How did you install numpy, scipy and scikit-learn?
I guess using wheels for all (and not compiling anything) should work.
Or use anaconda.
Also make sure all the libraries you are installing work in the same
python environment.

My operating system is OS X Yosemite version 10.10.5.
numpy version: 1.10.4
scipy version: 0.17.0
scikit-learn version: 0.17.1
I used pip install -U scikit-learn.
I've tried uninstalling and reinstalling scipy (and numpy) and
scikit-learn, but I still get the same error. I appreciate any help
in how I can get a working installation of scikit-learn.
Thank you,
Laura
