Answer 1

I had the same problem, I run:

sudo pip install -U scikit-learn

and now everything is working fine

Answer 2

I started a new shell and this problem went away

Answer 3

I faced the similar situation of getting mumurhash error while installing sklearn.preprocessing library.

I upgraded numpy version from 1.13 to 1.15

using

pip install --upgrade numpy

After this, I was able to import the sklearn library.
