Version of pandas is incompatible with numpy < 1.20.3
Try this.
pip install --force-reinstall numpy
and then
pip install numpy==1.20.3
I kept getting error: ImportError: this version of pandas is incompatible with numpy < 1.20.3 your numpy version is 1.18.5. Please upgrade numpy to >= 1.20.3 to use this pandas version
And I'm unable to update, remove, and reinstall numpy.
I tried pip install numpy and pip3 install numpy and kept getting this error: AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'
Edit: I tried pip install --force-reinstall numpy and pip install numpy==1.20.3 and still got AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'
