Originally created by @smannathan on GitHub (Sep 30, 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

N/A

Error Message and Stack Trace (if applicable)

"/opt/homebrew/lib/python3.10/site-packages/langgraph/checkpoint/serde/jsonplus.py", line 29, in <module>
    from langgraph.store.base import Item
ModuleNotFoundError: No module named 'langgraph.store.base'

Description

I encountered a ModuleNotFoundError when running a script that imports langgraph.store.base. It seems that the module is missing from the installed package, even though langgraph is installed.

System Info

langgraph==0.2.29
langgraph-checkpoint==1.0.13

@smannathan could you try creating a virtual environment from scratch and see if the issue persists?

Just updated to the latest release (hoping it would fix an issue with passing state to tools and getting a pydantic validation error), and hit this on top of it.

EDIT: @vbarda that seemed to do the trick. Killed my VE and recreated and it worked as expected.

great, happy it's working. we're also pushing a quick fix in the next update to make sure folks don't need to make a new venv

I updated the requirements.txt to install checkpoint first and then langgraph.

langgraph-checkpoint==1.0.13
langgraph==0.2.29

It is working fine now.

hi all -- the issue is fixed in langgraph-checkpoint==1.0.14 and doesn't require clearing the venv. let me know if you run into any issues

@vbarda Hey, I pinned my dependency to 1.0.14 and I get the following error:

Any advice what I could do without pinning the upper bound to "langgraph-checkpoint<=1.0.12"?

@maxschulz-COL you should either use latest langgraph version (>=0.2.29) or pin langgraph-checkpoint <=1.0.12. hope this helps!
