Answer 1

I had the same problem. I had originally installed scikit-learn by:

sudo apt-get install python-sklearn

When none of the other solutions posted here worked, I decided to uninstall my version of scikit-learn and reinstall it:

pip2 install --user --install-option="--prefix=" -U scikit-learn  

Used pip2 because I have two versions of python, so I use scikit-learn in Python 2.7

Answer 2

On a related note, this has been posted as a bug on the official Github page, along with some additional solutions, basically suggesting the same solutions as above. Long story short: run a make clean to get rid of the .so file.

Answer 4

I solve this problem by :

pip uninstall scikit-learn

and don't forget to rm the 'sklearn' folder in the python 'site-packages'

rm -rf /path/Python-2.7.5/lib/python2.7/site-packages/sklearn/

then reinstall the package:

pip install scikit-learn

Answer 5

Uninstalling scikit-learn and reinstalling it was the only option that worked for me:

 pip uninstall scikit-learn
 pip install scikit-learn

Answer 6

I encountered the same issue in Mac Os.

I solved it by deleting the file manually:

rm /usr/local/lib/python2.7/site-packages/sklearn/utils/sparsefuncs.so
