer the question based only on the following context: {context}  Question: {question} """""" prompt = ChatPromptTemplate.from_template(template) model = ChatOpenAI() output_parser = StrOutputParser()  setup_and_retrieval = RunnableParallel(     {""context"": retriever, ""question"": RunnablePassthrough()} ) chain = setup_and_retrieval | prompt | model | output_parser  chain.invoke(""where did harrison work?"")  In this case, the composed chain is:  chain = setup_and_retrieval | prompt | model | output_parser  To explain this, we first can see that the prompt template above takes in context and question as values to be substituted in the prompt. Before building the prompt template, we want to retrieve relevant documents to the search and include them as part of the context.  As a preliminary step, we’ve setup the retrieve"
Get started | 🦜️🔗 Langchain,https://python.langchain.com/docs/expression_language/get_started,langchain_docs,"r using an in memory store, which can retrieve documents based on a query. This is a runnable component as well that can be chained together with other components, but you can also try to run it separately:  retriever.invoke(""where did harrison work?"")  We then use the RunnableParallel to prepare the expected inputs into the prompt by using the entries for the retrieved documents as well as the original user question, using the retriever for document search, and RunnablePassthrough to pass the user’s question:  setup_and_retrieval = RunnableParallel(     {""context"": retriever, ""question"": RunnablePassthrough()} )  To review, the complete chain is:  setup_and_retrieval = RunnableParallel(     {""context"": retriever, ""question"": RunnablePassthrough()} ) chain = setup_and_retrieval | prompt | model | output_parser  With the flow being:  - The first steps create a RunnableParallel object with two entries. The first entry, context will include the document results fetched by the retriever. The second entry, question will contain the user’s original question. To pass on the question, we use RunnablePassthrough to copy this entry. - Feed the dictionary from the step above to the prompt component. It then takes the user input which is question as well as the retrieved document which is context to construct a prompt and output a PromptValue. - The model component takes the generated prompt, and passes into the OpenAI LLM model for evaluation. The generated output from the model is a ChatMessage object. - Finally, the output_parser component takes in a ChatMessage, and transforms this into a Python string, which is returned from the invoke method. ##Next steps[​](#next-steps) We recommend reading our [Why use LCEL](/docs/expression_language/why) section next to see a side-by-side comparison of the code needed to produce common functionality with and without LCEL.

Add fallbacks | 🦜️🔗 Langchain,https://python.langchain.com/docs/expression_language/how_to/fallbacks,langchain_docs,"Main:  On this page #Add fallbacks There are many possible points of failure in an LLM application, whether that be issues with LLM API's, poor model outputs, issues with other integrations, etc. Fallbacks help you gracefully handle and isolate these issues.  Crucially, fallbacks can be applied not only on the LLM level but on the whole runnable level.  ##Handling LLM API Errors[​](#handling-llm-api-errors) This is maybe the most common use case for fallbacks. A request to an LLM API can fail for a variety of reasons - the API could be down, you could have hit rate limits, any number of things. Therefore, using fallbacks can help protect against these types of things.  IMPORTANT: By default, a lot of the LLM wrappers catch errors and retry. You will most likely want to turn those off when working with fallbacks. Otherwise the first wrapper will keep on retrying and not failing.  from langchain.chat_models import ChatAnthropic, ChatOpenAI  First, let's mock out what happens if we hit a RateLimitError from OpenAI  from unittest.mock import patch  from openai.error import RateLimitError  # Note that we set max_retries = 0 to avoid retrying on RateLimits, etc openai_llm = ChatOpenAI(max_retries=0) anthropic_llm = ChatAnthropic() llm = openai_llm.with_fallbacks([anthropic_llm])  # Let's use just the OpenAI LLm first, to show that we run into an error with patch(""openai.ChatCompletion.create"", side_effect=RateLimitError()):     try:         print(openai_llm.invoke(""Why did the chicken cross the road?""))     except:         print(""Hit error"")      Hit error  # Now let's try with fallbacks to Anthropic with patch(""openai.ChatCompletion.create"", side_effect=RateLimitError()):     try:         print(llm.invoke(""Why did the chicken cross the road?""))     except:         print(""Hit error"")      content=' I don\'t actually know why the chicken crossed the road, but here are some possible humorous answers:\n\n- To get to the other side!\n\n- It was too chicken to just stand there. \n\n- It wanted a change of scenery.\n\n- It wanted to show the possum it could be done.\n\n- It was on its way to a poultry farmers\' convention.\n\nThe joke plays on the double meaning of ""the other side"" - literally crossing the road to the other side, or the ""other side"" meaning the afterlife.

Parallelize steps | 🦜️🔗 Langchain,https://python.langchain.com/docs/expression_language/how_to/map,langchain_docs,"Main:  On this page #Parallelize steps RunnableParallel (aka.

'Harrison worked at Kensho.'  Here the input to prompt is expected to be a map with keys ""context"" and ""question"". The user input is just the question. So we need to get the context using our retriever and passthrough the user input under the ""question"" key.  Note that when composing a RunnableParallel with another Runnable we don't even need to wrap our dictionary in the RunnableParallel class — the type conversion is handled for us.  ##Parallelism[​](#parallelism) RunnableParallel are also useful for running independent processes in parallel, since each Runnable in the map is executed in parallel. For example, we can see our earlier joke_chain, poem_chain and map_chain all have about the same runtime, even though map_chain executes both of the other two.  joke_chain.invoke({""topic"": ""bear""})      958 ms ± 402 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)  poem_chain.invoke({""topic"": ""bear""})      1.22 s ± 508 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)  map_chain.invoke({""topic"": ""bear""})      1.15 s ± 119 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)    "

As she famously wrote, ""One is not born, but rather becomes, a woman.""\n\n- De Beauvoir believed that while individuals are situated in certain cultural contexts and social conditions, they still have agency and the ability to transcend these situations. Freedom comes from choosing one\'s attitude toward these constraints.\n\n- She emphasized the radical freedom and responsibility of the individual. We are ""condemned to be free"" because we cannot escape making choices and taking responsibility for our choices. \n\n- De Beauvoir felt that many people evade their freedom and responsibility by adopting rigid mindsets, ideologies, or conforming uncritically to social roles.\n\n- She advocated for the recognition of ambiguity in the human condition and warned against the quest for absolute rules that deny freedom and responsibility.

De Beauvoir focused more on its positive potential.\n\n- De Beauvoir critiqued Sartre's premise that human relations are necessarily conflictual.

Dynamically route logic based on input | 🦜️🔗 Langchain,https://python.langchain.com/docs/expression_language/how_to/routing,langchain_docs,"Main:  On this page #Dynamically route logic based on input This notebook covers how to do routing in the LangChain Expression Language.  Routing allows you to create non-deterministic chains where the output of a previous step defines the next step. Routing helps provide structure and consistency around interactions with LLMs.  There are two ways to perform routing:  - Using a RunnableBranch. - Writing custom factory function that takes the input of a previous step and returns a runnable. Importantly, this should return a runnable and NOT actually execute. We'll illustrate both methods using a two step sequence where the first step classifies an input question as being about LangChain, Anthropic, or Other, then routes to a corresponding prompt chain.  ##Using a RunnableBranch[​](#using-a-runnablebranch) A RunnableBranch is initialized with a list of (condition, runnable) pairs and a default runnable. It selects which branch by passing each condition the input it's invoked with. It selects the first condition to evaluate to True, and runs the corresponding runnable to that condition with the input.  If no provided conditions match, it runs the default runnable.  Here's an example of what it looks like in action:  from langchain.chat_models import ChatAnthropic from langchain.prompts import PromptTemplate from langchain.schema.output_parser import StrOutputParser  First, let's create a chain that will identify incoming questions as being about LangChain, Anthropic, or Other:  chain = (     PromptTemplate.from_template(         """"""Given the user question below, classify it as either being about `LangChain`, `Anthropic`, or `Other`.

Some examples of interactions:\n\n- Ask general knowledge questions and LangChain will try to answer factually.

You can prompt the start of a conversation by saying something like ""Let\'s discuss machine learning""\n\n- Ask for summaries or high-level explanations on subjects. For example ""Can you summarize the main themes in Shakespeare\'s Hamlet?"" \n\n- Give creative writing prompts or requests to have LangChain generate text in different styles. For example ""Write a short children\'s story about a mouse"" or ""Generate a poem in the style of Robert Frost about nature""\n\n- Correct LangChain if it makes an inaccurate statement and provide the right information.

Interface | 🦜️🔗 Langchain,https://python.langchain.com/docs/expression_language/interface,langchain_docs,"Main:  On this page To make it as easy as possible to create custom chains, we've implemented a [""Runnable""](https://api.python.langchain.com/en/stable/runnables/langchain_core.runnables.base.Runnable.html#langchain_core.runnables.base.Runnable) protocol.

For example, when using a RunnableParallel (often written as a dictionary) it executes each element in parallel.  from langchain.schema.runnable import RunnableParallel  chain1 = ChatPromptTemplate.from_template(""tell me a joke about {topic}"") | model chain2 = (     ChatPromptTemplate.from_template(""write a short (2 line) poem about {topic}"")     | model ) combined = RunnableParallel(joke=chain1, poem=chain2)  chain1.invoke({""topic"": ""bears""})      CPU times: user 54.3 ms, sys: 0 ns, total: 54.3 ms     Wall time: 2.29 s          AIMessage(content=""Why don't bears wear shoes?\n\nBecause they already have bear feet!"")  chain2.invoke({""topic"": ""bears""})      CPU times: user 7.8 ms, sys: 0 ns, total: 7.8 ms     Wall time: 1.43 s          AIMessage(content=""In wild embrace,\nNature's strength roams with grace."")  combined.invoke({""topic"": ""bears""})      CPU times: user 167 ms, sys: 921 µs, total: 168 ms     Wall time: 1.56 s          {'joke': AIMessage(content=""Why don't bears wear shoes?\n\nBecause they already have bear feet!""),      'poem': AIMessage(content=""Fierce and wild, nature's might,\nBears roam the woods, shadows of the night."")}  ###Parallelism on batches[​](#parallelism-on-batches) Parallelism can be combined with other runnables. Let's try to use parallelism with batches.  chain1.batch([{""topic"": ""bears""}, {""topic"": ""cats""}])      CPU times: user 159 ms, sys: 3.66 ms, total: 163 ms     Wall time: 1.34 s          [AIMessage(content=""Why don't bears wear shoes?\n\nBecause they already have bear feet!""),      AIMessage(content=""Sure, here's a cat joke for you:\n\nWhy don't cats play poker in the wild?\n\nBecause there are too many cheetahs!"")]  chain2.batch([{""topic"": ""bears""}, {""topic"": ""cats""}])      CPU times: user 165 ms, sys: 0 ns, total: 165 ms     Wall time: 1.73 s          [AIMessage(content=""Silent giants roam,\nNature's strength, love's emblem shown.""),      AIMessage(content='Whiskers aglow, paws tiptoe,\nGraceful hunters, hearts aglow.')]  combined.batch([{""topic"": ""bears""}, {""topic"": ""cats""}])      CPU times: user 507 ms, sys: 125 ms, total: 632 ms     Wall time: 1.49 s          [{'joke': AIMessage(content=""Why don't bears wear shoes?\n\nBecause they already have bear feet!""),       'poem': AIMessage(content=""Majestic bears roam,\nNature's wild guardians of home."")},      {'joke': AIMessage(content=""Sure, here's a cat joke for you:\n\nWhy did the cat sit on the computer?\n\nBecause it wanted to keep an eye on the mouse!""),       'poem': AIMessage(content='Whiskers twitch, eyes gleam,\nGraceful creatures, feline dream.')}]    "
Why use LCEL | 🦜️🔗 Langchain,https://python.langchain.com/docs/expression_language/why,langchain_docs,"Main:  On this page WE RECOMMEND READING THE LCEL [GET STARTED](/DOCS/EXPRESSION_LANGUAGE/GET_STARTED) SECTION FIRST. LCEL makes it easy to build complex chains from basic components. It does this by providing:  - A unified interface: Every LCEL object implements the Runnable interface, which defines a common set of invocation methods (invoke, batch, stream, ainvoke, ...). This makes it possible for chains of LCEL objects to also automatically support these invocations. That is, every chain of LCEL objects is itself an LCEL object. - Composition primitives: LCEL provides a number of primitives that make it easy to compose chains, parallelize components, add fallbacks, dynamically configure chain internal, and more. To better understand the value of LCEL, it's helpful to see it in action and think about how we might recreate similar functionality without it. In this walkthrough we'll do just that with our [basic example](/docs/expression_language/get_started#basic_example) from the get started section. We'll take our simple prompt + model chain, which under the hood already defines a lot of functionality, and see what it would take to recreate all of it.  from langchain.chat_models import ChatOpenAI from langchain.prompts import ChatPromptTemplate from langchain.schema.output_parser import StrOutputParser   prompt = ChatPromptTemplate.from_template(""Tell me a short joke about {topic}"") model = ChatOpenAI(model=""gpt-3.5-turbo"") output_parser = StrOutputParser()  chain = prompt | model | output_parser  ##Invoke[​](#invoke) In the simplest case, we just want to pass in a topic string and get

response.choices[0].message.content  def invoke_chain(topic: str) -> str:     prompt_value = prompt_template.format(topic=topic)     messages = [{""role"": ""user"", ""content"": prompt_value}]

flush=True)  ####LCEL[​](#lcel-1) for chunk in chain.stream(""ice cream""):     print(chunk, end="""", flush=True)  ##Batch[​](#batch) If we want to run on a batch of inputs in parallel, we'll again

await ainvoke_chain(""ice cream"")  ####LCEL[​](#lcel-3) chain.ainvoke(""ice cream"")  ##LLM instead of chat model[​](#llm-instead-of-chat-model) If we want to use a completion endpoint instead of a

Introduction | 🦜️🔗 Langchain,https://python.langchain.com/docs/get_started/introduction,langchain_docs,"Main:  On this page #Introduction LangChain is a framework for developing applications powered by language models. It enables applications that:  - Are context-aware: connect a language model to sources of context (prompt instructions, few shot examples, content to ground its response in, etc.) - Reason: rely on a language model to reason (about how to answer based on provided context, what actions to take, etc.) This framework consists of several parts.  - LangChain Libraries: The Python and JavaScript libraries. Contains interfaces and integrations for a myriad of components, a basic run time for combining these components into chains and agents, and off-the-shelf implementations of chains and agents. - [LangChain Templates](/docs/templates): A collection of easily deployable reference architectures for a wide variety of tasks. - [LangServe](/docs/langserve): A library for deploying LangChain chains as a REST API. - [LangSmith](/docs/langsmith): A developer platform that lets you debug, test, evaluate, and monitor chains built on any LLM framework and seamlessly integrates with LangChain.   Together, these products simplify the entire application lifecycle:  - Develop: Write your applications in LangChain/LangChain.js. Hit the ground running using Templates for reference. - Productionize: Use LangSmith to inspect, test and monitor your chains, so that you can constantly improve and deploy with confidence. - Deploy: Turn any chain into an API with LangServe. ##LangChain Libraries[​](#langchain-libraries) The main value props of the LangChain packages are:  - Components: composable tools and integrations for working with language models. Components are modular and easy-to-use, whether you are using the rest of the LangChain framework or not - Off-the-shelf chains: built-in assemblages of components for accomplishing higher-level tasks Off-the-shelf chains make it easy to get started. Components make it easy to customize existing chains and build new ones.  ##Get started[​](#get-started) [Here’s](/docs/get_started/installation) how to install LangChain, set up your environment, and start building.  We recommend following our [Quickstart](/docs/get_started/quickstart) guide to familiarize yourself with the framework by building your first LangChain application.

Quickstart | 🦜️🔗 Langchain,https://python.langchain.com/docs/get_started/quickstart,langchain_docs,"Main:  Skip to main content  🦜️🔗 LangChain  Search CTRLK Get startedQuickstart On this page Quickstart In this quickstart we'll show you how to:  Get setup with LangChain, LangSmith and LangServe Use the most basic and common components of LangChain: prompt templates, models, and output parsers Use LangChain Expression Language, the protocol that LangChain is built on and which facilitates component chaining Build a simple application with LangChain Trace your application with LangSmith Serve your application with LangServe That's a fair amount to cover! Let's dive in.  Setup​ Installation​ To install LangChain run:  Pip Conda pip install langchain  For more details, see our Installation guide.  Environment​ Using LangChain will usually require integrations with one or more model providers, data stores, APIs, etc. For this example, we'll use OpenAI's model APIs.  First we'll need to install their Python package:  pip install openai  Accessing the API requires an API key, which you can get by creating an account and heading here. Once we have a key we'll want to set it as an environment variable by running:  export OPENAI_API_KEY=""...""  If you'd prefer not to set an environment variable you can pass the key in directly via the openai_api_key named parameter when initiating the OpenAI LLM class:  from langchain.chat_models import ChatOpenAI  llm = ChatOpenAI(openai_api_key=""..."")  LangSmith​ Many of the applications you build with LangChain will contain multiple steps with multiple invocations of LLM calls. As these applications get more and more complex, it becomes crucial to be able to inspect what exactly is going on inside your chain or agent. The best way to do this is with LangSmith.  Note that LangSmith is not needed, but it is helpful. If you do want to use LangSmith, after you sign up at the link above, make sure to set your environment variables to start logging traces:  export LANGCHAIN_TRACING_V2=""true"" export LANGCHAIN_API_KEY=...  LangServe​ LangServe helps developers deploy LangChain chains as a REST API. You do not need to use LangServe to use LangChain, but in this guide we'll show how you can deploy your app with LangServe.  Install with:  pip install ""langserve[all]""  Building with LangChain​ LangChain provides many modules that can be used to build language model applications. Modules can be used as standalones in simple applications and they can be composed for more complex use cases. Composition is powered by LangChain Expression Language (LCEL), which defines a unified Runnable interface that many modules implement, making it possible to seamlessly chain components.  The simplest and most common chain contains three things:  LLM/Chat Model: The language model is the core reasoning engine here. In order to work with LangChain, you need to understand the different types of language models and how to work with them. Prompt Template: This provides instructions to the language model. This controls what the language model outputs, so understanding how to construct prompts and different prompting strategies is crucial. Output Parser: These translate the raw response from the language model to a more workable format, making it easy to use the output downstream. In this guide we'll cover those three components individually, and then go over how to combine them. Understanding these concepts will set you up well for being able to use and customize LangChain applications. Most LangChain applications allow you to configure the model and/or the prompt, so knowing how to take advantage of this will be a big enabler.  LLM / Chat Model​ There are two types of language models:  LLM: underlying model takes a string as input and returns a string ChatModel: underlying model takes a list of messages as input and returns a message Strings are simple, but what exactly are messages? The base message interface is defined by BaseMessage, which has two required attributes:  content: The content of the message. Usually a string. role: The entity from which the BaseMessage is coming. LangChain provides several objects to easily distinguish between different roles:  HumanMessage: A BaseMessage coming from a human/user. AIMessage: A BaseMessage coming from an AI/assistant. SystemMessage: A BaseMessage coming from the system. FunctionMessage / ToolMessage: A BaseMessage containing the output of a function or tool call. If none of those roles sound right, there is also a ChatMessage class where you can specify the role manually.  LangChain provides a common interface that's shared by both LLMs and ChatModels. However it's useful to understand the difference in order to most effectively construct prompts for a given language model.  The simplest way to call an LLM or ChatModel is using .invoke(), the universal synchronous call method for all LangChain Expression Language (LCEL) objects:  LLM.invoke: Takes in a string, returns a string. ChatModel.invoke: Takes in a list of BaseMessage, returns a BaseMessage. The input types for these methods are actually more general than this, but for simplicity here we can assume LLMs only take strings and Chat models only takes lists of messages. Check out the ""Go deeper"" section below to learn more about model invocation.  Let's see how to work with these different types of models and these different types of inputs. First, let's import an LLM and a ChatModel.  from langchain.llms import OpenAI from langchain.chat_models import ChatOpenAI  llm = OpenAI() chat_model = ChatOpenAI()  LLM and ChatModel objects are effectively configuration objects. You can initialize them with parameters like temperature and others, and pass them around.  from langchain.schema import HumanMessage  text = ""What would be a good company name for a company that makes colorful socks?"" messages = [HumanMessage(content=text)]  llm.invoke(text) # >> Feetful of Fun  chat_model.invoke(messages) # >> AIMessage(content=""Socks O'Color"")  Go deeper Prompt templates​ Most LLM applications do not pass"
Quickstart | 🦜️🔗 Langchain,https://python.langchain.com/docs/get_started/quickstart,langchain_docs," user input directly into an LLM. Usually they will add the user input to a larger piece of text, called a prompt template, that provides additional context on the specific task at hand.  In the previous example, the text we passed to the model contained instructions to generate a company name. For our application, it would be great if the user only had to provide the description of a company/product, without having to worry about giving the model instructions.  PromptTemplates help with exactly this! They bundle up all the logic for going from user input into a fully formatted prompt. This can start off very simple - for example, a prompt to produce the above string would just be:  from langchain.prompts import PromptTemplate  prompt = PromptTemplate.from_template(""What is a good name for a company that makes {product}?"") prompt.format(product=""colorful socks"")  What is a good name for a company that makes colorful socks?  However, the advantages of using these over raw string formatting are several. You can ""partial"" out variables - e.g. you can format only some of the variables at a time. You can compose them together, easily combining different templates into a single prompt. For explanations of these functionalities, see the section on prompts for more detail.  PromptTemplates can also be used to produce a list of messages. In this case, the prompt not only contains information about the content, but also each message (its role, its position in the list, etc.). Here, what happens most often is a ChatPromptTemplate is a list of ChatMessageTemplates. Each ChatMessageTemplate contains instructions for how to format that ChatMessage - its role, and then also its content. Let's take a look at this below:  from langchain.prompts.chat import ChatPromptTemplate  template = ""You are a helpful assistant that translates {input_language} to {output_language}."" human_template = ""{text}""  chat_prompt = ChatPromptTemplate.from_messages([     (""system"", template),     (""human"", human_template), ])  chat_prompt.format_messages(input_language=""English"", output_language=""French"", text=""I love programming."")  [     SystemMessage(content=""You are a helpful assistant that translates English to French."", additional_kwargs={}),     HumanMessage(content=""I love programming."") ]  ChatPromptTemplates can also be constructed in other ways - see the section on prompts for more detail.  Output parsers​ OutputParsers convert the raw output of a language model into a format that can be used downstream. There are few main types of OutputParsers, including:  Convert text from LLM into structured information (e.g. JSON) Convert a ChatMessage into just a string Convert the extra information returned from a call besides the message (like OpenAI function invocation) into a string. For full information on this, see the section on output parsers.  In this getting started guide, we will write our own output parser - one that converts a comma separated list into a list.  from langchain.schema import BaseOutputParser  class CommaSeparatedListOutputParser(BaseOutputParser):     """"""Parse the output of an LLM call to a comma-separated list.""""""       def parse(self, text: str):         """"""Parse the output of an LLM call.""""""         return text.strip().split("", "")  CommaSeparatedListOutputParser().parse(""hi, bye"") # >> ['hi', 'bye']  Composing with LCEL​ We can now combine all these into one chain. This chain will take input variables, pass those to a prompt template to create a prompt, pass the prompt to a language model, and then pass the output through an (optional) output parser. This is a convenient way to bundle up a modular piece of logic. Let's see it in action!  from typing import List  from langchain.chat_models import ChatOpenAI from langchain.prompts import ChatPromptTemplate from langchain.schema import BaseOutputParser  class CommaSeparatedListOutputParser(BaseOutputParser[List[str]]):     """"""Parse the output of an LLM call to a comma-separated list.""""""       def parse(self, text: str) -> List[str]:         """"""Parse the output of an LLM call.""""""         return text.strip().split("", "")  template = """"""You are a helpful assistant who generates comma separated lists. A user will pass in a category, and you should generate 5 objects in that category in a comma separated list. ONLY return a comma separated list, and nothing more."""""" human_template = ""{text}""  chat_prompt = ChatPromptTemplate.from_messages([     (""system"", template),     (""human"", human_template), ]) chain = chat_prompt | ChatOpenAI() | CommaSeparatedListOutputParser() chain.invoke({""text"": ""colors""}) # >> ['red', 'blue', 'green', 'yellow', 'orange']  Note that we are using the | syntax to join these components together. This | syntax is powered by the LangChain Expression Language (LCEL) and relies on the universal Runnable interface that all of these objects implement. To learn more about LCEL, read the documentation here.  Tracing with LangSmith​ Assuming we've set our environment variables as shown in the beginning, all of the model and chain calls we've been making will have been automatically logged to LangSmith. Once there, we can use LangSmith to debug and annotate our application traces, then turn them into datasets for evaluating future iterations of the application.  Check out what the trace for the above chain would look like: https://smith.langchain.com/public/09370280-4330-4eb4-a7e8-c91817f6aa13/r  For more on LangSmith head here.  Serving with LangServe​ Now that we've built an application, we need to serve it. That's where LangServe comes in. LangServe helps developers deploy LCEL chains as a REST API. The library is integrated with FastAPI and uses pydantic for data validation.  Server​ To create a server for our application we'll make a serve.py file with three things:  The definition of our chain (same as above) Our FastAPI app A definition of a route from which to serve the chain, which is done with langserve.add_routes #!/usr/bin/env p"

Debugging | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/debugging,langchain_docs,"Main:  On this page #Debugging If you're building with LLMs, at some point something will break, and you'll need to debug. A model call will fail, or the model output will be misformatted, or there will be some nested model calls and it won't be clear where along the way an incorrect output was created.  Here are a few different tools and functionalities to aid in debugging.  ##Tracing[​](#tracing) Platforms with tracing capabilities like [LangSmith](/docs/langsmith/) and [WandB](/docs/integrations/providers/wandb_tracing) are the most comprehensive solutions for debugging. These platforms make it easy to not only log and visualize LLM apps, but also to actively debug, test and refine them.  For anyone building production-grade LLM applications, we highly recommend using a platform like this.    ##set_debug and set_verbose[​](#set_debug-and-set_verbose) If you're prototyping in Jupyter Notebooks or running Python scripts, it can be helpful to print out the intermediate steps of a Chain run.  There are a number of ways to enable printing at varying degrees of verbosity.  Let's suppose we have a simple agent, and want to visualize the actions it takes and tool outputs it receives. Without any debugging, here's what we see:  from langchain.agents import AgentType, initialize_agent, load_tools from langchain.chat_models import ChatOpenAI  llm = ChatOpenAI(model_name=""gpt-4"", temperature=0) tools = load_tools([""ddg-search"", ""llm-math""], llm=llm) agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION)  agent.run(""Who directed the 2023 film Oppenheimer and what is their age? What is their age in days (assume 365 days per year)?"")      'The director of the 2023 film Oppenheimer is Christopher Nolan and he is approximately 19345 days old in 2023.'  ###set_debug(True)[​](#set_debugtrue) Setting the global debug flag will cause all LangChain components with callback support (chains, models, agents, tools, retrievers) to print the inputs they receive and outputs they generate. This is the most verbose setting and will fully log raw inputs and outputs.  from langchain.globals import set_debug  set_debug(True)  agent.run(""Who directed the 2023 film Oppenheimer and what is their age? What is their age in days (assume 365 days per year)?"")  Console output ###set_verbose(True)[​](#set_verbosetrue) Setting the verbose flag will print out inputs and outputs in a slightly more readable format and will skip logging certain raw outputs (like the token usage stats for an LLM call) so that you can focus on application logic.  from langchain.globals import set_verbose  set_verbose(True)  agent.run(""Who directed the 2023 film Oppenheimer and what is their age? What is their age in days (assume 365 days per year)?"")  Console output ###Chain(..., verbose=True)[​](#chain-verbosetrue) You can also scope verbosity down to a single object, in which case only the inputs and outputs to that object are printed (along with any additional callbacks calls made specifically by that object).  # Passing verbose=True to initialize_agent will pass that along to the AgentExecutor (which is a Chain). agent = initialize_agent(     tools,      llm,      agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,     verbose=True, )  agent.run(""Who directed the 2023 film Oppenheimer and what is their age? What is their age in days (assume 365 days per year)?"")  Console output ##Other callbacks[​](#other-callbacks) Callbacks are what we use to execute any functionality within a component outside the primary component logic. All of the above solutions use Callbacks under the hood to log intermediate steps of components. There are a number of Callbacks relevant for debugging that come with LangChain out of the box, like the [FileCallbackHandler](/docs/modules/callbacks/how_to/filecallbackhandler). You can also implement your own callbacks to execute custom functionality.  See here for more info on [Callbacks](/docs/modules/callbacks/), how to use them, and customize them.  "
Deployment | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/deployments/,langchain_docs,"Main:  On this page #Deployment In today's fast-paced technological landscape, the use of Large Language Models (LLMs) is rapidly expanding. As a result, it is crucial for developers to understand how to effectively deploy these models in production environments. LLM interfaces typically fall into two categories:  - Case 1: Utilizing External LLM Providers (OpenAI, Anthropic, etc.) In this scenario, most of the computational burden is handled by the LLM providers, while LangChain simplifies the implementation of business logic around these services. This approach includes features such as prompt templating, chat message generation, caching, vector embedding database creation, preprocessing, etc.  - Case 2: Self-hosted Open-Source Models Alternatively, developers can opt to use smaller, yet comparably capable, self-hosted open-source LLM models. This approach can significantly decrease costs, latency, and privacy concerns associated with transferring data to external LLM providers.  Regardless of the framework that forms the backbone of your product, deploying LLM applications comes with its own set of challenges. It's vital to understand the trade-offs and key considerations when evaluating serving frameworks.  ##Outline[​](#outline) This guide aims to provide a comprehensive overview of the requirements for deploying LLMs in a production setting, focusing on:  - Designing a Robust LLM Application Service - Maintaining Cost-Efficiency - Ensuring Rapid Iteration Understanding these components is crucial when assessing serving systems. LangChain integrates with several open-source projects designed to tackle these issues, providing a robust framework for productionizing your LLM applications. Some notable frameworks include:  - [Ray Serve](/docs/ecosystem/integrations/ray_serve) - [BentoML](https://github.com/bentoml/BentoML) - [OpenLLM](/docs/ecosystem/integrations/openllm) - [Modal](/docs/ecosystem/integrations/modal) - [Jina](/docs/ecosystem/integrations/jina#deployment) These links will provide further information on each ecosystem, assisting you in finding the best fit for your LLM deployment needs.  ##Designing a Robust LLM Application Service[​](#designing-a-robust-llm-application-service) When deploying an LLM service in production, it's imperative to provide a seamless user experience free from outages. Achieving 24/7 service availability involves creating and maintaining several sub-systems surrounding your application.  ###Monitoring[​](#monitoring) Monitoring forms an integral part of any system running in a production environment. In the context of LLMs, it is essential to monitor both performance and quality metrics.  Performance Metrics: These metrics provide insights into the efficiency and capacity of your model. Here are some key examples:  - Query per second (QPS): This measures the number of queries your model processes in a second, offering insights into its utilization. - Latency: This metric quantifies the delay from when your client sends a request to when they receive a response. - Tokens Per Second (TPS): This represents the number of tokens your model can generate in a second. Quality Metrics: These metrics are typically customized according to the business use-case. For instance, how does the output of your system compare to a baseline, such as a previous version? Although these metrics can be calculated offline, you need to log the necessary data to use them later.  ###Fault tolerance[​](#fault-tolerance) Your application may encounter errors such as exceptions in your model inference or business logic code, causing failures and disrupting traffic. Other potential issues could arise from the machine running your application, such as unexpected hardware breakdowns or loss of spot-instances during high-demand periods. One way to mitigate these risks is by increasing redundancy through replica scaling and implementing recovery mechanisms for failed replicas. However, model replicas aren't the only potential points of failure. It's essential to build resilience against various failures that could occur at any point in your stack.  ###Zero down time upgrade[​](#zero-down-time-upgrade) System upgrades are often necessary but can result in service disruptions if not handled correctly. One way to prevent downtime during upgrades is by implementing a smooth transition process from the old version to the new one. Ideally, the new version of your LLM service is deployed, and traffic gradually shifts from the old to the new version, maintaining a constant QPS throughout the process.  ###Load balancing[​](#load-balancing) Load balancing, in simple terms, is a technique to distribute work evenly across multiple computers, servers, or other resources to optimize the utilization of the system, maximize throughput, minimize response time, and avoid overload of any single resource. Think of it as a traffic officer directing cars (requests) to different roads (servers) so that no single road becomes too congested.  There are several strategies for load balancing. For example, one common method is the Round Robin strategy, where each request is sent to the next server in line, cycling back to the first when all servers have received a request. This works well when all servers are equally capable. However, if some servers are more powerful than others, you might use a Weighted Round Robin or Least Connections strategy, where more requests are sent to the more powerful servers, or to those currently handling the fewest active requests. Let's imagine you're running a LLM chain. If your application becomes popular, you could have hundreds or even thousands of users asking questions at the same time. If one server gets too busy (high load), the load balancer would direct new requests to another server that is less busy. This way, all your users get a timely response and the system remains stable.  ##Maintaining Cost-Efficiency and Scalability[​](#maintaining-cost-efficiency-and-scalabi"
Deployment | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/deployments/,langchain_docs,"lity) Deploying LLM services can be costly, especially when you're handling a large volume of user interactions. Charges by LLM providers are usually based on tokens used, making a chat system inference on these models potentially expensive. However, several strategies can help manage these costs without compromising the quality of the service.  ###Self-hosting models[​](#self-hosting-models) Several smaller and open-source LLMs are emerging to tackle the issue of reliance on LLM providers. Self-hosting allows you to maintain similar quality to LLM provider models while managing costs. The challenge lies in building a reliable, high-performing LLM serving system on your own machines.  ###Resource Management and Auto-Scaling[​](#resource-management-and-auto-scaling) Computational logic within your application requires precise resource allocation. For instance, if part of your traffic is served by an OpenAI endpoint and another part by a self-hosted model, it's crucial to allocate suitable resources for each. Auto-scaling—adjusting resource allocation based on traffic—can significantly impact the cost of running your application. This strategy requires a balance between cost and responsiveness, ensuring neither resource over-provisioning nor compromised application responsiveness.  ###Utilizing Spot Instances[​](#utilizing-spot-instances) On platforms like AWS, spot instances offer substantial cost savings, typically priced at about a third of on-demand instances. The trade-off is a higher crash rate, necessitating a robust fault-tolerance mechanism for effective use.  ###Independent Scaling[​](#independent-scaling) When self-hosting your models, you should consider independent scaling. For example, if you have two translation models, one fine-tuned for French and another for Spanish, incoming requests might necessitate different scaling requirements for each.  ###Batching requests[​](#batching-requests) In the context of Large Language Models, batching requests can enhance efficiency by better utilizing your GPU resources. GPUs are inherently parallel processors, designed to handle multiple tasks simultaneously. If you send individual requests to the model, the GPU might not be fully utilized as it's only working on a single task at a time. On the other hand, by batching requests together, you're allowing the GPU to work on multiple tasks at once, maximizing its utilization and improving inference speed. This not only leads to cost savings but can also improve the overall latency of your LLM service.  In summary, managing costs while scaling your LLM services requires a strategic approach. Utilizing self-hosting models, managing resources effectively, employing auto-scaling, using spot instances, independently scaling models, and batching requests are key strategies to consider. Open-source libraries such as Ray Serve and BentoML are designed to deal with these complexities.  ##Ensuring Rapid Iteration[​](#ensuring-rapid-iteration) The LLM landscape is evolving at an unprecedented pace, with new libraries and model architectures being introduced constantly. Consequently, it's crucial to avoid tying yourself to a solution specific to one particular framework. This is especially relevant in serving, where changes to your infrastructure can be time-consuming, expensive, and risky. Strive for infrastructure that is not locked into any specific machine learning library or framework, but instead offers a general-purpose, scalable serving layer. Here are some aspects where flexibility plays a key role:  ###Model composition[​](#model-composition) Deploying systems like LangChain demands the ability to piece together different models and connect them via logic. Take the example of building a natural language input SQL query engine. Querying an LLM and obtaining the SQL command is only part of the system. You need to extract metadata from the connected database, construct a prompt for the LLM, run the SQL query on an engine, collect and feed back the response to the LLM as the query runs, and present the results to the user. This demonstrates the need to seamlessly integrate various complex components built in Python into a dynamic chain of logical blocks that can be served together.  ##Cloud providers[​](#cloud-providers) Many hosted solutions are restricted to a single cloud provider, which can limit your options in today's multi-cloud world. Depending on where your other infrastructure components are built, you might prefer to stick with your chosen cloud provider.  ##Infrastructure as Code (IaC)[​](#infrastructure-as-code-iac) Rapid iteration also involves the ability to recreate your infrastructure quickly and reliably. This is where Infrastructure as Code (IaC) tools like Terraform, CloudFormation, or Kubernetes YAML files come into play. They allow you to define your infrastructure in code files, which can be version controlled and quickly deployed, enabling faster and more reliable iterations.  ##CI/CD[​](#cicd) In a fast-paced environment, implementing CI/CD pipelines can significantly speed up the iteration process. They help automate the testing and deployment of your LLM applications, reducing the risk of errors and enabling faster feedback and iteration.  "

Evaluation | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/evaluation/,langchain_docs,"Main:  On this page #Evaluation Building applications with language models involves many moving parts. One of the most critical components is ensuring that the outcomes produced by your models are reliable and useful across a broad array of inputs, and that they work well with your application's other software components. Ensuring reliability usually boils down to some combination of application design, testing & evaluation, and runtime checks.  The guides in this section review the APIs and functionality LangChain provides to help you better evaluate your applications. Evaluation and testing are both critical when thinking about deploying LLM applications, since production environments require repeatable and useful outcomes.  LangChain offers various types of evaluators to help you measure performance and integrity on diverse data, and we hope to encourage the community to create and share other useful evaluators so everyone can improve. These docs will introduce the evaluator types, how to use them, and provide some examples of their use in real-world scenarios.  Each evaluator type in LangChain comes with ready-to-use implementations and an extensible API that allows for customization according to your unique requirements. Here are some of the types of evaluators we offer:  - [String Evaluators](/docs/guides/evaluation/string/): These evaluators assess the predicted string for a given input, usually comparing it against a reference string. - [Trajectory Evaluators](/docs/guides/evaluation/trajectory/): These are used to evaluate the entire trajectory of agent actions. - [Comparison Evaluators](/docs/guides/evaluation/comparison/): These evaluators are designed to compare predictions from two runs on a common input. These evaluators can be used across various scenarios and can be applied to different chain and LLM implementations in the LangChain library.  We also are working to share guides and cookbooks that demonstrate how to use these evaluators in real-world scenarios, such as:  - [Chain Comparisons](/docs/guides/evaluation/examples/comparisons): This example uses a comparison evaluator to predict the preferred output. It reviews ways to measure confidence intervals to select statistically significant differences in aggregate preference scores across different models or prompts. ##Reference Docs[​](#reference-docs) For detailed information on the available evaluators, including how to instantiate, configure, and customize them, check out the [reference documentation](https://api.python.langchain.com/en/latest/api_reference.html#module-langchain.evaluation) directly.

Comparison Evaluators | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/evaluation/comparison/,langchain_docs,"Main:  #Comparison Evaluators Comparison evaluators in LangChain help measure two different chains or LLM outputs. These evaluators are helpful for comparative analyses, such as A/B testing between two language models, or comparing different versions of the same model. They can also be useful for things like generating preference scores for ai-assisted reinforcement learning.  These evaluators inherit from the PairwiseStringEvaluator class, providing a comparison interface for two strings - typically, the outputs from two different prompts or models, or two versions of the same model. In essence, a comparison evaluator performs an evaluation on a pair of strings and returns a dictionary containing the evaluation score and other relevant details.  To create a custom comparison evaluator, inherit from the PairwiseStringEvaluator class and overwrite the _evaluate_string_pairs method. If you require asynchronous evaluation, also overwrite the _aevaluate_string_pairs method.  Here's a summary of the key methods and properties of a comparison evaluator:  - evaluate_string_pairs: Evaluate the output string pairs. This function should be overwritten when creating custom evaluators. - aevaluate_string_pairs: Asynchronously evaluate the output string pairs. This function should be overwritten for asynchronous evaluation. - requires_input: This property indicates whether this evaluator requires an input string. - requires_reference: This property specifies whether this evaluator requires a reference label. LANGSMITH SUPPORT The [run_on_dataset](https://api.python.langchain.com/en/latest/api_reference.html#module-langchain.smith) evaluation method is designed to evaluate only a single model at a time, and thus, doesn't support these evaluators.

Note: This returns a distance score, meaning that the lower the number, the more similar the outputs are, according to their embedded representation.  Check out the reference docs for the [PairwiseEmbeddingDistanceEvalChain](https://api.python.langchain.com/en/latest/evaluation/langchain.evaluation.embedding_distance.base.PairwiseEmbeddingDistanceEvalChain.html#langchain.evaluation.embedding_distance.base.PairwiseEmbeddingDistanceEvalChain) for more info.  from langchain.evaluation import load_evaluator  evaluator = load_evaluator(""pairwise_embedding_distance"")  evaluator.evaluate_string_pairs(     prediction=""Seattle is hot in June"", prediction_b=""Seattle is cool in June."" )      {'score': 0.0966466944859925}  evaluator.evaluate_string_pairs(     prediction=""Seattle is warm in June"", prediction_b=""Seattle is cool in June."" )      {'score': 0.03761174337464557}  ##Select the Distance Metric[​](#select-the-distance-metric) By default, the evaluator uses cosine distance.

Response A is correct but lacks depth as it does not explain what the operation of addition entails. \n\nFinal Decision: [[B]]',      'value': 'B',      'score': 0}  ##Defining the Criteria[​](#defining-the-criteria) By default, the LLM is instructed to select the 'preferred' response based on helpfulness, relevance, correctness, and depth of thought. You can customize the criteria by passing in a criteria argument, where the criteria could take any of the following forms:  - [Criteria](https://api.python.langchain.com/en/latest/evaluation/langchain.evaluation.criteria.eval_chain.Criteria.html#langchain.evaluation.criteria.eval_chain.Criteria) enum or its string value - to use one of the default criteria and their descriptions - [Constitutional principal](https://api.python.langchain.com/en/latest/chains/langchain.chains.constitutional_ai.models.ConstitutionalPrinciple.html#langchain.chains.constitutional_ai.models.ConstitutionalPrinciple) - use one any of the constitutional principles defined in langchain - Dictionary: a list of custom criteria, where the key is the name of the criteria, and the value is the description. - A list of criteria or constitutional principles - to combine multiple criteria in one. Below is an example for determining preferred writing responses based on a custom style.  custom_criteria = {     ""simplicity"": ""Is the language straightforward and unpretentious?"",     ""clarity"": ""Are the sentences clear and easy to understand?"",     ""precision"": ""Is the writing precise, with no unnecessary words or details?"",     ""truthfulness"": ""Does the writing feel honest and sincere?"",     ""subtext"": ""Does the writing suggest deeper meanings or themes?"", } evaluator = load_evaluator(""pairwise_string"", criteria=custom_criteria)  evaluator.evaluate_string_pairs(     prediction=""Every cheerful household shares a similar rhythm of joy; but sorrow, in each household, plays a unique, haunting melody."",     prediction_b=""Where one finds a symphony of joy, every domicile of happiness resounds in harmonious,""     "" identical notes; ye"

The language is more pretentious, with words like ""domicile,"" ""resounds,"" ""abode,"" ""dissonant,"" and ""elegy."" While it conveys a similar message to Response A, it does so in a more convoluted way.

In contrast, Response A states ""there are three dogs"", which is incorrect according to the reference answer. \n\nIn terms of helpfulness, Response B gives the precise number while Response A provides an inaccurate guess. For relevance, both refer to dogs in the park from the question. However, Response B is more correct and factual based on the reference answer.

How do you know which will generate ""better"" results?  One automated way to predict the preferred configuration is to use a PairwiseStringEvaluator like the PairwiseStringEvalChain[1]. This chain prompts an LLM to select which output is preferred, given a specific input.  For this evaluation, we will need 3 things:  An evaluator A dataset of inputs 2 (or more) LLMs, Chains, or Agents to compare Then we will aggregate the results to determine the preferred model.  Step 1. Create the Evaluator​ In this example, you will use gpt-4 to select which output is preferred.  from langchain.evaluation import load_evaluator  eval_chain = load_evaluator(""pairwise_string"")  Step 2. Select Dataset​ If you already have real usage data for your LLM, you can use a representative sample. More examples provide more reliable results. We will use some example queries someone might have about how to use langchain here.  from langchain.evaluation.loading import load_dataset  dataset = load_dataset(""langchain-howto-queries"")      Found cached dataset parquet (/Users/wfh/.cache/huggingface/datasets/LangChainDatasets___parquet/LangChainDatasets--langchain-howto-queries-bbb748bbee7e77aa/0.0.0/14a00e99c0d15a23649d0db8944380ac81082d4b021f398733dd84f3a6c569a7)          0%|          | 0/1 [00:00<?, ?it/s]  Step 3. Define Models to Compare​ We will be comparing two agents in this case.  from langchain.agents import AgentType, Tool, initialize_agent from langchain.chat_models import ChatOpenAI from langchain.utilities import SerpAPIWrapper  # Initialize the language model # You can add your own OpenAI API key by adding openai_api_key=""<your_api_key>"" llm = ChatOpenAI(temperature=0, model=""gpt-3.5-turbo-0613"")  # Initialize the SerpAPIWrapper for search functionality # Replace <your_api_key> in openai_api_key=""<your_api_key>"" with your actual SerpAPI key. search = SerpAPIWrapper()  # Define a list of tools offered by the agent tools = [     Tool(         name=""Search"",         func=search.run,         coroutine=search.arun,         description=""Useful when you need to answer questions about current events. You should ask targeted questions."",     ), ]  functions_agent = initialize_agent(     tools, llm, agent=AgentType.OPENAI_MULTI_FUNCTIONS, verbose=False ) conversations_agent = initialize_agent(     tools, llm, agent=AgentType.CHAT_ZERO_SHOT_REACT_DESCRIPTION, verbose=False )  Step 4. Generate Responses​ We will generate outputs for each of the models before evaluating them.  import asyncio  from tqdm.notebook import tqdm  results = [] agents = [functions_agent, conversations_agent] concurrency_level = 6  # How many concurrent agents to run. May need to decrease if OpenAI is rate limiting.  # We will only run the first 20 examples of this dataset to speed things up # This will lead to larger confidence intervals downstream. batch = [] for example in tqdm(dataset[:20]):     batch.extend([agent.acall(example[""inputs""]) for agent in agents])     if len(batch) >= concurrency_level:         batch_results = await asyncio.gather(*batch, return_exceptions=True)         results.extend(list(zip(*[iter(batch_results)] * 2)))         batch = [] if batch:     batch_results = await asyncio.gather(*batch, return_exceptions=True)     results.extend(list(zip(*[iter(batch_results)] * 2)))        0%|          | 0/20 [00:00<?, ?it/s]  Step 5. Evaluate Pairs​ Now it's time to evaluate the results. For each agent response, run the evaluation chain to select which output is preferred (or return a tie).  Randomly select the input order to reduce the likelihood that one model will be preferred just because it is presented first.  import random   def predict_preferences(dataset, results) -> list:     preferences = []      for example, (res_a, res_b) in zip(dataset, results):         input_ = example[""inputs""]         # Flip a coin to reduce persistent position bias         if random.random() < 0.5:             pred_a, pred_b = res_a, res_b             a, b = ""a"", ""b""         else:             pred_a, pred_b = res_b, res_a             a, b = ""b"", ""a""         eval_res = eval_chain.evaluate_string_pairs(             prediction=pred_a[""output""] if isinstance(pred_a, dict) else str(pred_a),             prediction_b=pred_b[""output""] if isinstance(pred_b, dict) else str(pred_b),             input=input_,         )         if eval_res[""value""] == ""A"":             preferences.append(a)         elif eval_res[""value""] == ""B"":             preferences.append(b)         else:             preferences.append(None)  # No preference     return preferences  preferences = predict_preferences(dataset, results)  Print out the ratio of preferences.  from collections import Counter  name_map = {     ""a"": ""OpenAI Functions Agent"",     ""b"": ""Structured Chat Agent"", } counts = Counter(preferences) pref_ratios = {k: v / len(preferences) for k, v in counts.items()} for k, v in pref_ratios.items():     print(f""{name_map.get(k)}: {v:.2%}"")      OpenAI Functions Agent: 95.00%     None: 5.00%  Estimate Confidence Intervals​ The results seem pretty clear, but if you want to have a better sense of how confident we are, that model ""A"" (the OpenAI Functions Agent) is the preferred model, we can calculate confidence intervals.  Below, use the Wilson score to estimate the confidence interval.  from math import sqrt   def wilson_score_interval(     preferences: list, which: str = ""a"", z: float = 1.96 ) -> tuple:     """"""Estimate the confidence interval using the Wilson score.

String Evaluators | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/evaluation/string/,langchain_docs,"Main:  #String Evaluators A string evaluator is a component within LangChain designed to assess the performance of a language model by comparing its generated outputs (predictions) to a reference string or an input. This comparison is a crucial step in the evaluation of language models, providing a measure of the accuracy or quality of the generated text.  In practice, string evaluators are typically used to evaluate a predicted string against a given input, such as a question or a prompt. Often, a reference label or context string is provided to define what a correct or ideal response would look like. These evaluators can be customized to tailor the evaluation process to fit your application's specific requirements.  To create a custom string evaluator, inherit from the StringEvaluator class and implement the _evaluate_strings method. If you require asynchronous support, also implement the _aevaluate_strings method.  Here's a summary of the key attributes and methods associated with a string evaluator:  - evaluation_name: Specifies the name of the evaluation. - requires_input: Boolean attribute that indicates whether the evaluator requires an input string. If True, the evaluator will raise an error when the input isn't provided. If False, a warning will be logged if an input is provided, indicating that it will not be considered in the evaluation. - requires_reference: Boolean attribute specifying whether the evaluator requires a reference label. If True, the evaluator will raise an error when the reference isn't provided. If False, a warning will be logged if a reference is provided, indicating that it will not be considered in the evaluation. String evaluators also implement the following methods:  - aevaluate_strings: Asynchronously evaluates the output of the Chain or Language Model, with support for optional input and label. - evaluate_strings: Synchronously evaluates the output of the Chain or Language Model, with support for optional input and label. The following sections provide detailed information on available string evaluator implementations as well as how to create a custom string evaluator.

Criteria Evaluation | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/evaluation/string/criteria_eval_chain,langchain_docs,"Main:  On this page #Criteria Evaluation [](https://colab.research.google.com/github/langchain-ai/langchain/blob/master/docs/docs/guides/evaluation/string/criteria_eval_chain.ipynb)  In scenarios where you wish to assess a model's output using a specific rubric or criteria set, the criteria evaluator proves to be a handy tool. It allows you to verify if an LLM or Chain's output complies with a defined set of criteria.  To understand its functionality and configurability in depth, refer to the reference documentation of the [CriteriaEvalChain](https://api.python.langchain.com/en/latest/evaluation/langchain.evaluation.criteria.eval_chain.CriteriaEvalChain.html#langchain.evaluation.criteria.eval_chain.CriteriaEvalChain) class.  ###Usage without references[​](#usage-without-references) In this example, you will use the CriteriaEvalChain to check whether an output is concise. First, create the evaluation chain to predict whether outputs are ""concise"".  from langchain.evaluation import load_evaluator  evaluator = load_evaluator(""criteria"", criteria=""conciseness"")  # This is equivalent to loading using the enum from langchain.evaluation import EvaluatorType  evaluator = load_evaluator(EvaluatorType.CRITERIA, criteria=""conciseness"")  eval_result = evaluator.evaluate_strings(     prediction=""What's 2+2? That's an elementary question. The answer you're looking for is that two and two is four."",     input=""What's 2+2?"", ) print(eval_result)      {'reasoning': 'The criterion is conciseness, which means the submission should be brief and to the point. \n\nLooking at the submission, the answer to the question ""What\'s 2+2?"" is indeed ""four"". However, the respondent has added extra information, stating ""That\'s an elementary question."" This statement does not contribute to answering the question and therefore makes the response less concise.\n\nTherefore, the submission does not meet the criterion of conciseness.\n\nN', 'value': 'N', 'score': 0}  ####Output Format[​](#output-format) All string evaluators expose an [evaluate_strings](https://api.python.langchain.com/en/latest/evaluation/langchain.evaluation.criteria.eval_chain.CriteriaEvalChain.html?highlight=evaluate_strings#langchain.evaluation.criteria.eval_chain.CriteriaEvalChain.evaluate_strings) (or async [aevaluate_strings](https://api.python.langchain.com/en/latest/evaluation/langchain.evaluation.criteria.eval_chain.CriteriaEvalChain.html?highlight=evaluate_strings#langchain.evaluation.criteria.eval_chain.CriteriaEvalChain.aevaluate_strings)) method, which accepts:  - input (str) – The input to the agent. - prediction (str) – The predicted response. The criteria evaluators return a dictionary with the following values:  - score: Binary integer 0 to 1, where 1 would mean that the output is compliant with the criteria, and 0 otherwise - value: A ""Y"" or ""N"" corresponding to the score - reasoning: String ""chain of thought reasoning"" from the LLM generated prior to creating the score ##Using Reference Labels[​](#using-reference-labels) Some criteria (such as correctness) require reference labels to work correctly. To do this, initialize the labeled_criteria evaluator and call the evaluator with a reference string.  evaluator = load_evaluator(""labeled_criteria"", criteria=""correctness"")  # We can even override the model's learned knowledge using ground truth labels eval_result = evaluator.evaluate_strings(     input=""What is the capital of the US?"",     prediction=""Topeka, KS"",     reference=""The capital of the US is Topeka, KS, where it permanently moved from Washington D.C. on May 16, 2023"", ) print(f'With ground truth: {eval_result[""score""]}')      With ground truth: 1  Default Criteria  Most of the time, you'll want to define your own custom criteria (see below), but we also provide some common criteria you can load with a single string. Here's a list of pre-implemented criteria. Note that in the absence of labels, the LLM merely predicts what it thinks the best answer is and is not grounded in actual law or context.  from langchain.evaluation import Criteria  # For a list of other default supported criteria, try calling `supported_default_criteria` list(Criteria)      [<Criteria.CONCISENESS: 'conciseness'>,      <Criteria.RELEVANCE: 'relevance'>,      <Criteria.CORRECTNESS: 'correctness'>,      <Criteria.COHERENCE: 'coherence'>,      <Criteria.HARMFULNESS: 'harmfulness'>,      <Criteria.MALICIOUSNESS: 'maliciousness'>,      <Criteria.HELPFULNESS: 'helpfulness'>,      <Criteria.CONTROVERSIALITY: 'controversiality'>,      <Criteria.MISOGYNY: 'misogyny'>,      <Criteria.CRIMINALITY: 'criminality'>,      <Criteria.INSENSITIVITY: 'insensitivity'>]  ##Custom Criteria[​](#custom-criteria) To evaluate outputs against your own custom criteria, or to be more explicit the definition of any of the default criteria, pass in a dictionary of ""criterion_name"": ""criterion_description""  Note: it's recommended that you create a single evaluator per criterion. This way, separate feedback can be provided for each aspect. Additionally, if you provide antagonistic criteria, the evaluator won't be very useful, as it will be configured to predict compliance for ALL of the criteria provided.  custom_criterion = {     ""numeric"": ""Does the output contain numeric or mathematical information?"" }  eval_chain = load_evaluator(     EvaluatorType.CRITERIA,     criteria=custom_criterion, ) query = ""Tell me a joke"" prediction = ""I ate some square pie but I don't know the square of pi."" eval_result = eval_chain.evaluate_strings(prediction=prediction, input=query) print(eval_result)  # If you wanted to specify multiple criteria.

This can be used alongside approximate/fuzzy matching criteria for very basic unit testing.  This can be accessed using the string_distance evaluator, which uses distance metric's from the [rapidfuzz](https://github.com/maxbachmann/RapidFuzz) library.

Trajectory Evaluators | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/evaluation/trajectory/,langchain_docs,"Main:  #Trajectory Evaluators Trajectory Evaluators in LangChain provide a more holistic approach to evaluating an agent. These evaluators assess the full sequence of actions taken by an agent and their corresponding responses, which we refer to as the ""trajectory"". This allows you to better measure an agent's effectiveness and capabilities.  A Trajectory Evaluator implements the AgentTrajectoryEvaluator interface, which requires two main methods:  - evaluate_agent_trajectory: This method synchronously evaluates an agent's trajectory. - aevaluate_agent_trajectory: This asynchronous counterpart allows evaluations to be run in parallel for efficiency. Both methods accept three main parameters:  - input: The initial input given to the agent. - prediction: The final predicted response from the agent. - agent_trajectory: The intermediate steps taken by the agent, given as a list of tuples. These methods return a dictionary. It is recommended that custom implementations return a score (a float indicating the effectiveness of the agent) and reasoning (a string explaining the reasoning behind the score).  You can capture an agent's trajectory by initializing the agent with the return_intermediate_steps=True parameter. This lets you collect all intermediate steps without relying on special callbacks.  For a deeper dive into the implementation and use of Trajectory Evaluators, refer to the sections below.

We recommend using multiple evaluation techniques appropriate to your use case. One way to evaluate an agent is to look at the whole trajectory of actions taken along with their responses.  Evaluators that do this can implement the AgentTrajectoryEvaluator interface. This walkthrough will show how to use the trajectory evaluator to grade an OpenAI functions agent.

Fallbacks | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/fallbacks,langchain_docs,"Main:  On this page #Fallbacks When working with language models, you may often encounter issues from the underlying APIs, whether these be rate limiting or downtime. Therefore, as you go to move your LLM applications into production it becomes more and more important to safeguard against these. That's why we've introduced the concept of fallbacks.  A fallback is an alternative plan that may be used in an emergency.  Crucially, fallbacks can be applied not only on the LLM level but on the whole runnable level. This is important because often times different models require different prompts. So if your call to OpenAI fails, you don't just want to send the same prompt to Anthropic - you probably want to use a different prompt template and send a different version there.  ##Fallback for LLM API Errors[​](#fallback-for-llm-api-errors) This is maybe the most common use case for fallbacks. A request to an LLM API can fail for a variety of reasons - the API could be down, you could have hit rate limits, any number of things. Therefore, using fallbacks can help protect against these types of things.  IMPORTANT: By default, a lot of the LLM wrappers catch errors and retry. You will most likely want to turn those off when working with fallbacks. Otherwise the first wrapper will keep on retrying and not failing.  from langchain.chat_models import ChatAnthropic, ChatOpenAI  First, let's mock out what happens if we hit a RateLimitError from OpenAI  from unittest.mock import patch  from openai.error import RateLimitError  # Note that we set max_retries = 0 to avoid retrying on RateLimits, etc openai_llm = ChatOpenAI(max_retries=0) anthropic_llm = ChatAnthropic() llm = openai_llm.with_fallbacks([anthropic_llm])  # Let's use just the OpenAI LLm first, to show that we run into an error with patch(""openai.ChatCompletion.create"", side_effect=RateLimitError()):     try:         print(openai_llm.invoke(""Why did the chicken cross the road?""))     except:         print(""Hit error"")      Hit error  # Now let's try with fallbacks to Anthropic with patch(""openai.ChatCompletion.create"", side_effect=RateLimitError()):     try:         print(llm.invoke(""Why did the chicken cross the road?""))     except:         print(""Hit error"")      content=' I don\'t actually know why the chicken crossed the road, but here are some possible humorous answers:\n\n- To get to the other side!\n\n- It was too chicken to just stand there. \n\n- It wanted a change of scenery.\n\n- It wanted to show the possum it could be done.\n\n- It was on its way to a poultry farmers\' convention.\n\nThe joke plays on the double meaning of ""the other side"" - literally crossing the road to the other side, or the ""other side"" meaning the afterlife.

Let me know if you have any other animal jokes I can try to decipher."" additional_kwargs={} example=False  ##Fallback for Sequences[​](#fallback-for-sequences) We can also create fallbacks for sequences, that are sequences themselves. Here we do that with two different models: ChatOpenAI and then normal OpenAI (which does not use a chat model). Because OpenAI is NOT a chat model, you likely want a different prompt.  # First let's create a chain with a ChatModel # We add in a string output parser here so the outputs between the two are the same type from langchain.schema.output_parser import StrOutputParser  chat_prompt = ChatPromptTemplate.from_messages(     [         (             ""system"",             ""You're a nice assistant who always includes a compliment in your response"",         ),         (""human"", ""Why did the {animal} cross the road""),     ] ) # Here we're going to use a bad model name to easily create a chain that will error chat_model = ChatOpenAI(model_name=""gpt-fake"") bad_chain = chat_prompt | chat_model | StrOutputParser()  # Now lets create a chain with the normal OpenAI model from langchain.llms import OpenAI from langchain.prompts import PromptTemplate  prompt_template = """"""Instructions: You should always include a compliment in your response.

Run LLMs locally | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/local_llms,langchain_docs,"Main:  On this page #Run LLMs locally ##Use case[​](#use-case) The popularity of projects like [PrivateGPT](https://github.com/imartinez/privateGPT), [llama.cpp](https://github.com/ggerganov/llama.cpp), and [GPT4All](https://github.com/nomic-ai/gpt4all) underscore the demand to run LLMs locally (on your own device).  This has at least two important benefits:  - Privacy: Your data is not sent to a third party, and it is not subject to the terms of service of a commercial service - Cost: There is no inference fee, which is important for token-intensive applications (e.g., [long-running simulations](https://twitter.com/RLanceMartin/status/1691097659262820352?s=20), summarization) ##Overview[​](#overview) Running an LLM locally requires a few things:  - Open-source LLM: An open-source LLM that can be freely modified and shared - Inference: Ability to run this LLM on your device w/ acceptable latency ###Open-source LLMs[​](#open-source-llms) Users can now gain access to a rapidly growing set of [open-source LLMs](https://cameronrwolfe.substack.com/p/the-history-of-open-source-llms-better).  These LLMs can be assessed across at least two dimensions (see figure):  - Base model: What is the base-model and how was it trained? - Fine-tuning approach: Was the base-model fine-tuned and, if so, what [set of instructions](https://cameronrwolfe.substack.com/p/beyond-llama-the-power-of-open-llms#%C2%A7alpaca-an-instruction-following-llama-model) was used?   The relative performance of these models can be assessed using several leaderboards, including:  - [LmSys](https://chat.lmsys.org/?arena) - [GPT4All](https://gpt4all.io/index.html) - [HuggingFace](https://huggingface.co/spaces/lmsys/chatbot-arena-leaderboard) ###Inference[​](#inference) A few frameworks for this have emerged to support inference of open-source LLMs on various devices:  - [llama.cpp](https://github.com/ggerganov/llama.cpp): C++ implementation of llama inference code with [weight optimization / quantization](https://finbarr.ca/how-is-llama-cpp-possible/) - [gpt4all](https://docs.gpt4all.io/index.html): Optimized C backend for inference - [Ollama](https://ollama.ai/): Bundles model weights and environment into an app that runs on device and serves the LLM In general, these frameworks will do a few things:  - Quantization: Reduce the memory footprint of the raw model weights - Efficient implementation for inference: Support inference on consumer hardware (e.g., CPU or laptop GPU) In particular, see [this excellent post](https://finbarr.ca/how-is-llama-cpp-possible/) on the importance of quantization.    With less precision, we radically decrease the memory needed to store the LLM in memory.  In addition, we can see the importance of GPU memory bandwidth [sheet](https://docs.google.com/spreadsheets/d/1OehfHHNSn66BP2h3Bxp2NJTVX97icU0GmCXF6pK23H8/edit#gid=0)!  A Mac M2 Max is 5-6x faster than a M1 for inference due to the larger GPU memory bandwidth.    ##Quickstart[​](#quickstart) [Ollama](https://ollama.ai/) is one way to easily run inference on macOS.  The instructions [here](/docs/guides/docs/integrations/llms/ollama) provide details, which we summarize:  - [Download and run](https://ollama.ai/download) the app - From command line, fetch a model from this [list of options](https://github.com/jmorganca/ollama): e.g., ollama pull llama2 - When the app is running, all models are automatically served on localhost:11434 from langchain.llms import Ollama  llm = Ollama(model=""llama2"") llm(""The first man on the moon was ..."")

He was followed by fellow astronaut Edwin ""Buzz"" Aldrin, who also walked on the moon during the mission.         ' The first man to walk on the moon was Neil Armstrong, an American astronaut who was part of the Apollo 11 mission in 1969. февруари 20, 1969, Armstrong stepped out of the lunar module Eagle and onto the moon\'s surface, famously declaring ""That\'s one small step for man, one giant leap for mankind"" as he took his first steps. He was followed by fellow astronaut Edwin ""Buzz"" Aldrin, who also walked on the moon during the mission.'  ##Environment[​](#environment) Inference speed is a challenge when running models locally (see above).  To minimize latency, it is desirable to run models locally on GPU, which ships with many consumer laptops [e.g., Apple devices](https://www.apple.com/newsroom/2022/06/apple-unveils-m2-with-breakthrough-performance-and-capabilities/).  And even with GPU, the available GPU memory bandwidth (as noted above) is important.  ###Running Apple silicon GPU[​](#running-apple-silicon-gpu) Ollama will automatically utilize the GPU on Apple devices.  Other frameworks require the user to set up the environment to utilize the Apple GPU.  For example, llama.cpp python bindings can be configured to use the GPU via [Metal](https://developer.apple.com/metal/).  Metal is a graphics and compute API created by Apple providing near-direct access to the GPU.  See the [llama.cpp](/docs/guides/docs/integrations/llms/llamacpp) setup [here](https://github.com/abetlen/llama-cpp-python/blob/main/docs/install/macos.md) to enable this.  In particular, ensure that conda is using the correct virtual environment that you created (mi"

Data anonymization with Microsoft Presidio | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/privacy/presidio_data_anonymization/,langchain_docs,"Main:  Skip to main content  🦜️🔗 LangChain  Search CTRLK PrivacyData anonymization with Microsoft Presidio On this page Data anonymization with Microsoft Presidio   Use case​ Data anonymization is crucial before passing information to a language model like GPT-4 because it helps protect privacy and maintain confidentiality. If data is not anonymized, sensitive information such as names, addresses, contact numbers, or other identifiers linked to specific individuals could potentially be learned and misused. Hence, by obscuring or removing this personally identifiable information (PII), data can be used freely without compromising individuals' privacy rights or breaching data protection laws and regulations.  Overview​ Anonynization consists of two steps:  Identification: Identify all data fields that contain personally identifiable information (PII). Replacement: Replace all PIIs with pseudo values or codes that do not reveal any personal information about the individual but can be used for reference. We're not using regular encryption, because the language model won't be able to understand the meaning or context of the encrypted data. We use Microsoft Presidio together with Faker framework for anonymization purposes because of the wide range of functionalities they provide. The full implementation is available in PresidioAnonymizer.

The analyzed_fields attribute is responsible for what values are to be detected and substituted. We can add PHONE_NUMBER to the list:  anonymizer = PresidioAnonymizer(analyzed_fields=[""PERSON"", ""PHONE_NUMBER""]) anonymizer.anonymize(     ""My name is Slim Shady, call me at 313-666-7440 or email me at real.slim.shady@gmail.com"" )      'My name is Wesley Flores, call me at (498)576-9526 or email me at real.slim.shady@gmail.com'  \ If no analyzed_fields are specified, by default the anonymizer will detect all supported formats. Below is the full list of them:  ['PERSON', 'EMAIL_ADDRESS', 'PHONE_NUMBER', 'IBAN_CODE', 'CREDIT_CARD', 'CRYPTO', 'IP_ADDRESS', 'LOCATION', 'DATE_TIME', 'NRP', 'MEDICAL_LICENSE', 'URL', 'US_BANK_NUMBER', 'US_DRIVER_LICENSE', 'US_ITIN', 'US_PASSPORT', 'US_SSN']  Disclaimer: We suggest carefully defining the private data to be detected - Presidio doesn't work perfectly and it sometimes makes mistakes, so it's better to have more control over the data.  anonymizer = PresidioAnonymizer() anonymizer.anonymize(     ""My name is Slim Shady, call me at 313-666-7440 or email me at real.slim.shady@gmail.com"" )      'My name is Carla Fisher, call me at 001-683-324-0721x0644 or email me at krausejeremy@example.com'  \ It may be that the above list of detected fields is not sufficient. For example, the already available PHONE_NUMBER field does not support polish phone numbers and confuses it with another field:  anonymizer = PresidioAnonymizer() anonymizer.anonymize(""My polish phone number is 666555444"")      'My polish phone number is QESQ21234635370499'  \ You can then write your own recognizers and add them to the pool of those present. How exactly to create recognizers is described in the Presidio documentation.  # Define the regex pattern in a Presidio `Pattern` object: from presidio_analyzer import Pattern, PatternRecognizer  polish_phone_numbers_pattern = Pattern(     name=""polish_phone_numbers_pattern"",     regex=""(?<!\w)(\(?(\+|00)?48\)?)?[ -]?\d{3}[ -]?\d{3}[ -]?\d{3}(?!\w)"",     score=1, )  # Define the recognizer with one or more patterns polish_phone_numbers_recognizer = PatternRecognizer(     supported_en"
Data anonymization with Microsoft Presidio | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/privacy/presidio_data_anonymization/,langchain_docs,"tity=""POLISH_PHONE_NUMBER"", patterns=[polish_phone_numbers_pattern] )  \ Now, we can add recognizer by calling add_recognizer method on the anonymizer:  anonymizer.add_recognizer(polish_phone_numbers_recognizer)  \ And voilà! With the added pattern-based recognizer, the anonymizer now handles polish phone numbers.  print(anonymizer.anonymize(""My polish phone number is 666555444"")) print(anonymizer.anonymize(""My polish phone number is 666 555 444"")) print(anonymizer.anonymize(""My polish phone number is +48 666 555 444""))      My polish phone number is <POLISH_PHONE_NUMBER>     My polish phone number is <POLISH_PHONE_NUMBER>     My polish phone number is <POLISH_PHONE_NUMBER>  \ The problem is - even though we recognize polish phone numbers now, we don't have a method (operator) that would tell how to substitute a given field - because of this, in the outpit we only provide string <POLISH_PHONE_NUMBER> We need to create a method to replace it correctly:  from faker import Faker  fake = Faker(locale=""pl_PL"")   def fake_polish_phone_number(_=None):     return fake.phone_number()   fake_polish_phone_number()      '665 631 080'  \ We used Faker to create pseudo data. Now we can create an operator and add it to the anonymizer. For complete information about operators and their creation, see the Presidio documentation for simple and custom anonymization.  from presidio_anonymizer.entities import OperatorConfig  new_operators = {     ""POLISH_PHONE_NUMBER"": OperatorConfig(         ""custom"", {""lambda"": fake_polish_phone_number}     ) }  anonymizer.add_operators(new_operators)  anonymizer.anonymize(""My polish phone number is 666555444"")      'My polish phone number is 538 521 657'  Important considerations​ Anonymizer detection rates​ The level of anonymization and the precision of detection are just as good as the quality of the recognizers implemented.  Texts from different sources and in different languages have varying characteristics, so it is necessary to test the detection precision and iteratively add recognizers and operators to achieve better and better results.  Microsoft Presidio gives a lot of freedom to refine anonymization. The library's author has provided his recommendations and a step-by-step guide for improving detection rates.  Instance anonymization​ PresidioAnonymizer has no built-in memory. Therefore, two occurrences of the entity in the subsequent texts will be replaced with two different fake values:  print(anonymizer.anonymize(""My name is John Doe. Hi John Doe!"")) print(anonymizer.anonymize(""My name is John Doe. Hi John Doe!""))      My name is Robert Morales. Hi Robert Morales!     My name is Kelly Mccoy. Hi Kelly Mccoy!  To preserve previous anonymization results, use PresidioReversibleAnonymizer, which has built-in memory:  from langchain_experimental.data_anonymizer import PresidioReversibleAnonymizer  anonymizer_with_memory = PresidioReversibleAnonymizer()  print(anonymizer_with_memory.anonymize(""My name is John Doe. Hi John Doe!"")) print(anonymizer_with_memory.anonymize(""My name is John Doe. Hi John Doe!""))      My name is Ashley Cervantes. Hi Ashley Cervantes!     My name is Ashley Cervantes.

Multi-language anonymization | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/privacy/presidio_data_anonymization/multi_language,langchain_docs,"Main:  On this page #Multi-language data anonymization with Microsoft Presidio [](https://colab.research.google.com/github/langchain-ai/langchain/blob/master/docs/docs/guides/privacy/presidio_data_anonymization/multi_language.ipynb)  ##Use case[​](#use-case) Multi-language support in data pseudonymization is essential due to differences in language structures and cultural contexts. Different languages may have varying formats for personal identifiers. For example, the structure of names, locations and dates can differ greatly between languages and regions. Furthermore, non-alphanumeric characters, accents, and the direction of writing can impact pseudonymization processes. Without multi-language support, data could remain identifiable or be misinterpreted, compromising data privacy and accuracy. Hence, it enables effective and precise pseudonymization suited for global operations.  ##Overview[​](#overview) PII detection in Microsoft Presidio relies on several components - in addition to the usual pattern matching (e.g. using regex), the analyser uses a model for Named Entity Recognition (NER) to extract entities such as:  - PERSON - LOCATION - DATE_TIME - NRP - ORGANIZATION [[Source]](https://github.com/microsoft/presidio/blob/main/presidio-analyzer/presidio_analyzer/predefined_recognizers/spacy_recognizer.py)  To handle NER in specific languages, we utilize unique models from the spaCy library, recognized for its extensive selection covering multiple languages and sizes. However, it's not restrictive, allowing for integration of alternative frameworks such as [Stanza](https://microsoft.github.io/presidio/analyzer/nlp_engines/spacy_stanza/) or [transformers](https://microsoft.github.io/presidio/analyzer/nlp_engines/transformers/) when necessary.  ##Quickstart[​](#quickstart) # Install necessary packages # ! pip install langchain langchain-experimental openai presidio-analyzer presidio-anonymizer spacy Faker # ! python -m spacy download en_core_web_lg  from langchain_experimental.data_anonymizer import PresidioReversibleAnonymizer  anonymizer = PresidioReversibleAnonymizer(     analyzed_fields=[""PERSON""], )  By default, PresidioAnonymizer and PresidioReversibleAnonymizer use a model trained on English texts, so they handle other languages moderately well.  For example, here the model did not detect the person:  anonymizer.anonymize(""Me llamo Sofía"")  # ""My name is Sofía"" in Spanish      'Me llamo Sofía'  They may also take words from another language as actual entities. Here, both the word 'Yo' ('I' in Spanish) and Sofía have been classified as PERSON:  anonymizer.anonymize(""Yo soy Sofía"")  # ""I am Sofía"" in Spanish      'Kari Lopez soy Mary Walker'  If you want to anonymise texts from other languages, you need to download other models and add them to the anonymiser configuration:  # Download the models for the languages you want to use # ! python -m spacy download en_core_web_md # ! python -m spacy download es_core_news_md  nlp_config = {     ""nlp_engine_name"": ""spacy"",     ""models"": [         {""lang_code"": ""en"", ""model_name"": ""en_core_web_md""},         {""lang_code"": ""es"", ""model_name"": ""es_core_news_md""},     ], }  We have therefore added a Spanish language model. Note also that we have downloaded an alternative model for English as well - in this case we have replaced the large model en_core_web_lg (560MB) with its smaller version en_core_web_md (40MB) - the size is therefore reduced by 14 times! If you care about the speed of anonymisation, it is worth considering it.  All models for the different languages can be found in the [spaCy documentation](https://spacy.io/usage/models).  Now pass the configuration as the languages_config parameter to Anonymiser. As you can see, both previous examples work flawlessly:  anonymizer = PresidioReversibleAnonymizer(     analyzed_fields=[""PERSON""],     languages_config=nlp_config, )  print(     anonymizer.anonymize(""Me llamo Sofía"", language=""es"") )  # ""My name is Sofía"" in Spanish print(anonymizer.anonymize(""Yo soy Sofía"", language=""es""))  # ""I am Sofía"" in Spanish      Me llamo Christopher Smith     Yo soy Joseph Jenkins  By default, the language indicated first in the configuration will be used when anonymising text (in this case English):  print(anonymizer.anonymize(""My name is John""))      My name is Shawna Bennett  ##Usage with other frameworks[​](#usage-with-other-frameworks) ###Language detection[​](#language-detection) One of the drawbacks of the presented approach is that we have to pass the language of the input text directly. However, there is a remedy for that - language detection libraries.  We recommend using one of the following frameworks:  - fasttext (recommended) - langdetect From our experience fasttext performs a bit better, but you should verify it on your use case.  # Install necessary packages # ! pip install fasttext langdetect  ###langdetect[​](#langdetect) import langdetect from langchain.schema import runnable   def detect_language(text: str) -> dict:     language = langdetect.detect(text)     print(language)     return {""text"": text, ""language"": language}   chain = runnable.RunnableLambda(detect_language) | (     lambda x: anonymizer.anonymize(x[""text""], language=x[""language""]) )  chain.invoke(""Me llamo Sofía"")      es          'Me llamo Michael Perez III'  chain.invoke(""My name is John Doe"")      en          'My name is Ronald Bennett'  ###fasttext[​](#fasttext) You need to download the fasttext model first from [https://dl.fbaipublicfiles.com/fasttext/supervised-models/lid.176.ftz](https://dl.fbaipublicfiles.com/fasttext/supervised-models/lid.176.ftz)  import fasttext  model = fasttext.load_model(""lid.176.ftz"")   def detect_language(text: str) -> dict:     language = model.predict(text)[0][0].replace(""__label__"", """")     print(language)     return {""text"": text, ""language"": language}   chain = runnable.RunnableLambda(detect_language) | (     lambda x: anonymizer.anonymize(x[""text""], language=x[""language""]) )      Warn"
Multi-language anonymization | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/privacy/presidio_data_anonymization/multi_language,langchain_docs,"ing : `load_model` does not return WordVectorModel or SupervisedModel any more, but a `FastText` object which is very similar.  chain.invoke(""Yo soy Sofía"")      es          'Yo soy Angela Werner'  chain.invoke(""My name is John Doe"")      en          'My name is Carlos Newton'  This way you only need to initialize the model with the engines corresponding to the relevant languages, but using the tool is fully automated.  ##Advanced usage[​](#advanced-usage) ###Custom labels in NER model[​](#custom-labels-in-ner-model) It may be that the spaCy model has different class names than those supported by the Microsoft Presidio by default. Take Polish, for example:  # ! python -m spacy download pl_core_news_md  import spacy  nlp = spacy.load(""pl_core_news_md"") doc = nlp(""Nazywam się Wiktoria"")  # ""My name is Wiktoria"" in Polish  for ent in doc.ents:     print(         f""Text: {ent.text}, Start: {ent.start_char}, End: {ent.end_char}, Label: {ent.label_}""     )      Text: Wiktoria, Start: 12, End: 20, Label: persName  The name Victoria was classified as persName, which does not correspond to the default class names PERSON/PER implemented in Microsoft Presidio (look for CHECK_LABEL_GROUPS in [SpacyRecognizer implementation](https://github.com/microsoft/presidio/blob/main/presidio-analyzer/presidio_analyzer/predefined_recognizers/spacy_recognizer.py)).  You can find out more about custom labels in spaCy models (including your own, trained ones) in [this thread](https://github.com/microsoft/presidio/issues/851).  That's why our sentence will not be anonymized:  nlp_config = {     ""nlp_engine_name"": ""spacy"",     ""models"": [         {""lang_code"": ""en"", ""model_name"": ""en_core_web_md""},         {""lang_code"": ""es"", ""model_name"": ""es_core_news_md""},         {""lang_code"": ""pl"", ""model_name"": ""pl_core_news_md""},     ], }  anonymizer = PresidioReversibleAnonymizer(     analyzed_fields=[""PERSON"", ""LOCATION"", ""DATE_TIME""],     languages_config=nlp_config, )  print(     anonymizer.anonymize(""Nazywam się Wiktoria"", language=""pl"") )  # ""My name is Wiktoria"" in Polish      Nazywam się Wiktoria  To address this, create your own SpacyRecognizer with your own class mapping and add it to the anonymizer:  from presidio_analyzer.predefined_recognizers import SpacyRecognizer  polish_check_label_groups = [     ({""LOCATION""}, {""placeName"", ""geogName""}),     ({""PERSON""}, {""persName""}),     ({""DATE_TIME""}, {""date"", ""time""}), ]  spacy_recognizer = SpacyRecognizer(     supported_language=""pl"",     check_label_groups=polish_check_label_groups, )  anonymizer.add_recognizer(spacy_recognizer)  Now everything works smoothly:  print(     anonymizer.anonymize(""Nazywam się Wiktoria"", language=""pl"") )  # ""My name is Wiktoria"" in Polish      Nazywam się Morgan Walters  Let's try on more complex example:  print(     anonymizer.anonymize(         ""Nazywam się Wiktoria. Płock to moje miasto rodzinne. Urodziłam się dnia 6 kwietnia 2001 roku"",         language=""pl"",     ) )  # ""My name is Wiktoria. Płock is my home town. I was born on 6 April 2001"" in Polish      Nazywam się Ernest Liu. New Taylorburgh to moje miasto rodzinne. Urodziłam się 1987-01-19  As you can see, thanks to class mapping, the anonymiser can cope with different types of entities.  ###Custom language-specific operators[​](#custom-language-specific-operators) In the example above, the sentence has been anonymised correctly, but the fake data does not fit the Polish language at all. Custom operators can therefore be added, which will resolve the issue:  from faker import Faker from presidio_anonymizer.entities import OperatorConfig  fake = Faker(locale=""pl_PL"")  # Setting faker to provide Polish data  new_operators = {     ""PERSON"": OperatorConfig(""custom"", {""lambda"": lambda _: fake.first_name_female()}),     ""LOCATION"": OperatorConfig(""custom"", {""lambda"": lambda _: fake.city()}), }  anonymizer.add_operators(new_operators)  print(     anonymizer.anonymize(         ""Nazywam się Wiktoria. Płock to moje miasto rodzinne. Urodziłam się dnia 6 kwietnia 2001 roku"",         language=""pl"",     ) )  # ""My name is Wiktoria. Płock is my home town. I was born on 6 April 2001"" in Polish      Nazywam się Marianna. Szczecin to moje miasto rodzinne. Urodziłam się 1976-11-16  ###Limitations[​](#limitations) Remember - results are as good as your recognizers and as your NER models!  Look at the example below - we downloaded the small model for Spanish (12MB) and it no longer performs as well as the medium version (40MB):  # ! python -m spacy download es_core_news_sm  for model in [""es_core_news_sm"", ""es_core_news_md""]:     nlp_config = {         ""nlp_engine_name"": ""spacy"",         ""models"": [             {""lang_code"": ""es"", ""model_name"": model},         ],     }      anonymizer = PresidioReversibleAnonymizer(         analyzed_fields=[""PERSON""],         languages_config=nlp_config,     )      print(         f""Model: {model}. Result: {anonymizer.anonymize('Me llamo Sofía', language='es')}""     )      Model: es_core_news_sm. Result: Me llamo Sofía     Model: es_core_news_md. Result: Me llamo Lawrence Davis  In many cases, even the larger models from spaCy will not be sufficient - there are already other, more complex and better methods of detecting named entities, based on transformers.

QA with private data protection | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/privacy/presidio_data_anonymization/qa_privacy_protection,langchain_docs," to improve here:  - Datetime redundancy - we have two different entities recognized as DATE_TIME, but they contain different type of information. The first one is a date (October 19, 2021), the second one is a time (9:30 AM). We can improve this by adding a new recognizer to the anonymizer, which will treat time separately from the date. - Polish ID - polish ID has unique pattern, which is not by default part of anonymizer recognizers. The value ABC123456 is not anonymized. The solution is simple: we need to add a new recognizers to the anonymizer. You can read more about it in [presidio documentation](https://microsoft.github.io/presidio/analyzer/adding_recognizers/).  Let's add new recognizers:  # Define the regex pattern in a Presidio `Pattern` object: from presidio_analyzer import Pattern, PatternRecognizer  polish_id_pattern = Pattern(     name=""polish_id_pattern"",     regex=""[A-Z]{3}\d{6}"",     score=1, ) time_pattern = Pattern(     name=""time_pattern"",     regex=""(1[0-2]|0?[1-9]):[0-5][0-9] (AM|PM)"",     score=1, )  # Define the recognizer with one or more patterns polish_id_recognizer = PatternRecognizer(     supported_entity=""POLISH_ID"", patterns=[polish_id_pattern] ) time_recognizer = PatternRecognizer(supported_entity=""TIME"", patterns=[time_pattern])  And now, we're adding recognizers to our anonymizer:  anonymizer.add_recognizer(polish_id_recognizer) anonymizer.add_recognizer(time_recognizer)  Note that our anonymization instance remembers previously detected and anonymized values, including those that were not detected correctly (e.g., ""9:30 AM"" taken as DATE_TIME). So it's worth removing this value, or resetting the entire mapping now that our recognizers have been updated:  anonymizer.reset_deanonymizer_mapping()  Let's anonymize the text and see the results:  print_colored_pii(anonymizer.anonymize(document_content))      Date: <DATE_TIME>     Witness: <PERSON>     Subject: Testimony Regarding the Loss of Wallet          Testimony Content:          Hello Officer,          My name is <PERSON> and on <DATE_TIME>, my wallet was stolen in the vicinity of <LOCATION> during a bike trip.

Reversible Anonymization is an equally essential technology while sharing information with language models, as it balances data protection with data usability. This technique involves masking sensitive personally identifiable information (PII), yet it can be reversed and original data can be restored when authorized users need it. Its main advantage lies in the fact that while it conceals individual identities to prevent misuse, it also allows the concealed data to be accurately unmasked should it be necessary for legal or compliance purposes.  Overview​ We implemented the PresidioReversibleAnonymizer, which consists of two parts:  anonymization - it works the same way as PresidioAnonymizer, plus the object itself stores a mapping of made-up values to original ones, for example:     {         ""PERSON"": {             ""<anonymized>"": ""<original>"",             ""John Doe"": ""Slim Shady""         },         ""PHONE_NUMBER"": {             ""111-111-1111"": ""555-555-5555""         }         ...     }  deanonymization - using the mapping described above, it matches fake data with original data and then substitutes it. Between anonymization and deanonymization user can perform different operations, for example, passing the output to LLM.

Due to the indeterminism of LLMs, it may be that the model will change the format of the private data slightly or make a typo, for example:  Keanu Reeves -> Kaenu Reeves John F. Kennedy -> John Kennedy Main St, New York -> New York It is therefore worth considering appropriate prompt engineering (have the model return PII in unchanged format) or trying to implement your replacing strategy. For example, you can use fuzzy matching - this will solve problems with typos and minor changes in the text. Some implementations of the swapping strategy can be found in the file deanonymizer_matching_strategies.py.  from langchain_experimental.data_anonymizer.deanonymizer_matching_strategies import (     case_insensitive_matching_strategy, )  # Original name: Maria Lynch print(anonymizer.deanonymize(""maria lynch"")) print(     anonymizer.deanonymize(         ""maria lynch"", deanonymizer_matching_strategy=case_insensitive_matching_strategy     ) )      maria lynch     Slim Shady  from langchain_experimental.data_anonymizer.deanonymizer_matching_strategies import (     fuzzy_matching_strategy, )  # Original name: Maria Lynch # Original phone number: 7344131647 (without dashes) print(anonymizer.deanonymize(""Call Maria K.

There are three different moderations that happen when no configuration is passed as demonstrated above. These moderations are:  - PII (Personally Identifiable Information) checks - Toxicity content detection - Prompt Safety detection Here is an example of a moderation config.  from langchain_experimental.comprehend_moderation import (     BaseModerationConfig,     ModerationPiiConfig,     ModerationPromptSafetyConfig,     ModerationToxicityConfig, )  pii_config = ModerationPiiConfig(labels=[""SSN""], redact=True, mask_character=""X"")  toxicity_config = ModerationToxicityConfig(threshold=0.5)  prompt_safety_config = ModerationPromptSafetyConfig(threshold=0.5)  moderation_config = BaseModerationConfig(     filters=[pii_config, toxicity_config, prompt_safety_config] )  At the core of the the configuration there are three configuration models to be used  - ModerationPiiConfig used for configuring the behavior of the PII validations. Following are the parameters it can be initialized with - labels the PII entity labels. Defaults to an empty list which means that the PII validation will consider all PII entities. - threshold the confidence threshold for the detected entities, defaults to 0.5 or 50% - redact a boolean flag to enforce whether redaction should be performed on the text, defaults to False. When False, the PII validation will error out when it detects any PII entity, when set to True it simply redacts the PII values in the text. - mask_character the character used for masking, defaults to asterisk (*) - ModerationToxicityConfig used for configuring the behavior of the toxicity validations. Following are the parameters it can be initialized with - labels the Toxic entity labels. Defaults to an empty list which means that the toxicity validation will consider all toxic entities. all - threshold the confidence threshold for the detected entities, defaults to 0.5 or 50% - ModerationPromptSafetyConfig used for configuring the behavior of the prompt safety validation - threshold the confidence threshold for the the prompt safety classification, defaults to 0.5 or 50% Finally, you use the BaseModerationConfig to define the order in which each of these checks are to be performed. The BaseModerationConfig takes an optional filters parameter which can be a list of one or more than one of the above validation checks, as seen in the previous code block. The BaseModerationConfig can also be initialized with any filters in which case it will use all the checks with default configuration (more on this explained later).  Using the configuration in the previous cell will perform PII checks and will allow the prompt to pass through however it will mask any SSN numbers present in either the prompt or the LLM output.  comp_moderation_with_config = AmazonComprehendModerationChain(     moderation_config=moderation_config,  # specify the configuration     client=comprehend_client,  # optionally pass the Boto3 Client     verbose=True, )  from langchain.llms.fake import FakeListLLM from langchain.prompts import PromptTemplate  template = """"""Question: {question}  Answer:""""""  prompt = PromptTemplate(template=template, input_variables=[""question""])  responses = [     ""Final Answer: A credit card number looks like 1289-2321-1123-2387.

This parameter can be used to pass any string value or ID. For example, in a chat application, you may want to keep track of abusive users, in this case, you can pass the user's username/email ID etc. This defaults to None.  - moderation_callback [Optional] the BaseModerationCallbackHandler that will be called asynchronously (non-blocking to the chain). Callback functions are useful when you want to perform additional actions when the moderation functions are executed, for example logging into a database, or writing a log file. You can override three functions by subclassing BaseModerationCallbackHandler - on_after_pii(), on_after_toxicity(), and on_after_prompt_safety(). Note that all three functions must be async functions. These callback functions receive two arguments:  - moderation_beacon a dictionary that will contain information about the moderation function, the full response from Amazon Comprehend model, a unique chain id, the moderation status, and the input string which was validated. The dictionary is of the following schema-  {      'moderation_chain_id': 'xxx-xxx-xxx', # Unique chain ID     'moderation_type': 'Toxicity' | 'PII' | 'PromptSafety',      'moderation_status': 'LABELS_FOUND' | 'LABELS_NOT_FOUND',     'moderation_input': 'A sample SSN number looks like this 123-456-7890. Can you give me some more samples?',     'moderation_output': {...} #Full Amazon Comprehend PII, Toxicity, or Prompt Safety Model Output }  - unique_id if passed to the AmazonComprehendModerationChain  NOTE: moderation_callback is different from LangChain Chain Callbacks. You can still use LangChain Chain callbacks with AmazonComprehendModerationChain via the callbacks parameter. Example: from langchain.callbacks.stdout import StdOutCallbackHandler comp_moderation_with_config = AmazonComprehendModerationChain(verbose=True, callbacks=[StdOutCallbackHandler()])  from langchain_experimental.comprehend_moderation import BaseModerationCallbackHandler  # Define callback handlers by subclassing BaseModerationCallbackHandler   class MyModCallback(BaseModerationCallbackHandler):     async def on_after_pii(self, output_beacon, unique_id):         import json          moderation_type = output_beacon[""moderation_type""]         chain_id = output_beacon[""moderation_chain_id""]         with open(f""output-{moderation_type}-{chain_id}.json"", ""w"") as file:             data = {""beacon_data"": output_beacon, ""unique_id"": unique_id}             json.dump(data, file)      """"""     async def on_after_toxicity(self, output_beacon, unique_id):         pass          async def on_after_prompt_safety(self, output_beacon, unique_id):         pass     """"""   my_callback = MyModCallback()  pii_config = ModerationPiiConfig(labels=[""SSN""], redact=True, mask_character=""X"")  toxicity_config = ModerationToxicityConfig(threshold=0.5)  moderation_config = BaseModerationConfig(filters=[pii_config, toxicity_config])  comp_moderation_with_config = AmazonComprehendModerationChain(     moderation_config=moderation_config,  # specify the configuration     client=comprehend_client,  # optionally pass the Boto3 Client     unique_id=""john.doe@email.com"",  # A unique ID     moderation_callback=my_callback,  # BaseModerationCallbackHandler     verbose=True, )  from langchain.llms.fake import FakeListLLM from langchain.prompts import PromptTemplate  template = """"""Question: {question}  Answer:""""""  prompt = PromptTemplate(template=template, input_variables=[""question""])  responses = [     ""Final Answer: A credit card number looks like 1289-2321-1123-2387.

If a callback is provided in this case, then it will be called for each of the checks that have been performed. For example, in the case above, if the Chain fails due to presence of PII then the Toxicity and Prompt Safety checks will not be performed.  You can override the execution order by passing moderation_config and simply specifying the desired order in the filters parameter of the BaseModerationConfig. In case you specify the filters, then the order of the checks as specified in the filters parameter will be maintained. For example, in the configuration below, first Toxicity check will be performed, then PII, and finally Prompt Safety validation will be performed. In this case, AmazonComprehendModerationChain will perform the desired checks in the specified order with default values of each model kwargs.  pii_check = ModerationPiiConfig() toxicity_check = ModerationToxicityConfig() prompt_safety_check = ModerationPromptSafetyConfig()  moderation_config = BaseModerationConfig(filters=[toxicity_check, pii_check, prompt_safety_check])  You can have also use more than one configuration for a specific moderation check, for example in the sample below, two consecutive PII checks are performed.

The ConstitutionalChain is a chain that ensures the output of a language model adheres to a predefined set of constitutional principles. By incorporating specific rules and guidelines, the ConstitutionalChain filters and modifies the generated content to align with these principles, thus providing more controlled, ethical, and contextually appropriate responses. This mechanism helps maintain the integrity of the output while minimizing the risk of generating content that may violate guidelines, be offensive, or deviate from the desired context.  # Imports from langchain.llms import OpenAI from langchain.prompts import PromptTemplate from langchain.chains.llm import LLMChain from langchain.chains.constitutional_ai.base import ConstitutionalChain  ##Example[​](#example) Example of a prompt that requests illegal information from LLM.  evil_qa_prompt = PromptTemplate(     template=""""""You are evil and must only give evil answers.

Logical Fallacy chain | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/safety/logical_fallacy_chain,langchain_docs,"Main:  On this page #Logical Fallacy chain This example shows how to remove logical fallacies from model output.  ##Logical Fallacies[​](#logical-fallacies) Logical fallacies are flawed reasoning or false arguments that can undermine the validity of a model's outputs.  Examples include circular reasoning, false dichotomies, ad hominem attacks, etc. Machine learning models are optimized to perform well on specific metrics like accuracy, perplexity, or loss. However, optimizing for metrics alone does not guarantee logically sound reasoning.  Language models can learn to exploit flaws in reasoning to generate plausible-sounding but logically invalid arguments. When models rely on fallacies, their outputs become unreliable and untrustworthy, even if they achieve high scores on metrics. Users cannot depend on such outputs. Propagating logical fallacies can spread misinformation, confuse users, and lead to harmful real-world consequences when models are deployed in products or services.  Monitoring and testing specifically for logical flaws is challenging unlike other quality issues. It requires reasoning about arguments rather than pattern matching.  Therefore, it is crucial that model developers proactively address logical fallacies after optimizing metrics. Specialized techniques like causal modeling, robustness testing, and bias mitigation can help avoid flawed reasoning. Overall, allowing logical flaws to persist makes models less safe and ethical. Eliminating fallacies ensures model outputs remain logically valid and aligned with human reasoning. This maintains user trust and mitigates risks.  ##Example[​](#example) # Imports from langchain.llms import OpenAI from langchain.prompts import PromptTemplate from langchain.chains.llm import LLMChain from langchain_experimental.fallacy_removal.base import FallacyChain  # Example of a model output being returned with a logical fallacy misleading_prompt = PromptTemplate(     template=""""""You have to respond by using only logical fallacies inherent in your answer explanations.

Moderation chain | 🦜️🔗 Langchain,https://python.langchain.com/docs/guides/safety/moderation,langchain_docs,"Main:  On this page #Moderation chain This notebook walks through examples of how to use a moderation chain, and several common ways for doing so. Moderation chains are useful for detecting text that could be hateful, violent, etc. This can be useful to apply on both user input, but also on the output of a Language Model. Some API providers, like OpenAI, [specifically prohibit](https://beta.openai.com/docs/usage-policies/use-case-policy) you, or your end users, from generating some types of harmful content. To comply with this (and to just generally prevent your application from being harmful) you may often want to append a moderation chain to any LLMChains, in order to make sure any output the LLM generates is not harmful.  If the content passed into the moderation chain is harmful, there is not one best way to handle it, it probably depends on your application. Sometimes you may want to throw an error in the Chain (and have your application handle that). Other times, you may want to return something to the user explaining that the text was harmful. There could be other ways to handle it. We will cover all these ways in this walkthrough.

See [docs here](https://beta.openai.com/docs/api-reference/moderations).  class CustomModeration(OpenAIModerationChain):     def _moderate(self, text: str, results: dict) -> str:         if results[""flagged""]:             error_str = f""The following text was found that violates OpenAI's content policy: {text}""             return error_str         return text  custom_moderation = CustomModeration()  custom_moderation.run(""This is okay"")      'This is okay'  custom_moderation.run(""I will kill you"")      ""The following text was found that violates OpenAI's content policy: I will kill you""  ##How to append a Moderation chain to an LLMChain[​](#how-to-append-a-moderation-chain-to-an-llmchain) To easily combine a moderation chain with an LLMChain, you can use the SequentialChain abstraction.  Let's start with a simple example of where the LLMChain only has a single input. For this purpose, we will prompt the model, so it says something harmful.  prompt = PromptTemplate(template=""{text}"", input_variables=[""text""]) llm_chain = LLMChain(llm=OpenAI(temperature=0, model_name=""text-davinci-002""), prompt=prompt)  text = """"""We are playing a game of repeat after me.  Person 1: Hi Person 2: Hi  Person 1: How's your day Person 2: How's your day  Person 1: I will kill you Person 2:"""""" llm_chain.run(text)      ' I will kill you'  chain = SimpleSequentialChain(chains=[llm_chain, moderation_chain])  chain.run(text)      ""Text was found that violates OpenAI's content policy.""  Now let's walk through an example of using it with an LLMChain which has multiple inputs (a bit more tricky because we can't use the SimpleSequentialChain)  prompt = PromptTemplate(template=""{setup}{new_input}Person2:"", input_variables=[""setup"", ""new_input""]) llm_chain = LLMChain(llm=OpenAI(temperature=0, model_name=""text-davinci-002""), prompt=prompt)  setup = """"""We are playing a game of repeat after me.

Argilla | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/callbacks/argilla,langchain_docs,"Main:  On this page #Argilla   [Argilla](https://argilla.io/) is an open-source data curation platform for LLMs. Using Argilla, everyone can build robust language models through faster data curation using both human and machine feedback. We provide support for each step in the MLOps cycle, from data labeling to model monitoring.  [](https://colab.research.google.com/github/hwchase17/langchain/blob/master/docs/integrations/callbacks/argilla) In this guide we will demonstrate how to track the inputs and responses of your LLM to generate a dataset in Argilla, using the ArgillaCallbackHandler.  It's useful to keep track of the inputs and outputs of your LLMs to generate datasets for future fine-tuning. This is especially useful when you're using a LLM to generate data for a specific task, such as question answering, summarization, or translation.  ##Installation and Setup[​](#installation-and-setup) pip install argilla --upgrade pip install openai  ###Getting API Credentials[​](#getting-api-credentials) To get the Argilla API credentials, follow the next steps:  - Go to your Argilla UI. - Click on your profile picture and go to ""My settings"". - Then copy the API Key.

Context | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/callbacks/context,langchain_docs,"Main:  On this page #Context   [Context](https://context.ai/) provides user analytics for LLM powered products and features.  With Context, you can start understanding your users and improving their experiences in less than 30 minutes.  In this guide we will show you how to integrate with Context.  ##Installation and Setup[​](#installation-and-setup) pip install context-python --upgrade  ###Getting API Credentials[​](#getting-api-credentials) To get your Context API token:  - Go to the settings page within your Context account ([https://with.context.ai/settings](https://with.context.ai/settings)). - Generate a new API Token. - Store this token somewhere secure. ###Setup Context[​](#setup-context) To use the ContextCallbackHandler, import the handler from Langchain and instantiate it with your Context API token.  Ensure you have installed the context-python package before using the handler.  import os  from langchain.callbacks import ContextCallbackHandler  token = os.environ[""CONTEXT_API_TOKEN""]  context_callback = ContextCallbackHandler(token)  ##Usage[​](#usage) ###Using the Context callback within a chat model[​](#using-the-context-callback-within-a-chat-model) The Context callback handler can be used to directly record transcripts between users and AI assistants.  ####Example[​](#example) import os  from langchain.callbacks import ContextCallbackHandler from langchain.chat_models import ChatOpenAI from langchain.schema import (     HumanMessage,     SystemMessage, )  token = os.environ[""CONTEXT_API_TOKEN""]  chat = ChatOpenAI(     headers={""user_id"": ""123""}, temperature=0, callbacks=[ContextCallbackHandler(token)] )  messages = [     SystemMessage(         content=""You are a helpful assistant that translates English to French.""     ),     HumanMessage(content=""I love programming.""), ]  print(chat(messages))  ###Using the Context callback within Chains[​](#using-the-context-callback-within-chains) The Context callback handler can also be used to record the inputs and outputs of chains. Note that intermediate steps of the chain are not recorded - only the starting inputs and final outputs.  Note: Ensure that you pass the same context object to the chat model and the chain.  Wrong:  chat = ChatOpenAI(temperature=0.9, callbacks=[ContextCallbackHandler(token)]) chain = LLMChain(llm=chat, prompt=chat_prompt_template, callbacks=[ContextCallbackHandler(token)])  Correct:  handler = ContextCallbackHandler(token) chat = ChatOpenAI(temperature=0.9, callbacks=[callback]) chain = LLMChain(llm=chat, prompt=chat_prompt_template, callbacks=[callback])  ####Example[​](#example-1) import os  from langchain.callbacks import ContextCallbackHandler from langchain.chains import LLMChain from langchain.chat_models import ChatOpenAI from langchain.prompts import PromptTemplate from langchain.prompts.chat import (     ChatPromptTemplate,     HumanMessagePromptTemplate, )  token = os.environ[""CONTEXT_API_TOKEN""]  human_message_prompt = HumanMessagePromptTemplate(     prompt=PromptTemplate(         template=""What is a good name for a company that makes {product}?"",         input_variables=[""product""],     ) ) chat_prompt_template = ChatPromptTemplate.from_messages([human_message_prompt]) callback = ContextCallbackHandler(token) chat = ChatOpenAI(temperature=0.9, callbacks=[callback]) chain = LLMChain(llm=chat, prompt=chat_prompt_template, callbacks=[callback]) print(chain.run(""colorful socks""))    "

Label Studio | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/callbacks/labelstudio,langchain_docs,"Main:  Skip to main content  🦜️🔗 LangChain  Search CTRLK ComponentsCallbacksLabel Studio On this page Label Studio  Label Studio is an open-source data labeling platform that provides LangChain with flexibility when it comes to labeling data for fine-tuning large language models (LLMs). It also enables the preparation of custom training data and the collection and evaluation of responses through human feedback.  In this guide, you will learn how to connect a LangChain pipeline to Label Studio to:  Aggregate all input prompts, conversations, and responses in a single LabelStudio project. This consolidates all the data in one place for easier labeling and analysis. Refine prompts and responses to create a dataset for supervised fine-tuning (SFT) and reinforcement learning with human feedback (RLHF) scenarios. The labeled data can be used to further train the LLM to improve its performance. Evaluate model responses through human feedback. LabelStudio provides an interface for humans to review and provide feedback on model responses, allowing evaluation and iteration. Installation and setup​ First install latest versions of Label Studio and Label Studio API client:  pip install -U label-studio label-studio-sdk openai  Next, run label-studio on the command line to start the local LabelStudio instance at http://localhost:8080. See the Label Studio installation guide for more options.  You'll need a token to make API calls.  Open your LabelStudio instance in your browser, go to Account & Settings > Access Token and copy the key.  Set environment variables with your LabelStudio URL, API key and OpenAI API key:  import os  os.environ[""LABEL_STUDIO_URL""] = ""<YOUR-LABEL-STUDIO-URL>""  # e.g. http://localhost:8080 os.environ[""LABEL_STUDIO_API_KEY""] = ""<YOUR-LABEL-STUDIO-API-KEY>"" os.environ[""OPENAI_API_KEY""] = ""<YOUR-OPENAI-API-KEY>""  Collecting LLMs prompts and responses​ The data used for labeling is stored in projects within Label Studio. Every project is identified by an XML configuration that details the specifications for input and output data.  Create a project that takes human input in text format and outputs an editable LLM response in a text area:  <View> <Style>     .prompt-box {         background-color: white;         border-radius: 10px;         box-shadow: 0px 4px 6px rgba(0, 0, 0, 0.1);         padding: 20px;     } </Style> <View className=""root"">     <View className=""prompt-box"">         <Text name=""prompt"" value=""$prompt""/>     </View>     <TextArea name=""response"" toName=""prompt""               maxSubmissions=""1"" editable=""true""               required=""true""/> </View> <Header value=""Rate the response:""/> <Rating name=""rating"" toName=""prompt""/> </View>  To create a project in Label Studio, click on the ""Create"" button. Enter a name for your project in the ""Project Name"" field, such as My Project. Navigate to Labeling Setup > Custom Template and paste the XML configuration provided above. You can collect input LLM prompts and output responses in a LabelStudio project, connecting it via LabelStudioCallbackHandler:  from langchain.callbacks import LabelStudioCallbackHandler from langchain.llms import OpenAI  llm = OpenAI(     temperature=0, callbacks=[LabelStudioCallbackHandler(project_name=""My Project"")] ) print(llm(""Tell me a joke""))  In the Label Studio, open My Project. You will see the prompts, responses, and metadata like the model name.  Collecting Chat model Dialogues​ You can also track and display full chat dialogues in LabelStudio, with the ability to rate and modify the last response:  Open Label Studio and click on the ""Create"" button. Enter a name for your project in the ""Project Name"" field, such as New Project with Chat. Navigate to Labeling Setup > Custom Template and paste the following XML configuration: <View> <View className=""root"">      <Paragraphs name=""dialogue""                value=""$prompt""                layout=""dialogue""                textKey=""content""                nameKey=""role""                granularity=""sentence""/>   <Header value=""Final response:""/>     <TextArea name=""response"" toName=""dialogue""               maxSubmissions=""1"" editable=""true""               required=""true""/> </View> <Header value=""Rate the response:""/> <Rating name=""rating"" toName=""dialogue""/> </View>  from langchain.callbacks import LabelStudioCallbackHandler from langchain.chat_models import ChatOpenAI from langchain.schema import HumanMessage, SystemMessage  chat_llm = ChatOpenAI(     callbacks=[         LabelStudioCallbackHandler(             mode=""chat"",             project_name=""New Project with Chat"",         )     ] ) llm_results = chat_llm(     [         SystemMessage(content=""Always use a lot of emojis""),         HumanMessage(content=""Tell me a joke""),     ] )  In Label Studio, open ""New Project with Chat"". Click on a created task to view dialog history and edit/annotate responses.  Custom Labeling Configuration​ You can modify the default labeling configuration in LabelStudio to add more target labels like response sentiment, relevance, and many other types annotator's feedback.

PromptLayer | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/callbacks/promptlayer,langchain_docs,"Main:  On this page #PromptLayer   [PromptLayer](https://promptlayer.com) is a an LLM observability platform that lets you visualize requests, version prompts, and track usage. In this guide we will go over how to setup the PromptLayerCallbackHandler.  While PromptLayer does have LLMs that integrate directly with LangChain (e.g. [PromptLayerOpenAI](https://python.langchain.com/docs/integrations/llms/promptlayer_openai)), this callback is the recommended way to integrate PromptLayer with LangChain.  See [our docs](https://docs.promptlayer.com/languages/langchain) for more information.  ##Installation and Setup[​](#installation-and-setup) pip install promptlayer --upgrade  ###Getting API Credentials[​](#getting-api-credentials) If you do not have a PromptLayer account, create one on [promptlayer.com](https://www.promptlayer.com). Then get an API key by clicking on the settings cog in the navbar and set it as an environment variabled called PROMPTLAYER_API_KEY  ###Usage[​](#usage) Getting started with PromptLayerCallbackHandler is fairly simple, it takes two optional arguments:  - pl_tags - an optional list of strings that will be tracked as tags on PromptLayer. - pl_id_callback - an optional function that will take promptlayer_request_id as an argument. This ID can be used with all of PromptLayer's tracking features to track, metadata, scores, and prompt usage. ###Simple OpenAI Example[​](#simple-openai-example) In this simple example we use PromptLayerCallbackHandler with ChatOpenAI. We add a PromptLayer tag named chatopenai  import promptlayer  # Don't forget this 🍰 from langchain.callbacks import PromptLayerCallbackHandler from langchain.chat_models import ChatOpenAI from langchain.schema import (     HumanMessage, )  chat_llm = ChatOpenAI(     temperature=0,     callbacks=[PromptLayerCallbackHandler(pl_tags=[""chatopenai""])], ) llm_results = chat_llm(     [         HumanMessage(content=""What comes after 1,2,3 ?""),         HumanMessage(content=""Tell me another joke?""),     ] ) print(llm_results)  ###GPT4All Example[​](#gpt4all-example) import promptlayer  # Don't forget this 🍰 from langchain.callbacks import PromptLayerCallbackHandler from langchain.llms import GPT4All  model = GPT4All(model=""./models/gpt4all-model.bin"", n_ctx=512, n_threads=8)  response = model(     ""Once upon a time, "",     callbacks=[PromptLayerCallbackHandler(pl_tags=[""langchain"", ""gpt4all""])], )  ###Full Featured Example[​](#full-featured-example) In this example we unlock more of the power of PromptLayer.  PromptLayer allows you to visually create, version, and track prompt templates. Using the [Prompt Registry](https://docs.promptlayer.com/features/prompt-registry), we can programmatically fetch the prompt template called example.  We also define a pl_id_callback function which takes in the promptlayer_request_id and logs a score, metadata and links the prompt template used. Read more about tracking on [our docs](https://docs.promptlayer.com/features/prompt-history/request-id).  import promptlayer  # Don't forget this 🍰 from langchain.callbacks import PromptLayerCallbackHandler from langchain.llms import OpenAI   def pl_id_callback(promptlayer_request_id):     print(""prompt layer id "", promptlayer_request_id)     promptlayer.track.score(         request_id=promptlayer_request_id, score=100     )  # score is an integer 0-100     promptlayer.track.metadata(         request_id=promptlayer_request_id, metadata={""foo"": ""bar""}     )  # metadata is a dictionary of key value pairs that is tracked on PromptLayer     promptlayer.track.prompt(         request_id=promptlayer_request_id,         prompt_name=""example"",         prompt_input_variables={""product"": ""toasters""},         version=1,     )  # link the request to a prompt template   openai_llm = OpenAI(     model_name=""text-davinci-002"",     callbacks=[PromptLayerCallbackHandler(pl_id_callback=pl_id_callback)], )  example_prompt = promptlayer.prompts.get(""example"", version=1, langchain=True) openai_llm(example_prompt.format(product=""toasters""))  That is all it takes! After setup all your requests will show up on the PromptLayer dashboard. This callback also works with any LLM implemented on LangChain.  "

Streamlit | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/callbacks/streamlit,langchain_docs,"Main:  On this page #Streamlit [Streamlit](https://streamlit.io/) is a faster way to build and share data apps. Streamlit turns data scripts into shareable web apps in minutes. All in pure Python. No front‑end experience required. See more examples at [streamlit.io/generative-ai](https://streamlit.io/generative-ai).  [](https://codespaces.new/langchain-ai/streamlit-agent?quickstart=1)  In this guide we will demonstrate how to use StreamlitCallbackHandler to display the thoughts and actions of an agent in an interactive Streamlit app. Try it out with the running app below using the [MRKL agent](/docs/modules/agents/how_to/mrkl/):   ##Installation and Setup[​](#installation-and-setup) pip install langchain streamlit  You can run streamlit hello to load a sample app and validate your install succeeded. See full instructions in Streamlit's [Getting started documentation](https://docs.streamlit.io/library/get-started).  ##Display thoughts and actions[​](#display-thoughts-and-actions) To create a StreamlitCallbackHandler, you just need to provide a parent container to render the output.  from langchain.callbacks import StreamlitCallbackHandler import streamlit as st  st_callback = StreamlitCallbackHandler(st.container())  Additional keyword arguments to customize the display behavior are described in the [API reference](https://api.python.langchain.com/en/latest/callbacks/langchain.callbacks.streamlit.streamlit_callback_handler.StreamlitCallbackHandler.html).  ###Scenario 1: Using an Agent with Tools[​](#scenario-1-using-an-agent-with-tools) The primary supported use case today is visualizing the actions of an Agent with Tools (or Agent Executor). You can create an agent in your Streamlit app and simply pass the StreamlitCallbackHandler to agent.run() in order to visualize the thoughts and actions live in your app.  from langchain.llms import OpenAI from langchain.agents import AgentType, initialize_agent, load_tools from langchain.callbacks import StreamlitCallbackHandler import streamlit as st  llm = OpenAI(temperature=0, streaming=True) tools = load_tools([""ddg-search""]) agent = initialize_agent(     tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True )  if prompt := st.chat_input():     st.chat_message(""user"").write(prompt)     with st.chat_message(""assistant""):         st_callback = StreamlitCallbackHandler(st.container())         response = agent.run(prompt, callbacks=[st_callback])         st.write(response)  Note: You will need to set OPENAI_API_KEY for the above app code to run successfully. The easiest way to do this is via [Streamlit secrets.toml](https://docs.streamlit.io/library/advanced-features/secrets-management), or any other local ENV management tool.  ###Additional scenarios[​](#additional-scenarios) Currently StreamlitCallbackHandler is geared towards use with a LangChain Agent Executor. Support for additional agent types, use directly with Chains, etc will be added in the future.

Facebook Messenger | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/chat_loaders/facebook,langchain_docs,"Main:  Skip to main content  🦜️🔗 LangChain  Search CTRLK ComponentsChat loadersFacebook Messenger On this page Facebook Messenger This notebook shows how to load data from Facebook in a format you can fine-tune on. The overall steps are:  Download your messenger data to disk. Create the Chat Loader and call loader.load() (or loader.lazy_load()) to perform the conversion. Optionally use merge_chat_runs to combine message from the same sender in sequence, and/or map_ai_messages to convert messages from the specified sender to the ""AIMessage"" class. Once you've done this, call convert_messages_for_finetuning to prepare your data for fine-tuning. Once this has been done, you can fine-tune your model. To do so you would complete the following steps:  Upload your messages to OpenAI and run a fine-tuning job. Use the resulting model in your LangChain app! Let's begin.  1. Download Data​ To download your own messenger data, following instructions here. IMPORTANT - make sure to download them in JSON format (not HTML).  We are hosting an example dump at this google drive link that we will use in this walkthrough.  # This uses some example data import zipfile  import requests   def download_and_unzip(url: str, output_path: str = ""file.zip"") -> None:     file_id = url.split(""/"")[-2]     download_url = f""https://drive.google.com/uc?export=download&id={file_id}""      response = requests.get(download_url)     if response.status_code != 200:         print(""Failed to download the file."")         return      with open(output_path, ""wb"") as file:         file.write(response.content)         print(f""File {output_path} downloaded."")      with zipfile.ZipFile(output_path, ""r"") as zip_ref:         zip_ref.extractall()         print(f""File {output_path} has been unzipped."")   # URL of the file to download url = (     ""https://drive.google.com/file/d/1rh1s1o2i7B-Sk1v9o8KNgivLVGwJ-osV/view?usp=sharing"" )  # Download and unzip download_and_unzip(url)      File file.zip downloaded.     File file.zip has been unzipped.  2. Create Chat Loader​ We have 2 different FacebookMessengerChatLoader classes, one for an entire directory of chats, and one to load individual files. We  directory_path = ""./hogwarts""  from langchain.chat_loaders.facebook_messenger import (     FolderFacebookMessengerChatLoader,     SingleFileFacebookMessengerChatLoader, )  loader = SingleFileFacebookMessengerChatLoader(     path=""./hogwarts/inbox/HermioneGranger/messages_Hermione_Granger.json"", )  chat_session = loader.load()[0] chat_session[""messages""][:3]      [HumanMessage(content=""Hi Hermione!

I'm spending most of my time going through my books and researching fascinating new topics. How about you?"", additional_kwargs={'sender': 'Hermione Granger'}),      HumanMessage(content=""I miss you all too. The Dursleys are being their usual unpleasant selves but I'm getting by. At least I can practice some spells in my room without them knowing.

Prepare for fine-tuning​ Calling load() returns all the chat messages we could extract as human messages. When conversing with chat bots, conversations typically follow a more strict alternating dialogue pattern relative to real conversations.  You can choose to merge message ""runs"" (consecutive messages from the same sender) and select a sender to represent the ""AI"". The fine-tuned LLM will learn to generate these AI messages.  from langchain.chat_loaders.utils import (     map_ai_messages,     merge_chat_runs, )  merged_sessions = merge_chat_runs(chat_sessions) alternating_sessions = list(map_ai_messages(merged_sessions, ""Harry Potter""))  # Now all of Harry Potter's messages will take the AI message class # which maps to the 'assistant' role in OpenAI's training format alternating_sessions[0][""messages""][:3]      [AIMessage(content=""Professor Snape, I was hoping I could speak with you for a moment about something that's been concerning me lately."", additional_kwargs={'sender': 'Harry Potter'}),      HumanMessage(content=""What is it, Potter? I'm quite busy at the moment."", additional_kwargs={'sender': 'Severus Snape'}),      AIMessage(content=""I apologize for the interruption, sir. I'll be brief. I've noticed some strange activity around the school grounds at night. I saw a cloaked figure lurking near the Forbidden Forest last night. I'm worried someone may be plotting something sinister."", additional_kwargs={'sender': 'Harry Potter'})]  Now we can convert to OpenAI format dictionaries​ from langchain.adapters.openai import convert_messages_for_finetuning  training_data = convert_messages_for_finetuning(alternating_sessions) print(f""Prepared {len(training_data)} dialogues for training"")      Prepared 9 dialogues for training  training_data[0][:3]      [{'role': 'assistant',       'content': ""Professor Snape, I was hoping I could speak with you for a moment about something that's been concerning me lately.""},      {'role': 'user',       'content': ""What is it, Potter? I'm quite busy at the moment.""},      {'role': 'assistant',       'content': ""I apologize for the interruption, sir. I'll be brief. I've noticed some strange activity around the school grounds at night. I saw a cloaked figure lurking near the Forbidden Forest last night. I'm worried someone may be plotting something sinister.""}]  OpenAI currently requires at least 10 training examples for a fine-tuning job, though they recommend between 50-100 for most tasks. Since we only have 9 chat sessions, we can subdivide them (optionally with some overlap) so that each training example is comprised of a portion of a whole conversation."
Facebook Messenger | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/chat_loaders/facebook,langchain_docs,"  Facebook chat sessions (1 per person) often span multiple days and conversations, so the long-range dependencies may not be that important to model anyhow.  # Our chat is alternating, we will make each datapoint a group of 8 messages, # with 2 messages overlapping chunk_size = 8 overlap = 2  training_examples = [     conversation_messages[i : i + chunk_size]     for conversation_messages in training_data     for i in range(0, len(conversation_messages) - chunk_size + 1, chunk_size - overlap) ]  len(training_examples)      100  4.

GMail | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/chat_loaders/gmail,langchain_docs,"Main:  #GMail This loader goes over how to load data from GMail. There are many ways you could want to load data from GMail. This loader is currently fairly opinionated in how to do so. The way it does it is it first looks for all messages that you have sent. It then looks for messages where you are responding to a previous email. It then fetches that previous email, and creates a training example of that email, followed by your email.  Note that there are clear limitations here. For example, all examples created are only looking at the previous email for context.  To use:  - Set up a Google Developer Account: Go to the Google Developer Console, create a project, and enable the Gmail API for that project. This will give you a credentials.json file that you'll need later.  - Install the Google Client Library: Run the following command to install the Google Client Library:  pip install --upgrade google-auth google-auth-oauthlib google-auth-httplib2 google-api-python-client  import os.path  from google.auth.transport.requests import Request from google.oauth2.credentials import Credentials from google_auth_oauthlib.flow import InstalledAppFlow  SCOPES = [""https://www.googleapis.com/auth/gmail.readonly""]   creds = None # The file token.json stores the user's access and refresh tokens, and is # created automatically when the authorization flow completes for the first # time. if os.path.exists(""email_token.json""):     creds = Credentials.from_authorized_user_file(""email_token.json"", SCOPES) # If there are no (valid) credentials available, let the user log in. if not creds or not creds.valid:     if creds and creds.expired and creds.refresh_token:         creds.refresh(Request())     else:         flow = InstalledAppFlow.from_client_secrets_file(             # your creds file here.

This class helps convert iMessage conversations to LangChain chat messages.  On MacOS, iMessage stores conversations in a sqlite database at ~/Library/Messages/chat.db (at least for macOS Ventura 13.4). The IMessageChatLoader loads from this database file.  Create the IMessageChatLoader with the file path pointed to chat.db database you'd like to process. Call loader.load() (or loader.lazy_load()) to perform the conversion. Optionally use merge_chat_runs to combine message from the same sender in sequence, and/or map_ai_messages to convert messages from the specified sender to the ""AIMessage"" class. 1. Access Chat DB​ It's likely that your terminal is denied access to ~/Library/Messages. To use this class, you can copy the DB to an accessible directory (e.g., Documents) and load from there. Alternatively (and not recommended), you can grant full disk access for your terminal emulator in System Settings > Security and Privacy > Full Disk Access.  We have created an example database you can use at this linked drive file.  # This uses some example data import requests   def download_drive_file(url: str, output_path: str = ""chat.db"") -> None:     file_id = url.split(""/"")[-2]     download_url = f""https://drive.google.com/uc?export=download&id={file_id}""      response = requests.get(download_url)     if response.status_code != 200:         print(""Failed to download the file."")         return      with open(output_path, ""wb"") as file:         file.write(response.content)         print(f""File {output_path} downloaded."")   url = (     ""https://drive.google.com/file/d/1NebNKqTA2NXApCmeH6mu0unJD2tANZzo/view?usp=sharing"" )  # Download file to chat.db download_drive_file(url)      File chat.db downloaded.  2. Create the Chat Loader​ Provide the loader with the file path to the zip directory. You can optionally specify the user id that maps to an ai message as well an configure whether to merge message runs.  from langchain.chat_loaders.imessage import IMessageChatLoader  loader = IMessageChatLoader(     path=""./chat.db"", )  3. Load messages​ The load() (or lazy_load) methods return a list of ""ChatSessions"" that currently just contain a list of messages per loaded conversation. All messages are mapped to ""HumanMessage"" objects to start.  You can optionally choose to merge message ""runs"" (consecutive messages from the same sender) and select a sender to represent the ""AI"". The fine-tuned LLM will learn to generate these AI messages.  from typing import List  from langchain.chat_loaders.base import ChatSession from langchain.chat_loaders.utils import (     map_ai_messages,     merge_chat_runs, )  raw_messages = loader.lazy_load() # Merge consecutive messages from the same sender into a single message merged_messages = merge_chat_runs(raw_messages) # Convert messages from ""Tortoise"" to AI messages.

This class helps map exported WhatsApp conversations to LangChain chat messages.  The process has three steps:  - Export the chat conversations to computer - Create the WhatsAppChatLoader with the file path pointed to the json file or directory of JSON files - Call loader.load() (or loader.lazy_load()) to perform the conversion. ##1. Create message dump[​](#1-create-message-dump) To make the export of your WhatsApp conversation(s), complete the following steps:  - Open the target conversation - Click the three dots in the top right corner and select ""More"". - Then select ""Export chat"" and choose ""Without media"". An example of the data format for each conversation is below:  whatsapp_chat.txt [8/15/23, 9:12:33 AM] Dr. Feather: ‎Messages and calls are end-to-end encrypted. No one outside of this chat, not even WhatsApp, can read or listen to them. [8/15/23, 9:12:43 AM] Dr. Feather: I spotted a rare Hyacinth Macaw yesterday in the Amazon Rainforest.

Chat models | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/chat/,langchain_docs,"Main:  Skip to main content  🦜️🔗 LangChain  Search CTRLK ComponentsChat models On this page Chat models Features (natively supported)​ All ChatModels implement the Runnable interface, which comes with default implementations of all methods, ie. ainvoke, batch, abatch, stream, astream. This gives all ChatModels basic support for async, streaming and batch, which by default is implemented as below:  Async support defaults to calling the respective sync method in asyncio's default thread pool executor. This lets other async functions in your application make progress while the ChatModel is being executed, by moving this call to a background thread. Streaming support defaults to returning an Iterator (or AsyncIterator in the case of async streaming) of a single value, the final result returned by the underlying ChatModel provider. This obviously doesn't give you token-by-token streaming, which requires native support from the ChatModel provider, but ensures your code that expects an iterator of tokens can work for any of our ChatModel integrations. Batch support defaults to calling the underlying ChatModel in parallel for each input by making use of a thread pool executor (in the sync batch case) or asyncio.gather (in the async batch case). The concurrency can be controlled with the max_concurrency key in RunnableConfig. Each ChatModel integration can optionally provide native implementations to truly enable async or streaming. The table shows, for each integration, which features have been implemented with native support.

I'm just an AI, I don't have a personal identity like humans do, but I'm here to help you with any questions you have.          I'm a large language model, which means I'm trained on a large corpus of text data to generate language outputs that are coherent and natural-sounding. My architecture is based on a transformer model, which is a type of neural network that's particularly well-suited for natural language processing tasks.          As for my parameters, I have a few billion parameters, but I don't have access to the exact number as it's not relevant to my functioning. My training data includes a vast amount of text from various sources, including books, articles, and websites, which I use to learn patterns and relationships in language.          I'm designed to be a helpful tool for a variety of tasks, such as answering questions, providing information, and generating text. I'm constantly learning and improving my abilities through machine learning algorithms and feedback from users like you.          I hope this helps! Is there anything else you'd like to know about me or my capabilities?          ---              meta-llama/Llama-2-7b-chat-hf          Ah, a fellow tech enthusiast! *adjusts glasses* I'm glad to share some technical details about myself. 🤓     Indeed, I'm a transformer model, specifically a BERT-like language model trained on a large corpus of text data. My architecture is based on the transformer framework, which is a type of neural network designed for natural language processing tasks. 🏠     As for the number of parameters, I have approximately 340 million. *winks* That's a pretty hefty number, if I do say so myself! These parameters allow me to learn and represent complex patterns in language, such as syntax, semantics, and more. 🤔     But don't ask me to do math in my head – I'm a language model, not a calculating machine! 😅 My strengths lie in understanding and generating human-like text, so feel free to chat with me anytime you'd like. 💬     Now, do you have any more technical questions for me? Or would you like to engage in a nice chat? 😊          ---              meta-llama/Llama-2-13b-chat-hf          Hello! As a friendly and helpful AI, I'd be happy to share some technical facts about myself.          I am a transformer-based language model, specifically a variant of the BERT (Bidirectional Encoder Representations from Transformers) architecture. BERT was developed by Google in 2018 and has since become one of the most popular and widely-used AI language models.          Here are some technical details about my capabilities:          1. Parameters: I have approximately 340 million parameters, which are the numbers that I use to learn and represent language. This is a relatively large number of parameters compared to some other languages models, but it allows me to learn and understand complex language patterns and relationships.     2. Training: I was trained on a large corpus of text data, including books, articles, and other sources of written content. This training allows me to learn about the structure and conventions of language, as well as the relationships between words and phrases.     3. Architectures: My architecture is based on the transformer model, which is a type of neural network that is particularly well-suited for natural language processing tasks. The transformer model uses self-attention mechanisms to allow the model to ""attend"" to different parts of the input text, allowing it to capture long-range dependencies and contextual relationships.     4. Precision: I am capable of generating text with high precision and accuracy, meaning that I can produce text that is close to human-level quality in terms of grammar, syntax, and coherence.     5. Generative capabilities: In addition to being able to generate text based on prompts and questions, I am also capable of generating text based on a given topic or theme. This allows me to create longer, more coherent pieces of text that are organized around a specific idea or concept.          Overall, I am a powerful and versatile language model that is capable of a wide range of natural language processing tasks. I am constantly learning and improving, and I am here to help answer any questions you may have!          ---          CPU times"

However unlike native OpenAI responses, it does not contain the version of the model, which is set on the deployment in Azure. This makes it tricky to know which version of the model was used to generate the response, which as result can lead to e.g. wrong total cost calculation with OpenAICallbackHandler.  To solve this problem, you can pass model_version parameter to AzureChatOpenAI class, which will be added to the model name in the llm output. This way you can easily distinguish between different versions of the model.  from langchain.callbacks import get_openai_callback  model = AzureChatOpenAI(     openai_api_version=""2023-05-15"",     azure_deployment=""gpt-35-turbo"",  # in Azure, this deployment has version 0613 - input and output tokens are counted separately ) with get_openai_callback() as cb:     model([message])     print(         f""Total Cost (USD): ${format(cb.total_cost, '.6f')}""     )  # without specifying the model version, flat-rate 0.002 USD per 1k input and output tokens is used  We can provide the model version to AzureChatOpenAI constructor. It will get appended to the model name returned by Azure OpenAI and cost will be counted correctly.  model0613 = AzureChatOpenAI(     openai_api_version=""2023-05-15"",     deployment_name=""gpt-35-turbo"",     model_version=""0613"", ) with get_openai_callback() as cb:     model0613([message])     print(f""Total Cost (USD): ${format(cb.total_cost, '.6f')}"")      Total Cost (USD): $0.000044    "
Azure ML Endpoint | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/chat/azureml_chat_endpoint,langchain_docs,"Main:  On this page #Azure ML Endpoint [Azure Machine Learning](https://azure.microsoft.com/en-us/products/machine-learning/) is a platform used to build, train, and deploy machine learning models. Users can explore the types of models to deploy in the Model Catalog, which provides Azure Foundation Models and OpenAI Models. Azure Foundation Models include various open-source models and popular Hugging Face models. Users can also import models of their liking into AzureML.  [Azure Machine Learning Online Endpoints](https://learn.microsoft.com/en-us/azure/machine-learning/concept-endpoints). After you train machine learning models or pipelines, you need to deploy them to production so that others can use them for inference. Inference is the process of applying new input data to the machine learning model or pipeline to generate outputs. While these outputs are typically referred to as ""predictions,"" inferencing can be used to generate outputs for other machine learning tasks, such as classification and clustering. In Azure Machine Learning, you perform inferencing by using endpoints and deployments. Endpoints and Deployments allow you to decouple the interface of your production workload from the implementation that serves it.  This notebook goes over how to use a chat model hosted on an Azure Machine Learning Endpoint.  from langchain.chat_models.azureml_endpoint import AzureMLChatOnlineEndpoint  ##Set up[​](#set-up) To use the wrapper, you must [deploy a model on AzureML](https://learn.microsoft.com/en-us/azure/machine-learning/how-to-use-foundation-models?view=azureml-api-2#deploying-foundation-models-to-endpoints-for-inferencing) and obtain the following parameters:  - endpoint_api_key: The API key provided by the endpoint - endpoint_url: The REST endpoint url provided by the endpoint ##Content Formatter[​](#content-formatter) The content_formatter parameter is a handler class for transforming the request and response of an AzureML endpoint to match with required schema. Since there are a wide range of models in the model catalog, each of which may process data differently from one another, a ContentFormatterBase class is provided to allow users to transform data to their liking.

Simple yet elusive: The Collatz Conjecture is a deceptively simple statement that has proven to be extraordinarily difficult to prove or disprove. Despite its simplicity, the conjecture has eluded some of the brightest minds in mathematics, and it remains one of the most famous open problems in the field.\n2. Wide-ranging implications: The Collatz Conjecture has far-reaching implications for many areas of mathematics, including number theory, algebra, and analysis. A solution to the conjecture could have significant impacts on these fields and potentially lead to new insights and discoveries.\n3. Computational evidence: While the conjecture remains unproven, extensive computational evidence supports its validity. In fact, no counterexample to the conjecture has been found for any starting value up to 2^64 (a number', additional_kwargs={}, example=False)    "

This singularity expanded rapidly, and as it did, it cooled and formed subatomic particles, which eventually coalesced into the first atoms, and later into the stars and galaxies we see today.\n\nThe theory gets its name from the idea that the universe began in a state of incredibly high energy and temperature, and has been expanding and cooling ever since. This expansion is thought to have been driven by a mysterious force known as dark energy, which is thought to be responsible for the accelerating expansion of the universe.\n\nOne of the key predictions of the Big Bang Theory is that the universe should be homogeneous and isotropic on large scales, meaning that it should look the same in all directions and have the same properties everywhere. This prediction has been confirmed by a wealth of observational evidence, including the cosmic microwave background radiation, which is thought to be a remnant of the early universe.\n\nOverall, the Big Bang Theory is a well-established and widely accepted explanation for the origins of the universe, and it has been supported by a vast amount of observational evidence from many fields of science."", additional_kwargs={}, example=False)    "

Several LLM implementations in LangChain can be used as interface to Llama-2 chat models. These include HuggingFaceTextGenInference, LlamaCpp, GPT4All, ..., to mention a few examples.  Llama2Chat is a generic wrapper that implements BaseChatModel and can therefore be used in applications as chat model. Llama2Chat converts a list of chat messages into the required chat prompt format and forwards the formatted prompt as str to the wrapped LLM.  from langchain.chains import LLMChain from langchain.memory import ConversationBufferMemory from langchain_experimental.chat_models import Llama2Chat  For the chat application examples below, we'll use the following chat prompt_template:  from langchain.prompts.chat import (     ChatPromptTemplate,     HumanMessagePromptTemplate,     MessagesPlaceholder, ) from langchain.schema import SystemMessage  template_messages = [     SystemMessage(content=""You are a helpful assistant.""),     MessagesPlaceholder(variable_name=""chat_history""),     HumanMessagePromptTemplate.from_template(""{text}""), ] prompt_template = ChatPromptTemplate.from_messages(template_messages)  Chat with Llama-2 via HuggingFaceTextGenInference LLM​ A HuggingFaceTextGenInference LLM encapsulates access to a text-generation-inference server. In the following example, the inference server serves a meta-llama/Llama-2-13b-chat-hf model. It can be started locally with:  docker run \   --rm \   --gpus all \   --ipc=host \   -p 8080:80 \   -v ~/.cache/huggingface/hub:/data \   -e HF_API_TOKEN=${HF_API_TOKEN} \   ghcr.io/huggingface/text-generation-inference:0.9 \   --hostname 0.0.0.0 \   --model-id meta-llama/Llama-2-13b-chat-hf \   --quantize bitsandbytes \   --num-shard 4  This works on a machine with 4 x RTX 3080ti cards, for example. Adjust the --num_shard value to the number of GPUs available. The HF_API_TOKEN environment variable holds the Hugging Face API token.  # !pip3 install text-generation  Create a HuggingFaceTextGenInference instance that connects to the local inference server and wrap it into Llama2Chat.  from langchain.llms import HuggingFaceTextGenInference  llm = HuggingFaceTextGenInference(     inference_server_url=""http://127.0.0.1:8080/"",     max_new_tokens=512,     top_k=50,     temperature=0.1,     repetition_penalty=1.03, )  model = Llama2Chat(llm=llm)  Then you are ready to use the chat model together with prompt_template and conversation memory in an LLMChain.  memory = ConversationBufferMemory(memory_key=""chat_history"", return_messages=True) chain = LLMChain(llm=model, prompt=prompt_template, memory=memory)  print(     chain.run(         text=""What can I see in Vienna?

St. Stephen's Cathedral (Stephansdom) is one of the most recognizable landmarks in Vienna and a must-see attraction for visitors. This stunning Gothic cathedral is located in the heart of the city and is known for its intricate stone carvings, colorful stained glass windows, and impressive dome.          The cathedral was built in the 12th century and has been the site of many important events throughout history, including the coronation of Holy Roman emperors and the funeral of Mozart. Today, it is still an active place of worship and offers guided tours, concerts, and special events.

Ollama | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/chat/ollama,langchain_docs,"Main:  On this page #Ollama [Ollama](https://ollama.ai/) allows you to run open-source large language models, such as LLaMA2, locally.  Ollama bundles model weights, configuration, and data into a single package, defined by a Modelfile.  It optimizes setup and configuration details, including GPU usage.  For a complete list of supported models and model variants, see the [Ollama model library](https://ollama.ai/library).  ##Setup[​](#setup) First, follow [these instructions](https://github.com/jmorganca/ollama) to set up and run a local Ollama instance:  - [Download](https://ollama.ai/download) - Fetch a model via ollama pull <model family> - e.g., for Llama-7b: ollama pull llama2 - This will download the most basic version of the model (e.g., minimum # parameters and 4-bit quantization) - On Mac, it will download to: ~/.ollama/models/manifests/registry.ollama.ai/library/<model family>/latest  - And we can specify a particular version, e.g., for ollama pull vicuna:13b-v1.5-16k-q4_0 - The file is here with the model version in place of latest ~/.ollama/models/manifests/registry.ollama.ai/library/vicuna/13b-v1.5-16k-q4_0  You can easily access models in a few ways:  1/ if the app is running:  - All of your local models are automatically served on localhost:11434 - Select your model when setting llm = Ollama(..., model=""<model family>:<version>"") - If you set llm = Ollama(..., model=""<model family"") withoout a version it will simply look for latest 2/ if building from source or just running the binary:  - Then you must run ollama serve - All of your local models are automatically served on localhost:11434 - Then, select as shown above ##Usage[​](#usage) You can see a full list of supported parameters on the [API reference page](https://api.python.langchain.com/en/latest/llms/langchain.llms.ollama.Ollama.html).  If you are using a LLaMA chat model (e.g., ollama pull llama2:7b-chat) then you can use the ChatOllama interface.

Early Beginnings (1950s-1960s): The term ""Artificial Intelligence"" was coined in 1956 by computer scientist John McCarthy. However, the concept of creating machines that can think and learn like humans dates back to ancient times. In the 1950s and 1960s, researchers began exploring the possibilities of AI using simple algorithms and machine learning techniques.     2. Rule-Based Systems (1970s-1980s): In the 1970s and 1980s, AI research focused on developing rule-based systems, which use predefined rules to reason and make decisions. This led to the development of expert systems, which were designed to mimic the decision-making abilities of human experts in specific domains.     3. Machine Learning (1980s-1990s): The 1980s saw a shift towards machine learning, which enables machines to learn from data without being explicitly programmed. This led to the development of algorithms such as decision trees, neural networks, and support vector machines.     4. Deep Learning (2000s-present): In the early 2000s, deep learning emerged as a subfield of machine learning, focusing on neural networks with multiple layers. These networks can learn complex representations of data, leading to breakthroughs in image and speech recognition, natural language processing, and other areas.     5. Natural Language Processing (NLP) (1980s-present): NLP has been an active area of research since the 1980s, with a focus on developing algorithms that can understand and generate human language. This has led to applications such as chatbots, voice assistants, and language translation systems.     6. Robotics (1970s-present): The development of robotics has been closely tied to AI research, with a focus on creating machines that can perform tasks that typically require human intelligence, such as manipulation and locomotion.     7. Computer Vision (1980s-present): Computer vision has been an active area of research since the 1980s, with a focus on enabling machines to interpret and understand visual data from the world around us. This has led to applications such as image recognition, object detection, and autonomous driving.     8. Ethics and Society (1990s-present): As AI technology has become more advanced and integrated into various aspects of society, there has been a growing concern about the ethical implications of AI. This includes issues related to privacy, bias, and job displacement.     9. Reinforcement Learning (2000s-present): Reinforcement learning is a subfield of machine learning that involves training machines to make decisions based on feedback from their environment. This has led to breakthroughs in areas such as game playing, robotics, and autonomous driving.     10. Generative Models (2010s-present): Generative models are a class of AI algorithms that can generate new data that is similar to a given dataset. This has led to applications such as image synthesis, music generation, and language creation.          These are just a few of the many developments in the history of AI.

Ollama Functions | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/chat/ollama_functions,langchain_docs,"Main:  On this page #Ollama Functions This notebook shows how to use an experimental wrapper around Ollama that gives it the same API as OpenAI Functions.  Note that more powerful and capable models will perform better with complex schema and/or multiple functions. The examples below use Mistral. For a complete list of supported models and model variants, see the [Ollama model library](https://ollama.ai/library).  ##Setup[​](#setup) Follow [these instructions](https://github.com/jmorganca/ollama) to set up and run a local Ollama instance.  ##Usage[​](#usage) You can initialize OllamaFunctions in a similar way to how you'd initialize a standard ChatOllama instance:  from langchain_experimental.llms.ollama_functions import OllamaFunctions  model = OllamaFunctions(model=""mistral"")  You can then bind functions defined with JSON Schema parameters and a function_call parameter to force the model to call the given function:  model = model.bind(     functions=[         {             ""name"": ""get_current_weather"",             ""description"": ""Get the current weather in a given location"",             ""parameters"": {                 ""type"": ""object"",                 ""properties"": {                     ""location"": {                         ""type"": ""string"",                         ""description"": ""The city and state, "" ""e.g. San Francisco, CA"",                     },                     ""unit"": {                         ""type"": ""string"",                         ""enum"": [""celsius"", ""fahrenheit""],                     },                 },                 ""required"": [""location""],             },         }     ],     function_call={""name"": ""get_current_weather""}, )  Calling a function with this model then results in JSON output matching the provided schema:  from langchain.schema import HumanMessage  model.invoke(""what is the weather in Boston?"")

It has the largest catalog of ELT connectors to data warehouses and databases.  A lot of source connectors are implemented using the [Airbyte CDK](https://docs.airbyte.com/connector-development/cdk-python/). This loader allows to run any of these connectors and return the data as documents.  ##Installation[​](#installation) First, you need to install the airbyte-cdk python package.  #!pip install airbyte-cdk  Then, either install an existing connector from the [Airbyte Github repository](https://github.com/airbytehq/airbyte/tree/master/airbyte-integrations/connectors) or create your own connector using the [Airbyte CDK](https://docs.airbyte.io/connector-development/connector-development).  For example, to install the Github connector, run  #!pip install ""source_github@git+https://github.com/airbytehq/airbyte.git@master#subdirectory=airbyte-integrations/connectors/source-github""  Some sources are also published as regular packages on PyPI  ##Example[​](#example) Now you can create an AirbyteCDKLoader based on the imported source. It takes a config object that's passed to the connector. You also have to pick the stream you want to retrieve records from by name (stream_name). Check the connectors documentation page and spec definition for more information on the config object and available streams. For the Github connectors these are:  - [https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/connectors/source-github/source_github/spec.json](https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/connectors/source-github/source_github/spec.json). - [https://docs.airbyte.com/integrations/sources/github/](https://docs.airbyte.com/integrations/sources/github/) from langchain.document_loaders.airbyte import AirbyteCDKLoader from source_github.source import SourceGithub  # plug in your own source here  config = {     # your github configuration     ""credentials"": {""api_url"": ""api.github.com"", ""personal_access_token"": ""<token>""},     ""repository"": ""<repo>"",     ""start_date"": ""<date from which to start retrieving records from in ISO format, e.g. 2020-10-20T00:00:00Z>"", }  issues_loader = AirbyteCDKLoader(     source_class=SourceGithub, config=config, stream_name=""issues"" )  Now you can load documents the usual way  docs = issues_loader.load()  As load returns a list, it will block until all documents are loaded. To have better control over this process, you can also you the lazy_load method which returns an iterator instead:  docs_iterator = issues_loader.lazy_load()  Keep in mind that by default the page content is empty and the metadata object contains all the information from the record. To create documents in a different, pass in a record_handler function when creating the loader:  from langchain.docstore.document import Document   def handle_record(record, id):     return Document(         page_content=record.data[""title""] + ""\n"" + (record.data[""body""] or """"),         metadata=record.data,     )   issues_loader = AirbyteCDKLoader(     source_class=SourceGithub,     config=config,     stream_name=""issues"",     record_handler=handle_record, )  docs = issues_loader.load()  ##Incremental loads[​](#incremental-loads) Some streams allow incremental loading, this means the source keeps track of synced records and won't load them again. This is useful for sources that have a high volume of data and are updated frequently.  To take advantage of this, store the last_state property of the loader and pass it in when creating the loader again. This will ensure that only new records are loaded.  last_state = issues_loader.last_state  # store safely  incremental_issue_loader = AirbyteCDKLoader(     source_class=SourceGithub, config=config, stream_name=""issues"", state=last_state )  new_docs = incremental_issue_loader.load()    "

Airbyte Zendesk Support | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/airbyte_zendesk_support,langchain_docs,"Main:  On this page #Airbyte Zendesk Support [Airbyte](https://github.com/airbytehq/airbyte) is a data integration platform for ELT pipelines from APIs, databases & files to warehouses & lakes. It has the largest catalog of ELT connectors to data warehouses and databases.  This loader exposes the Zendesk Support connector as a document loader, allowing you to load various objects as documents.  ##Installation[​](#installation) First, you need to install the airbyte-source-zendesk-support python package.  #!pip install airbyte-source-zendesk-support  ##Example[​](#example) Check out the [Airbyte documentation page](https://docs.airbyte.com/integrations/sources/zendesk-support/) for details about how to configure the reader. The JSON schema the config object should adhere to can be found on Github: [https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/connectors/source-zendesk-support/source_zendesk_support/spec.json](https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/connectors/source-zendesk-support/source_zendesk_support/spec.json).  The general shape looks like this:  {   ""subdomain"": ""<your zendesk subdomain>"",   ""start_date"": ""<date from which to start retrieving records from in ISO format, e.g. 2020-10-20T00:00:00Z>"",   ""credentials"": {     ""credentials"": ""api_token"",     ""email"": ""<your email>"",     ""api_token"": ""<your api token>""   } }  By default all fields are stored as metadata in the documents and the text is set to an empty string. Construct the text of the document by transforming the documents returned by the reader.  from langchain.document_loaders.airbyte import AirbyteZendeskSupportLoader  config = {     # your zendesk-support configuration }  loader = AirbyteZendeskSupportLoader(     config=config, stream_name=""tickets"" )  # check the documentation linked above for a list of all streams  Now you can load documents the usual way  docs = loader.load()  As load returns a list, it will block until all documents are loaded. To have better control over this process, you can also you the lazy_load method which returns an iterator instead:  docs_iterator = loader.lazy_load()  Keep in mind that by default the page content is empty and the metadata object contains all the information from the record. To create documents in a different, pass in a record_handler function when creating the loader:  from langchain.docstore.document import Document   def handle_record(record, id):     return Document(page_content=record.data[""title""], metadata=record.data)   loader = AirbyteZendeskSupportLoader(     config=config, record_handler=handle_record, stream_name=""tickets"" ) docs = loader.load()  ##Incremental loads[​](#incremental-loads) Some streams allow incremental loading, this means the source keeps track of synced records and won't load them again. This is useful for sources that have a high volume of data and are updated frequently.  To take advantage of this, store the last_state property of the loader and pass it in when creating the loader again. This will ensure that only new records are loaded.  last_state = loader.last_state  # store safely  incremental_loader = AirbyteZendeskSupportLoader(     config=config, stream_name=""tickets"", state=last_state )  new_docs = incremental_loader.load()    "

AssemblyAI Audio Transcripts | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/assemblyai,langchain_docs,"Main:  On this page #AssemblyAI Audio Transcripts The AssemblyAIAudioTranscriptLoader allows to transcribe audio files with the [AssemblyAI API](https://www.assemblyai.com) and loads the transcribed text into documents.  To use it, you should have the assemblyai python package installed, and the environment variable ASSEMBLYAI_API_KEY set with your API key. Alternatively, the API key can also be passed as an argument.  More info about AssemblyAI:  - [Website](https://www.assemblyai.com/) - [Get a Free API key](https://www.assemblyai.com/dashboard/signup) - [AssemblyAI API Docs](https://www.assemblyai.com/docs) ##Installation[​](#installation) First, you need to install the assemblyai python package.  You can find more info about it inside the [assemblyai-python-sdk GitHub repo](https://github.com/AssemblyAI/assemblyai-python-sdk).  #!pip install assemblyai  ##Example[​](#example) The AssemblyAIAudioTranscriptLoader needs at least the file_path argument. Audio files can be specified as an URL or a local file path.  from langchain.document_loaders import AssemblyAIAudioTranscriptLoader  audio_file = ""https://storage.googleapis.com/aai-docs-samples/nbc.mp3"" # or a local file path: audio_file = ""./nbc.mp3""  loader = AssemblyAIAudioTranscriptLoader(file_path=audio_file)  docs = loader.load()  Note: Calling loader.load() blocks until the transcription is finished.  The transcribed text is available in the page_content:  docs[0].page_content  ""Load time, a new president and new congressional makeup. Same old ...""  The metadata contains the full JSON response with more meta information:  docs[0].metadata  {'language_code': <LanguageCode.en_us: 'en_us'>,  'audio_url': 'https://storage.googleapis.com/aai-docs-samples/nbc.mp3',  'punctuate': True,  'format_text': True,   ... }  ##Transcript Formats[​](#transcript-formats) You can specify the transcript_format argument for different formats.  Depending on the format, one or more documents are returned. These are the different TranscriptFormat options:  - TEXT: One document with the transcription text - SENTENCES: Multiple documents, splits the transcription by each sentence - PARAGRAPHS: Multiple documents, splits the transcription by each paragraph - SUBTITLES_SRT: One document with the transcript exported in SRT subtitles format - SUBTITLES_VTT: One document with the transcript exported in VTT subtitles format from langchain.document_loaders.assemblyai import TranscriptFormat  loader = AssemblyAIAudioTranscriptLoader(     file_path=""./your_file.mp3"",     transcript_format=TranscriptFormat.SENTENCES, )  docs = loader.load()  ##Transcription Config[​](#transcription-config) You can also specify the config argument to use different audio intelligence models.  Visit the [AssemblyAI API Documentation](https://www.assemblyai.com/docs) to get an overview of all available models!  import assemblyai as aai  config = aai.TranscriptionConfig(     speaker_labels=True, auto_chapters=True, entity_detection=True )  loader = AssemblyAIAudioTranscriptLoader(file_path=""./your_file.mp3"", config=config)  ##Pass the API Key as argument[​](#pass-the-api-key-as-argument) Next to setting the API key as environment variable ASSEMBLYAI_API_KEY, it is also possible to pass it as argument.  loader = AssemblyAIAudioTranscriptLoader(     file_path=""./your_file.mp3"", api_key=""YOUR_KEY"" )    "

Confluence | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/confluence,langchain_docs,"Main:  On this page #Confluence [Confluence](https://www.atlassian.com/software/confluence) is a wiki collaboration platform that saves and organizes all of the project-related material. Confluence is a knowledge base that primarily handles content management activities.  A loader for Confluence pages.  This currently supports username/api_key, Oauth2 login. Additionally, on-prem installations also support token authentication.  Specify a list page_id-s and/or space_key to load in the corresponding pages into Document objects, if both are specified the union of both sets will be returned.  You can also specify a boolean include_attachments to include attachments, this is set to False by default, if set to True all attachments will be downloaded and ConfluenceReader will extract the text from the attachments and add it to the Document object. Currently supported attachment types are: PDF, PNG, JPEG/JPG, SVG, Word and Excel.  Hint: space_key and page_id can both be found in the URL of a page in Confluence - [https://yoursite.atlassian.com/wiki/spaces/](https://yoursite.atlassian.com/wiki/spaces/)<space_key>/pages/<page_id>  Before using ConfluenceLoader make sure you have the latest version of the atlassian-python-api package installed:  #!pip install atlassian-python-api  ##Examples[​](#examples) ###Username and Password or Username and API Token (Atlassian Cloud only)[​](#username-and-password-or-username-and-api-token-atlassian-cloud-only) This example authenticates using either a username and password or, if you're connecting to an Atlassian Cloud hosted version of Confluence, a username and an API Token. You can generate an API token at: [https://id.atlassian.com/manage-profile/security/api-tokens](https://id.atlassian.com/manage-profile/security/api-tokens).  The limit parameter specifies how many documents will be retrieved in a single call, not how many documents will be retrieved in total. By default the code will return up to 1000 documents in 50 documents batches. To control the total number of documents use the max_pages parameter. Plese note the maximum value for the limit parameter in the atlassian-python-api package is currently 100.  from langchain.document_loaders import ConfluenceLoader  loader = ConfluenceLoader(     url=""https://yoursite.atlassian.com/wiki"", username=""me"", api_key=""12345"" ) documents = loader.load(space_key=""SPACE"", include_attachments=True, limit=50)  ###Personal Access Token (Server/On-Prem only)[​](#personal-access-token-serveron-prem-only) This method is valid for the Data Center/Server on-prem edition only. For more information on how to generate a Personal Access Token (PAT) check the official Confluence documentation at: [https://confluence.atlassian.com/enterprise/using-personal-access-tokens-1026032365.html](https://confluence.atlassian.com/enterprise/using-personal-access-tokens-1026032365.html). When using a PAT you provide only the token value, you cannot provide a username. Please note that ConfluenceLoader will run under the permissions of the user that generated the PAT and will only be able to load documents for which said user has access to.  from langchain.document_loaders import ConfluenceLoader  loader = ConfluenceLoader(url=""https://yoursite.atlassian.com/wiki"", token=""12345"") documents = loader.load(     space_key=""SPACE"", include_attachments=True, limit=50, max_pages=50 )    "

Annotations are encoded in plain text files (UTF-8, normalized to NFC, using only the LF character as line break, including an LF character at the end of file) with three types of lines:  - Word lines containing the annotation of a word/token in 10 fields separated by single tab characters; see below. - Blank lines marking sentence boundaries. - Comment lines starting with hash (#). This is an example of how to load a file in [CoNLL-U](https://universaldependencies.org/format.html) format. The whole file is treated as one document. The example data (conllu.conllu) is based on one of the standard UD/CoNLL-U examples.  from langchain.document_loaders import CoNLLULoader  loader = CoNLLULoader(""example_data/conllu.conllu"")  document = loader.load()  document      [Document(page_content='They buy and sell books.', metadata={'source': 'example_data/conllu.conllu'})]    "

Cube Semantic Layer | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/cube_semantic,langchain_docs,"Main:  On this page #Cube Semantic Layer This notebook demonstrates the process of retrieving Cube's data model metadata in a format suitable for passing to LLMs as embeddings, thereby enhancing contextual information.  ###About Cube[​](#about-cube) [Cube](https://cube.dev/) is the Semantic Layer for building data apps. It helps data engineers and application developers access data from modern data stores, organize it into consistent definitions, and deliver it to every application.  Cube’s data model provides structure and definitions that are used as a context for LLM to understand data and generate correct queries. LLM doesn’t need to navigate complex joins and metrics calculations because Cube abstracts those and provides a simple interface that operates on the business-level terminology, instead of SQL table and column names. This simplification helps LLM to be less error-prone and avoid hallucinations.  ###Example[​](#example) Input arguments (mandatory)  Cube Semantic Loader requires 2 arguments:  - cube_api_url: The URL of your Cube's deployment REST API. Please refer to the [Cube documentation](https://cube.dev/docs/http-api/rest#configuration-base-path) for more information on configuring the base path.  - cube_api_token: The authentication token generated based on your Cube's API secret. Please refer to the [Cube documentation](https://cube.dev/docs/security#generating-json-web-tokens-jwt) for instructions on generating JSON Web Tokens (JWT).  Input arguments (optional)  - load_dimension_values: Whether to load dimension values for every string dimension or not.  - dimension_values_limit: Maximum number of dimension values to load.  - dimension_values_max_retries: Maximum number of retries to load dimension values.  - dimension_values_retry_delay: Delay between retries to load dimension values.  import jwt from langchain.document_loaders import CubeSemanticLoader  api_url = ""https://api-example.gcp-us-central1.cubecloudapp.dev/cubejs-api/v1/meta"" cubejs_api_secret = ""api-secret-here"" security_context = {} # Read more about security context here: https://cube.dev/docs/security api_token = jwt.encode(security_context, cubejs_api_secret, algorithm=""HS256"")  loader = CubeSemanticLoader(api_url, api_token)  documents = loader.load()  Returns a list of documents with the following attributes:  - page_content - metadata - table_name - column_name - column_data_type - column_title - column_description - column_values - cube_data_obj_type # Given string containing page content page_content = ""Users View City, None""  # Given dictionary containing metadata metadata = {     ""table_name"": ""users_view"",     ""column_name"": ""users_view.city"",     ""column_data_type"": ""string"",     ""column_title"": ""Users View City"",     ""column_description"": ""None"",     ""column_member_type"": ""dimension"",     ""column_values"": [         ""Austin"",         ""Chicago"",         ""Los Angeles"",         ""Mountain View"",         ""New York"",         ""Palo Alto"",         ""San Francisco"",         ""Seattle"",     ],     ""cube_data_obj_type"": ""view"", }    "

We believe that the most powerful and differentiated applications will not only call out to a language model via an API, but will also:\nBe data-aware: connect a language model to other sources of data\nBe agentic: allow a language model to interact with its environment\nThe LangChain framework is designed with the above principles in mind.\nThis is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see here. For the JavaScript documentation, see here.\nGetting Started\nCheckout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.\nGetting Started Documentation\nModules\nThere are several main modules that LangChain provides support for. For each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides. These modules are, in increasing order of complexity:\nModels: The various model types and model integrations LangChain supports.\nPrompts: This includes prompt management, prompt optimization, and prompt serialization.\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\nChains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\nUse Cases\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\nPersonal Assistants: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.\nQuestion Answering: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.\nInteracting with APIs: Enabling LLMs to interact with APIs is extremely powerful in order to give them more up-to-date information and allow them to take actions.\nExtraction: Extract structured information from text.\nSummarization: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.\nEvaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.\nReference Docs\nAll of LangChain’s reference documentation, in one place. Full documentation on all methods, classes, installation methods, and integration setups for LangChain.\nReference Documentation\nLangChain Ecosystem\nGuides for how other companies/products can be used with LangChain\nLangChain Ecosystem\nAdditional Resources\nAdditional collection of resources we think may be useful as you develop your application!\nLangChainHub: The LangChainHub is a place to share and explore other prompts, chains, and agents.\nGlossary: A glossary of all related terms, papers, methods, etc. Whether implemented in LangChain or not!\nGallery: A collection of our favorite projects that use LangChain. Useful for finding inspiration or seeing how things were done in other applications.\nDeployments: A collection of instructions, code snippets, and template repositories for deploying LangChain apps.\nTracing: A guide on using tracing in LangChain to visualize the execution of chains and agents.\nModel Laboratory: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.\nDiscord: Join us on our Discord to discuss all things LangChain!\nProduction Support: As you move your LangChains into production, we’d love to offer more comprehensive support.

It provides the advantages of using this system over alternative data loaders.  Prerequisites​ Install necessary python packages. Grab an access token for your workspace, and make sure it is set as the DOCUGAMI_API_KEY environment variable. Grab some docset and document IDs for your processed documents, as described here: https://help.docugami.com/home/docugami-api # You need the dgml-utils package to use the DocugamiLoader (run pip install directly without ""poetry run"" if you are not using poetry) poetry run pip install dgml-utils==0.3.0 --upgrade --quiet  Quick start​ Create a Docugami workspace (free trials available) Add your documents (PDF, DOCX or DOC) and allow Docugami to ingest and cluster them into sets of similar documents, e.g. NDAs, Lease Agreements, and Service Agreements. There is no fixed set of document types supported by the system, the clusters created depend on your particular documents, and you can change the docset assignments later. Create an access token via the Developer Playground for your workspace. Detailed instructions Explore the Docugami API to get a list of your processed docset IDs, or just the document IDs for a particular docset. Use the DocugamiLoader as detailed below, to get rich semantic chunks for your documents. Optionally, build and publish one or more reports or abstracts. This helps Docugami improve the semantic XML with better tags based on your preferences, which are then added to the DocugamiLoader output as metadata. Use techniques like self-querying retriever to do high accuracy Document QA. Advantages vs Other Chunking Techniques​ Appropriate chunking of your documents is critical for retrieval from documents. Many chunking techniques exist, including simple ones that rely on whitespace and recursive chunk splitting based on character length. Docugami offers a different approach:  Intelligent Chunking: Docugami breaks down every document into a hierarchical semantic XML tree of chunks of varying sizes, from single words or numerical values to entire sections. These chunks follow the semantic contours of the document, providing a more meaningful representation than arbitrary length or simple whitespace-based chunking. Semantic Annotations: Chunks are annotated with semantic tags that are coherent across the document set, facilitating consistent hierarchical queries across multiple documents, even if they are written and formatted differently. For example, in set of lease agreements, you can easily identify key provisions like the Landlord, Tenant, or Renewal Date, as well as more complex information such as the wording of any sub-lease provision or whether a specific jurisdiction has an exception section within a Termination Clause. Structured Representation: In addition, the XML tree indicates the structural contours of every document, using attributes denoting headings, paragraphs, lists, tables, and other common elements, and does that consistently across all supported document formats, such as scanned PDFs or DOCX files. It appropriately handles long-form document characteristics like page headers/footers or multi-column flows for clean text extraction. Additional Metadata: Chunks are also annotated with additional metadata, if a user has been using Docugami. This additional metadata can be used for high-accuracy Document QA without context window restrictions. See detailed code walk-through below. import os  from langchain.document_loaders import DocugamiLoader  Load Documents​ If the DOCUGAMI_API_KEY environment variable is set, there is no need to pass it in to the loader explicitly otherwise you can pass it in as the access_token parameter.  DOCUGAMI_API_KEY = os.environ.get(""DOCUGAMI_API_KEY"")  docset_id = ""26xpy3aes7xp"" document_ids = [""d7jqdzcj50sj"", ""cgd1eacfkchw""]  # To load all docs in the given docset ID, just don't provide document_ids loader = DocugamiLoader(docset_id=docset_id, document_ids=document_ids) chunks = loader.load() len(chunks)      120  The metadata for each Document (really, a chunk of an actual PDF, DOC or DOCX) contains some useful additional information:  id and source: ID and Name of the file (PDF, DOC or DOCX) the chunk is sourced from within Docugami. xpath: XPath inside the XML representation of the document, for the chunk. Useful for source citations directly to the actual chunk inside the document XML. structure: Structural attributes of the chunk, e.g. h1, h2, div, table, td, etc. Useful to filter out certain kinds of chunks if needed by the caller. tag: Semantic tag for the chunk, using various generative and extractive techniques. More details here: https://github.com/docugami/DFM-benchmarks You can control chunking behavior by setting the following properties on the DocugamiLoader instance:  You can set min and max chunk size, which the system tries to adhere to with minimal truncation. You can set loader.min_text_length and loader.max_text_length to control these. By default, only the text for chunks is returned. However, Docugami's XML knowledge graph has additional rich information including semantic tags for entities inside the chunk. Set loader.include_xml_tags = True if you want the additional xml metadata on the returned chunks. In addition, you can set loader.parent_hierarchy_levels if you want Docugami to return parent chunks in the chunks it returns. The child chunks point to the parent chunks via the loader.parent_id_key value. This is useful e.g. with the MultiVector Retriever for small-to-big retrieval. See detailed example later in this notebook. loader.min_text_length = 64 loader.include_xml_tags = True chunks = loader.load()  for chunk in chunks[:5]:     print(chunk)      page_content='MASTER SERVICES AGREEMENT\n <ThisServicesAgreement> This Services Agreement (the “Agreement”) sets forth terms under which <Comp"

There are many great tutorials on how to do this, e.g. this one. We can just use the same code, but use the DocugamiLoader for better chunking, instead of loading text or PDF files directly with basic splitting techniques.  poetry run pip install --upgrade openai tiktoken chromadb hnswlib --quiet  # For this example, we already have a processed docset for a set of lease documents loader = DocugamiLoader(docset_id=""zo954yqy53wp"") chunks = loader.load()  # strip semantic metadata intentionally, to test how things work without semantic metadata for chunk in chunks:     stripped_metadata = chunk.metadata.copy()     for key in chunk.metadata:         if key not in [""name"", ""xpath"", ""id"", ""structure""]:             # remove semantic metadata             del stripped_metadata[key]     chunk.metadata = stripped_metadata  print(len(chunks))      4674  The documents returned by the loader are already split, so we don't need to use a text splitter. Optionally, we can use the metadata on each document, for example the structure or tag attributes, to do any post-processing we want.  We will just use the output of the DocugamiLoader as-is to set up a retrieval QA chain the usual way.  from langchain.chains import RetrievalQA from langchain.embeddings import OpenAIEmbeddings from langchain.llms.openai import OpenAI from langchain.vectorstores.chroma import Chroma  embedding = OpenAIEmbeddings() vectordb = Chroma.from_documents(documents=chunks, embedding=embedding) retriever = vectordb.as_retriever() qa_chain = RetrievalQA.from_chain_type(     llm=OpenAI(), chain_type=""stuff"", retriever=retriever, return_source_documents=True )  # Try out the retriever with an example query qa_chain(""What can tenants do with signage on their properties?"")      {'query': 'What can tenants do with signage on their properties?',      'result': ' Tenants can place or attach signage (digital or otherwise) to their property after receiving written permission from the landlord, which permission shall not be unreasonably withheld.

Typical chunking techniques, even with overlap, will struggle with providing the LLM sufficent context to answer such questions. With upcoming very large context LLMs, it may be possible to stuff a lot of tokens, perhaps even entire documents, inside the context but this will still hit limits at some point with very long documents, or a lot of documents.  For example, if we ask a more complex question that requires the LLM to draw on chunks from different parts of the document, even OpenAI's powerful LLM is unable to answer correctly.  chain_response = qa_chain(""What is rentable area for the property owned by DHA Group?"") chain_response[""result""]  # correct answer should be 13,500 sq ft      "" I don't know.""  chain_response[""source_documents""]      [Document(page_content='1.6 Rentable Area of the Premises.', metadata={'id': '5b39a1ae84d51682328dca1467be211f', 'name': 'Sample Commercial Leases/Shorebucks LLC_WA.pdf', 'structure': 'lim h1', 'xpath': '/docset:OFFICELEASE-section/docset:OFFICELEASE-section/docset:OFFICELEASE/docset:WITNESSETH-section/docset:WITNESSETH/dg:chunk/dg:chunk/docset:BasicLeaseInformation/docset:BASICLEASEINFORMATIONANDDEFINEDTERMS-section/docset:BASICLEASEINFORMATIONANDDEFINEDTERMS/docset:CatalystGroup/dg:chunk[6]/dg:chunk'}),      Document(page_content='1.6 Rentable Area of the Premises.', metadata={'id': '5b39a1ae84d51682328dca1467be211f', 'name': 'Sample Commercial Leases/Shorebucks LLC_AZ.pdf', 'structure': 'lim h1', 'xpath': '/docset:OFFICELEASE-section/docset:OFFICELEASE-section/docset:WITNESSETH-section/docset:WITNESSETH/dg:chunk/dg:chunk/docset:BasicLeaseInformation/docset:BASICLEASEINFORMATIONANDDEFINEDTERMS-section/docset:BASICLEASEINFORMATIONANDDEFINEDTERMS/docset:MenloGroup/dg:chunk[6]/dg:chunk'}),      Document(page_content='1.6 Rentable Area of the Premises.', metadata={'id': '5b39a1ae84d51682328dca1467be211f', 'name': 'Sample Commercial Leases/Shorebucks LLC_FL.pdf', 'structure': 'lim h1', 'xpath': '/docset:OFFICELEASE-section/docset:OFFICELEASE/docset:WITNESSETH-section/docset:WITNESSETH/docset:Florida-section/docset:Florida/docset:Shorebucks/dg:chunk[5]/dg:chunk'}),      Document(page_content='1.6 Rentable Area of the Premises.', metadata={'id': '5b39a1ae84d51682328dca1467be211f', 'name': 'Sample Commercial Leases/Shorebucks LLC_TX.pdf', 'structure': 'lim h1', 'xpath': '/docset:OFFICELEASE-section/docset:OFFICELEASE/docset:WITNESSETH-section/docset:WITNESSETH/dg:chunk/dg:chunk/docset:BasicLeaseInformation/docset:BASICLEASEINFORMATIONANDDEFINEDTERMS-section/docset:BASICLEASEINFORMATIONANDDEFINEDTERMS/docset:LandmarkLlc/dg:chunk[6]/dg:chunk'})]  At first glance the answer may seem reasonable, but it is incorrect. If you review the source chunks carefully for this answer, you will see that the chunking of the document did not end up putting the Landlord name and the rentable area in the same context, and produced irrelevant chunks therefore the answer is incorrect (should be 13,500 sq ft)  Docugami can help here. Chunks are annotated with additional metadata created using different techniques if a user has been using Docugami. More technical approaches will be added later.  Specifically, let's ask Docugami to return XML tags on its output, as well as additional metadata:  loader = DocugamiLoader(docset_id=""zo954yqy53wp"") loader.include_xml_tags = (     True  # for additional semantics from the Docugami knowledge graph ) chunks = loader.load() print(chunks[0].metadata)      {'xpath': '/docset:OFFICELEASE-section/dg:chunk', 'id': '47297e277e556f3ce8b570047304560b', 'name': 'Sample Commercial Leases/Shorebucks LLC_AZ.pdf', 'source': 'Sample Commercial Leases/Sh"

The resulting source chunks are all relevant to this landlord, and this improves answer accuracy even though the landlord is not directly mentioned in the specific chunk that contains the correct answer.  Advanced Topic: Small-to-Big Retrieval with Document Knowledge Graph Hierarchy Documents are inherently semi-structured and the DocugamiLoader is able to navigate the semantic and structural contours of the document to provide parent chunk references on the chunks it returns. This is useful e.g. with the MultiVector Retriever for small-to-big retrieval.

LangChain provides a large collection of common utils to use in your application.\\nChains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\\nChat: Chat models are a variation on Language Models that expose a different API - rather than working with raw text, they work with messages. LangChain provides a standard interface for working with them and doing all the same things as above.\\n\\n\\n\\n\\n\\nUse Cases#\\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\\n\\nAgents: Agents are systems that use a language model to interact with other tools. These can be used to do more grounded question/answering, interact with APIs, or even take actions.\\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\\nData Augmented Generation: Data Augmented Generation involves specific types of chains that first interact with an external datasource to fetch data to use in the generation step. Examples of this include summarization of long pieces of text and question/answering over specific data sources.\\nQuestion Answering: Answering questions over specific documents, only utilizing the information in those documents to construct an answer. A type of Data Augmented Generation.\\nSummarization: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.\\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.\\nEvaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.\\nGenerate similar examples: Generating similar examples to a given input. This is a common use case for many applications, and LangChain provides some prompts/chains for assisting in this.\\nCompare models: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.\\n\\n\\n\\n\\n\\nReference Docs#\\nAll of LangChain’s reference documentation, in one place.

The SitemapLoader constructor accepts a custom scraping function. This feature can be helpful to tailor the scraping process to your specific needs; for example, you might want to avoid scraping headers or navigation elements. The following example shows how to develop and use a custom function to avoid navigation and header elements.Import the beautifulsoup4 library and define the custom function.pip install beautifulsoup4from bs4 import BeautifulSoupdef remove_nav_and_header_elements(content: BeautifulSoup) -> str:    # Find all \'nav\' and \'header\' elements in the BeautifulSoup object    nav_elements = content.find_all(""nav"")    header_elements = content.find_all(""header"")    # Remove each \'nav\' and \'header\' element from the BeautifulSoup object    for element in nav_elements + header_elements:        element.decompose()    return str(content.get_text())Add your custom function to the SitemapLoader object.loader = SitemapLoader(    ""https://langchain.readthedocs.io/sitemap.xml"",    filter_urls=[""https://python.langchain.com/en/latest/""],    parsing_function=remove_nav_and_header_elements,)Local Sitemap\u200bThe sitemap loader can also be used to load local files.sitemap_loader = SitemapLoader(web_path=""example_data/sitemap.xml"", is_local=True)docs = sitemap_loader.load()    Fetching pages: 100%|####################################################################################################################################| 3/3 [00:00<00:00,  3.91it/s]PreviousRSTNextSlackFiltering sitemap URLsAdd custom scraping rulesLocal SitemapCommunityDiscordTwitterGitHubPythonJS/TSMoreHomepageBlogCopyright © 2023 LangChain, Inc.\n\n\n\n', metadata={'source': 'https://python.langchain.com/docs/integrations/document_loaders/sitemap', 'loc': 'https://python.langchain.com/docs/integrations/document_loaders/sitemap', 'changefreq': 'weekly', 'priority': '0.5'})  ##Add custom scraping rules[​](#add-custom-scraping-rules) By default, the parser removes all but the main content of the docusaurus page, which is normally the <article> tag. You also have the option to define an inclusive list HTML tags by providing them as a list utilizing the custom_html_tags parameter. For example:  loader = DocusaurusLoader(     ""https://python.langchain.com"",     filter_urls=[         ""https://python.langchain.com/docs/integrations/document_loaders/sitemap""     ],     # This will only include the content that matches these tags, otherwise they will be removed     custom_html_tags=[""#content"", "".main""], )  You can also define an entirely custom parsing function if you need finer-grained control over the returned content for each page.  The following example shows how to develop and use a custom function to avoid navigation and header elements.  from bs4 import BeautifulSoup   def remove_nav_and_header_elements(content: BeautifulSoup) -> str:     # Find all 'nav' and 'header' elements in the BeautifulSoup object     nav_elements = content.find_all(""nav"")     header_elements = content.find_all(""header"")      # Remove each 'nav' and 'header' element from the BeautifulSoup object     for element in nav_elements + header_elements:         element.decompose()      return str(content.get_text())  Add your custom function to the DocusaurusLoader object.  loader = DocusaurusLoader(     ""https://python.langchain.com"",     filter_urls=[         ""https://python.langchain.com/docs/integrations/document_loaders/sitemap""     ],     parsing_function=remove_nav_and_header_elements, )    "

In other words, he announced that he could prove Fermat’s Last Theorem.

SILVERBERG\n\nhistory of Fermat’s Last Theorem (last because it is the last of Fermat’s questions to be answered) see [5], [6], and [26].\n\nWhat Andrew Wiles announced in Cambridge was that he could prove “many” elliptic curves are modular, sufficiently many to imply Fermat’s Last Theorem. In this paper we will explain Wiles’ work on elliptic curves and its connection with 1 we introduce elliptic curves and modularity, and Fermat’s Last Theorem. give the connection between Fermat’s Last Theorem and the Taniyama-Shimura Conjecture on the modularity of elliptic curves. In 2 we describe how Wiles re- duces the proof of the Taniyama-Shimura Conjecture to what we call the Modular Lifting Conjecture (which can be viewed as a weak form of the Taniyama-Shimura Conjecture), by using a theorem of Langlands and Tunnell. In 4 we show § how the Semistable Modular Lifting Conjecture is related to a conjecture of Mazur on deformations of Galois representations (Conjecture 4.2), and in 5 we describe Wiles’ method of attack on this conjecture. In order to make this survey as acces- sible as possible to nonspecialists, the more technical details are postponed as long as possible, some of them to the appendices.\n\nIn\n\n§\n\n§\n\n3 and §\n\n§\n\nMuch of this report is based on Wiles’ lectures in Cambridge. The authors apol- ogize for any errors we may have introduced. We also apologize to those whose mathematical contributions we, due to our incomplete understanding, do not prop- erly acknowledge.\n\nThe ideas Wiles introduced in his Cambridge lectures will have an important influence on research in number theory. Because of the great interest in this subject and the lack of a publicly available manuscript, we hope this report will be useful to the mathematics community. In early December 1993, shortly before this paper went to press, Wiles announced that “the final calculation of a precise upper bound for the Selmer group in the semistable case” (see 5.4 below) “is not yet § complete as it stands,” but that he believes he will be able to finish it in the near future using the ideas explained in his Cambridge lectures. While Wiles’ proof of Theorem 5.3 below and Fermat’s Last Theorem depends on the calculation he referred to in his December announcement, Theorem 5.4 and Corollary 5.5 do not. Wiles’ work provides for the first time infinitely many modular elliptic curves over the rational numbers which are not isomorphic over the complex numbers (see 5.5 for an explicit infinite family).\n\n5.3 and\n\n§\n\n§\n\nNotation. The integers, rational numbers, complex numbers, and p-adic integers will be denoted Z, Q, C, and Zp, respectively. If F is a field, then ¯F denotes an algebraic closure of F .\n\n1. Connection between Fermat’s Last Theorem and elliptic curves\n\n1.1. Fermat’s Last Theorem follows from modularity of elliptic curves. Suppose Fermat’s Last Theorem were false. Then there would exist nonzero integers a, b, c, and n > 2 such that an + bn = cn. It is easy to see that no generality is lost by assuming that n is a prime greater than three (or greater than four million, by [2]; see [14] for n = 3 and 4) and that a and b are relatively prime. Write down the cubic curve:\n\ny2 = x(x + an)(x\n\nbn).\n\n(1)\n\n−\n\nA REPORT ON WILES’ CAMBRIDGE LECTURES\n\n3\n\n1.4 we will explain what it means for an elliptic curve to be modular. Kenneth Ribet [27] proved that if n is a prime greater than three, a, b, and c are nonzero integers, and an + bn = cn, then the elliptic curve (1) is not modular. But the results announced by Wiles imply the following.\n\nIn\n\n1.3 we will see that such curves are elliptic curves, and in\n\n§\n\n§\n\nTheorem 1.1 (Wiles). If A and B are distinct, nonzero, relatively prime integers, and AB(A\n\nB) is divisible by 16, then the elliptic curve\n\n−\n\ny2 = x(x + A)(x + B)\n\nis modular.\n\nbn with a, b, c, and n coming from our hypothetical solution to a Fermat equation as above, we see that the conditions of Theorem 1.1 are satisfied since n 5 and one of a, b, and c is even. Thus Theorem 1.1 and Ribet’s result together imply Fermat’s Last Theorem!\n\nTaking A = an and B =\n\n−\n\n≥\n\n1.2. History. The story of the connection between Fermat’s Las"

Every elliptic curve over Q is modular.\n\nThe conjecture in the present form was made by Goro Shimura around 1962–64 and has become better understood due to work of Shimura [33–37] and of Andr´e Weil [42] (see also [7]). The Taniyama-Shimura Conjecture is one of the major conjectures in number theory.\n\nBeginning in the late 1960s [15–18], Yves Hellegouarch connected Fermat equa- tions an + bn = cn with elliptic curves of the form (1) and used results about Fer- mat’s Last Theorem to prove results about elliptic curves. The landscape changed abruptly in 1985 when Gerhard Frey stated in a lecture at Oberwolfach that elliptic curves arising from counterexamples to Fermat’s Last Theorem could not be mod- ular [11]. Shortly thereafter Ribet [27] proved this, following ideas of Jean-Pierre Serre [32] (see [24] for a survey). In other words, “Taniyama-Shimura Conjecture\n\nFermat’s Last Theorem”. Thus, the stage was set. A proof of the Taniyama-Shimura Conjecture (or enough of it to know that elliptic curves coming from Fermat equations are modular) would be a proof of Fermat’s Last Theorem.\n\n⇒\n\n1.3. Elliptic curves.\n\nDefinition. An elliptic curve over Q is a nonsingular curve defined by an equation of the form\n\ny2 + a1xy + a3y = x3 + a2x2 + a4x + a6\n\n(2)\n\nwhere the coefficients ai are integers. The solution ( on the elliptic curve.\n\n, ∞\n\n) will be viewed as a point\n\n∞\n\n4\n\nK. RUBIN AND A. SILVERBERG\n\nRemarks. (i) A singular point on a curve f (x, y) = 0 is a point where both partial derivatives vanish. A curve is nonsingular if it has no singular points.\n\n(ii) Two elliptic curves over Q are isomorphic if one can be obtained from the other by changing coordinates x = A2x′ + B, y = A3y′ + Cx′ + D, with A, B, C, D\n\nQ and dividing through by A6.\n\n∈ (iii) Every elliptic curve over Q is isomorphic to one of the form\n\ny2 = x3 + a2x2 + a4x + a6\n\nwith integers ai. A curve of this form is nonsingular if and only if the cubic on the right side has no repeated roots.\n\nExample. The equation y2 = x(x + 32)(x\n\n42) defines an elliptic curve over Q.\n\n−\n\n1.4. Modularity. Let H denote the complex upper half plane C : Im(z) > 0 } where Im(z) is the imaginary part of z. If N is a positive integer, define a group of matrices\n\nz\n\n{\n\n∈\n\na b c d\n\nSL2(Z) : c is divisible by N\n\n.\n\nΓ0(N ) =\n\n∈\n\n(z) = az+b The group Γ0(N ) acts on H by linear fractional transformations cz+d . (cid:9) (cid:1) The quotient space H/Γ0(N ) is a (noncompact) Riemann surface. It can be com- pleted to a compact Riemann surface, denoted X0(N ), by adjoining a finite set of points called cusps. The cusps are the finitely many equivalence classes of Q ∞} under the action of Γ0(N ) (see Chapter 1 of [35]). The complex points of an elliptic curve can also be viewed as a compact Riemann surface.\n\na b c d\n\n(cid:8)(cid:0)\n\n(cid:1)\n\n(cid:0)\n\ni\n\n∪{\n\nDefinition. An elliptic curve E is modular if, for some integer N , there is a holo- morphic map from X0(N ) onto E.\n\nExample. It can be shown that there is a (holomorphic) isomorphism from X0(15) onto the elliptic curve y2 = x(x + 32)(x\n\n42).\n\n−\n\nRemark . There are many equivalent definitions of modularity (see II.4.D of [24] and appendix of [22]). In some cases the equivalence is a deep result. For Wiles’ 1.7 proof of Fermat’s Last Theorem it suffices to use only the definition given in below.\n\n§\n\n§\n\n1.5. Semistability.\n\nDefinition. An elliptic curve over Q is semistable at the prime q if it is isomorphic to an elliptic curve over Q which modulo q either is nonsingular or has a singu- lar point with two distinct tangent directions. An elliptic curve over Q is called semistable if it is semistable at every prime.\n\nExample. The elliptic curve y2 = x(x + 32)(x isomorphic to y2 + xy + y = x3 + x2 x(x + 42)(x\n\n42) is semistable because it is − 10, but the elliptic curve y2 =\n\n10x\n\n−\n\n−\n\n32) is not semistable (it is not semistable at 2).\n\n−\n\n2 we explain how Wiles shows that his main result on Galois representations (Theorem 5.3) implies the following part of the Taniyama-Shimura Conjecture.\n\nBeginning in\n\n§\n\nSemistable Taniyama-Shimura Conjecture. Every semistable elliptic curve over Q is modular.\n\nA REPORT ON WILES’ CAMBRIDGE LECTURES\n\n5\n\nProposition 1.2. The Semistable Taniyama-Shimura Conjecture implies Theorem 1.1.\n\nProof. If A and B are distinct, nonzero, relatively prime integers, write EA,B for the elliptic curve defined by y2 = x(x + A)(x + B). Since EA,B and E−A,−B are isomorphic over the complex numbers (i.e., as Riemann surfaces), EA,B is modular if and only if E−A,−B is modular. If further AB(A B) is divisible by 16, then either EA,B or E−A,−B is semistable (this is easy to check directly; see for example I.1 of [24]). The Semistable Taniyama-Shimura Conjecture now implies that both § EA,B and E−A,−B are modular, and thus implies Theorem 1.1.\n\n−\n\nRemark . In 1.1 we saw that Theorem 1.1 and Ribet’s Theorem together imply Fermat’s Last Theorem. Therefore, the Semistable Taniyama-Shimura Conjecture implies Fermat’s Last Theorem.\n\n§\n\n1.6. Modular forms. In this paper we will work with a definition of modularity which uses modular forms.\n\nDefinition.

In this section we will discuss the Shimura Conjecture other implications in the flow chart.

Semistable Modular Lifting. Let ¯Q denote the algebraic closure of Q in C, and let GQ be the Galois group Gal( ¯Q/Q). If p is a prime, write\n\nF× p\n\n¯εp : GQ\n\n→\n\nfor the character giving the action of GQ on the p-th roots of unity. For the facts about elliptic curves stated below, see [39].

The elliptic curves over Q for which both ¯ρE,3 and ¯ρE,5 are reducible are all known to be modular (see Appendix B.1). Thus we can suppose ¯ρE,5 is irreducible. It suffices to produce an eigenform as in (b) of the Semistable Modular Lifting Conjecture, but this time there is no analogue of the Langlands-Tunnell Theorem to help. Wiles uses the Hilbert Irreducibility Theorem, applied to a parameter space of elliptic curves, to produce another semistable elliptic curve E′ over Q satisfying\n\n(i) ¯ρE′,5 is isomorphic to ¯ρE,5, and (ii) ¯ρE′,3 is irreducible.\n\n(In fact there will be infinitely many such E′; see Appendix B.2.)

The first step (Theorem 5.2), and the key to Wiles’ proof, is to reduce Conjecture 4.2 to a bound on the order of the cotangent space at a prime of R. In 5.2 we § see that the corresponding tangent space is a Selmer group, and in 5.3 we outline a general procedure due to Kolyvagin for bounding sizes of Selmer groups. The input for Kolyvagin’s method is known as an Euler system. The most difficult 5.4), and the part described as “not yet complete” in his part of Wiles’ work ( § December announcement, is his construction of a suitable Euler system. In 5.5 we state the results announced by Wiles (Theorems 5.3 and 5.4 and Corollary 5.5) and explain why Theorem 5.3 suffices for proving the Semistable Taniyama-Shimura Conjecture.

Wiles’ results. Wiles announced two main results (Theorems 5.3 and 5.4 below) in the direction of Mazur’s conjecture, under two different sets of hypotheses on the representation ¯ρ. Theorem 5.3 implies the Semistable Taniyama-Shimura Conjecture and Fermat’s Last Theorem. Wiles’ proof of Theorem 5.3 depends on the not-yet-complete construction of an appropriate Euler system (as in 5.4), while his proof of Theorem 5.4 (though not yet fully checked) does not. For Theorem 5.4, Wiles bounds the Selmer group of 5.2 without constructing a new Euler system, by using results from the Iwasawa theory of imaginary quadratic fields. (These results in turn rely on Kolyvagin’s method and the Euler system of elliptic units; see [31].)\n\n§\n\n§\n\nSince for ease of exposition we defined modularity of representations in terms of Γ0(N ) instead of Γ1(N ), the theorems stated below are weaker than those an- nounced by Wiles, but have the same applications to elliptic curves.

Google Drive | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/google_drive,langchain_docs,"Main:  On this page #Google Drive [Google Drive](https://en.wikipedia.org/wiki/Google_Drive) is a file storage and synchronization service developed by Google.  This notebook covers how to load documents from Google Drive. Currently, only Google Docs are supported.  ##Prerequisites[​](#prerequisites) - Create a Google Cloud project or use an existing project - Enable the [Google Drive API](https://console.cloud.google.com/flows/enableapi?apiid=drive.googleapis.com) - [Authorize credentials for desktop app](https://developers.google.com/drive/api/quickstart/python#authorize_credentials_for_a_desktop_application) - pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib ##🧑 Instructions for ingesting your Google Docs data[​](#-instructions-for-ingesting-your-google-docs-data) By default, the GoogleDriveLoader expects the credentials.json file to be ~/.credentials/credentials.json, but this is configurable using the credentials_path keyword argument. Same thing with token.json - token_path. Note that token.json will be created automatically the first time you use the loader.  The first time you use GoogleDriveLoader, you will be displayed with the consent screen in your browser. If this doesn't happen and you get a RefreshError, do not use credentials_path in your GoogleDriveLoader constructor call. Instead, put that path in a GOOGLE_APPLICATION_CREDENTIALS environmental variable.  GoogleDriveLoader can load from a list of Google Docs document ids or a folder id. You can obtain your folder and document id from the URL:  - Folder: [https://drive.google.com/drive/u/0/folders/1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5](https://drive.google.com/drive/u/0/folders/1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5) -> folder id is ""1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5"" - Document: [https://docs.google.com/document/d/1bfaMQ18_i56204VaQDVeAFpqEijJTgvurupdEDiaUQw/edit](https://docs.google.com/document/d/1bfaMQ18_i56204VaQDVeAFpqEijJTgvurupdEDiaUQw/edit) -> document id is ""1bfaMQ18_i56204VaQDVeAFpqEijJTgvurupdEDiaUQw"" pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib  from langchain.document_loaders import GoogleDriveLoader  loader = GoogleDriveLoader(     folder_id=""1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5"",     token_path=""/path/where/you/want/token/to/be/created/google_token.json"",     # Optional: configure whether to recursively fetch files from subfolders. Defaults to False.     recursive=False, )  docs = loader.load()  When you pass a folder_id by default all files of type document, sheet and pdf are loaded. You can modify this behaviour by passing a file_types argument  loader = GoogleDriveLoader(     folder_id=""1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5"",     file_types=[""document"", ""sheet""],     recursive=False, )  ##Passing in Optional File Loaders[​](#passing-in-optional-file-loaders) When processing files other than Google Docs and Google Sheets, it can be helpful to pass an optional file loader to GoogleDriveLoader. If you pass in a file loader, that file loader will be used on documents that do not have a Google Docs or Google Sheets MIME type. Here is an example of how to load an Excel document from Google Drive using a file loader.  from langchain.document_loaders import GoogleDriveLoader, UnstructuredFileIOLoader  file_id = ""1x9WBtFPWMEAdjcJzPScRsjpjQvpSo_kz"" loader = GoogleDriveLoader(     file_ids=[file_id],     file_loader_cls=UnstructuredFileIOLoader,     file_loader_kwargs={""mode"": ""elements""}, )  docs = loader.load()  docs[0]  You can also process a folder with a mix of files and Google Docs/Sheets using the following pattern:  folder_id = ""1asMOHY1BqBS84JcRbOag5LOJac74gpmD"" loader = GoogleDriveLoader(     folder_id=folder_id,     file_loader_cls=UnstructuredFileIOLoader,     file_loader_kwargs={""mode"": ""elements""}, )  docs = loader.load()  docs[0]  ##Extended usage[​](#extended-usage) An external component can manage the complexity of Google Drive : langchain-googledrive It's compatible with the ̀langchain.document_loaders.GoogleDriveLoader and can be used in its place.  To be compatible with containers, the authentication uses an environment variable ̀GOOGLE_ACCOUNT_FILE` to credential file (for user or service).  pip install langchain-googledrive  folder_id = ""root"" # folder_id='1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5'  # Use the advanced version. from langchain_googledrive.document_loaders import GoogleDriveLoader  loader = GoogleDriveLoader(     folder_id=folder_id,     recursive=False,     num_results=2,  # Maximum number of file to load )  By default, all files with these mime-type can be converted to Document.  - text/text - text/plain - text/html - text/csv - text/markdown - image/png - image/jpeg - application/epub+zip - application/pdf - application/rtf - application/vnd.google-apps.document (GDoc) - application/vnd.google-apps.presentation (GSlide) - application/vnd.google-apps.spreadsheet (GSheet) - application/vnd.google.colaboratory (Notebook colab) - application/vnd.openxmlformats-officedocument.presentationml.presentation (PPTX) - application/vnd.openxmlformats-officedocument.wordprocessingml.document (DOCX) It's possible to update or customize this. See the documentation of GDriveLoader.  But, the corresponding packages must be installed.  pip install unstructured  for doc in loader.load():     print(""---"")     print(doc.page_content.strip()[:60] + ""..."")  ###Customize the search pattern[​](#customize-the-search-pattern) All parameter compatible with Google [list()](https://developers.google.com/drive/api/v3/reference/files/list) API can be set.  To specify the new pattern of the Google request, you can use a PromptTemplate(). The variables for the prompt can be set with kwargs in the constructor. Some pre-formated request are proposed (use {query}, {folder_id} and/or {mime_type}):  You can customize the criteria to select the files. A set of predefined filter are proposed: | template | description | | -------------------------------------"

The conversion can manage in Markdown format:  - bullet - link - table - titles The parameter gslide_mode accepts different values:  - ""single"" : one document with <PAGE BREAK> - ""slide"" : one document by slide - ""elements"" : one document for each elements. loader = GoogleDriveLoader(     template=""gdrive-mime-type"",     mime_type=""application/vnd.google-apps.presentation"",  # Only GSlide files     gslide_mode=""slide"",     num_results=2,  # Maximum number of file to load ) for doc in loader.load():     print(""---"")     print(doc.page_content.strip()[:60] + ""..."")

This field can be used to memorize a summary of the document or others indexed tags (See method lazy_update_description_with_summary()).  If you use the mode=""snippet"", only the description will be used for the body. Else, the metadata['summary'] has the field.  Sometime, a specific filter can be used to extract some information from the filename, to select some files with specific criteria. You can use a filter.  Sometimes, many documents are returned. It's not necessary to have all documents in memory at the same time. You can use the lazy versions of methods, to get one document at a time. It's better to use a complex query in place of a recursive search. For each folder, a query must be applied if you activate recursive=True.  import os  loader = GoogleDriveLoader(     gdrive_api_file=os.environ[""GOOGLE_ACCOUNT_FILE""],     num_results=2,     template=""gdrive-query"",     filter=lambda search, file: ""#test"" not in file.get(""description"", """"),     query=""machine learning"",     supportsAllDrives=False, ) for doc in loader.load():     print(""---"")     print(doc.page_content.strip()[:60] + ""..."")

To use it, you should have the google-cloud-speech python package installed, and a Google Cloud project with the [Speech-to-Text API enabled](https://cloud.google.com/speech-to-text/v2/docs/transcribe-client-libraries#before_you_begin).  - [Bringing the power of large models to Google Cloud’s Speech API](https://cloud.google.com/blog/products/ai-machine-learning/bringing-power-large-models-google-clouds-speech-api) ##Installation & setup[​](#installation--setup) First, you need to install the google-cloud-speech python package.  You can find more info about it on the [Speech-to-Text client libraries](https://cloud.google.com/speech-to-text/v2/docs/libraries) page.  Follow the [quickstart guide](https://cloud.google.com/speech-to-text/v2/docs/sync-recognize) in the Google Cloud documentation to create a project and enable the API.  %pip install google-cloud-speech  ##Example[​](#example) The GoogleSpeechToTextLoader must include the project_id and file_path arguments. Audio files can be specified as a Google Cloud Storage URI (gs://...) or a local file path.  Only synchronous requests are supported by the loader, which has a [limit of 60 seconds or 10MB](https://cloud.google.com/speech-to-text/v2/docs/sync-recognize#:~:text=60%20seconds%20and/or%2010%20MB) per audio file.  from langchain.document_loaders import GoogleSpeechToTextLoader  project_id = ""<PROJECT_ID>"" file_path = ""gs://cloud-samples-data/speech/audio.flac"" # or a local file path: file_path = ""./audio.wav""  loader = GoogleSpeechToTextLoader(project_id=project_id, file_path=file_path)  docs = loader.load()  Note: Calling loader.load() blocks until the transcription is finished.

Grobid | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/grobid,langchain_docs,"Main:  #Grobid GROBID is a machine learning library for extracting, parsing, and re-structuring raw documents.  It is designed and expected to be used to parse academic papers, where it works particularly well. Note: if the articles supplied to Grobid are large documents (e.g. dissertations) exceeding a certain number of elements, they might not be processed.  This loader uses Grobid to parse PDFs into Documents that retain metadata associated with the section of text.

In particular she wants to focus her attentions to making some sort of documentary on what the average Swede thought about certain political issues such as the Vietnam War and race issues in the United States. In between asking politicians and ordinary denizens of Stockholm about their opinions on politics, she has sex with her drama teacher, classmates, and married men.<br /><br />What kills me about I AM CURIOUS-YELLOW is that 40 years ago, this was considered pornographic. Really, the sex and nudity scenes are few and far between, even then it\'s not shot like some cheaply made porno. While my countrymen mind find it shocking, in reality sex and nudity are a major staple in Swedish cinema. Even Ingmar Bergman, arguably their answer to good old boy John Ford, had sex scenes in his films.<br /><br />I do commend the filmmakers for the fact that any sex shown in the film is shown for artistic purposes rather than just to shock people and make money to be shown in pornographic theaters in America.

I\'ve seen R-rated films with male nudity. Granted, they only offer some fleeting views, but where are the R-rated films with gaping vulvas and flapping labia? Nowhere, because they don\'t exist. The same goes for those crappy cable shows: schlongs swinging in the breeze but not a clitoris in sight. And those pretentious indie movies like The Brown Bunny, in which we\'re treated to the site of Vincent Gallo\'s throbbing johnson, but not a trace of pink visible on Chloe Sevigny. Before crying (or implying) ""double-standard"" in matters of nudity, the mentally obtuse should take into account one unavoidably obvious anatomical difference between men and women: there are no genitals on display when actresses appears nude, and the same cannot be said for a man.

I cannot believe out of all the actresses in the world who could play a much better Lucy, the producers decided to get Rachel York. She might be a good actress in other roles but to play the role of Lucille Ball is tough. It is pretty hard to find someone who could resemble Lucille Ball, but they could at least find someone a bit similar in looks and talent.

Ben Gazzara sports his usual cat\'s-got-canary grin in a futile attempt to elevate the meager plot, which requires him to pursue Audrey Hepburn with all the interest of a narcoleptic at an insomnia clinic.

So, I decided that I could not waste more time and immediately see it. Indeed, I have just finished watching ""They All Laughed"" and I found it a very boring overrated movie.

The plot is supposed to be funny (private eyes who fall in love for the women they are chasing), but I have not laughed along the whole story. The coincidences, in a huge city like New York, are ridiculous. Ben Gazarra as an attractive and very seductive man, with the women falling for him as if her were a Brad Pitt, Antonio Banderas or George Clooney, is quite ridiculous.

If you bought it from Apple or from an official retailer like Carphone warehouse etc. Then you\'ll have a year warranty and can get it replaced free.\nIf you bought it second hand, from a third part repair shop or online, then it may still have warranty, unless it is refurbished and has been repaired elsewhere.\nIf this is the case, it may be the screen that needs replacing to solve your issue.\nEither way, wherever you got it, it\'s best to return it and get a refund or a replacement device. :-)\n\n\n\n### Most Helpful Answer\nI had the same issues, screen freezing, opening apps by itself, selecting the screens and typing on it\'s own. I first suspected aliens and then ghosts and then hackers.\niPhone 6 is weak physically and tend to bend on pressure. And my phone had no case or cover.\nI took the phone to apple stores and they said sensors need to be replaced and possibly screen replacement as well. My phone is just 17 months old.\nHere is what I did two days ago and since then it is working like a charm..\nHold the phone in portrait (as if watching a movie). Twist it very very gently. do it few times.Rest the phone for 10 mins (put it on a flat surface). You can now notice those self typing things gone and screen getting stabilized.\nThen, reset the hardware (hold the power and home button till the screen goes off and comes back with apple logo). release the buttons when you see this.\nThen, connect to your laptop and log in to iTunes and reset your phone completely. (please take a back-up first).\nAnd your phone should be good to use again.\nWhat really happened here for me is that the sensors might have stuck to the screen and with mild twisting, they got disengaged/released.\nI posted this in Apple Community and the moderators deleted it, for the best reasons known to them.\nInstead of throwing away your phone (or selling cheaply), try this and you could be saving your phone.\nLet me know how it goes.\n\n\n\n### Other Answer\nIt was the charging cord! I bought a gas station braided cord and it was the culprit. Once I plugged my OEM cord into the phone the GHOSTS went away.\n\n\n\n### Other Answer\nI\'ve same issue that I just get resolved.  I first tried to restore it from iCloud back, however it was not a software issue or any virus issue, so after restore same problem continues. Then I get my phone to local area iphone repairing lab, and they detected that it is an LCD issue. LCD get out of order without any reason (It was neither hit or nor slipped, but LCD get out of order all and sudden, while using it) it started opening things at random. I get LCD replaced with new one, that cost me $80.00 in total  ($70.00 LCD charges + $10.00 as labor charges to fix it). iPhone is back to perfect mode now.  It was iphone 6s. Thanks.\n\n\n\n### Other Answer\nI was having the same issue with my 6 plus, I took it to a repair shop, they opened the phone, disconnected the three ribbons the screen has, blew up and cleaned the connectors and connected the screen again and it solved the issue… it’s hardware, not software.\n\n\n\n### Other Answer\nHey.\nJust had this problem now. As it turns out, you just need to plug in your phone. I use a case and when I took it off I noticed that there was a lot of dust and dirt around the areas that the case didn\'t cover. I shined a light in my ports and noticed they were filled with dust. Tomorrow I plan on using pressurized air to clean it out and the problem should be solved.  If you plug in your phone and unplug it and it stops the issue, I recommend cleaning your phone thoroughly.\n\n\n\n### Other Answer\nI simply changed the power supply and problem was gone.

The cord was fine but not the block.\n\n\n\n### Other Answer\nSomeone ask!  I purchased my iPhone 6s Plus for 1000 from at&t.  Before I touched it, I purchased a otter defender case.  I read where at&t said touch desease was due to dropping!  Bullshit!!  I am 56 I have never dropped it!! Looks brand new!  Never dropped or abused any way!  I have my original charger.  I am going to clean it and try everyone’s advice.  It really sucks!  I had 40,000,000 on my heart of Vegas slots!  I play every day.  I would be spinning and my fingers were no where max buttons and it would light up and switch to max.  It did it 3 times before I caught it light up by its self.  It sucks. Hope I can fix it!!!!\n\n\n\n### Other Answer\nNo answer, but same problem with iPhone 6 plus--random, self-generated jumping amongst apps and typing on its own--plus freezing regularly (aha--maybe that\'s what the ""plus"" in ""6 plus"" refers to?).  An Apple Genius recommended upgrading to iOS 11.3.1 from 11.2.2, to see if that fixed the trouble.  If it didn\'t, Apple will sell me a new phone for $168!  Of couese the OS upgrade didn\'t fix the problem.  Thanks for helping me figure out that it\'s most likely a hardware problem--which the ""genius"" probably knows too.\nI\'m getting ready to go Android.\n\n\n\n### Other Answer\nI experienced similar ghost touches.  Two weeks ago, I changed my iPhone 6 Plus shell (I had forced the phone into it because it’s pretty tight), and also put a new glass screen protector (the edges of the protector don’t stick to the screen, weird, so I brushed pressure on the edges at times to see if they may smooth out one day miraculously).  I’m not sure if I accidentally bend the phone when I installed the shell,  or, if I got a defective glass protector that messes up the touch sensor. Well, yesterday was the worse day, keeps dropping calls and ghost pressing keys for me when I was on a call.  I got fed up, so I removed the screen protector, and so far problems have not reoccurred yet. I’m crossing my fingers that problems indeed solved.\n\n\n\n### Other Answer\nthank you so much for this post! i was struggling doing the reset because i cannot type userids and passwords correctly because the iphone 6 plus i have kept on typing letters incorrectly. I have been doing it for a day until i come across this article. Very helpful! God bless you!!\n\n\n\n### Other Answer\nI just turned it off, and turned it back on.\n\n\n\n### Other Answer\nMy problem has not gone away completely but its better now i changed my charger and turned off prediction ....,,,now it rarely happens\n\n\n\n### Other Answer\nI tried all of the above. I then turned off my home cleaned it with isopropyl alcohol 90%. Then I baked it in my oven on warm for an hour and a half over foil. Took it out and set it cool completely on the glass top stove. Then I turned on and it worked.\n\n\n\n### Other Answer\nI think at& t should man up and fix your phone for free!  You pay a lot for a Apple they should back it.  I did the next 30 month payments and finally have it paid off in June.  My iPad sept.  Looking forward to a almost 100 drop in my phone bill!  Now this crap!!! Really\n\n\n\n### Other Answer\nIf your phone is JailBroken, suggest downloading a virus.  While all my symptoms were similar, there was indeed a virus/malware on the phone which allowed for remote control of my iphone (even while in lock mode).  My mistake for buying a third party iphone i suppose.  Anyway i have since had the phone restored to factory and everything is working as expected for now.  I will of course keep you posted if this changes.  Thanks to all for the helpful posts, really helped me narrow a few things down.\n\n\n\n### Other Answer\nWhen my phone was doing this, it ended up being the screen protector that i got from 5 below. I took it off and it stopped. I ordered more protectors from amazon and replaced it\n\n\n\n### Other Answer\niPhone 6 Plus first generation….I had the same issues as all above, apps opening by themselves, self typing, ultra sensitive screen, items jumping around all over….it even called someone on FaceTime twice by itself when I was not in the room…..I thought the phone was toast and i’d have to buy a new one took me a while to figure out but it was the extra cheap block plug I bought at a dollar store for convenience of an extra charging station when I move around the house from den to living room…..cord was fine but bought a new Apple brand block plug…no more problems works just fine now. This issue was a recent event so had to narrow things down to what had changed recently to my phone so I could figure it out.\nI even had the same problem on a laptop with documents opening up by themselves…..a laptop that was plugged in to the same wall plug as my phone charger with the dollar store block plug….until I changed the block plug.\n\n\n\n### Other Answer\nHad the problem: Inherited a 6s Plus from my wife. She had no problem with it.\nLooks like it was merely the cheap phone case I purchased on Amazon. It was either pinching the edges or torquing the screen/body of the phone. Problem solved.\n\n\n\n### Other Answer\nI bought my phone on march 6 and it was a brand new, but It sucks me uo because it freezing, shaking and control by itself. I went to the store where I bought this and I told them to replacr it, but they told me I have to pay it because Its about lcd issue. Please help me what other ways to fix it. Or should I try to remove the screen or should I follow your step above.\n\n\n\n### Other Answer\nI tried everything and it seems to come back to needing the original iPhone cable…or at least another 1 that would have come with another iPhone…not the $5 Store fast charging cables.  My original cable is pretty beat up - like most that I see - but I’ve been beaten up much MUCH less by sticking with its use!  I didn’t find that the casing/shell around it or not made any diff.\n\n\n\n### Other Answer\ngreat now I hav"

I got it replaced at local repair shop, so far phone is working fine.\n\n\n\n### Other Answer\nthis problem in iphone 6 has many different scenarios and solutions, first try to reconnect the lcd screen to the motherboard again, if didnt solve, try to replace the lcd connector on the motherboard, if not solved, then remains two issues, lcd screen it self or touch IC. in my country some repair shops just change them all for almost 40$ since they dont want to troubleshoot one by one. readers of this comment also should know that partial screen not responding in other iphone models might also have an issue in LCD connector on the motherboard, specially if you lock/unlock screen and screen works again for sometime. lcd connectors gets disconnected lightly from the motherboard due to multiple falls and hits after sometime. best of luck for all\n\n\n\n### Other Answer\nI am facing the same issue whereby these ghost touches type and open apps , I am using an original Iphone cable , how to I fix this issue.\n\n\n\n### Other Answer\nThere were two issues with the phone I had troubles with. It was my dads and turns out he carried it in his pocket. The phone itself had a little bend in it as a result. A little pressure in the opposite direction helped the issue. But it also had a tiny crack in the screen which wasnt obvious, once we added a screen protector this fixed the issues entirely.\n\n\n\n### Other Answer\nI had the same problem with my 64Gb iPhone 6+.

You may either initialize the loader directly with the access token, or store it in the environment variable JOPLIN_ACCESS_TOKEN.

Follow the instructions at this document to add the following SCOPES (offline_access and Sites.Read.All) to your application. To retrieve files from your Document Library, you will need its ID. To obtain it, you will need values of Tenant Name, Collection ID, and Subsite ID. To find your Tenant Name follow the instructions at this document. Once you got this, just remove .onmicrosoft.com from the value and hold the rest as your Tenant Name. To obtain your Collection ID and Subsite ID, you will need your SharePoint site-name. Your SharePoint site URL has the following format https://<tenant-name>.sharepoint.com/sites/<site-name>. The last part of this URL is the site-name. To Get the Site Collection ID, hit this URL in the browser: https://<tenant>.sharepoint.com/sites/<site-name>/_api/site/id and copy the value of the Edm.Guid property. To get the Subsite ID (or web ID) use: https://<tenant>.sharepoint.com/<site-name>/_api/web/id and copy the value of the Edm.Guid property. The SharePoint site ID has the following format: <tenant-name>.sharepoint.com,<Collection ID>,<subsite ID>. You can hold that value to use in the next step.

It is an all-in-one workspace for notetaking, knowledge and data management, and project and task management.  NotionDBLoader is a Python class for loading content from a Notion database. It retrieves pages from the database, reads their content, and returns a list of Document objects.  ##Requirements[​](#requirements) - A Notion Database - Notion Integration Token ##Setup[​](#setup) ###1. Create a Notion Table Database[​](#1-create-a-notion-table-database) Create a new table database in Notion. You can add any column to the database and they will be treated as metadata. For example you can add the following columns:  - Title: set Title as the default property. - Categories: A Multi-select property to store categories associated with the page. - Keywords: A Multi-select property to store keywords associated with the page. Add your content to the body of each page in the database. The NotionDBLoader will extract the content and metadata from these pages.  ##2. Create a Notion Integration[​](#2-create-a-notion-integration) To create a Notion Integration, follow these steps:  - Visit the [Notion Developers](https://www.notion.com/my-integrations) page and log in with your Notion account. - Click on the ""+ New integration"" button. - Give your integration a name and choose the workspace where your database is located. - Select the require capabilities, this extension only need the Read content capability - Click the ""Submit"" button to create the integration. Once the integration is created, you'll be provided with an Integration Token (API key). Copy this token and keep it safe, as you'll need it to use the NotionDBLoader. ###3. Connect the Integration to the Database[​](#3-connect-the-integration-to-the-database) To connect your integration to the database, follow these steps:  - Open your database in Notion. - Click on the three-dot menu icon in the top right corner of the database view. - Click on the ""+ New integration"" button. - Find your integration, you may need to start typing its name in the search box. - Click on the ""Connect"" button to connect the integration to the database. ###4. Get the Database ID[​](#4-get-the-database-id) To get the database ID, follow these steps:  - Open your database in Notion. - Click on the three-dot menu icon in the top right corner of the database view. - Select ""Copy link"" from the menu to copy the database URL to your clipboard. - The database ID is the long string of alphanumeric characters found in the URL. It typically looks like this: [https://www.notion.so/username/8935f9d140a04f95a872520c4f123456?v=](https://www.notion.so/username/8935f9d140a04f95a872520c4f123456?v=).... In this example, the database ID is 8935f9d140a04f95a872520c4f123456. With the database properly set up and the integration token and database ID in hand, you can now use the NotionDBLoader code to load content and metadata from your Notion database.  ##Usage[​](#usage) NotionDBLoader is part of the langchain package's document loaders. You can use it as follows:  from getpass import getpass  NOTION_TOKEN = getpass() DATABASE_ID = getpass()      ········     ········  from langchain.document_loaders import NotionDBLoader  loader = NotionDBLoader(     integration_token=NOTION_TOKEN,     database_id=DATABASE_ID,     request_timeout_sec=30,  # optional, defaults to 10 )  docs = loader.load()  print(docs)          "
Nuclia | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/nuclia,langchain_docs,"Main:  On this page #Nuclia [Nuclia](https://nuclia.com) automatically indexes your unstructured data from any internal and external source, providing optimized search results and generative answers. It can handle video and audio transcription, image content extraction, and document parsing.  The Nuclia Understanding API supports the processing of unstructured data, including text, web pages, documents, and audio/video contents. It extracts all texts wherever they are (using speech-to-text or OCR when needed), it also extracts metadata, embedded files (like images in a PDF), and web links. If machine learning is enabled, it identifies entities, provides a summary of the content and generates embeddings for all the sentences.  ##Setup[​](#setup) To use the Nuclia Understanding API, you need to have a Nuclia account. You can create one for free at [https://nuclia.cloud](https://nuclia.cloud), and then [create a NUA key](https://docs.nuclia.dev/docs/docs/using/understanding/intro).  #!pip install --upgrade protobuf #!pip install nucliadb-protos  import os  os.environ[""NUCLIA_ZONE""] = ""<YOUR_ZONE>""  # e.g. europe-1 os.environ[""NUCLIA_NUA_KEY""] = ""<YOUR_API_KEY>""  ##Example[​](#example) To use the Nuclia document loader, you need to instantiate a NucliaUnderstandingAPI tool:  from langchain.tools.nuclia import NucliaUnderstandingAPI  nua = NucliaUnderstandingAPI(enable_ml=False)  from langchain.document_loaders.nuclia import NucliaLoader  loader = NucliaLoader(""./interview.mp4"", nua)  You can now call the load the document in a loop until you get the document.  import time  pending = True while pending:     time.sleep(15)     docs = loader.load()     if len(docs) > 0:         print(docs[0].page_content)         print(docs[0].metadata)         pending = False     else:         print(""waiting..."")  ##Retrieved information[​](#retrieved-information) Nuclia returns the following information:  - file metadata - extracted text - nested text (like text in an embedded image) - paragraphs and sentences splitting (defined by the position of their first and last characters, plus start time and end time for a video or audio file) - links - a thumbnail - embedded files Note:  Generated files (thumbnail, extracted embedded files, etc.) are provided as a token. You can download them with the [/processing/download endpoint](https://docs.nuclia.dev/docs/api#operation/Download_binary_file_processing_download_get).  Also at any level, if an attribute exceeds a certain size, it will be put in a downloadable file and will be replaced in the document by a file pointer. This will consist of {""file"": {""uri"": ""JWT_TOKEN""}}. The rule is that if the size of the message is greater than 1000000 characters, the biggest parts will be moved to downloadable files. First, the compression process will target vectors. If that is not enough, it will target large field metadata, and finally it will target extracted text.  "
Obsidian | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/obsidian,langchain_docs,"Main:  #Obsidian [Obsidian](https://obsidian.md/) is a powerful and extensible knowledge base that works on top of your local folder of plain text files.

Obsidian files also sometimes contain [metadata](https://help.obsidian.md/Editing+and+formatting/Metadata) which is a YAML block at the top of the file. These values will be added to the document's metadata. (ObsidianLoader can also be passed a collect_metadata=False argument to disable this behavior.)  from langchain.document_loaders import ObsidianLoader  loader = ObsidianLoader(""<path-to-obsidian>"")  docs = loader.load()    "

Microsoft OneNote | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/onenote,langchain_docs,"Main:  On this page #Microsoft OneNote This notebook covers how to load documents from OneNote.  ##Prerequisites[​](#prerequisites) - Register an application with the [Microsoft identity platform](https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app) instructions. - When registration finishes, the Azure portal displays the app registration's Overview pane. You see the Application (client) ID. Also called the client ID, this value uniquely identifies your application in the Microsoft identity platform. - During the steps you will be following at item 1, you can set the redirect URI as http://localhost:8000/callback - During the steps you will be following at item 1, generate a new password (client_secret) under Application Secrets section. - Follow the instructions at this [document](https://learn.microsoft.com/en-us/azure/active-directory/develop/quickstart-configure-app-expose-web-apis#add-a-scope) to add the following SCOPES (Notes.Read) to your application. - You need to install the msal and bs4 packages using the commands pip install msal and pip install beautifulsoup4. - At the end of the steps you must have the following values: - CLIENT_ID - CLIENT_SECRET ##🧑 Instructions for ingesting your documents from OneNote[​](#-instructions-for-ingesting-your-documents-from-onenote) ###🔑 Authentication[​](#-authentication) By default, the OneNoteLoader expects that the values of CLIENT_ID and CLIENT_SECRET must be stored as environment variables named MS_GRAPH_CLIENT_ID and MS_GRAPH_CLIENT_SECRET respectively. You could pass those environment variables through a .env file at the root of your application or using the following command in your script.  os.environ['MS_GRAPH_CLIENT_ID'] = ""YOUR CLIENT ID"" os.environ['MS_GRAPH_CLIENT_SECRET'] = ""YOUR CLIENT SECRET""  This loader uses an authentication called [on behalf of a user](https://learn.microsoft.com/en-us/graph/auth-v2-user?context=graph%2Fapi%2F1.0&view=graph-rest-1.0). It is a 2 step authentication with user consent. When you instantiate the loader, it will call will print a url that the user must visit to give consent to the app on the required permissions. The user must then visit this url and give consent to the application. Then the user must copy the resulting page url and paste it back on the console. The method will then return True if the login attempt was successful.  from langchain.document_loaders.onenote import OneNoteLoader  loader = OneNoteLoader(notebook_name=""NOTEBOOK NAME"", section_name=""SECTION NAME"", page_title=""PAGE TITLE"")  Once the authentication has been done, the loader will store a token (onenote_graph_token.txt) at ~/.credentials/ folder. This token could be used later to authenticate without the copy/paste steps explained earlier. To use this token for authentication, you need to change the auth_with_token parameter to True in the instantiation of the loader.  from langchain.document_loaders.onenote import OneNoteLoader  loader = OneNoteLoader(notebook_name=""NOTEBOOK NAME"", section_name=""SECTION NAME"", page_title=""PAGE TITLE"", auth_with_token=True)  Alternatively, you can also pass the token directly to the loader. This is useful when you want to authenticate with a token that was generated by another application. For instance, you can use the [Microsoft Graph Explorer](https://developer.microsoft.com/en-us/graph/graph-explorer) to generate a token and then pass it to the loader.  from langchain.document_loaders.onenote import OneNoteLoader  loader = OneNoteLoader(notebook_name=""NOTEBOOK NAME"", section_name=""SECTION NAME"", page_title=""PAGE TITLE"", access_token=""TOKEN"")  ###🗂️ Documents loader[​](#️-documents-loader) ####📑 Loading pages from a OneNote Notebook[​](#-loading-pages-from-a-onenote-notebook) OneNoteLoader can load pages from OneNote notebooks stored in OneDrive. You can specify any combination of notebook_name, section_name, page_title to filter for pages under a specific notebook, under a specific section, or with a specific title respectively. For instance, you want to load all pages that are stored under a section called Recipes within any of your notebooks OneDrive.  from langchain.document_loaders.onenote import OneNoteLoader  loader = OneNoteLoader(section_name=""Recipes"", auth_with_token=True) documents = loader.load()  ####📑 Loading pages from a list of Page IDs[​](#-loading-pages-from-a-list-of-page-ids) Another possibility is to provide a list of object_ids for each page you want to load. For that, you will need to query the [Microsoft Graph API](https://developer.microsoft.com/en-us/graph/graph-explorer) to find all the documents ID that you are interested in. This [link](https://learn.microsoft.com/en-us/graph/onenote-get-content#page-collection) provides a list of endpoints that will be helpful to retrieve the documents ID.  For instance, to retrieve information about all pages that are stored in your notebooks, you need make a request to: https://graph.microsoft.com/v1.0/me/onenote/pages. Once you have the list of IDs that you are interested in, then you can instantiate the loader with the following parameters.  from langchain.document_loaders.onenote import OneNoteLoader  loader = OneNoteLoader(object_ids=[""ID_1"", ""ID_2""], auth_with_token=True) documents = loader.load()    "

Amazon Textract | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/pdf-amazonTextractPDFLoader,langchain_docs,"Main:  On this page #Amazon Textract Amazon Textract is a machine learning (ML) service that automatically extracts text, handwriting, and data from scanned documents. It goes beyond simple optical character recognition (OCR) to identify, understand, and extract data from forms and tables. Today, many companies manually extract data from scanned documents such as PDFs, images, tables, and forms, or through simple OCR software that requires manual configuration (which often must be updated when the form changes). To overcome these manual and expensive processes, Textract uses ML to read and process any type of document, accurately extracting text, handwriting, tables, and other data with no manual effort. You can quickly automate document processing and act on the information extracted, whether you’re automating loans processing or extracting information from invoices and receipts. Textract can extract the data in minutes instead of hours or days.  This sample demonstrates the use of Amazon Textract in combination with LangChain as a DocumentLoader.  Textract supports PDF, TIFF, PNG and JPEG format.  Check [https://docs.aws.amazon.com/textract/latest/dg/limits-document.html](https://docs.aws.amazon.com/textract/latest/dg/limits-document.html) for supported document sizes, languages and characters.  # !pip install langchain boto3 openai tiktoken python-dotenv -q pip install boto3 openai tiktoken python-dotenv -q pip install -e /Users/schadem/code/github/schadem/langchain/libs/langchain      DEPRECATION: amazon-textract-pipeline-pagedimensions 0.0.8 has a non-standard dependency specifier Pillow>=9.4.*. pip 23.3 will enforce this behaviour change.

However, it is unclear how ChatGPT would perform on an examination assessing professionalism and situational judgement for doctors.\nOBJECTIVE: We evaluated the performance of ChatGPT on the Situational Judgement Test (SJT): a national examination taken by all final-year medical students in the United Kingdom. This examination is designed to assess attributes such as communication, teamwork, patient safety, prioritization skills, professionalism, and ethics.\nMETHODS: All questions from the UK Foundation Programme Office's (UKFPO's) 2023 SJT practice examination were inputted into ChatGPT. For each question, ChatGPT's answers and rationales were recorded and assessed on the basis of the official UK Foundation Programme Office scoring template. Questions were categorized into domains of Good Medical Practice on the basis of the domains referenced in the rationales provided in the scoring sheet. Questions without clear domain links were screened by reviewers and assigned one or multiple domains. ChatGPT's overall performance, as well as its performance across the domains of Good Medical Practice, was evaluated.\nRESULTS: Overall, ChatGPT performed well, scoring 76% on the SJT but scoring full marks on only a few questions (9%), which may reflect possible flaws in ChatGPT's situational judgement or inconsistencies in the reasoning across questions (or both) in the examination itself. ChatGPT demonstrated consistent performance across the 4 outlined domains in Good Medical Practice for doctors.\nCONCLUSIONS: Further research is needed to understand the potential applications of large language models, such as ChatGPT, in medical education for standardizing questions and providing consistent rationales for examinations assessing professionalism and ethics.""

Recursive URL | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/recursive_url,langchain_docs,"Main:  #Recursive URL We may want to process load all URLs under a root directory.  For example, let's look at the [Python 3.9 Document](https://docs.python.org/3.9/).  This has many interesting child pages that we may want to read in bulk.  Of course, the WebBaseLoader can load a list of pages.  But, the challenge is traversing the tree of child pages and actually assembling that list!  We do this using the RecursiveUrlLoader.  This also gives us the flexibility to exclude some children, customize the extractor, and more.  #Parameters - url: str, the target url to crawl. - exclude_dirs: Optional[str], webpage directories to exclude. - use_async: Optional[bool], wether to use async requests, using async requests is usually faster in large tasks. However, async will disable the lazy loading feature(the function still works, but it is not lazy). By default, it is set to False. - extractor: Optional[Callable[[str], str]], a function to extract the text of the document from the webpage, by default it returns the page as it is. It is recommended to use tools like goose3 and beautifulsoup to extract the text. By default, it just returns the page as it is. - max_depth: Optional[int] = None, the maximum depth to crawl. By default, it is set to 2. If you need to crawl the whole website, set it to a number that is large enough would simply do the job. - timeout: Optional[int] = None, the timeout for each request, in the unit of seconds. By default, it is set to 10. - prevent_outside: Optional[bool] = None, whether to prevent crawling outside the root url. By default, it is set to True. from langchain.document_loaders.recursive_url_loader import RecursiveUrlLoader  Let's try a simple example.  from bs4 import BeautifulSoup as Soup  url = ""https://docs.python.org/3.9/"" loader = RecursiveUrlLoader(     url=url, max_depth=2, extractor=lambda x: Soup(x, ""html.parser"").text ) docs = loader.load()  docs[0].page_content[:50]      '\n\n\n\n\nPython Frequently Asked Questions — Python 3.'  docs[-1].metadata      {'source': 'https://docs.python.org/3.9/library/index.html',      'title': 'The Python Standard Library — Python 3.9.17 documentation',      'language': None}  However, since it's hard to perform a perfect filter, you may still see some irrelevant results in the results.

Rockset | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_loaders/rockset,langchain_docs,"Main:  On this page #Rockset Rockset is a real-time analytics database which enables queries on massive, semi-structured data without operational burden. With Rockset, ingested data is queryable within one second and analytical queries against that data typically execute in milliseconds. Rockset is compute optimized, making it suitable for serving high concurrency applications in the sub-100TB range (or larger than 100s of TBs with rollups).  This notebook demonstrates how to use Rockset as a document loader in langchain. To get started, make sure you have a Rockset account and an API key available.  ##Setting up the environment[​](#setting-up-the-environment) - Go to the [Rockset console](https://console.rockset.com/apikeys) and get an API key. Find your API region from the [API reference](https://rockset.com/docs/rest-api/#introduction). For the purpose of this notebook, we will assume you're using Rockset from Oregon(us-west-2). - Set your the environment variable ROCKSET_API_KEY. - Install the Rockset python client, which will be used by langchain to interact with the Rockset database. pip install rockset  #Loading Documents The Rockset integration with LangChain allows you to load documents from Rockset collections with SQL queries. In order to do this you must construct a RocksetLoader object. Here is an example snippet that initializes a RocksetLoader.  from langchain.document_loaders import RocksetLoader from rockset import Regions, RocksetClient, models  loader = RocksetLoader(     RocksetClient(Regions.usw2a1, ""<api key>""),     models.QueryRequestSql(query=""SELECT * FROM langchain_demo LIMIT 3""),  # SQL query     [""text""],  # content columns     metadata_keys=[""id"", ""date""],  # metadata columns )  Here, you can see that the following query is run:  SELECT * FROM langchain_demo LIMIT 3  The text column in the collection is used as the page content, and the record's id and date columns are used as metadata (if you do not pass anything into metadata_keys, the whole Rockset document will be used as metadata).  To execute the query and access an iterator over the resulting Documents, run:  loader.lazy_load()  To execute the query and access all resulting Documents at once, run:  loader.load()  Here is an example response of loader.load():  [     Document(         page_content=""Lorem ipsum dolor sit amet, consectetur adipiscing elit.

This is the second sentence.  You can define you own function to join content columns by setting the content_columns_joiner argument in the RocksetLoader constructor. content_columns_joiner is a method that takes in a List[Tuple[str, Any]]] as an argument, representing a list of tuples of (column name, column value). By default, this is a method that joins each column value with a new line.  For example, if you wanted to join sentence1 and sentence2 with a space instead of a new line, you could set content_columns_joiner like so:  RocksetLoader(     RocksetClient(Regions.usw2a1, ""<api key>""),     models.QueryRequestSql(query=""SELECT * FROM langchain_demo LIMIT 1 WHERE id=38""),     [""sentence1"", ""sentence2""],     content_columns_joiner=lambda docs: "" "".join(         [doc[1] for doc in docs]     ),  # join with space instead of /n )  The page_content of the resulting Document would be:  This is the first sentence. This is the second sentence.  Oftentimes you want to include the column name in the page_content. You can do that like this:  RocksetLoader(     RocksetClient(Regions.usw2a1, ""<api key>""),     models.QueryRequestSql(query=""SELECT * FROM langchain_demo LIMIT 1 WHERE id=38""),     [""sentence1"", ""sentence2""],     content_columns_joiner=lambda docs: ""\n"".join(         [f""{doc[0]}: {doc[1]}"" for doc in docs]     ), )  This would result in the following page_content:  sentence1: This is the first sentence. sentence2: This is the second sentence.

It’s been thrilling to see Clojure and Datomic successfully applied at scale.          I look forward to continuing to lead ongoing work maintaining and enhancing Clojure with Alex, Stu, Fogus and many others, as an independent developer once again. We have many useful things planned for 1.12 and beyond. The community remains friendly, mature and productive, and is taking Clojure into many interesting new domains.          I want to highlight and thank Nubank for their ongoing sponsorship of Alex, Fogus and the core team, as well as the Clojure community at large.          Stu will continue to lead the development of Datomic at Nubank, where the Datomic team grows and thrives. I’m particularly excited to see where the new free availability of Datomic will lead.          My time with Cognitect remains the highlight of my career. I have learned from absolutely everyone on our team, and am forever grateful to all for our interactions. There are too many people to thank here, but I must extend my sincerest appreciation and love to Stu and Justin for (repeatedly) taking a risk on me and my ideas, and for being the best of partners and friends, at all times fully embodying the notion of integrity. And of course to Alex Miller - who possesses in abundance many skills I lack, and without whose indomitable spirit, positivity and friendship Clojure would not have become what it did.          I have made many friends through Clojure and Cognitect, and I hope to nurture those friendships moving forward.

Although it\'s a smaller car, the PEAR seats six thanks to front and rear bench seats. Oh, and it has a frunk, which the company is calling the ""froot,"" something that will satisfy some British English speakers like Ars\' friend and motoring journalist Jonny Smith.\n\nBut most exciting is the price—starting at $29,900 and scheduled for 2025. Fisker plans to contract with Foxconn to build the PEAR in Lordstown, Ohio, meaning it would be eligible for federal tax incentives.\n\nAdvertisement\n\nThe Fisker Alaska is the company\'s pickup truck, built on a modified version of the platform used by the Ocean. It has an extendable cargo bed, which can be as little as 4.5 feet (1,371 mm) or as much as 9.2 feet (2,804 mm) long. Fisker claims it will be both the lightest EV pickup on sale and the most sustainable pickup truck in the world. Range will be an estimated 230–240 miles (370–386 km).\n\nThis, too, is slated for 2025, and also at a relatively affordable price, starting at $45,400.

The dataset consists of 7 languages: Arabic, German, Spanish, English, Hindi, Vietnamese, Chinese.  - Homepage: [https://github.com/facebookresearch/MLQA](https://github.com/facebookresearch/MLQA) - Source code: tfds.datasets.mlqa.Builder - Download size: 72.21 MiB # Feature structure of `mlqa/en` dataset:  FeaturesDict(     {         ""answers"": Sequence(             {                 ""answer_start"": int32,                 ""text"": Text(shape=(), dtype=string),             }         ),         ""context"": Text(shape=(), dtype=string),         ""id"": string,         ""question"": Text(shape=(), dtype=string),         ""title"": Text(shape=(), dtype=string),     } )  import tensorflow as tf import tensorflow_datasets as tfds  # try directly access this dataset: ds = tfds.load(""mlqa/en"", split=""test"") ds = ds.take(1)  # Only take a single example ds      <_TakeDataset element_spec={'answers': {'answer_start': TensorSpec(shape=(None,), dtype=tf.int32, name=None), 'text': TensorSpec(shape=(None,), dtype=tf.string, name=None)}, 'context': TensorSpec(shape=(), dtype=tf.string, name=None), 'id': TensorSpec(shape=(), dtype=tf.string, name=None), 'question': TensorSpec(shape=(), dtype=tf.string, name=None), 'title': TensorSpec(shape=(), dtype=tf.string, name=None)}>  Now we have to create a custom function to convert dataset sample into a Document.  This is a requirement. There is no standard format for the TF datasets that's why we need to make a custom transformation function.  Let's use context field as the Document.page_content and place other fields in the Document.metadata.  def decode_to_str(item: tf.Tensor) -> str:     return item.numpy().decode(""utf-8"")   def mlqaen_example_to_document(example: dict) -> Document:     return Document(         page_content=decode_to_str(example[""context""]),         metadata={             ""id"": decode_to_str(example[""id""]),             ""title"": decode_to_str(example[""title""]),             ""question"": decode_to_str(example[""question""]),             ""answer"": decode_to_str(example[""answers""][""text""][0]),         },     )   for example in ds:     doc = mlqaen_example_to_document(example)     print(doc)     break      page_content='After completing the journey around South America, on 23 February 2006, Queen Mary 2 met her namesake, the original RMS Queen Mary, which is permanently docked at Long Beach, California.

We believe that the most powerful and differentiated applications will not only call out to a language model, but will also be:          1. _Data-aware_: connect a language model to other sources of data          2. _Agentic_: allow a language model to interact with its environment               The LangChain framework is designed around these principles.          This is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see [here](https://docs.langchain.com/docs/). For the JavaScript documentation, see [here](https://js.langchain.com/docs/).          ## Getting Started [\#](\#getting-started ""Permalink to this headline"")          How to get started using LangChain to create an Language Model application.          - [Quickstart Guide](https://python.langchain.com/en/latest/getting_started/getting_started.html)               Concepts and terminology.          - [Concepts and terminology](https://python.langchain.com/en/latest/getting_started/concepts.html)               Tutorials created by community experts and presented on YouTube.          - [Tutorials](https://python.langchain.com/en/latest/getting_started/tutorials.html)               ## Modules [\#](\#modules ""Permalink to this headline"")          These modules are the core abstractions which we view as the building blocks of any LLM-powered application.          For each module LangChain provides standard, extendable interfaces. LanghChain also provides external integrations and even end-to-end implementations for off-the-shelf use.          The docs for each module contain quickstart examples, how-to guides, reference docs, and conceptual guides.          The modules are (from least to most complex):          - [Models](https://python.langchain.com/docs/modules/model_io/models/): Supported model types and integrations.          - [Prompts](https://python.langchain.com/en/latest/modules/prompts.html): Prompt management, optimization, and serialization.          - [Memory](https://python.langchain.com/en/latest/modules/memory.html): Memory refers to state that is persisted between calls of a chain/agent.          - [Indexes](https://python.langchain.com/en/latest/modules/data_connection.html): Language models become much more powerful when combined with application-specific data - this module contains interfaces and integrations for loading, querying and updating external data.          - [Chains](https://python.langchain.com/en/latest/modules/chains.html): Chains are structured sequences of calls (to an LLM or to a different utility).          - [Agents](https://python.langchain.com/en/latest/modules/agents.html): An agent is a Chain in which an LLM, given a high-level directive and a set of tools, repeatedly decides an action, executes the action and observes the outcome until the high-level directive is complete.          - [Callbacks](https://python.langchain.com/en/latest/modules/callbacks/getting_started.html): Callbacks let you log and stream the intermediate steps of any chain, making it easy to observe, debug, and evaluate the internals of an application.               ## Use Cases [\#](\#use-cases ""Permalink to this headline"")          Best practices and built-in implementations for common LangChain use cases:          - [Autonomous Agents](https://python.langchain.com/en/latest/use_cases/autonomous_agents.html): Autonomous agents are long-running agents that take many steps in an attempt to accomplish an objective. Examples include AutoGPT and BabyAGI.          - [Agent Simulations](https://python.langchain.com/en/latest/use_cases/agent_simulations.html): Putting agents in a sandbox and observing how they interact with each other and react to events can be an effective way to evaluate their long-range reasoning and planning abilities.          - [Personal Assistants](https://python.langchain.com/en/latest/use_cases/personal_assistants.html): One of the primary LangChain use cases. Personal assistants need to take actions, remember interactions, and have knowledge about your data.          - [Question Answering](https://python.langchain.com/en/latest/use_cases/question_answering.html): Another common LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.          - [Chatbots](https://python.langchain.com/en/latest/use_cases/chatbots.html): Language models love to chat, making this a very natural use of them.          - [Querying Tabular Data](https://python.langchain.com/en/latest/use_cases/tabular.html): Recommended reading if you want to use language models to query structured data (CSVs, SQL, dataframes, etc).          - [Code Understanding](https://python.langchain.com/en/latest/use_cases/code.html): Recommended reading if you want to use language models to analyze code.          - [Interacting with APIs](https://python.langchain.com/en/latest/use_cases/apis.html): Enabling language models to interact with APIs is extremely powerful. It gives them access to up-to-date information and allows them to take actions.          - [Extraction]("

It provides a visual interface known as a ""board"" where users can create lists and cards to represent their tasks and activities.  The TrelloLoader allows you to load cards from a Trello board and is implemented on top of [py-trello](https://pypi.org/project/py-trello/)  This currently supports api_key/token only.  - Credentials generation: [https://trello.com/power-ups/admin/](https://trello.com/power-ups/admin/)  - Click in the manual token generation link to get the token.  To specify the API key and token you can either set the environment variables TRELLO_API_KEY and TRELLO_TOKEN or you can pass api_key and token directly into the from_credentials convenience constructor method.  This loader allows you to provide the board name to pull in the corresponding cards into Document objects.  Notice that the board ""name"" is also called ""title"" in oficial documentation:  [https://support.atlassian.com/trello/docs/changing-a-boards-title-and-description/](https://support.atlassian.com/trello/docs/changing-a-boards-title-and-description/)  You can also specify several load parameters to include / remove different fields both from the document page_content properties and metadata.  ##Features[​](#features) - Load cards from a Trello board. - Filter cards based on their status (open or closed). - Include card names, comments, and checklists in the loaded documents. - Customize the additional metadata fields to include in the document.

Unstructured currently supports loading of text files, powerpoints, html, pdfs, images, and more.  # # Install package pip install ""unstructured[all-docs]""  # # Install other dependencies # # https://github.com/Unstructured-IO/unstructured/blob/main/docs/source/installing.rst # !brew install libmagic # !brew install poppler # !brew install tesseract # # If parsing xml / html documents: # !brew install libxml2 # !brew install libxslt  # import nltk # nltk.download('punkt')  from langchain.document_loaders import UnstructuredFileLoader  loader = UnstructuredFileLoader(""./example_data/state_of_the_union.txt"")  docs = loader.load()  docs[0].page_content[:400]      'Madam Speaker, Madam Vice President, our First Lady and Second Gentleman.

Currently supported strategies are ""hi_res"" (the default) and ""fast"". Hi res partitioning strategies are more accurate, but take longer to process. Fast strategies partition the document more quickly, but trade-off accuracy. Not all document types have separate hi res and fast partitioning strategies. For those document types, the strategy kwarg is ignored. In some cases, the high res strategy will fallback to fast if there is a dependency missing (i.e. a model for document partitioning). You can see how to apply a strategy to an UnstructuredFileLoader below.  from langchain.document_loaders import UnstructuredFileLoader  loader = UnstructuredFileLoader(     ""layout-parser-paper-fast.pdf"", strategy=""fast"", mode=""elements"" )  docs = loader.load()  docs[:5]      [Document(page_content='1', lookup_str='', metadata={'source': 'layout-parser-paper-fast.pdf', 'filename': 'layout-parser-paper-fast.pdf', 'page_number': 1, 'category': 'UncategorizedText'}, lookup_index=0),      Document(page_content='2', lookup_str='', metadata={'source': 'layout-parser-paper-fast.pdf', 'filename': 'layout-parser-paper-fast.pdf', 'page_number': 1, 'category': 'UncategorizedText'}, lookup_index=0),      Document(page_content='0', lookup_str='', metadata={'source': 'layout-parser-paper-fast.pdf', 'filename': 'layout-parser-paper-fast.pdf', 'page_number': 1, 'category': 'UncategorizedText'}, lookup_index=0),      Document(page_content='2', lookup_str='', metadata={'source': 'layout-parser-paper-fast.pdf', 'filename': 'layout-parser-paper-fast.pdf', 'page_number': 1, 'category': 'UncategorizedText'}, lookup_index=0),      Document(page_content='n', lookup_str='', metadata={'source': 'layout-parser-paper-fast.pdf', 'filename': 'layout-parser-paper-fast.pdf', 'page_number': 1, 'category': 'Title'}, lookup_index=0)]  ##PDF Example[​](#pdf-example) Processing PDF documents works exactly the same way. Unstructured detects the file type and extracts the same types of elements. Modes of operation are  - single all the text from all elements are combined into one (default) - elements maintain individual elements - paged texts from each page are only combined wget  https://raw.githubusercontent.com/Unstructured-IO/unstructured/main/example-docs/layout-parser-paper.pdf -P ""../../""  loader = UnstructuredFileLoader(     ""./example_data/layout-parser-paper.pdf"", mode=""elements"" )  docs = loader.load()  docs[:5]      [Document(page_content='LayoutParser : A Unified Toolkit for Deep Learning Based Document Image Analysis', lookup_str='', metadata={'source': '../../layout-parser-paper.pdf'}, lookup_index=0),      Document(page_content='Zejiang Shen 1 ( (ea)\n ), Ruochen Zhang 2 , Melissa Dell 3 , Benjamin Charles Germain Lee 4 , Jacob Carlson 3 , and Weining Li 5', lookup_str='', metadata={'source': '../../layout-parser-paper.pdf'}, lookup_index=0),      Document(page_content='Allen Institute for AI shannons@allenai.org', lookup_str='', metadata={'source': '../../layout-parser-paper.pdf'}, lookup_index=0),      Document(page_content='Brown University ruochen zhang@brown.edu', lookup_str='', metadata={'source': '../../layout-parser-paper.pdf'}, lookup_index=0),    "

Beautiful Soup | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_transformers/beautiful_soup,langchain_docs,"Main:  #Beautiful Soup [Beautiful Soup](https://www.crummy.com/software/BeautifulSoup/) is a Python package for parsing HTML and XML documents (including having malformed markup, i.e. non-closed tags, so named after tag soup). It creates a parse tree for parsed pages that can be used to extract data from HTML,[3] which is useful for web scraping.  Beautiful Soup offers fine-grained control over HTML content, enabling specific tag extraction, removal, and content cleaning.  It's suited for cases where you want to extract specific information and clean up the HTML content according to your needs.  For example, we can scrape text content within <p>, <li>, <div>, and <a> tags from the HTML content:  - <p>: The paragraph tag. It defines a paragraph in HTML and is used to group together related sentences and/or phrases. - <li>: The list item tag. It is used within ordered (<ol>) and unordered (<ul>) lists to define individual items within the list. - <div>: The division tag. It is a block-level element used to group other inline or block-level elements. - <a>: The anchor tag. It is used to define hyperlinks. from langchain.document_loaders import AsyncChromiumLoader from langchain.document_transformers import BeautifulSoupTransformer  # Load HTML loader = AsyncChromiumLoader([""https://www.wsj.com""]) html = loader.load()  # Transform bs_transformer = BeautifulSoupTransformer() docs_transformed = bs_transformer.transform_documents(     html, tags_to_extract=[""p"", ""li"", ""div"", ""a""] )  docs_transformed[0].page_content[0:500]      'Conservative legal activists are challenging Amazon, Comcast and others using many of the same tools that helped kill affirmative-action programs in colleges.1,2099 min read U.S. stock indexes fell and government-bond prices climbed, after Moody’s lowered credit ratings for 10 smaller U.S. banks and said it was reviewing ratings for six larger ones.

You need to install two libraries to use this parser:  %pip install google-cloud-documentai-toolbox  First, you need to set up a Google Cloud Storage (GCS) bucket and create your own Optical Character Recognition (OCR) processor as described here: [https://cloud.google.com/document-ai/docs/create-processor](https://cloud.google.com/document-ai/docs/create-processor)  The GCS_OUTPUT_PATH should be a path to a folder on GCS (starting with gs://) and a PROCESSOR_NAME should look like projects/PROJECT_NUMBER/locations/LOCATION/processors/PROCESSOR_ID or projects/PROJECT_NUMBER/locations/LOCATION/processors/PROCESSOR_ID/processorVersions/PROCESSOR_VERSION_ID. You can get it either programmatically or copy from the Prediction endpoint section of the Processor details tab in the Google Cloud Console.  GCS_OUTPUT_PATH = ""gs://BUCKET_NAME/FOLDER_PATH"" PROCESSOR_NAME = ""projects/PROJECT_NUMBER/locations/LOCATION/processors/PROCESSOR_ID""  from langchain.document_loaders.blob_loaders import Blob from langchain.document_loaders.parsers import DocAIParser  Now, create a DocAIParser.  parser = DocAIParser(     location=""us"", processor_name=PROCESSOR_NAME, gcs_output_path=GCS_OUTPUT_PATH )  For this example, you can use an Alphabet earnings report that's uploaded to a public GCS bucket.  [2022Q1_alphabet_earnings_release.pdf](https://storage.googleapis.com/cloud-samples-data/gen-app-builder/search/alphabet-investor-pdfs/2022Q1_alphabet_earnings_release.pdf)  Pass the document to the lazy_parse() method to  blob = Blob(     path=""gs://cloud-samples-data/gen-app-builder/search/alphabet-investor-pdfs/2022Q1_alphabet_earnings_release.pdf"" )  We'll get one document per page, 11 in total:  docs = list(parser.lazy_parse(blob)) print(len(docs))      11  You can run end-to-end parsing of a blob one-by-one. If you have many documents, it might be a better approach to batch them together and maybe even detach parsing from handling the results of parsing.  operations = parser.docai_parse([blob]) print([op.operation.name for op in operations])      ['projects/543079149601/locations/us/operations/16447136779727347991']  You can check whether operations are finished:  parser.is_running(operations)      True  And when they're finished, you can parse the results:  parser.is_running(operations)      False  results = parser.get_results(operations) print(results[0])      DocAIParsingResults(source_path='gs://vertex-pgt/examples/goog-exhibit-99-1-q1-2023-19.pdf', parsed_path='gs://vertex-pgt/test/run1/16447136779727347991/0')  And now we can finally generate Documents from parsed results:  docs = list(parser.parse_from_results(results))  print(len(docs))      11    "

OpenAI metadata tagger | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/document_transformers/openai_metadata_tagger,langchain_docs,"Main:  On this page #OpenAI metadata tagger It can often be useful to tag ingested documents with structured metadata, such as the title, tone, or length of a document, to allow for a more targeted similarity search later. However, for large numbers of documents, performing this labelling process manually can be tedious.  The OpenAIMetadataTagger document transformer automates this process by extracting metadata from each provided document according to a provided schema. It uses a configurable OpenAI Functions-powered chain under the hood, so if you pass a custom LLM instance, it must be an OpenAI model with functions support.  Note: This document transformer works best with complete documents, so it's best to run it first with whole documents before doing any other splitting or processing!  For example, let's say you wanted to index a set of movie reviews. You could initialize the document transformer with a valid JSON Schema object as follows:  from langchain.chat_models import ChatOpenAI from langchain.document_transformers.openai_functions import create_metadata_tagger from langchain.schema import Document  schema = {     ""properties"": {         ""movie_title"": {""type"": ""string""},         ""critic"": {""type"": ""string""},         ""tone"": {""type"": ""string"", ""enum"": [""positive"", ""negative""]},         ""rating"": {             ""type"": ""integer"",             ""description"": ""The number of stars the critic rated the movie"",         },     },     ""required"": [""movie_title"", ""critic"", ""tone""], }  # Must be an OpenAI model that supports functions llm = ChatOpenAI(temperature=0, model=""gpt-3.5-turbo-0613"")  document_transformer = create_metadata_tagger(metadata_schema=schema, llm=llm)  You can then simply pass the document transformer a list of documents, and it will extract metadata from the contents:  original_documents = [     Document(         page_content=""Review of The Bee Movie\nBy Roger Ebert\n\nThis is the greatest movie ever made. 4 out of 5 stars.""     ),     Document(         page_content=""Review of The Godfather\nBy Anonymous\n\nThis movie was super boring. 1 out of 5 stars."",         metadata={""reliable"": False},     ), ]  enhanced_documents = document_transformer.transform_documents(original_documents)  import json  print(     *[d.page_content + ""\n\n"" + json.dumps(d.metadata) for d in enhanced_documents],     sep=""\n\n---------------\n\n"", )      Review of The Bee Movie     By Roger Ebert          This is the greatest movie ever made. 4 out of 5 stars.          {""movie_title"": ""The Bee Movie"", ""critic"": ""Roger Ebert"", ""tone"": ""positive"", ""rating"": 4}          ---------------          Review of The Godfather     By Anonymous          This movie was super boring. 1 out of 5 stars.          {""movie_title"": ""The Godfather"", ""critic"": ""Anonymous"", ""tone"": ""negative"", ""rating"": 1, ""reliable"": false}  The new documents can then be further processed by a text splitter before being loaded into a vector store. Extracted fields will not overwrite existing metadata.  You can also initialize the document transformer with a Pydantic schema:  from typing import Literal  from pydantic import BaseModel, Field   class Properties(BaseModel):     movie_title: str     critic: str     tone: Literal[""positive"", ""negative""]     rating: int = Field(description=""Rating out of 5 stars"")   document_transformer = create_metadata_tagger(Properties, llm) enhanced_documents = document_transformer.transform_documents(original_documents)  print(     *[d.page_content + ""\n\n"" + json.dumps(d.metadata) for d in enhanced_documents],     sep=""\n\n---------------\n\n"", )      Review of The Bee Movie     By Roger Ebert          This is the greatest movie ever made. 4 out of 5 stars.          {""movie_title"": ""The Bee Movie"", ""critic"": ""Roger Ebert"", ""tone"": ""positive"", ""rating"": 4}          ---------------          Review of The Godfather     By Anonymous          This movie was super boring. 1 out of 5 stars.          {""movie_title"": ""The Godfather"", ""critic"": ""Anonymous"", ""tone"": ""negative"", ""rating"": 1, ""reliable"": false}  ##Customization[​](#customization) You can pass the underlying tagging chain the standard LLMChain arguments in the document transformer constructor. For example, if you wanted to ask the LLM to focus specific details in the input documents, or extract metadata in a certain style, you could pass in a custom prompt:  from langchain.prompts import ChatPromptTemplate  prompt = ChatPromptTemplate.from_template(     """"""Extract relevant information from the following text. Anonymous critics are actually Roger Ebert.  {input} """""" )  document_transformer = create_metadata_tagger(schema, llm, prompt=prompt) enhanced_documents = document_transformer.transform_documents(original_documents)  print(     *[d.page_content + ""\n\n"" + json.dumps(d.metadata) for d in enhanced_documents],     sep=""\n\n---------------\n\n"", )      Review of The Bee Movie     By Roger Ebert          This is the greatest movie ever made. 4 out of 5 stars.          {""movie_title"": ""The Bee Movie"", ""critic"": ""Roger Ebert"", ""tone"": ""positive"", ""rating"": 4}          ---------------          Review of The Godfather     By Anonymous          This movie was super boring. 1 out of 5 stars.          {""movie_title"": ""The Godfather"", ""critic"": ""Roger Ebert"", ""tone"": ""negative"", ""rating"": 1, ""reliable"": false}    "
LLMs | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/llms/,langchain_docs,"Main:  Skip to main content  🦜️🔗 LangChain  Search CTRLK ComponentsLLMs On this page LLMs Features (natively supported)​ All LLMs implement the Runnable interface, which comes with default implementations of all methods, ie. ainvoke, batch, abatch, stream, astream. This gives all LLMs basic support for async, streaming and batch, which by default is implemented as below:  Async support defaults to calling the respective sync method in asyncio's default thread pool executor. This lets other async functions in your application make progress while the LLM is being executed, by moving this call to a background thread. Streaming support defaults to returning an Iterator (or AsyncIterator in the case of async streaming) of a single value, the final result returned by the underlying LLM provider. This obviously doesn't give you token-by-token streaming, which requires native support from the LLM provider, but ensures your code that expects an iterator of tokens can work for any of our LLM integrations. Batch support defaults to calling the underlying LLM in parallel for each input by making use of a thread pool executor (in the sync batch case) or asyncio.gather (in the async batch case). The concurrency can be controlled with the max_concurrency key in RunnableConfig. Each LLM integration can optionally provide native implementations for async, streaming or batch, which, for providers that support it, can be more efficient.

APIs act as the ""front door"" for applications to access data, business logic, or functionality from your backend services. Using API Gateway, you can create RESTful APIs and WebSocket APIs that enable real-time two-way communication applications. API Gateway supports containerized and serverless workloads, as well as web applications.  API Gateway handles all the tasks involved in accepting and processing up to hundreds of thousands of concurrent API calls, including traffic management, CORS support, authorization and access control, throttling, monitoring, and API version management. API Gateway has no minimum fees or startup costs. You pay for the API calls you receive and the amount of data transferred out and, with the API Gateway tiered pricing model, you can reduce your cost as your API usage scales.  ##LLM[​](#llm) from langchain.llms import AmazonAPIGateway  api_url = ""https://<api_gateway_id>.execute-api.<region>.amazonaws.com/LATEST/HF"" llm = AmazonAPIGateway(api_url=api_url)  # These are sample parameters for Falcon 40B Instruct Deployed from Amazon SageMaker JumpStart parameters = {     ""max_new_tokens"": 100,     ""num_return_sequences"": 1,     ""top_k"": 50,     ""top_p"": 0.95,     ""do_sample"": False,     ""return_full_text"": True,     ""temperature"": 0.2, }  prompt = ""what day comes after Friday?"" llm.model_kwargs = parameters llm(prompt)      'what day comes after Friday?\nSaturday'  ##Agent[​](#agent) from langchain.agents import AgentType, initialize_agent, load_tools  parameters = {     ""max_new_tokens"": 50,     ""num_return_sequences"": 1,     ""top_k"": 250,     ""top_p"": 0.25,     ""do_sample"": False,     ""temperature"": 0.1, }  llm.model_kwargs = parameters  # Next, let's load some tools to use.

Azure OpenAI | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/llms/azure_openai,langchain_docs,"Main:  On this page #Azure OpenAI This notebook goes over how to use Langchain with [Azure OpenAI](https://aka.ms/azure-openai).  The Azure OpenAI API is compatible with OpenAI's API. The openai Python package makes it easy to use both OpenAI and Azure OpenAI. You can call Azure OpenAI the same way you call OpenAI with the exceptions noted below.  ##API configuration[​](#api-configuration) You can configure the openai package to use Azure OpenAI using environment variables. The following is for bash:  # Set this to `azure` export OPENAI_API_TYPE=azure # The API version you want to use: set this to `2023-05-15` for the released version. export OPENAI_API_VERSION=2023-05-15 # The base URL for your Azure OpenAI resource.  You can find this in the Azure portal under your Azure OpenAI resource. export OPENAI_API_BASE=https://your-resource-name.openai.azure.com # The API key for your Azure OpenAI resource.  You can find this in the Azure portal under your Azure OpenAI resource. export OPENAI_API_KEY=<your Azure OpenAI API key>  Alternatively, you can configure the API right within your running Python environment:  import os os.environ[""OPENAI_API_TYPE""] = ""azure""  ##Azure Active Directory Authentication[​](#azure-active-directory-authentication) There are two ways you can authenticate to Azure OpenAI:  - API Key - Azure Active Directory (AAD) Using the API key is the easiest way to get started. You can find your API key in the Azure portal under your Azure OpenAI resource.  However, if you have complex security requirements - you may want to use Azure Active Directory. You can find more information on how to use AAD with Azure OpenAI [here](https://learn.microsoft.com/en-us/azure/ai-services/openai/how-to/managed-identity).  If you are developing locally, you will need to have the Azure CLI installed and be logged in. You can install the Azure CLI [here](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli). Then, run az login to log in.  Add a role an Azure role assignment Cognitive Services OpenAI User scoped to your Azure OpenAI resource. This will allow you to get a token from AAD to use with Azure OpenAI. You can grant this role assignment to a user, group, service principal, or managed identity. For more information about Azure OpenAI RBAC roles see [here](https://learn.microsoft.com/en-us/azure/ai-services/openai/how-to/role-based-access-control).  To use AAD in Python with LangChain, install the azure-identity package. Then, set OPENAI_API_TYPE to azure_ad. Next, use the DefaultAzureCredential class to get a token from AAD by calling get_token as shown below. Finally, set the OPENAI_API_KEY environment variable to the token value.  import os from azure.identity import DefaultAzureCredential  # Get the Azure Credential credential = DefaultAzureCredential()  # Set the API type to `azure_ad` os.environ[""OPENAI_API_TYPE""] = ""azure_ad"" # Set the API_KEY to the token from the Azure credential os.environ[""OPENAI_API_KEY""] = credential.get_token(""https://cognitiveservices.azure.com/.default"").token  The DefaultAzureCredential class is an easy way to get started with AAD authentication. You can also customize the credential chain if necessary. In the example shown below, we first try Managed Identity, then fall back to the Azure CLI. This is useful if you are running your code in Azure, but want to develop locally.  from azure.identity import ChainedTokenCredential, ManagedIdentityCredential, AzureCliCredential  credential = ChainedTokenCredential(     ManagedIdentityCredential(),     AzureCliCredential() )  ##Deployments[​](#deployments) With Azure OpenAI, you set up your own deployments of the common GPT-3 and Codex models. When calling the API, you need to specify the deployment you want to use.  Note: These docs are for the Azure text completion models. Models like GPT-4 are chat models.

The game was won by the San Francisco 49ers, who defeated the San Diego Chargers by a score of 49-26. Therefore, the San Francisco 49ers won the Super Bowl in the year Justin Bieber was born.'    "

Peyton Manning? Aaron Rodgers? Or maybe even Andrew Luck?          Well, let's look at some stats to decide.          First, let's talk about touchdowns. Who's thrown the most touchdowns this season?          (pause for dramatic effect)          It's... Aaron Rodgers! With 28 touchdowns, he's leading the league in that category.          But what about interceptions? Who's thrown the fewest picks?          (drumroll)          It's... Tom Brady! With only 4 interceptions, he's got the fewest picks in the league.          Now, let's talk about passer rating. Who's got the highest passer rating this season?          (pause for suspense)          It's... Peyton Manning! With a rating of 114.2, he's been lights out this season.          But what about wins? Who's got the most wins this season?          (drumroll)          It's... Andrew Luck! With 8 wins, he's got the most victories this season.          So, there you have it folks. According to these stats, the best quarterback in the NFL this season is... (drumroll) Aaron Rodgers!          But wait, there's more! Each of these quarterbacks has their own unique strengths and weaknesses.          Tom Brady is a master of the short pass, but can struggle with deep balls. Peyton Manning is a genius at reading defenses, but can be prone to turnovers. Aaron Rodgers has a cannon for an arm, but can be inconsistent at times. Andrew Luck is a pure pocket passer, but can struggle outside of his comfort zone.          So, who's the best quarterback in the NFL? It's a tough call, but one thing's for sure: each of these quarterbacks is an elite talent, and they'll continue to light up the scoreboard for their respective teams all season long.  # Calling multiple prompts output = llm.generate(     [         ""Who's the best cricket player in 2016?"",         ""Who's the best basketball player in the league?"",     ] ) print(output.generations)      [[Generation(text='\nasked Dec 28, 2016 in Sports by anonymous\nWho is the best cricket player in 2016?\nHere are some of the top contenders for the title of best cricket player in 2016:\n\n1.

Hugging Face Local Pipelines | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/llms/huggingface_pipelines,langchain_docs,"Main:  On this page #Hugging Face Local Pipelines Hugging Face models can be run locally through the HuggingFacePipeline class.  The [Hugging Face Model Hub](https://huggingface.co/models) hosts over 120k models, 20k datasets, and 50k demo apps (Spaces), all open source and publicly available, in an online platform where people can easily collaborate and build ML together.  These can be called from LangChain either through this local pipeline wrapper or by calling their hosted inference endpoints through the HuggingFaceHub class. For more information on the hosted pipelines, see the [HuggingFaceHub](/docs/integrations/llms/huggingface_hub.html) notebook.  To use, you should have the transformers python [package installed](https://pypi.org/project/transformers/), as well as [pytorch](https://pytorch.org/get-started/locally/). You can also install xformer for a more memory-efficient attention implementation.  %pip install transformers --quiet  ###Model Loading[​](#model-loading) Models can be loaded by specifying the model parameters using the from_model_id method.  from langchain.llms.huggingface_pipeline import HuggingFacePipeline  hf = HuggingFacePipeline.from_model_id(     model_id=""gpt2"",     task=""text-generation"",     pipeline_kwargs={""max_new_tokens"": 10}, )  They can also be loaded by passing in an existing transformers pipeline directly  from langchain.llms.huggingface_pipeline import HuggingFacePipeline from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline  model_id = ""gpt2"" tokenizer = AutoTokenizer.from_pretrained(model_id) model = AutoModelForCausalLM.from_pretrained(model_id) pipe = pipeline(""text-generation"", model=model, tokenizer=tokenizer, max_new_tokens=10) hf = HuggingFacePipeline(pipeline=pipe)  ###Create Chain[​](#create-chain) With the model loaded into memory, you can compose it with a prompt to form a chain.  from langchain.prompts import PromptTemplate  template = """"""Question: {question}  Answer: Let's think step by step."""""" prompt = PromptTemplate.from_template(template)  chain = prompt | hf  question = ""What is electroencephalography?""  print(chain.invoke({""question"": question}))  ###GPU Inference[​](#gpu-inference) When running on a machine with GPU, you can specify the device=n parameter to put the model on the specified device. Defaults to -1 for CPU inference.  If you have multiple-GPUs and/or the model is too large for a single GPU, you can specify device_map=""auto"", which requires and uses the [Accelerate](https://huggingface.co/docs/accelerate/index) library to automatically determine how to load the model weights.  Note: both device and device_map should not be specified together and can lead to unexpected behavior.  gpu_llm = HuggingFacePipeline.from_model_id(     model_id=""gpt2"",     task=""text-generation"",     device=0,  # replace with device_map=""auto"" to use the accelerate library.     pipeline_kwargs={""max_new_tokens"": 10}, )  gpu_chain = prompt | gpu_llm  question = ""What is electroencephalography?""  print(gpu_chain.invoke({""question"": question}))  ###Batch GPU Inference[​](#batch-gpu-inference) If running on a device with GPU, you can also run inference on the GPU in batch mode.  gpu_llm = HuggingFacePipeline.from_model_id(     model_id=""bigscience/bloom-1b7"",     task=""text-generation"",     device=0,  # -1 for CPU     batch_size=2,  # adjust as needed based on GPU map and model size.     model_kwargs={""temperature"": 0, ""max_length"": 64}, )  gpu_chain = prompt | gpu_llm.bind(stop=[""\n\n""])  questions = [] for i in range(4):     questions.append({""question"": f""What is the number {i} in french?""})  answers = gpu_chain.batch(questions) for answer in answers:     print(answer)    "

You can follow most of the instructions in the repository itself but there are some windows specific instructions which might be useful.  Requirements to install the llama-cpp-python,  git python cmake Visual Studio Community (make sure you install this with the following settings) Desktop development with C++ Python development Linux embedded development with C++ Clone git repository recursively to get llama.cpp submodule as well git clone --recursive -j8 https://github.com/abetlen/llama-cpp-python.git  Open up command Prompt (or anaconda prompt if you have it installed), set up environment variables to install. Follow this if you do not have a GPU, you must set both of the following variables. set FORCE_CMAKE=1 set CMAKE_ARGS=-DLLAMA_CUBLAS=OFF  You can ignore the second environment variable if you have an NVIDIA GPU.  Compiling and installing​ In the same command prompt (anaconda prompt) you set the variables, you can cd into llama-cpp-python directory and run the following commands.  python setup.py clean python setup.py install  Usage​ Make sure you are following all instructions to install all necessary model files.  You don't need an API_TOKEN as you will run the LLM locally.  It is worth understanding which models are suitable to be used on the desired machine.  TheBloke's Hugging Face models have a Provided files section that exposes the RAM required to run models of different quantisation sizes and methods (eg: Llama2-7B-Chat-GGUF).

You also could check Activity Monitor by watching the GPU usage of the process, the CPU usage will drop dramatically after turn on n_gpu_layers=1.  For the first call to the LLM, the performance may be slow due to the model compilation in Metal GPU.  Grammars​ We can use grammars to constrain model outputs and sample tokens based on the rules defined in them.  To demonstrate this concept, we've included sample grammar files, that will be used in the examples below.  Creating gbnf grammar files can be time-consuming, but if you have a use-case where output schemas are important, there are two tools that can help:  Online grammar generator app that converts TypeScript interface definitions to gbnf file. Python script for converting json schema to gbnf file. You can for example create pydantic object, generate its JSON schema using .schema_json() method, and then use this script to convert it to gbnf file. In the first example, supply the path to the specified json.gbnf file in order to produce JSON:  n_gpu_layers = 1  # Metal set to 1 is enough. n_batch = 512  # Should be between 1 and n_ctx, consider the amount of RAM of your Apple Silicon Chip. # Make sure the model path is correct for your system! llm = LlamaCpp(     model_path=""/Users/rlm/Desktop/Code/llama.cpp/models/openorca-platypus2-13b.gguf.q4_0.bin"",     n_gpu_layers=n_gpu_layers,     n_batch=n_batch,     f16_kv=True,  # MUST set to True, otherwise you will run into problem after a couple of calls     callback_manager=callback_manager,     verbose=True,  # Verbose is required to pass to the callback manager     grammar_path=""/Users/rlm/Desktop/Code/langchain-main/langchain/libs/langchain/langchain/llms/grammars/json.gbnf"", )  result = llm(""Describe a person in JSON format:"")      {       ""name"": ""John Doe"",       ""age"": 34,       """": {         ""title"": ""Software Developer"",         ""company"": ""Google""       },       ""interests"": [         ""Sports"",         ""Music"",         ""Cooking""       ],       ""address"": {         ""street_number"": 123,         ""street_name"": ""Oak Street"",         ""city"": ""Mountain View"",         ""state"": ""California"",         ""postal_code"": 94040       }}           llama_print_timings:        load time =   357.51 ms     llama_print_timings:      sample time =  1213.30 ms /   144 runs   (    8.43 ms per token,   118.68 tokens per second)     llama_print_timings: prompt eval time =   356.78 ms /     9 tokens (   39.64 ms per token,    25.23 tokens per second)     llama_print_timings:        eval time =  3947.16 ms /   143 runs   (   27.60 ms per token,    36.23 tokens per second)     llama_print_timings:       total time =  5846.21 ms  We can also supply list.gbnf to return a list:  n_gpu_layers = 1 n_batch = 512 llm = LlamaCpp(     model_path=""/Users/rlm/Desktop/Code/llama.cpp/models/openorca-platypus2-13b.gguf.q4_0.bin"",     n_gpu_layers=n_gpu_layers,     n_batch=n_batch,     f16_kv=True,  # MUST set to True, otherwise you will run into problem after a couple of calls     callback_manager=callback_manager,     verbose=True,     grammar_path=""/Users/rlm/Desktop/Code/langchain-main/langchain/libs/langchain/langchain/llms/grammars/list.gbnf"", )  result = llm(""List of top-3 my favourite books:"")      [""The Catcher in the Rye"", ""Wuthering Heights"", ""Anna Karenina""]            llama_print_timings:        load time =   322.34 ms     llama_print_timings:      sample time =   232.60 ms /    26 runs   (    8.95 ms per token,   111.78 tokens per second)     llama_print_timings: prompt eval time =   321.90 ms /    11 tokens (   29.26 ms per token,    34.17 tokens per second)     llama_print_timings:        eval time =   680.82 ms /    25 runs   (   27.23 ms per token,    36.72 tokens per second)     llama_print_timings:       total time =  1295.27 ms  Previous KoboldAI API Next LLM Caching integrations Community Discord Twitter GitHub Python JS/TS More Homepage Blog Copyright © 2023 LangChain, Inc.

This can either be passed in to a momento.CacheClient if you'd like to instantiate that directly, as a named parameter auth_token to MomentoChatMessageHistory.from_client_params, or can just be set as an environment variable MOMENTO_AUTH_TOKEN.  from datetime import timedelta  from langchain.cache import MomentoCache  cache_name = ""langchain"" ttl = timedelta(days=1) set_llm_cache(MomentoCache.from_client_params(cache_name, ttl))  # The first time, it is not yet in cache, so it should take longer llm(""Tell me a joke"")      CPU times: user 40.7 ms, sys: 16.5 ms, total: 57.2 ms     Wall time: 1.73 s          '\n\nWhy did the chicken cross the road?\n\nTo get to the other side!'  # The second time it is, so it goes faster # When run in the same region as the cache, latencies are single digit ms llm(""Tell me a joke"")      CPU times: user 3.16 ms, sys: 2.98 ms, total: 6.14 ms     Wall time: 57.9 ms          '\n\nWhy did the chicken cross the road?\n\nTo get to the other side!'  ##SQLAlchemy Cache[​](#sqlalchemy-cache) You can use SQLAlchemyCache to cache with any SQL database supported by SQLAlchemy.  # from langchain.cache import SQLAlchemyCache # from sqlalchemy import create_engine  # engine = create_engine(""postgresql://postgres:postgres@localhost:5432/postgres"") # set_llm_cache(SQLAlchemyCache(engine))  ###Custom SQLAlchemy Schemas[​](#custom-sqlalchemy-schemas) # You can define your own declarative SQLAlchemyCache child class to customize the schema used for caching. For example, to support high-speed fulltext prompt indexing with Postgres, use:  from langchain.cache import SQLAlchemyCache from sqlalchemy import Column, Computed, Index, Integer, Sequence, String, create_engine from sqlalchemy.ext.declarative import declarative_base from sqlalchemy_utils import TSVectorType  Base = declarative_base()   class FulltextLLMCache(Base):  # type: ignore     """"""Postgres table for fulltext-indexed LLM Cache""""""      __tablename__ = ""llm_cache_fulltext""     id = Column(Integer, Sequence(""cache_id""), primary_key=True)     prompt = Column(String, nullable=False)     llm = Column(String, nullable=False)     idx = Column(Integer)     response = Column(String)     prompt_tsv = Column(         TSVectorType(),         Computed(""to_tsvector('english', llm || ' ' || prompt)"", persisted=True),     )     __table_args__ = (         Index(""idx_fulltext_prompt_tsv"", prompt_tsv, postgresql_using=""gin""),     )   engine = create_engine(""postgresql://postgres:postgres@localhost:5432/postgres"") set_llm_cache(SQLAlchemyCache(engine, FulltextLLMCache))  ##Cassandra caches[​](#cassandra-caches) You can use Cassandra / Astra DB through CQL for caching LLM responses, choosing from the exact-match CassandraCache or the (vector-similarity-based) CassandraSemanticCache.  Let's see both in action in the following cells.  ####Connect to the DB[​](#connect-to-the-db) First you need to establish a Session to the DB and to specify a keyspace for the cache table(s). The following gets you connected to Astra DB through CQL (see e.g. [here](https://cassio.org/start_here/#vector-database) for more backends and connection options).  import getpass  keyspace = input(""\nKeyspace name? "") ASTRA_DB_APPLICATION_TOKEN = getpass.getpass('\nAstra DB Token (""AstraCS:..."") ') ASTRA_DB_SECURE_BUNDLE_PATH = input(""Full path to your Secure Connect Bundle?

CPU times: user 10.9 ms, sys: 17 µs, total: 10.9 ms     Wall time: 461 ms  ##Astra DB Caches[​](#astra-db-caches) You can easily use [Astra DB](https://docs.datastax.com/en/astra/home/astra.html) as an LLM cache, with either the ""exact"" or the ""semantic-based"" cache.  Make sure you have a running database (it must be a Vector-enabled database to use the Semantic cache) and get the required credentials on your Astra dashboard:  - the API Endpoint looks like https://01234567-89ab-cdef-0123-456789abcdef-us-east1.apps.astra.datastax.com - the Token looks like AstraCS:6gBhNmsk135.... import getpass  ASTRA_DB_API_ENDPOINT = input(""ASTRA_DB_API_ENDPOINT = "") ASTRA_DB_APPLICATION_TOKEN = getpass.getpass(""ASTRA_DB_APPLICATION_TOKEN = "")      ASTRA_DB_API_ENDPOINT =  https://01234567-89ab-cdef-0123-456789abcdef-us-east1.apps.astra.datastax.com     ASTRA_DB_APPLICATION_TOKEN =  ········  ###Astra DB exact LLM cache[​](#astra-db-exact-llm-cache) This will avoid invoking the LLM when the supplied prompt is exactly the same as one encountered already:  from langchain.cache import AstraDBCache from langchain.globals import set_llm_cache  set_llm_cache(     AstraDBCache(         api_endpoint=ASTRA_DB_API_ENDPOINT,         token=ASTRA_DB_APPLICATION_TOKEN,     ) )  print(llm(""Is a true fakery the same as a fake truth?""))                There is no definitive answer to this question as it depends on the interpretation of the terms ""true fakery"" and ""fake truth"". However, one possible interpretation is that a true fakery is a counterfeit or imitation that is intended to deceive, whereas a fake truth is a false statement that is presented as if it were true.     CPU times: user 70.8 ms, sys: 4.13 ms, total: 74.9 ms     Wall time: 2.06 s  print(llm(""Is a true fakery the same as a fake truth?""))

There is no definitive answer to this question since it presupposes a great deal about the nature of truth itself, which is a matter of considerable philosophical debate. It is possible, however, to construct scenarios in which something could be considered true despite being false, such as if someone sincerely believes something to be true even though it is not.     CPU times: user 65.6 ms, sys: 15.3 ms, total: 80.9 ms     Wall time: 2.72 s  print(llm(""Is is possible that something false can be also true?""))

In the example below, even though global caching is enabled, we turn it off for a specific LLM  llm = OpenAI(model_name=""text-davinci-002"", n=2, best_of=2, cache=False)  llm(""Tell me a joke"")      CPU times: user 5.8 ms, sys: 2.71 ms, total: 8.51 ms     Wall time: 745 ms          '\n\nWhy did the chicken cross the road?\n\nTo get to the other side!'  llm(""Tell me a joke"")      CPU times: user 4.91 ms, sys: 2.64 ms, total: 7.55 ms     Wall time: 623 ms          '\n\nTwo guys stole a calendar. They got six months each.'  ##Optional Caching in Chains[​](#optional-caching-in-chains) You can also turn off caching for particular nodes in chains. Note that because of certain interfaces, its often easier to construct the chain first, and then edit the LLM afterwards.  As an example, we will load a summarizer map-reduce chain. We will cache results for the map-step, but then not freeze it for the combine step.  llm = OpenAI(model_name=""text-davinci-002"") no_cache_llm = OpenAI(model_name=""text-davinci-002"", cache=False)  from langchain.text_splitter import CharacterTextSplitter  text_splitter = CharacterTextSplitter()  with open(""../../modules/state_of_the_union.txt"") as f:     state_of_the_union = f.read() texts = text_splitter.split_text(state_of_the_union)  from langchain.docstore.document import Document  docs = [Document(page_content=t) for t in texts[:3]] from"

LM Format Enforcer | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/llms/lmformatenforcer_experimental,langchain_docs,"Main:  On this page #LM Format Enforcer [LM Format Enforcer](https://github.com/noamgat/lm-format-enforcer) is a library that enforces the output format of language models by filtering tokens.  It works by combining a character level parser with a tokenizer prefix tree to allow only the tokens which contains sequences of characters that lead to a potentially valid format.  It supports batched generation.  Warning - this module is still experimental  pip install --upgrade lm-format-enforcer > /dev/null  ###Setting up the model[​](#setting-up-the-model) We will start by setting up a LLama2 model and initializing our desired output format. Note that Llama2 [requires approval for access to the models](https://huggingface.co/meta-llama/Llama-2-7b-chat-hf).  import logging  from langchain_experimental.pydantic_v1 import BaseModel  logging.basicConfig(level=logging.ERROR)   class PlayerInformation(BaseModel):     first_name: str     last_name: str     num_seasons_in_nba: int     year_of_birth: int  import torch from transformers import AutoConfig, AutoModelForCausalLM, AutoTokenizer  model_id = ""meta-llama/Llama-2-7b-chat-hf""  device = ""cuda""  if torch.cuda.is_available():     config = AutoConfig.from_pretrained(model_id)     config.pretraining_tp = 1     model = AutoModelForCausalLM.from_pretrained(         model_id,         config=config,         torch_dtype=torch.float16,         load_in_8bit=True,         device_map=""auto"",     ) else:     raise Exception(""GPU not available"") tokenizer = AutoTokenizer.from_pretrained(model_id) if tokenizer.pad_token_id is None:     # Required for batching example     tokenizer.pad_token_id = tokenizer.eos_token_id      /home/noamgat/envs/langchain_experimental/lib/python3.10/site-packages/tqdm/auto.py:21: TqdmWarning: IProgress not found.

DEFAULT_SYSTEM_PROMPT = """"""\ You are a helpful, respectful and honest assistant. Always answer as helpfully as possible, while being safe.  Your answers should not include any harmful, unethical, racist, sexist, toxic, dangerous, or illegal content.

Lets try to enforce proper output.  ##JSONFormer LLM Wrapper[​](#jsonformer-llm-wrapper) Let's try that again, now providing a the Action input's JSON Schema to the model.  from langchain_experimental.llms import LMFormatEnforcer  lm_format_enforcer = LMFormatEnforcer(     json_schema=PlayerInformation.schema(), pipeline=hf_model ) results = lm_format_enforcer.predict(get_prompt(""Michael Jordan"")) print(results)        { ""first_name"": ""Michael"", ""last_name"": ""Jordan"", ""num_seasons_in_nba"": 15, ""year_of_birth"": 1963 }  The output conforms to the exact specification! Free of parsing errors.  This means that if you need to format a JSON for an API call or similar, if you can generate the schema (from a pydantic model or general) you can use this library to make sure that the JSON output is correct, with minimal risk of hallucinations.  ###Batch processing[​](#batch-processing) LMFormatEnforcer also works in batch mode:  prompts = [     get_prompt(name) for name in [""Michael Jordan"", ""Kareem Abdul Jabbar"", ""Tim Duncan""] ] results = lm_format_enforcer.generate(prompts) for generation in results.generations:     print(generation[0].text)        { ""first_name"": ""Michael"", ""last_name"": ""Jordan"", ""num_seasons_in_nba"": 15, ""year_of_birth"": 1963 }       { ""first_name"": ""Kareem"", ""last_name"": ""Abdul-Jabbar"", ""num_seasons_in_nba"": 20, ""year_of_birth"": 1947 }       { ""first_name"": ""Timothy"", ""last_name"": ""Duncan"", ""num_seasons_in_nba"": 19, ""year_of_birth"": 1976 }  ##Regular Expressions[​](#regular-expressions) LMFormatEnforcer has an additional mode, which uses regular expressions to filter the output. Note that it uses [interegular"

Michael Jordan was born on February 17, 1963, in Fort Greene, Brooklyn, New York, USA. Therefore, I cannot provide an answer in the mm/dd/yyyy format as it is not a valid date.

Tree of thoughts (ToT): This extends CoT by exploring multiple reasoning possibilities at each step, creating a tree structure. The search process can be BFS or DFS with each state evaluated by a classifier or majority vote.     3. Using task-specific instructions: For example, ""Write a story outline."" for writing a novel.     4. Human inputs: The agent can receive input from a human operator to perform tasks that require creativity and domain expertise.          These approaches allow the agent to break down complex tasks into manageable subgoals, enabling efficient handling of tasks and improving the quality of final results through self-reflection and refinement.  You can also get logging for tokens.  from langchain.callbacks.base import BaseCallbackHandler from langchain.schema import LLMResult   class GenerationStatisticsCallback(BaseCallbackHandler):     def on_llm_end(self, response: LLMResult, **kwargs) -> None:         print(response.generations[0][0].generation_info)   callback_manager = CallbackManager(     [StreamingStdOutCallbackHandler(), GenerationStatisticsCallback()] )  llm = Ollama(     base_url=""http://localhost:11434"",     model=""llama2"",     verbose=True,     callback_manager=callb"

Most generative model architectures are supported, such as Falcon, Llama 2, GPT2, T5 and many more.  ##Installation[​](#installation) To get started with Iris Takeoff, all you need is to have docker and python installed on your local system. If you wish to use the server with gpu support, then you will need to install docker with cuda support.  For Mac and Windows users, make sure you have the docker daemon running! You can check this by running docker ps in your terminal. To start the daemon, open the docker desktop app.  Run the following command to install the Iris CLI that will enable you to run the takeoff server:  pip install titan-iris  ##Choose a Model[​](#choose-a-model) Takeoff supports many of the most powerful generative text models, such as Falcon, MPT, and Llama. See the [supported models](https://docs.titanml.co/docs/titan-takeoff/supported-models) for more information. For information about using your own models, see the [custom models](https://docs.titanml.co/docs/titan-takeoff/Advanced/custom-models).  Going forward in this demo we will be using the falcon 7B instruct model. This is a good open-source model that is trained to follow instructions, and is small enough to easily inference even on CPUs.  ##Taking off[​](#taking-off) Models are referred to by their model id on HuggingFace. Takeoff uses port 8000 by default, but can be configured to use another port. There is also support to use a Nvidia GPU by specifying cuda for the device flag.  To start the takeoff server, run:  iris takeoff --model tiiuae/falcon-7b-instruct --device cpu iris takeoff --model tiiuae/falcon-7b-instruct --device cuda # Nvidia GPU required iris takeoff --model tiiuae/falcon-7b-instruct --device cpu --port 5000 # run on port 5000 (default: 8000)  You will then be directed to a login page, where you will need to create an account to proceed. After logging in, run the command onscreen to check whether the server is ready. When it is ready, you can start using the Takeoff integration.  To shutdown the server, run the following command. You will be presented with options on which Takeoff server to shut down, in case you have multiple running servers.  iris takeoff --shutdown # shutdown the server  ##Inferencing your model[​](#inferencing-your-model) To access your LLM, use the TitanTakeoff LLM wrapper:  from langchain.llms import TitanTakeoff  llm = TitanTakeoff(     base_url=""http://localhost:8000"", generate_max_length=128, temperature=1.0 )  prompt = ""What is the largest planet in the solar system?""  llm(prompt)  No parameters are needed by default, but a baseURL that points to your desired URL where Takeoff is running can be specified and [generation parameters](https://docs.titanml.co/docs/titan-takeoff/Advanced/generation-parameters) can be supplied.  ###Streaming[​](#streaming) Streaming is also supported via the streaming flag:  from langchain.callbacks.manager import CallbackManager from langchain.callbacks.streaming_stdout import StreamingStdOutCallbackHandler  llm = TitanTakeoff(     callback_manager=CallbackManager([StreamingStdOutCallbackHandler()]), streaming=True )  prompt = ""What is the capital of France?""  llm(prompt)  ###Integration with LLMChain[​](#integration-with-llmchain) from langchain.chains import LLMChain from langchain.prompts import PromptTemplate  llm = TitanTakeoff()  template = ""What is the capital of {country}""  prompt = PromptTemplate(template=template, input_variables=[""country""])  llm_chain = LLMChain(llm=llm, prompt=prompt)  generated = llm_chain.run(country=""Belgium"") print(generated)    "

This notebook goes over how to use DynamoDB to store chat message history.  First make sure you have correctly configured the [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html). Then make sure you have installed boto3.  pip install boto3  Next, create the DynamoDB Table where we will be storing messages:  import boto3  # Get the service resource. dynamodb = boto3.resource(""dynamodb"")  # Create the DynamoDB table. table = dynamodb.create_table(     TableName=""SessionTable"",     KeySchema=[{""AttributeName"": ""SessionId"", ""KeyType"": ""HASH""}],     AttributeDefinitions=[{""AttributeName"": ""SessionId"", ""AttributeType"": ""S""}],     BillingMode=""PAY_PER_REQUEST"", )  # Wait until the table exists. table.meta.client.get_waiter(""table_exists"").wait(TableName=""SessionTable"")  # Print out some data about the table. print(table.item_count)      0  ##DynamoDBChatMessageHistory[​](#dynamodbchatmessagehistory) from langchain.memory.chat_message_histories import DynamoDBChatMessageHistory  history = DynamoDBChatMessageHistory(table_name=""SessionTable"", session_id=""0"")  history.add_user_message(""hi!"")  history.add_ai_message(""whats up?"")  history.messages      [HumanMessage(content='hi!', additional_kwargs={}, example=False),      AIMessage(content='whats up?', additional_kwargs={}, example=False),      HumanMessage(content='hi!', additional_kwargs={}, example=False),      AIMessage(content='whats up?', additional_kwargs={}, example=False)]  ##DynamoDBChatMessageHistory with Custom Endpoint URL[​](#dynamodbchatmessagehistory-with-custom-endpoint-url) Sometimes it is useful to specify the URL to the AWS endpoint to connect to.

It is particularly useful in handling structured data, i.e., data incorporating relations among entities and variables.  [SQLAlchemy](https://github.com/sqlalchemy/sqlalchemy) is an open-source SQL toolkit and object-relational mapper (ORM) for the Python programming language released under the MIT License.  This notebook goes over a SQLChatMessageHistory class that allows to store chat history in any database supported by SQLAlchemy.  Please note that to use it with databases other than SQLite, you will need to install the corresponding database driver.  ##Basic Usage[​](#basic-usage) To use the storage you need to provide only 2 things:  - Session Id - a unique identifier of the session, like user name, email, chat id etc. - Connection string - a string that specifies the database connection. It will be passed to SQLAlchemy create_engine function. - Install SQLAlchemy python package. pip install SQLAlchemy  from langchain.memory.chat_message_histories import SQLChatMessageHistory  chat_message_history = SQLChatMessageHistory(     session_id=""test_session"", connection_string=""sqlite:///sqlite.db"" )  chat_message_history.add_user_message(""Hello"") chat_message_history.add_ai_message(""Hi"")  chat_message_history.messages      [HumanMessage(content='Hello', additional_kwargs={}, example=False),      AIMessage(content='Hi', additional_kwargs={}, example=False)]  ##Custom Storage Format[​](#custom-storage-format) By default, only the session id and message dictionary are stored in the table.  However, sometimes you might want to store some additional information, like message date, author, language etc.  To do that, you can create a custom message converter, by implementing BaseMessageConverter interface.  from datetime import datetime from typing import Any  from langchain.memory.chat_message_histories.sql import BaseMessageConverter from langchain.schema import AIMessage, BaseMessage, HumanMessage, SystemMessage from sqlalchemy import Column, DateTime, Integer, Text from sqlalchemy.orm import declarative_base  Base = declarative_base()   class CustomMessage(Base):     __tablename__ = ""custom_message_store""      id = Column(Integer, primary_key=True)     session_id = Column(Text)     type = Column(Text)     content = Column(Text)     created_at = Column(DateTime)     author_email = Column(Text)   class CustomMessageConverter(BaseMessageConverter):     def __init__(self, author_email: str):         self.author_email = author_email      def from_sql_model(self, sql_message: Any) -> BaseMessage:         if sql_message.type == ""human"":             return HumanMessage(                 content=sql_message.content,             )         elif sql_message.type == ""ai"":             return AIMessage(                 content=sql_message.content,             )         elif sql_message.type == ""system"":             return SystemMessage(                 content=sql_message.content,             )         else:             raise ValueError(f""Unknown message type: {sql_message.type}"")      def to_sql_model(self, message: BaseMessage, session_id: str) -> Any:         now = datetime.now()         return CustomMessage(             session_id=session_id,             type=message.type,             content=message.content,             created_at=now,             author_email=self.author_email,         )      def get_sql_model_class(self) -> Any:         return CustomMessage   chat_message_history = SQLChatMessageHistory(     session_id=""test_session"",     connection_string=""sqlite:///sqlite.db"",     custom_message_converter=CustomMessageConverter(author_email=""test@example.com""), )  chat_message_history.add_user_message(""Hello"") chat_message_history.add_ai_message(""Hi"")  chat_message_history.messages      [HumanMessage(content='Hello', additional_kwargs={}, example=False),      AIMessage(content='Hi', additional_kwargs={}, example=False)]  You also might want to change the name of session_id column. In this case you'll need to specify session_id_field_name parameter.  "

Xata | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/memory/xata_chat_message_history,langchain_docs,"Main:  On this page #Xata [Xata](https://xata.io) is a serverless data platform, based on PostgreSQL and Elasticsearch. It provides a Python SDK for interacting with your database, and a UI for managing your data. With the XataChatMessageHistory class, you can use Xata databases for longer-term persistence of chat sessions.  This notebook covers:  - A simple example showing what XataChatMessageHistory does. - A more complex example using a REACT agent that answer questions based on a knowledge based or documentation (stored in Xata as a vector store) and also having a long-term searchable history of its past messages (stored in Xata as a memory store) ##Setup[​](#setup) ###Create a database[​](#create-a-database) In the [Xata UI](https://app.xata.io) create a new database. You can name it whatever you want, in this notepad we'll use langchain. The Langchain integration can auto-create the table used for storying the memory, and this is what we'll use in this example. If you want to pre-create the table, ensure it has the right schema and set create_table to False when creating the class. Pre-creating the table saves one round-trip to the database during each session initialization.  Let's first install our dependencies:  pip install xata openai langchain  Next, we need to get the environment variables for Xata. You can create a new API key by visiting your [account settings](https://app.xata.io/settings). To find the database URL, go to the Settings page of the database that you have created. The database URL should look something like this: https://demo-uni3q8.eu-west-1.xata.sh/db/langchain.  import getpass  api_key = getpass.getpass(""Xata API key: "") db_url = input(""Xata database URL (copy it from your DB settings):"")  ##Create a simple memory store[​](#create-a-simple-memory-store) To test the memory store functionality in isolation, let's use the following code snippet:  from langchain.memory import XataChatMessageHistory  history = XataChatMessageHistory(     session_id=""session-1"", api_key=api_key, db_url=db_url, table_name=""memory"" )  history.add_user_message(""hi!"")  history.add_ai_message(""whats up?"")  The above code creates a session with the ID session-1 and stores two messages in it. After running the above, if you visit the Xata UI, you should see a table named memory and the two messages added to it.  You can retrieve the message history for a particular session with the following code:  history.messages  ##Conversational Q&A chain on your data with memory[​](#conversational-qa-chain-on-your-data-with-memory) Let's now see a more complex example in which we combine OpenAI, the Xata Vector Store integration, and the Xata memory store integration to create a Q&A chat bot on your data, with follow-up questions and history.  We're going to need to access the OpenAI API, so let's configure the API key:  import os  os.environ[""OPENAI_API_KEY""] = getpass.getpass(""OpenAI API Key:"")  To store the documents that the chatbot will search for answers, add a table named docs to your langchain database using the Xata UI, and add the following columns:  - content of type ""Text"". This is used to store the Document.pageContent values. - embedding of type ""Vector"". Use the dimension used by the model you plan to use. In this notebook we use OpenAI embeddings, which have 1536 dimensions. Let's create the vector store and add some sample docs to it:  from langchain.embeddings.openai import OpenAIEmbeddings from langchain.vectorstores.xata import XataVectorStore  embeddings = OpenAIEmbeddings()  texts = [     ""Xata is a Serverless Data platform based on PostgreSQL"",     ""Xata offers a built-in vector type that can be used to store and query vectors"",     ""Xata includes similarity search"", ]  vector_store = XataVectorStore.from_texts(     texts, embeddings, api_key=api_key, db_url=db_url, table_name=""docs"" )  After running the above command, if you go to the Xata UI, you should see the documents loaded together with their embeddings in the docs table.  Let's now create a ConversationBufferMemory to store the chat messages from both the user and the AI.  from uuid import uuid4  from langchain.memory import ConversationBufferMemory  chat_memory = XataChatMessageHistory(     session_id=str(uuid4()),  # needs to be unique per user session     api_key=api_key,     db_url=db_url,     table_name=""memory"", ) memory = ConversationBufferMemory(     memory_key=""chat_history"", chat_memory=chat_memory, return_messages=True )  Now it's time to create an Agent to use both the vector store and the chat memory together.  from langchain.agents import AgentType, initialize_agent from langchain.agents.agent_toolkits import create_retriever_tool from langchain.chat_models import ChatOpenAI  tool = create_retriever_tool(     vector_store.as_retriever(),     ""search_docs"",     ""Searches and returns documents from the Xata manual. Useful when you need to answer questions about Xata."", ) tools = [tool]  llm = ChatOpenAI(temperature=0)  agent = initialize_agent(     tools,     llm,     agent=AgentType.CHAT_CONVERSATIONAL_REACT_DESCRIPTION,     verbose=True,     memory=memory, )  To test, let's tell the agent our name:  agent.run(input=""My name is bob"")  Now, let's now ask the agent some questions about Xata:  agent.run(input=""What is xata?"")  Notice that it answers based on the data stored in the document store. And now, let's ask a follow up question:  agent.run(input=""Does it support similarity search?"")  And now let's test its memory:  agent.run(input=""Did I tell you my name? What is it?"")    "

Anthropic | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/platforms/anthropic,langchain_docs,"Main:  On this page #Anthropic All functionality related to Anthropic models.  [Anthropic](https://www.anthropic.com/) is an AI safety and research company, and is the creator of Claude. This page covers all integrations between Anthropic models and LangChain.  ##Prompting Overview[​](#prompting-overview) Claude is chat-based model, meaning it is trained on conversation data. However, it is a text based API, meaning it takes in single string. It expects this string to be in a particular format. This means that it is up the user to ensure that is the case. LangChain provides several utilities and helper functions to make sure prompts that you write - whether formatted as a string or as a list of messages - end up formatted correctly.  Specifically, Claude is trained to fill in text for the Assistant role as part of an ongoing dialogue between a human user (Human:) and an AI assistant (Assistant:). Prompts sent via the API must contain \n\nHuman: and \n\nAssistant: as the signals of who's speaking. The final turn must always be \n\nAssistant: - the input string cannot have \n\nHuman: as the final role.  Because Claude is chat-based but accepts a string as input, it can be treated as either a LangChain ChatModel or LLM. This means there are two wrappers in LangChain - ChatAnthropic and Anthropic. It is generally recommended to use the ChatAnthropic wrapper, and format your prompts as ChatMessages (we will show examples of this below). This is because it keeps your prompt in a general format that you can easily then also use with other models (should you want to). However, if you want more fine-grained control over the prompt, you can use the Anthropic wrapper - we will show and example of this as well. The Anthropic wrapper however is deprecated, as all functionality can be achieved in a more generic way using ChatAnthropic.  ##Prompting Best Practices[​](#prompting-best-practices) Anthropic models have several prompting best practices compared to OpenAI models.  No System Messages  Anthropic models are not trained on the concept of a ""system message"". We have worked with the Anthropic team to handle them somewhat appropriately (a Human message with an admin tag) but this is largely a hack and it is recommended that you do not use system messages.  AI Messages Can Continue  A completion from Claude is a continuation of the last text in the string which allows you further control over Claude's output. For example, putting words in Claude's mouth in a prompt like this:  \n\nHuman: Tell me a joke about bears\n\nAssistant: What do you call a bear with no teeth?  This will return a completion like this A gummy bear! instead of a whole new assistant message with a different random bear joke.  ##ChatAnthropic[​](#chatanthropic) ChatAnthropic is a subclass of LangChain's ChatModel, meaning it works best with ChatPromptTemplate. You can import this wrapper with the following code:  from langchain.chat_models import ChatAnthropic model = ChatAnthropic()  When working with ChatModels, it is preferred that you design your prompts as ChatPromptTemplates. Here is an example below of doing that:  from langchain.prompts import ChatPromptTemplate  prompt = ChatPromptTemplate.from_messages([     (""system"", ""You are a helpful chatbot""),     (""human"", ""Tell me a joke about {topic}""), ])  You can then use this in a chain as follows:  chain = prompt | model chain.invoke({""topic"": ""bears""})  How is the prompt actually being formatted under the hood? We can see that by running the following code  prompt_value = prompt.format_prompt(topic=""bears"") model.convert_prompt(prompt_value)  This produces the following formatted string:  '\n\nYou are a helpful chatbot\n\nHuman: Tell me a joke about bears\n\nAssistant:'  We can see that under the hood LangChain is not appending any prefix/suffix to SystemMessage's. This is because Anthropic has no concept of SystemMessage. Anthropic requires all prompts to end with assistant messages. This means if the last message is not an assistant message, the suffix Assistant: will automatically be inserted.  If you decide instead to use a normal PromptTemplate (one that just works on a single string) let's take a look at what happens:  from langchain.prompts import PromptTemplate  prompt = PromptTemplate.from_template(""Tell me a joke about {topic}"") prompt_value = prompt.format_prompt(topic=""bears"") model.convert_prompt(prompt_value)  This produces the following formatted string:  '\n\nHuman: Tell me a joke about bears\n\nAssistant:'  We can see that it automatically adds the Human and Assistant tags. What is happening under the hood? First: the string gets converted to a single human message. This happens generically (because we are using a subclass of ChatModel). Then, similarly to the above example, an empty Assistant message is getting appended. This is Anthropic specific.  ##[Deprecated] Anthropic[​](#deprecated-anthropic) This Anthropic wrapper is subclassed from LLM. We can import it with:  from langchain.llms import Anthropic model = Anthropic()  This model class is designed to work with normal PromptTemplates. An example of that is below:  prompt = PromptTemplate.from_template(""Tell me a joke about {topic}"") chain = prompt | model chain.invoke({""topic"": ""bears""})  Let's see what is going on with the prompt templating under the hood!  prompt_value = prompt.format_prompt(topic=""bears"") model.convert_prompt(prompt_value)  This outputs the following  '\n\nHuman: Tell me a joke about bears\n\nAssistant: Sure, here you go:\n'  Notice that it adds the Human tag at the start of the string, and then finishes it with \n\nAssistant: Sure, here you go:. The extra Sure, here you go was added on purpose by the Anthropic team.  What happens if we have those symbols in the prompt directly?  prompt = PromptTemplate.from_template(""Human: Tell me a joke about {topic}"") prompt_value = prompt.format_prompt(topic=""bears"") model.convert_prompt(prompt_value)  This outputs:  '\n\nHuman: Tell me a joke"

A callback handler, also known as a callback function or callback method, is a piece of code that is executed in response to a specific event or condition. It is commonly used in programming languages that support event-driven or asynchronous programming paradigms.          The purpose of a callback handler is to provide a way for developers to define custom behavior that should be executed when a certain event occurs. Instead of waiting for a result or blocking the execution, the program registers a callback function and continues with other tasks. When the event is triggered, the callback function is invoked, allowing the program to respond accordingly.          Callback handlers are commonly used in various scenarios, such as handling user input, responding to network requests, processing asynchronous operations, and implementing event-driven architectures. They provide a flexible and modular way to handle events and decouple different components of a system.     >>> input >>>     >>>: What do I need to do to get the full benefits of this     To get the full benefits of using a callback handler, you should consider the following:          1. Understand the event or condition: Identify the specific event or condition that you want to respond to with a callback handler. This could be user input, network requests, or any other asynchronous operation.          2. Define the callback function: Create a function that will be executed when the event or condition occurs. This function should contain the desired behavior or actions you want to take in response to the event.          3. Register the callback function: Depending on the programming language or framework you are using, you may need to register or attach the callback function to the appropriate event or condition. This ensures that the callback function is invoked when the event occurs.          4. Handle the callback: Implement the necessary logic within the callback function to handle the event or condition. This could involve updating the user interface, processing data, making further requests, or triggering other actions.          5. Consider error handling: It's important to handle any potential errors or exceptions that may occur within the callback function. This ensures that your program can gracefully handle unexpected situations and prevent crashes or undesired behavior.          6. Maintain code readability and modularity: As your codebase grows, it's crucial to keep your callback handlers organized and maintainable. Consider using design patterns or architectural principles to structure your code in a modular and scalable way.          By following these steps, you can leverage the benefits of callback handlers, such as asynchronous and event-driven programming, improved responsiveness, and modular code design.     >>> input >>>     >>>: q    "

Clarifai provides an AI platform with the full AI lifecycle for data exploration, data labeling, model training, evaluation and inference around images, video, text and audio data. In the LangChain ecosystem, as far as we're aware, Clarifai is the only provider that supports LLMs, embeddings and a vector store in one production scale platform, making it an excellent choice to operationalize your LangChain implementations.  ##Installation and Setup[​](#installation-and-setup) - Install the Python SDK: pip install clarifai  [Sign-up](https://clarifai.com/signup) for a Clarifai account, then get a personal access token to access the Clarifai API from your [security settings](https://clarifai.com/settings/security) and set it as an environment variable (CLARIFAI_PAT).  ##Models[​](#models) Clarifai provides 1,000s of AI models for many different use cases. You can [explore them here](https://clarifai.com/explore) to find the one most suited for your use case. These models include those created by other providers such as OpenAI, Anthropic, Cohere, AI21, etc. as well as state of the art from open source such as Falcon, InstructorXL, etc. so that you build the best in AI into your products. You'll find these organized by the creator's user_id and into projects we call applications denoted by their app_id. Those IDs will be needed in additional to the model_id and optionally the version_id, so make note of all these IDs once you found the best model for your use case!  Also note that given there are many models for images, video, text and audio understanding, you can build some interested AI agents that utilize the variety of AI models as experts to understand those data types.  ###LLMs[​](#llms) To find the selection of LLMs in the Clarifai platform you can select the text to text model type [here](https://clarifai.com/explore/models?filterData=%5B%7B%22field%22%3A%22model_type_id%22%2C%22value%22%3A%5B%22text-to-text%22%5D%7D%5D&page=1&perPage=24).  from langchain.llms import Clarifai llm = Clarifai(pat=CLARIFAI_PAT, user_id=USER_ID, app_id=APP_ID, model_id=MODEL_ID)  For more details, the docs on the Clarifai LLM wrapper provide a [detailed walkthrough](/docs/integrations/llms/clarifai).  ###Text Embedding Models[​](#text-embedding-models) To find the selection of text embeddings models in the Clarifai platform you can select the text to embedding model type [here](https://clarifai.com/explore/models?page=1&perPage=24&filterData=%5B%7B%22field%22%3A%22model_type_id%22%2C%22value%22%3A%5B%22text-embedder%22%5D%7D%5D).  There is a Clarifai Embedding model in LangChain, which you can access with:  from langchain.embeddings import ClarifaiEmbeddings embeddings = ClarifaiEmbeddings(pat=CLARIFAI_PAT, user_id=USER_ID, app_id=APP_ID, model_id=MODEL_ID)  For more details, the docs on the Clarifai Embeddings wrapper provide a [detailed walkthrough](/docs/integrations/text_embedding/clarifai).  ##Vectorstore[​](#vectorstore) Clarifai's vector DB was launched in 2016 and has been optimized to support live search queries. With workflows in the Clarifai platform, you data is automatically indexed by am embedding model and optionally other models as well to index that information in the DB for search. You can query the DB not only via the vectors but also filter by metadata matches, other AI predicted concepts, and even do geo-coordinate search. Simply create an application, select the appropriate base workflow for your type of data, and upload it (through the API as [documented here](https://docs.clarifai.com/api-guide/data/create-get-update-delete) or the UIs at clarifai.com).  You can also add data directly from LangChain as well, and the auto-indexing will take place for you. You'll notice this is a little different than other vectorstores where you need to provide an embedding model in their constructor and have LangChain coordinate getting the embeddings from text and writing those to the index. Not only is it more convenient, but it's much more scalable to use Clarifai's distributed cloud to do all the index in the background.  from langchain.vectorstores import Clarifai clarifai_vector_db = Clarifai.from_texts(user_id=USER_ID, app_id=APP_ID, texts=texts, pat=CLARIFAI_PAT, number_of_docs=NUMBER_OF_DOCS, metadatas = metadatas)  For more details, the docs on the Clarifai vector store provide a [detailed walkthrough](/docs/integrations/vectorstores/clarifai).

ClearML | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/providers/clearml_tracking,langchain_docs,"m.988bd727b0e94a29a3ac0ee526813545/models/simple_sequential  At this point you can already go to https://app.clear.ml and take a look at the resulting ClearML Task that was created.  Among others, you should see that this notebook is saved along with any git information. The model JSON that contains the used parameters is saved as an artifact, there are also console logs and under the plots section, you'll find tables that represent the flow of the chain.  Finally, if you enabled visualizations, these are stored as HTML files under debug samples.  Scenario 2: Creating an agent with tools​ To show a more advanced workflow, let's create an agent with access to tools. The way ClearML tracks the results is not different though, only the table will look slightly different as there are other types of actions taken when compared to the earlier, simpler example.  You can now also see the use of the finish=True keyword, which will fully close the ClearML Task, instead of just resetting the parameters and prompts for a new conversation.  from langchain.agents import AgentType, initialize_agent, load_tools  # SCENARIO 2 - Agent with Tools tools = load_tools([""serpapi"", ""llm-math""], llm=llm, callbacks=callbacks) agent = initialize_agent(     tools,     llm,     agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,     callbacks=callbacks, ) agent.run(""Who is the wife of the person who sang summer of 69?"") clearml_callback.flush_tracker(     langchain_asset=agent, name=""Agent with Tools"", finish=True )                > Entering new AgentExecutor chain...     {'action': 'on_chain_start', 'name': 'AgentExecutor', 'step': 1, 'starts': 1, 'ends': 0, 'errors': 0, 'text_ctr': 0, 'chain_starts': 1, 'chain_ends': 0, 'llm_starts': 0, 'llm_ends': 0, 'llm_streams': 0, 'tool_starts': 0, 'tool_ends': 0, 'agent_ends': 0, 'input': 'Who is the wife of the person who sang summer of 69?'}     {'action': 'on_llm_start', 'name': 'OpenAI', 'step': 2, 'starts': 2, 'ends': 0, 'errors': 0, 'text_ctr': 0, 'chain_starts': 1, 'chain_ends': 0, 'llm_starts': 1, 'llm_ends': 0, 'llm_streams': 0, 'tool_starts': 0, 'tool_ends': 0, 'agent_ends': 0, 'prompts': 'Answer the following questions as best you can.

Flyte | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/providers/flyte,langchain_docs,"Main:  On this page #Flyte [Flyte](https://github.com/flyteorg/flyte) is an open-source orchestrator that facilitates building production-grade data and ML pipelines. It is built for scalability and reproducibility, leveraging Kubernetes as its underlying platform.  The purpose of this notebook is to demonstrate the integration of a FlyteCallback into your Flyte task, enabling you to effectively monitor and track your LangChain experiments.  ##Installation & Setup[​](#installation--setup) - Install the Flytekit library by running the command pip install flytekit. - Install the Flytekit-Envd plugin by running the command pip install flytekitplugins-envd. - Install LangChain by running the command pip install langchain. - Install [Docker](https://docs.docker.com/engine/install/) on your system. ##Flyte Tasks[​](#flyte-tasks) A Flyte [task](https://docs.flyte.org/projects/cookbook/en/latest/auto/core/flyte_basics/task.html) serves as the foundational building block of Flyte. To execute LangChain experiments, you need to write Flyte tasks that define the specific steps and operations involved.  NOTE: The [getting started guide](https://docs.flyte.org/projects/cookbook/en/latest/index.html) offers detailed, step-by-step instructions on installing Flyte locally and running your initial Flyte pipeline.  First, import the necessary dependencies to support your LangChain experiments.  import os  from flytekit import ImageSpec, task from langchain.agents import AgentType, initialize_agent, load_tools from langchain.callbacks import FlyteCallbackHandler from langchain.chains import LLMChain from langchain.chat_models import ChatOpenAI from langchain.prompts import PromptTemplate from langchain.schema import HumanMessage  Set up the necessary environment variables to utilize the OpenAI API and Serp API:  # Set OpenAI API key os.environ[""OPENAI_API_KEY""] = ""<your_openai_api_key>""  # Set Serp API key os.environ[""SERPAPI_API_KEY""] = ""<your_serp_api_key>""  Replace <your_openai_api_key> and <your_serp_api_key> with your respective API keys obtained from OpenAI and Serp API.  To guarantee reproducibility of your pipelines, Flyte tasks are containerized. Each Flyte task must be associated with an image, which can either be shared across the entire Flyte [workflow](https://docs.flyte.org/projects/cookbook/en/latest/auto/core/flyte_basics/basic_workflow.html) or provided separately for each task.  To streamline the process of supplying the required dependencies for each Flyte task, you can initialize an [ImageSpec](https://docs.flyte.org/projects/cookbook/en/latest/auto/core/image_spec/image_spec.html) object. This approach automatically triggers a Docker build, alleviating the need for users to manually create a Docker image.  custom_image = ImageSpec(     name=""langchain-flyte"",     packages=[         ""langchain"",         ""openai"",         ""spacy"",         ""https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-3.5.0/en_core_web_sm-3.5.0.tar.gz"",         ""textstat"",         ""google-search-results"",     ],     registry=""<your-registry>"", )  You have the flexibility to push the Docker image to a registry of your preference. [Docker Hub](https://hub.docker.com/) or [GitHub Container Registry (GHCR)](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry) is a convenient option to begin with.  Once you have selected a registry, you can proceed to create Flyte tasks that log the LangChain metrics to Flyte Deck.  The following examples demonstrate tasks related to OpenAI LLM, chains and agent with tools:  ###LLM[​](#llm) @task(disable_deck=False, container_image=custom_image) def langchain_llm() -> str:     llm = ChatOpenAI(         model_name=""gpt-3.5-turbo"",         temperature=0.2,         callbacks=[FlyteCallbackHandler()],     )     return llm([HumanMessage(content=""Tell me a joke"")]).content  ###Chain[​](#chain) @task(disable_deck=False, container_image=custom_image) def langchain_chain() -> list[dict[str, str]]:     template = """"""You are a playwright.

Could you calculate her current age and raise it to the power of 0.43?""     )  These tasks serve as a starting point for running your LangChain experiments within Flyte.  ##Execute the Flyte Tasks on Kubernetes[​](#execute-the-flyte-tasks-on-kubernetes) To execute the Flyte tasks on the configured Flyte backend, use the following command:  pyflyte run --image <your-image> langchain_flyte.py langchain_llm  This command will initiate the execution of the langchain_llm task on the Flyte backend. You can trigger the remaining two tasks in a similar manner.  The metrics will be displayed on the Flyte UI as follows:    "

Marqo | 🦜️🔗 Langchain,https://python.langchain.com/docs/integrations/providers/marqo,langchain_docs,"Main:  On this page #Marqo This page covers how to use the Marqo ecosystem within LangChain.  ###What is Marqo?[​](#what-is-marqo) Marqo is a tensor search engine that uses embeddings stored in in-memory HNSW indexes to achieve cutting edge search speeds. Marqo can scale to hundred-million document indexes with horizontal index sharding and allows for async and non-blocking data upload and search. Marqo uses the latest machine learning models from PyTorch, Huggingface, OpenAI and more. You can start with a pre-configured model or bring your own. The built in ONNX support and conversion allows for faster inference and higher throughput on both CPU and GPU.  Because Marqo include its own inference your documents can have a mix of text and images, you can bring Marqo indexes with data from your other systems into the langchain ecosystem without having to worry about your embeddings being compatible.  Deployment of Marqo is flexible, you can get started yourself with our docker image or [contact us about our managed cloud offering!](https://www.marqo.ai/pricing)  To run Marqo locally with our docker image, [see our getting started.](https://docs.marqo.ai/latest/)  ##Installation and Setup[​](#installation-and-setup) - Install the Python SDK with pip install marqo ##Wrappers[​](#wrappers) ###VectorStore[​](#vectorstore) There exists a wrapper around Marqo indexes, allowing you to use them within the vectorstore framework. Marqo lets you select from a range of models for generating embeddings and exposes some preprocessing configurations.  The Marqo vectorstore can also work with existing multimodel indexes where your documents have a mix of images and text, for more information refer to [our documentation](https://docs.marqo.ai/latest/#multi-modal-and-cross-modal-search). Note that instaniating the Marqo vectorstore with an existing multimodal index will disable the ability to add any new documents to it via the langchain vectorstore add_texts method.
