Prediction Guard
Contents
Installation and Setup
LLM Wrapper
Example usage
Prediction Guard#
This page covers how to use the Prediction Guard ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific Prediction Guard wrappers.
Installation and Setup#
Install the Python SDK with pip install predictionguard
Get an Prediction Guard access token (as described here) and set it as an environment variable (PREDICTIONGUARD_TOKEN)
LLM Wrapper#
There exists a Prediction Guard LLM wrapper, which you can access with
from langchain.llms import PredictionGuard
You can provide the name of your Prediction Guard “proxy” as an argument when initializing the LLM:
pgllm = PredictionGuard(name="your-text-gen-proxy")
Alternatively, you can use Prediction Guard’s default proxy for SOTA LLMs:
pgllm = PredictionGuard(name="default-text-gen")
You can also provide your access token directly as an argument:
pgllm = PredictionGuard(name="default-text-gen", token="<your access token>")
Example usage#
Basic usage of the LLM wrapper:
from langchain.llms import PredictionGuard
pgllm = PredictionGuard(name="default-text-gen")
pgllm("Tell me a joke")
Basic LLM Chaining with the Prediction Guard wrapper:
from langchain import PromptTemplate, LLMChain
from langchain.llms import PredictionGuard
template = """Question: {question}
Answer: Let's think step by step.""" | /content/https://python.langchain.com/en/latest/ecosystem/predictionguard.html |
0dc0f0d4c82c-1 | Answer: Let's think step by step."""
prompt = PromptTemplate(template=template, input_variables=["question"])
llm_chain = LLMChain(prompt=prompt, llm=PredictionGuard(name="default-text-gen"), verbose=True)
question = "What NFL team won the Super Bowl in the year Justin Beiber was born?"
llm_chain.predict(question=question)

PromptLayer#
This page covers how to use PromptLayer within LangChain.
It is broken into two parts: installation and setup, and then references to specific PromptLayer wrappers.
Installation and Setup#
If you want to work with PromptLayer:
Install the promptlayer python library pip install promptlayer
Create a PromptLayer account
Create an api token and set it as an environment variable (PROMPTLAYER_API_KEY)
Wrappers#
LLM#
There exists an PromptLayer OpenAI LLM wrapper, which you can access with
from langchain.llms import PromptLayerOpenAI
To tag your requests, use the argument pl_tags when instanializing the LLM
from langchain.llms import PromptLayerOpenAI
llm = PromptLayerOpenAI(pl_tags=["langchain-requests", "chatbot"])
To get the PromptLayer request id, use the argument return_pl_id when instanializing the LLM
from langchain.llms import PromptLayerOpenAI
llm = PromptLayerOpenAI(return_pl_id=True)
This will add the PromptLayer request ID in the generation_info field of the Generation returned when using .generate or .agenerate
For example:
llm_results = llm.generate(["hello world"])
for res in llm_results.generations:
print("pl request id: ", res[0].generation_info["pl_request_id"]) | /content/https://python.langchain.com/en/latest/ecosystem/promptlayer.html |
3bb7134f1e4a-1 | You can use the PromptLayer request ID to add a prompt, score, or other metadata to your request. Read more about it here.
This LLM is identical to the OpenAI LLM, except that
all your requests will be logged to your PromptLayer account
you can add pl_tags when instantializing to tag your requests on PromptLayer
you can add return_pl_id when instantializing to return a PromptLayer request id to use while tracking requests.
PromptLayer also provides native wrappers for PromptLayerChatOpenAI and PromptLayerOpenAIChat

Installation and Setup
Wrappers
Data Loaders
Unstructured#
This page covers how to use the unstructured
ecosystem within LangChain. The unstructured package from
Unstructured.IO extracts clean text from raw source documents like
PDFs and Word documents.
This page is broken into two parts: installation and setup, and then references to specific
unstructured wrappers.
Installation and Setup#
Install the Python SDK with pip install "unstructured[local-inference]"
Install the following system dependencies if they are not already available on your system.
Depending on what document types you’re parsing, you may not need all of these.
libmagic-dev (filetype detection)
poppler-utils (images and PDFs)
tesseract-ocr(images and PDFs)
libreoffice (MS Office docs)
pandoc (EPUBs)
If you are parsing PDFs using the "hi_res" strategy, run the following to install the detectron2 model, which
unstructured uses for layout detection:
pip install "detectron2@git+https://github.com/facebookresearch/detectron2.git@e2ce8dc#egg=detectron2"
If detectron2 is not installed, unstructured will fallback to processing PDFs
using the "fast" strategy, which uses pdfminer directly and doesn’t require
detectron2.
Wrappers#
Data Loaders#
The primary unstructured wrappers within langchain are data loaders. The following
shows how to use the most basic unstructured data loader. There are other file-specific
data loaders available in the langchain.document_loaders module. | /content/https://python.langchain.com/en/latest/ecosystem/unstructured.html |
dc2bd8045c2d-1 | data loaders available in the langchain.document_loaders module.
from langchain.document_loaders import UnstructuredFileLoader
loader = UnstructuredFileLoader("state_of_the_union.txt")
loader.load()
If you instantiate the loader with UnstructuredFileLoader(mode="elements"), the loader
will track additional metadata like the page number and text type (i.e. title, narrative text)
when that information is available.

Aim
Aim#
Aim makes it super easy to visualize and debug LangChain executions. Aim tracks inputs and outputs of LLMs and tools, as well as actions of agents.
With Aim, you can easily debug and examine an individual execution:
Additionally, you have the option to compare multiple executions side by side:
Aim is fully open source, learn more about Aim on GitHub.
Let’s move forward and see how to enable and configure Aim callback.
Tracking LangChain Executions with AimIn this notebook we will explore three usage scenarios. To start off, we will install the necessary packages and import certain modules. Subsequently, we will configure two environment variables that can be established either within the Python script or through the terminal.
!pip install aim
!pip install langchain
!pip install openai
!pip install google-search-results
import os
from datetime import datetime
from langchain.llms import OpenAI
from langchain.callbacks.base import CallbackManager
from langchain.callbacks import AimCallbackHandler, StdOutCallbackHandler
Our examples use a GPT model as the LLM, and OpenAI offers an API for this purpose. You can obtain the key from the following link: https://platform.openai.com/account/api-keys .
We will use the SerpApi to retrieve search results from Google. To acquire the SerpApi key, please go to https://serpapi.com/manage-api-key .
os.environ["OPENAI_API_KEY"] = "..." | /content/https://python.langchain.com/en/latest/ecosystem/aim_tracking.html |
2177238e8cb6-1 | os.environ["OPENAI_API_KEY"] = "..."
os.environ["SERPAPI_API_KEY"] = "..."
The event methods of AimCallbackHandler accept the LangChain module or agent as input and log at least the prompts and generated results, as well as the serialized version of the LangChain module, to the designated Aim run.
session_group = datetime.now().strftime("%m.%d.%Y_%H.%M.%S")
aim_callback = AimCallbackHandler(
repo=".",
experiment_name="scenario 1: OpenAI LLM",
)
manager = CallbackManager([StdOutCallbackHandler(), aim_callback])
llm = OpenAI(temperature=0, callback_manager=manager, verbose=True)
The flush_tracker function is used to record LangChain assets on Aim. By default, the session is reset rather than being terminated outright.
Scenario 1 In the first scenario, we will use OpenAI LLM.
# scenario 1 - LLM
llm_result = llm.generate(["Tell me a joke", "Tell me a poem"] * 3)
aim_callback.flush_tracker(
langchain_asset=llm,

Installation and Setup
Calling a model
Replicate#
This page covers how to run models on Replicate within LangChain.
Installation and Setup#
Create a Replicate account. Get your API key and set it as an environment variable (REPLICATE_API_TOKEN)
Install the Replicate python client with pip install replicate
Calling a model#
Find a model on the Replicate explore page, and then paste in the model name and version in this format: owner-name/model-name:version
For example, for this flan-t5 model, click on the API tab. The model name/version would be: daanelson/flan-t5:04e422a9b85baed86a4f24981d7f9953e20c5fd82f6103b74ebc431588e1cec8
Only the model param is required, but any other model parameters can also be passed in with the format input={model_param: value, ...}
For example, if we were running stable diffusion and wanted to change the image dimensions:
Replicate(model="stability-ai/stable-diffusion:db21e45d3f7023abc2a46ee38a23973f6dce16bb082a930b0c49861f96d1e5bf", input={'image_dimensions': '512x512'})
Note that only the first output of a model will be returned.
From here, we can initialize our model: | /content/https://python.langchain.com/en/latest/ecosystem/replicate.html |
87c3efff00f8-1 | From here, we can initialize our model:
llm = Replicate(model="daanelson/flan-t5:04e422a9b85baed86a4f24981d7f9953e20c5fd82f6103b74ebc431588e1cec8")
And run it:
prompt = """
Answer the following yes/no question by reasoning step by step.
Can a dog drive a car?
"""
llm(prompt)
We can call any Replicate model (not just LLMs) using this syntax. For example, we can call Stable Diffusion:
text2image = Replicate(model="stability-ai/stable-diffusion:db21e45d3f7023abc2a46ee38a23973f6dce16bb082a930b0c49861f96d1e5bf",
input={'image_dimensions'='512x512'}
image_output = text2image("A cat riding a motorcycle by Picasso")

SearxNG Search API#
This page covers how to use the SearxNG search API within LangChain.
It is broken into two parts: installation and setup, and then references to the specific SearxNG API wrapper.
Installation and Setup#
While it is possible to utilize the wrapper in conjunction with public searx
instances these instances frequently do not permit API
access (see note on output format below) and have limitations on the frequency
of requests. It is recommended to opt for a self-hosted instance instead.
Self Hosted Instance:#
See this page for installation instructions.
When you install SearxNG, the only active output format by default is the HTML format.
You need to activate the json format to use the API. This can be done by adding the following line to the settings.yml file:
search:
formats:
- html
- json
You can make sure that the API is working by issuing a curl request to the API endpoint:
curl -kLX GET --data-urlencode q='langchain' -d format=json http://localhost:8888
This should return a JSON object with the results.
Wrappers#
Utility#
To use the wrapper we need to pass the host of the SearxNG instance to the wrapper with:
1. the named parameter searx_host when creating the instance.
2. exporting the environment variable SEARXNG_HOST.
You can use the wrapper to get results from a SearxNG instance.
from langchain.utilities import SearxSearchWrapper | /content/https://python.langchain.com/en/latest/ecosystem/searx.html |
2a43d5342920-1 | from langchain.utilities import SearxSearchWrapper
s = SearxSearchWrapper(searx_host="http://localhost:8888")
s.run("what is a large language model?")
Tool#
You can also load this wrapper as a Tool (to use with an Agent).
You can do this with:
from langchain.agents import load_tools
tools = load_tools(["searx-search"],
searx_host="http://localhost:8888",
engines=["github"])
Note that we could optionally pass custom engines to use.
If you want to obtain results with metadata as json you can use:
tools = load_tools(["searx-search-results-json"],
searx_host="http://localhost:8888",
num_results=5)

This page covers how to use the OpenAI ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific OpenAI wrappers.
Installation and Setup#
Install the Python SDK with pip install openai
Get an OpenAI api key and set it as an environment variable (OPENAI_API_KEY)
If you want to use OpenAI’s tokenizer (only available for Python 3.9+), install it with pip install tiktoken
Wrappers#
LLM#
There exists an OpenAI LLM wrapper, which you can access with
from langchain.llms import OpenAI
If you are using a model hosted on Azure, you should use different wrapper for that:
from langchain.llms import AzureOpenAI
For a more detailed walkthrough of the Azure wrapper, see this notebook
Embeddings#
There exists an OpenAI Embeddings wrapper, which you can access with
from langchain.embeddings import OpenAIEmbeddings
For a more detailed walkthrough of this, see this notebook
Tokenizer#
There are several places you can use the tiktoken tokenizer. By default, it is used to count tokens
for OpenAI LLMs.
You can also use it to count tokens when splitting documents with
from langchain.text_splitter import CharacterTextSplitter
CharacterTextSplitter.from_tiktoken_encoder(...)
For a more detailed walkthrough of this, see this notebook
Moderation#
You can also access the OpenAI content moderation endpoint with
from langchain.chains import OpenAIModerationChain | /content/https://python.langchain.com/en/latest/ecosystem/openai.html |

Creating and Executing Tools with yAgents
Yeager.ai#
This page covers how to use Yeager.ai to generate LangChain tools and agents.
What is Yeager.ai?#
Yeager.ai is an ecosystem designed to simplify the process of creating AI agents and tools.
It features yAgents, a No-code LangChain Agent Builder, which enables users to build, test, and deploy AI solutions with ease. Leveraging the LangChain framework, yAgents allows seamless integration with various language models and resources, making it suitable for developers, researchers, and AI enthusiasts across diverse applications.
yAgents#
Low code generative agent designed to help you build, prototype, and deploy Langchain tools with ease.
How to use?#
pip install yeagerai-agent
yeagerai-agent
Go to http://127.0.0.1:7860
This will install the necessary dependencies and set up yAgents on your system. After the first run, yAgents will create a .env file where you can input your OpenAI API key. You can do the same directly from the Gradio interface under the tab “Settings”.
OPENAI_API_KEY=<your_openai_api_key_here>
We recommend using GPT-4,. However, the tool can also work with GPT-3 if the problem is broken down sufficiently.
Creating and Executing Tools with yAgents#
yAgents makes it easy to create and execute AI-powered tools. Here’s a brief overview of the process: | /content/https://python.langchain.com/en/latest/ecosystem/yeagerai.html |
e7cc502160fa-1 | Create a tool: To create a tool, provide a natural language prompt to yAgents. The prompt should clearly describe the tool’s purpose and functionality. For example:
create a tool that returns the n-th prime number
Load the tool into the toolkit: To load a tool into yAgents, simply provide a command to yAgents that says so. For example:
load the tool that you just created it into your toolkit
Execute the tool: To run a tool or agent, simply provide a command to yAgents that includes the name of the tool and any required parameters. For example:
generate the 50th prime number
You can see a video of how it works here.
As you become more familiar with yAgents, you can create more advanced tools and agents to automate your work and enhance your productivity.
For more information, see yAgents’ Github or our docs

Graphsignal#
This page covers how to use Graphsignal to trace and monitor LangChain. Graphsignal enables full visibility into your application. It provides latency breakdowns by chains and tools, exceptions with full context, data monitoring, compute/GPU utilization, OpenAI cost analytics, and more.
Installation and Setup#
Install the Python library with pip install graphsignal
Create free Graphsignal account here
Get an API key and set it as an environment variable (GRAPHSIGNAL_API_KEY)
Tracing and Monitoring#
Graphsignal automatically instruments and starts tracing and monitoring chains. Traces and metrics are then available in your Graphsignal dashboards.
Initialize the tracer by providing a deployment name:
import graphsignal
graphsignal.configure(deployment='my-langchain-app-prod')
To additionally trace any function or code, you can use a decorator or a context manager:
@graphsignal.trace_function
def handle_request():
chain.run("some initial text")
with graphsignal.start_trace('my-chain'):
chain.run("some initial text")
Optionally, enable profiling to record function-level statistics for each trace.
with graphsignal.start_trace(
'my-chain', options=graphsignal.TraceOptions(enable_profiling=True)):
chain.run("some initial text")
See the Quick Start guide for complete setup instructions.

Tips and Next Steps
ClearML Integration#
In order to properly keep track of your langchain experiments and their results, you can enable the ClearML integration. ClearML is an experiment manager that neatly tracks and organizes all your experiment runs.
Getting API Credentials#
We’ll be using quite some APIs in this notebook, here is a list and where to get them:
ClearML: https://app.clear.ml/settings/workspace-configuration
OpenAI: https://platform.openai.com/account/api-keys
SerpAPI (google search): https://serpapi.com/dashboard
import os
os.environ["CLEARML_API_ACCESS_KEY"] = ""
os.environ["CLEARML_API_SECRET_KEY"] = ""
os.environ["OPENAI_API_KEY"] = ""
os.environ["SERPAPI_API_KEY"] = ""
Setting Up#
!pip install clearml
!pip install pandas
!pip install textstat
!pip install spacy
!python -m spacy download en_core_web_sm

from langchain.callbacks import ClearMLCallbackHandler, StdOutCallbackHandler
from langchain.callbacks.base import CallbackManager
from langchain.llms import OpenAI
# Setup and use the ClearML Callback
clearml_callback = ClearMLCallbackHandler(
task_type="inference",
project_name="langchain_callback_demo",
task_name="llm", | /content/https://python.langchain.com/en/latest/ecosystem/clearml_tracking.html |
495dfd8b0173-1 | project_name="langchain_callback_demo",
task_name="llm",
tags=["test"],
# Change the following parameters based on the amount of detail you want tracked
visualize=True,
complexity_metrics=True,
stream_logs=True
)
manager = CallbackManager([StdOutCallbackHandler(), clearml_callback])
# Get the OpenAI model ready to go
llm = OpenAI(temperature=0, callback_manager=manager, verbose=True)
The clearml callback is currently in beta and is subject to change based on updates to `langchain`. Please report any issues to https://github.com/allegroai/clearml/issues with the tag `langchain`.
Scenario 1: Just an LLM#
First, let’s just run a single LLM a few times and capture the resulting prompt-answer conversation in ClearML
# SCENARIO 1 - LLM
llm_result = llm.generate(["Tell me a joke", "Tell me a poem"] * 3)
# After every generation run, use flush to make sure all the metrics
# prompts and other output are properly saved separately

At this point you can already go to https://app.clear.ml and take a look at the resulting ClearML Task that was created. | /content/https://python.langchain.com/en/latest/ecosystem/clearml_tracking.html |
495dfd8b0173-23 | 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.

Could not update last created model in Task 988bd727b0e94a29a3ac0ee526813545, Task status 'completed' cannot be updated
Tips and Next Steps#
Make sure you always use a unique name argument for the clearml_callback.flush_tracker function. If not, the model parameters used for a run will override the previous run!
If you close the ClearML Callback using clearml_callback.flush_tracker(..., finish=True) the Callback cannot be used anymore. Make a new one if you want to keep logging.
Check out the rest of the open source ClearML ecosystem, there is a data version manager, a remote execution agent, automated pipelines and much more!

OpenSearch#
This page covers how to use the OpenSearch ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific OpenSearch wrappers.
Installation and Setup#
Install the Python package with pip install opensearch-py
Wrappers#
VectorStore#
There exists a wrapper around OpenSearch vector databases, allowing you to use it as a vectorstore
for semantic search using approximate vector search powered by lucene, nmslib and faiss engines
or using painless scripting and script scoring functions for bruteforce vector search.
To import this vectorstore:
from langchain.vectorstores import OpenSearchVectorSearch
For a more detailed walkthrough of the OpenSearch wrapper, see this notebook

PGVector#
This page covers how to use the Postgres PGVector ecosystem within LangChain
It is broken into two parts: installation and setup, and then references to specific PGVector wrappers.
Installation#
Install the Python package with pip install pgvector
Setup#
The first step is to create a database with the pgvector extension installed.
Follow the steps at PGVector Installation Steps to install the database and the extension. The docker image is the easiest way to get started.
Wrappers#
VectorStore#
There exists a wrapper around Postgres vector databases, allowing you to use it as a vectorstore,
whether for semantic search or example selection.
To import this vectorstore:
from langchain.vectorstores.pgvector import PGVector
Usage#
For a more detailed walkthrough of the PGVector Wrapper, see this notebook

Banana#
This page covers how to use the Banana ecosystem within LangChain.
It is broken into two parts: installation and setup, and then references to specific Banana wrappers.
Installation and Setup#
Install with pip install banana-dev
Get an Banana api key and set it as an environment variable (BANANA_API_KEY)
Define your Banana Template#
If you want to use an available language model template you can find one here.
This template uses the Palmyra-Base model by Writer.
You can check out an example Banana repository here.
Build the Banana app#
Banana Apps must include the “output” key in the return json.
There is a rigid response structure.
# Return the results as a dictionary
result = {'output': result}
An example inference function would be:
def inference(model_inputs:dict) -> dict:
global model
global tokenizer
# Parse out your arguments
prompt = model_inputs.get('prompt', None)
if prompt == None:
return {'message': "No prompt provided"}
# Run the model
input_ids = tokenizer.encode(prompt, return_tensors='pt').cuda()
output = model.generate(
input_ids,
max_length=100,
do_sample=True,
top_k=50,
top_p=0.95,
num_return_sequences=1,
temperature=0.9,
early_stopping=True,
no_repeat_ngram_size=3,
num_beams=5, | /content/https://python.langchain.com/en/latest/ecosystem/bananadev.html |
01c357036ba6-1 | no_repeat_ngram_size=3,
num_beams=5,
length_penalty=1.5,
repetition_penalty=1.5,
bad_words_ids=[[tokenizer.encode(' ', add_prefix_space=True)[0]]]
)
result = tokenizer.decode(output[0], skip_special_tokens=True)
# Return the results as a dictionary
result = {'output': result}
return result
You can find a full example of a Banana app here.
Wrappers#
LLM#
There exists an Banana LLM wrapper, which you can access with
from langchain.llms import Banana
You need to provide a model key located in the dashboard:
llm = Banana(model_key="YOUR_MODEL_KEY")
