[Numpy-discussion] Using OpenBLAS for manylinux wheels

[Olivier Grisel]

I just tested those new openblas-based wheels on the linux virtualbox
setup that I used to report the following segfault back in February:

I cannot reproduce this problem anymore with this new version of
OpenBLAS. All scikit-learn tests pass (I had originally encountered
the segfault when runing the scikit-learn tests). I also ran the numpy
and scipy tests successfully on that machine.

What I find reassuring is that the upstream OpenBLAS has set up a
buildbot based CI to test OpenBLAS on many CPU architectures and is
running the scipy test continuously to detect regressions early on:
