ImportError: cannot import name 'moduleTNC' - python

Question

I'm having a problem in python when I try to import linear_model from sklearn library: from sklearn import linear_model. I have just installed it via pip simply in this way: pip install sklearn. I know that to avoid this error suffices uninstall and reinstall sklearn, but it didn't work. I also installed it via conda but opening the idle (is that correct?) it gives the same error. How to avoid it? NB: If I use jupyter from conda it works well as it should.

Answer 1

I had this same problem and resolved it with:

conda remove scipy scikit-learn -y
conda install scipy scikit-learn -y

I saw it here, where many other people said it solved their problems too.

Answer 2

With regards to the following error:

ImportError: cannot import name 'moduleTNC'

It can be solved by renaming moduletnc.cp36-win_amd64.pyd with moduleTNC.cp36-win_amd64.pyd in:
