ProvidersMoreWandB TracingWandB TracingThere are two recommended ways to trace your LangChains:Setting the LANGCHAIN_WANDB_TRACING environment variable to "true".Using a context manager with tracing_enabled() to trace a particular block of code.Note if the environment variable is set, all code will be traced, regardless of whether or not it's within the context manager.import osos.environ["LANGCHAIN_WANDB_TRACING"] = "true"# wandb documentation to configure wandb using env variables# https://docs.wandb.ai/guides/track/advanced/environment-variables# here we are configuring the wandb project nameos.environ["WANDB_PROJECT"] = "langchain-tracing"from langchain.agents import initialize_agent, load_toolsfrom langchain.agents import AgentTypefrom langchain.llms import OpenAIfrom langchain.callbacks import wandb_tracing_enabled# Agent run with tracing.
