NumPy 1.15.0rc1 released

Charles R Harris
Hi All,

On behalf of the NumPy team I'm pleased to announce the release of NumPy 1.15.0rc1.
This release has an unusual number of cleanups, many deprecations of old functions,
and improvements to many existing functions. A total of 423 pull reguests were merged
for this release, please look at the release notes for details. Some highlights are:
  • NumPy has switched to pytest for testing.
  • A new  `numpy.printoptions` context manager.
  • Many improvements to the histogram functions.
  • Support for unicode field names in python 2.7.
  • Improved support for PyPy.
The Python versions supported by this release are 2.7, 3.4-3.6.  The wheels are linked with
OpenBLAS 3.0, which should fix some of the linalg problems reported for NumPy 1.14, 
and the source archives were created using Cython 0.28.2 and should work with the upcoming
Python 3.7.

Wheels for this release can be downloaded from PyPI, source archives are available
from Github.

A total of 128 people contributed to this release.  People with a "+" by their
names contributed a patch for the first time.

just checking: in Debian we're currently linking against
libblas/liblapack (as available from http://www.netlib.org/lapack/) -
should we start investigating switching to OpenBLAS?

Thanks!

Yes I'd say so, the performance difference can be very large. I always thought Debian was linking against ATLAS - just because it's available and that's how we always recommended building on Debian/Linux from source. Plain Netlib BLAS/LAPACK is never recommended.

Thanks!

Well, as far as I can tell numpy in Debian is built using the /etc/alternatives method, i.e. you can choose which BLAS implementation to use at run time if more then one implementation is installed. In my case, it links to openblas already:

So, it seems to me there's no problem to solve in Debian?

Ciao!
