[SOLVED] python 3.6 virtualenv

python 3.6 virtualenv - openblas crashes

I'm running on Win7 64 bit, and have created a virtualenv with Python 3.6.

For a start, I've installed the latest numpy from pypi (numpy-1.16.2-cp36-cp36m-win_amd64). However, even just importing numpy will result in python.exe crashing with:

I've found an alternative package that seems to work for numpy: numpy+mkl.

But I have a similar issue with lifelines, which also crashes in libopenblas and for which no alternative seems available. So I'd ideally need to fix whatever is wrong with openblas on my machine, but I've found very little information about what could be going wrong here.

Has anyone seen this kind of issue before, or has an idea how to fix this?
