Are you using Bento to build scipy?
by CJ Carey 16 Jul '18

16 Jul '18

With the 1.0 release coming up, I figured this is a good time to take the pulse of the community regarding Bento. The project seems to have been abandoned before reaching stability, and it seems that the core problems it was trying to address have been at least partially fixed by the more official build systems. If you use Bento and would like to keep using it post 1.0, or if my previous sentence is wrong, please let me know!

NumPy 1.13.0rc2 released
by Charles R Harris 18 May '17

18 May '17

Hi All, I'm pleased to announce the NumPy 1.13.0rc2 release. This release supports Python 2.7 and 3.4-3.6 and contains many new features. It is one of the most ambitious releases in the last several years. Some of the highlights and new functions are *Highlights* - Operations like ``a + b + c`` will reuse temporaries on some platforms, resulting in less memory use and faster execution. - Inplace operations check if inputs overlap outputs and create temporaries to avoid problems. - New __array_ufunc__ attribute provides improved ability for classes to override default ufunc behavior. - New np.block function for creating blocked arrays. *New functions* - New ``np.positive`` ufunc. - New ``np.divmod`` ufunc provides more efficient divmod. - New ``np.isnat`` ufunc tests for NaT special values. - New ``np.heaviside`` ufunc computes the Heaviside function. - New ``np.isin`` function, improves on ``in1d``. - New ``np.block`` function for creating blocked arrays. - New ``PyArray_MapIterArrayCopyIfOverlap`` added to NumPy C-API. Wheels for the pre-release are available on PyPI. Source tarballs, zipfiles, release notes, and the changelog are available on github <https://github.com/numpy/numpy/releases/tag/v1.13.0rc2>. A total of 102 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - A.

Hi Developers, I was trying to gain some knowledge about scipy.optimize and was trying to fix #7322 but I am unable to understand what exactly does the scipy.optimize.root() does. There is a lack of resource, can someone suggest me any resources or explain it to me? Thank you

A sort-of-rendered version of the end-user docs can be seen here: https://github.com/numpy/numpy/blob/master/doc/source/reference/arrays.clas… And the NEP has been updated to hopefully provide a more spec-like description of the final version: https://github.com/numpy/numpy/blob/master/doc/neps/ufunc-overrides.rst Note that the API is "provisional" in 1.13, i.e. it *might* change in backwards-incompatible ways: https://docs.python.org/3/glossary.html#term-provisional-api -n -- Nathaniel J.

Failing PR with time-out on CircleCI Sphinx document generation
by Blair Azzopardi 08 May '17

08 May '17

Hi I've submitted a PR (https://github.com/scipy/scipy/pull/7374) and it's failing CI while generating Sphinx documentation with a time out ( https://circleci.com/gh/scipy/scipy/2726). I've not been able to replicate this issue on my setup. Can anyone offer suggestions on what changes I can make to the PR to pass this test? Thanks Blair
