Originally created by @harupy on GitHub (Oct 1, 2024).

Checked other resources

  • I added a very descriptive title to this issue.
  • I searched the LangGraph/LangChain documentation with the integrated search.
  • I used the GitHub search to find a similar question and didn't find it.
  • I am sure that this is a bug in LangGraph/LangChain rather than my code.
  • I am sure this is better as an issue rather than a GitHub discussion, since this is a LangGraph bug and not a design question.

Example Code

from langgraph.prebuilt import create_react_agent

Your package version and issue seem to be the same; it might be the same problem.

I'm not familiar with the release process and unsure if I can modify previous release dependencies or roll back certain releases.

I think there might be a few solutions:

  1. Limit the maximum dependency of langgraph-checkpointer to 1.0.12 for all past versions containing the langgraph.store folder.
  2. Change versions of langgraph-checkpointer after 1.0.13 to start from 2.0.0, preventing old versions from upgrading to incompatible versions.
  3. Move the store folder from langgraph-checkpointer to the checkpointer folder within langgraph-checkpointer.
  4. Advise users of old versions to manually fix the langgraph-checkpointer version.
@gbaian10 commented on GitHub (Oct 1, 2024): > I think #1834 was the trigger. Prior to this commit, `langgraph-checkpoint` only had `langchain/checkpoint`, but it now has `langgraph/checkpoint` and `langgraph/store`. `langgraph==0.2.16` also has `langgraph/store`, which conflicts with `langgraph-checkpoint`'s `langgraph/store`. This namespace collision issue relates to [pypa/pip#4625](https://github.com/pypa/pip/issues/4625). ![image](https://github.com/user-attachments/assets/f2b3476a-6be3-4d29-9eac-cdabef6505b5) I'm not familiar with the release process and unsure if I can modify previous release dependencies or roll back certain releases. I think there might be a few solutions: 1. Limit the maximum dependency of `langgraph-checkpointer` to 1.0.12 for all past versions containing the `langgraph.store` folder. 2. Change versions of `langgraph-checkpointer` after 1.0.13 to start from 2.0.0, preventing old versions from upgrading to incompatible versions. 3. Move the `store` folder from `langgraph-checkpointer` to the `checkpointer` folder within `langgraph-checkpointer`. 4. Advise users of old versions to manually fix the `langgraph-checkpointer` version.

Option 3 seems reasonable. langgraph-checkpointer should only have the langchain/checkpointer diretory.

Hi all; apologies for this issue - I will be more careful to follow semver to avoid this type of scenario in the future.

The issue occurs if langgraph-checkpoint is upgraded without upgrading langgraph.

Option 3 seems reasonable. langgraph-checkpointer should only have the langchain/checkpointer diretory.

Considering that option 3 might be a design consideration, I think one approach is to release version 0.1.15 (identical to 0.1.12), then release the current contents of 0.1.14 as 2.0.0.
Additionally, release langgraph==0.2.32 and set the minimum dependency on langgraph-checkpointer to 2.0.0.

It seems that more than one person is using version 0.2.16. Not sure if it's for the following reasons.
I recall that after version 0.2.17, Pregel (the base class of CompiledStateGraph) is no longer a BaseModel.
Perhaps this is why they chose to stick with this version?

Since langgraph updates very quickly, I generally use the latest version to benefit from new features.

We have decided to yank yesterday's versions and follow proper semver by bumping lagngraph, langgraph-checkpoint, and other impacted libraries.

Thank you all for your continued patience.

Hi all, we released new versions of langgraph==0.2.32 and langgraph-checkpoint==2.0.0 to address these issues.

  • if you'd like to use the latest version of both libraries, please upgrade to langgraph==0.2.32
  • if you'd like to stay on earlier versions of the libraries, please install langgraph<=0.2.28

I am going to close this issue but please let us know if you're still having issues!
