Compatibility issues when adding langchain-openai to project with existing openai package

I’m updating my project to use langchain version 0.2. This version needs separate LLM model installs. I tried to add langchain-openai but it’s not playing nice with my current openai package (version 1.3.5).

When I run pipenv install langchain-openai, I get an error about conflicting dependencies. I’m not sure how to fix this.

I’ve got two options:

  1. Find a langchain-openai version that works with openai==1.3.5
  2. Upgrade openai without breaking my code

I looked on PyPI but couldn’t find clear info about which versions work together. Anyone know how to figure this out? Or have any other ideas to solve this problem?

Here’s a simplified version of what I’m dealing with:

# Current setup
import openai
from langchain import ChatOpenAI

# What I'm trying to do
from langchain_openai import ChatOpenAI

# But it's not working due to version conflicts

Any help would be great. Thanks!

I encountered a similar conflict when updating my project to langchain 0.2. In my case, upgrading both the openai and langchain packages together helped resolve the issue.

I suggest trying the command below:

pipenv install --upgrade openai langchain langchain-openai

This updates openai to its latest version and installs a compatible version of langchain-openai. Note that you might have to make minor changes to your code due to updated import paths and potential breaking changes. If you must stick with openai 1.3.5, consider downgrading langchain to a version that doesn’t require langchain-openai.

I’ve dealt with this exact problem recently. The key is to use compatible versions of both packages. From my experience, langchain-openai 0.0.2 works well with openai 1.3.5. You can try installing it like this:

pipenv install langchain-openai==0.0.2

This should resolve the conflict without requiring you to upgrade openai. If you still encounter issues, you might need to temporarily uninstall openai, install langchain-openai, and then reinstall openai. Just be prepared to update your import statements as needed.

Remember to test thoroughly after making these changes, as even minor version differences can sometimes lead to unexpected behavior in your code.
