Description

I'm trying to use the Langchain (mostly loaders, core and community) with Microsoft's GraphRAG, but when I try to install both of them together, I get

Because no versions of graphrag match >0.3.0,<0.4.0
 and graphrag (0.3.0) depends on tenacity (>=9.0.0,<10.0.0), graphrag (>=0.3.0,<0.4.0) requires tenacity (>=9.0.0,<10.0.0).
And because langchain-community (0.2.12) depends on tenacity (>=8.1.0,<8.4.0 || >8.4.0,<9.0.0)
 and no versions of langchain-community match >0.2.12,<0.3.0, graphrag (>=0.3.0,<0.4.0) is incompatible with langchain-community (>=0.2.12,<0.3.0).
So, because celery-projeto depends on both langchain-community (^0.2.12) and graphrag (^0.3.0), version solving failed.

Are any plans for Langchain update tenacity to 9.0.0?

System Info

Currently, LangChain depends on Tenacity ^=8.1.0,!=8.4.0. By changing this to >=8.1.0, it should be possible to install Tenacity 9.0.0, which I believe will resolve this issue.

langchain/libs/community/pyproject.toml

Line 39 in 583b044

tenacity = "^8.1.0,!=8.4.0"

Same issue now, with graphrag requiring >9.0.0

#26088

We opened an PR that may solve this issue: #27201

[plasmas]

As PR #27201 has been merged, langchain@0.3.3 and langchain-core@0.3.10 show no dependency complaints when installing graphrag@0.3.6. langchain-community has also been updated, but will probably need to wait for 0.3.3 (currently 0.3.2) to be released before the changes are in effect.

Edit: PR #27201 is not yet included in langchain@0.3.3, langchain-core@0.3.10 or langchain-community@0.3.2. Need to wait for the next release for all of them.

As a temporary workaround, it is possible to clone the langchain repo add packages as local dependencies
