GuidesDebuggingOn this pageDebuggingIf 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​Platforms with tracing capabilities like LangSmith and WandB 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.langchain.debug and langchain.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_toolsfrom langchain.chat_models import ChatOpenAIllm = 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.'langchain.debug = True​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.import langchainlangchain.debug = Trueagent.run("Who directed the 2023 film Oppenheimer and what is their age?
