"TypeError: multiple bases have instance lay-out conflict" when Running notebook in my vscode venv

Short Course Q&A Functions, Tools and Agents with LangChain
1

I’m following the last section of the tutorial on building a chatbot using LangChain, but I’m encountering an error that says TypeError: multiple bases have instance lay-out conflict. I’m unable to proceed because of this issue.

Error Message:

Here’s the complete error traceback for reference:
Traceback (most recent call last):

Environment:

Python Version: [Python version 3.9.7]
LangChain Version: [Your LangChain version 0.0.305]
Pydantic Version: [Pydantic version, 2.4.2]

Is there a workaround this? Are there known compatibility issues?

never mind i was able to find the dependencies through the notebook, will update if I have anymore issues. I am trying to implement this method into creating my own agents.
