python - ModuleNotFoundError: No module named 'numpy.testing.nosetester' AND PermissionError: [WinError 5] Access is denied

Question

I am trying to use sklearn in jupyter notebook, but when I use import sklearn (sklearn is already installed) and/or from sklearn import linear_model, it gives me this error:

ModuleNotFoundError: No module named 'numpy.testing.nosetester'

When I try to upgrade numpy and pip, it gives me this error:

You are using pip version 9.0.1, however version 21.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

When I try python -m pip install --upgrade pip in both jupyter notebook and the command prompt, I get the following message.

PermissionError: [WinError 5] Access is denied: 'c:\\programdata\\anaconda3\\lib\\site-packages\\pip\\basecommand.py'

Any help is much appreciated.
