2015-10-01 Cannot import DLL

I just tried:

import scipy
import scipy.stats

But it failed with an error:

DLL load failed

The error happened again when using scikit-learn. As both modules are using numpy, I suspected than this one was not properly installed. It usually happens on Windows when you upgrade a module which takes a dependency on it:

pip install <module> --upgrade

pip notices that numpy has to be updated. Unfortunately, many modules only accepts the MKL compilation available here: Unofficial Windows Binaries for Python Extension Packages:

pip uninstall numpy
pymy_install3 numpy
