While the manylinux PEP brings Linux up to comparable standing with Windows and Mac OS X in terms of distributing wheel files through PyPI, that does mean it still suffers from the same problem Windows does in relation to NumPy and SciPy wheels: no standardisation of the SSE capabilities of the machines. I figured that was independent of the manylinux PEP (since it affects Windows as well), but I'm also curious as to the current status (I found a couple of apparently relevant threads on the NumPy list, but figured it made more sense to just ask for an update rather than trusting my Google-fu) Cheers, Nick. P.S. I'm assuming the existing ability to publish NumPy & SciPy wheels for Mac OS X is based on Apple's tighter control of their hardware platform. -- Nick Coghlan | ncoghlan@gmail.com | Brisbane, Australia
