ImportError: numpy.core._multiarray_umath failed to import

Hello,

There’s a bunch of packages which I’m installing that requires NumPy (for example TensorFlow), and I can’t seem to be able to install and import them because of an ImportError on the numpy side.

This is happening with both pip install and building from source.

Reproducing code example:

import numpy as np
import tensorflow as tf

Error message:

ImportError: numpy.core._multiarray_umath failed to import

Numpy/Python version information:

'1.16.0.dev0+cdbf35b'
