Checklist

• I added a very descriptive title to this issue.
• I included a link to the documentation page I am referring to (if applicable).

Issue with current documentation:

there exist a lot of import error, one such is
TypeError: cannot pickle 'classmethod' object even when i am simply importing from the codeblock on langchain which goes like --> from langchain_experimental.agents.agent_toolkits import create_pandas_dataframe_agent

link -->https://python.langchain.com/v0.2/docs/integrations/tools/pandas/

Idea or request for content:

if the version has recently changed it could have been mentioned on site, otherwise a guide to handle such errors would have been good.

I had the same problem.

It's because of the langchain migration to v0.3.

Try
pip install --upgrade langchain_openai
pip install --upgrade langchain

It worked for me !
