Issue Description

In the development environment, after I type python and then do import pandas, I get a lot of errors. I didn't get this before and I made sure to run the git reset --hard upstream/main first.

Expected Behavior

No errors

Installed Versions

Replace this line with the output of pd.show_versions()

You can try deleting your build folder to see if that helps.

Your Cython version also might be too old, try installing the latest version.

[shriyakalakata]

@lithomas1 Thank you for responding promptly! I tried both (my previous version of Cython was 3.0.9 and now is 3.0.10). I'm still facing the same issue.

Hi @shriyakalakata can you share the steps what you tried?

[lithomas1]

Can you try deleting your build folder? Should be build, which lives under your main pandas directory.

[shriyakalakata]

@priyapandey26 It was fixed by doing the following steps:

• delete the build folder
• git clean by running git clean -xfd .
• rebuild by running the python -m pip install -ve . --no-build-isolation --config-settings editable-verbose=true command
