Stability issues and errors encountered when trying to use older langchain and anthropic libraries. - **Dependencies:** - langchain_anthropic version 0.1.4\ - anthropic package version in the range ">=0.17.0,<1" to support langchain_anthropic. - **Twitter handle:** @d_w_b7 - [ x]**Add tests and docs**: If you're adding a new integration, please include 1. used instructions in the README for testing - [ x] **Lint and test**: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified. See contribution guidelines for more: https://python.langchain.com/docs/contributing/ 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.
