Hi,
Olivier Grisel and I are working on building and testing manylinux
wheels for numpy and scipy.
We first thought that we should use ATLAS BLAS, but Olivier found that
my build of these could be very slow [1]. I set up a testing grid [2]
which found test errors for numpy and scipy using ATLAS
I just tested those new openblas-based wheels on the linux virtualbox
setup that I used to report the following segfault back in February:

Matthew,
I ran the tests after installing the wheels on my machine running
Ubuntu 14.04. Three numpy tests failed with the GFORTRAN_1.4 error you
mentioned in post to the
The problem with the gfortran failures will be tackled by renaming the
vendored libgfortran.so library, see:
https://github.com/pypa/auditwheel/issues/24
This is orthogonal to the ATLAS vs OpenBLAS decision though.

On Nix/NixOS we've been using OpenBLAS 0.2.14 for some time now because we
had some segmentation faults with 0.2.15 and scipy/scikitlearn. I've tested
the packages you listed, and more, with OpenBLAS 0.2.17 and encountered no
problems.

If OpenBLAS is looking like the easiest to support solution, then no
objections here. (If 0.2.17 is genuinely working well, then maybe we want
to switch to it on Windows too. I know Xianyi disabled some of the
problematic kernels for us -- maybe that's enough. Mostly I just don't want
to end up in

Yes sorry I forgot to update the thread. Actually I am no longer sure
how I go this error. I am re-running the full test suite because I
cannot reproduce it when running the test_stats.py module alone.

I updated the issue:

The random test_nanmedian_all_axis failure is unrelated to openblas
and should be ignored.
