All of the above solutions use Callbacks under the hood to log intermediate steps of components. There's a number of Callbacks relevant for debugging that come with LangChain out of the box, like the FileCallbackHandler. You can also implement your own callbacks to execute custom functionality.See here for more info on Callbacks, how to use them, and customize them.PreviousSQL Question Answering Benchmarking: ChinookNextDeploymentTracinglangchain.debug and langchain.verboselangchain.debug = Truelangchain.verbose = TrueChain(..., verbose=True)Other callbacksCommunityDiscordTwitterGitHubPythonJS/TSMoreHomepageBlogCopyright Â© 2023 LangChain, Inc.
