Congrats to all on the release.Two questions:

Is there a guide to building standard wheels for NumPy?

I don't think so - there is a repository that we use to build the wheels, that has the Windows, OSX and manyllinux recipes for the standard CPython build:

https://github.com/MacPython/numpy-wheelso

If you can work out a way to automate the PyPy builds and tests - especially using the same repo - that would be very useful.

Assuming I can build standardized PyPy 2.7 wheels for Ubuntu, Win32 and OSX64, how can I get them blessed and uploaded to PyPI?

If you can automate the build and tests, I'm guessing there will be no objections - but it's not my call...

I'm in favor, assuming that the wheel tags and PyPy backwards compatibility situation is OK. Can't really find any examples. What I mean is that for CPython wheels contain tags like "cp27" or "cp35". PyPy wheels should have tags "pp<something>". Are the PyPy cpyext layer and the <something> defined such that a new PyPy release won't break older wheels?

Another thing to think about is that 1.12 on pypy won't pass its test suite (though it's close), and we're not yet testing new PRs on pypy, so no guarantees about 1.13 yet. I think on balance these probably aren't reasons *not* to upload wheels, but it's a funny place where we're talking about providing "official" builds even though it's not an "officially supported platform". So we will at least want to be clear about that. And someone will have to handle the bug reports about the test suite failing :-). -n

Since the NumPy API is forwards compatible, you should use the oldest version of NumPy you would like to support to build your wheels with. The wheels will then work with any future NumPy versions. On Fri, Nov 18, 2016 at 9:30 AM Peter Cock wrote:

I have a related question to Matti's,

Do you have any recommendations for building standard wheels for 3rd party Python libraries which use both the NumPy Python and C API?

e.g. Do we need to do anything special given the NumPy C API itself is versioned? Does it matter compiler chain should we use?

Thanks

Peter

Hi All,

I'm pleased to annouce the release of NumPy 1.12.0b1. This release supports Python 2.7 and 3.4 - 3.6 and is the result of 388 pull

requests

...

submitted by 133 contributors. It is quite sizeable and rather than put the release notes inline I've attached them as a file and they may also be viewed at Github<https://github.com/numpy/numpy/releases/tag/v1.12.0b1 . Zip files and tarballs may also be found the Github link. Wheels and source archives may be downloaded from PyPI, which is the recommended method.

This release is a large collection of fixes, enhancements, and improvements and it is difficult to select just a few as highlights. However, the following enhancements may be of particular interest

- Order of operations in ``np.einsum`` now can be optimized for large speed improvements. - New ``signature`` argument to ``np.vectorize`` for vectorizing with core dimensions. - The ``keepdims`` argument was added to many functions. - Support for PyPy 2.7 v5.6.0 has been added. While not complete,
