Checklist:

• PR title: Please title your PR "package: description", where "package" is whichever of langchain, community, core, experimental, etc. is being modified. Use "docs: ..." for purely docs changes, "templates: ..." for template changes, "infra: ..." for CI changes.
  • Example: "community: add foobar LLM"
• PR message: Delete this entire template message and replace it with the following bulleted list
  • Description: a description of the change
  • Issue: the issue # it fixes, if applicable
  • Dependencies: any dependencies required for this change
  • Twitter handle: if your PR gets announced, and you'd like a mention, we'll gladly shout you out!
• Pass lint and test: Run make format, make lint and make test from the root of the package(s) you've modified to check that you're passing lint and testing. See contribution guidelines for more information on how to write/run tests, lint, etc: https://python.langchain.com/docs/contributing/
• Add tests and docs: If you're adding a new integration, please include
  1. a test for the integration, preferably unit tests that do not rely on network access,
  2. an example notebook showing its use. It lives in docs/docs/integrations directory.

Additional guidelines:

• Make sure optional dependencies are imported within a function.
• Please do not add dependencies to pyproject.toml files (even optional ones) unless they are required for unit tests.
• Most PRs should not touch more than one package.
• Changes should be backwards compatible.
• If you are adding something to community, do not re-import it in langchain.
