From charlesr.harris at gmail.com Fri Sep 6 20:42:04 2019 From: charlesr.harris at gmail.com (Charles R Harris) Date: Fri, 6 Sep 2019 18:42:04 -0600 Subject: [SciPy-User] NumPy 1.17.2 released. Message-ID: Hi All, On behalf of the NumPy team I am pleased to announce that NumPy 1.17.2 has been released. This release contains fixes for bugs reported against NumPy 1.17.1 along with some documentation improvements. The most important fix is for lexsort when the keys are of type (u)int8 or (u)int16. If you are currently using 1.17 you should upgrade. The Python versions supported in this release are 3.5-3.7, Python 3.8b4 should work with the released source packages, but there are no future guarantees. Downstream developers should use Cython >= 0.29.13 for Python 3.8 support and OpenBLAS >= 3.7 to avoid wrong results on the Skylake architecture. The NumPy wheels on PyPI are built from the OpenBLAS development branch in order to avoid those problems. Wheels for this release can be downloaded from PyPI , source archives and release notes are available from Github . *Contributors* A total of 7 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - CakeWithSteak + - Charles Harris - Dan Allan - Hameer Abbasi - Lars Grueter - Matti Picus - Sebastian Berg *Pull requests merged* A total of 8 pull requests were merged for this release. - #14418: BUG: Fix aradixsort indirect indexing. - #14420: DOC: Fix a minor typo in dispatch documentation. - #14421: BUG: test, fix regression in converting to ctypes - #14430: BUG: Do not show Override module in private error classes. - #14432: BUG: Fixed maximum relative error reporting in assert_allclose. - #14433: BUG: Fix uint-overflow if padding with linear_ramp and negative... - #14436: BUG: Update 1.17.x with 1.18.0-dev pocketfft.py. - #14446: REL: Prepare for NumPy 1.17.2 release.

Can it be possible to help to fix this issue? Or if any build notes you can provide is a great help. In simple steps how to build sciupy??

You may be happier using Docker: http://scipy.github.io/devdocs/dev/contributor/quickstart_docker.html That said, if you want to make the Windows build we can try to help. The above error can have multiple causes, so please put your whole build log in a gist and provide us with a link to it.
