Fixing definition of reduceat for Numpy 2.0?
by Martin Ling Nov. 24, 2024

Nov. 24, 2024

Hi folks, I don't follow numpy development in much detail these days but I see that there is a 2.0 release planned soon. Would this be an opportunity to change the behaviour of 'reduceat'? This issue has been open in some form since 2006! https://github.com/numpy/numpy/issues/834 The current behaviour was originally inherited from Numeric, and makes reduceat often unusable in practice, even where it should be the perfect, concise, efficient solution. But it has been impossible to change it … [View More]

New matvec and vecmat functions
by Marten van Kerkwijk Nov. 22, 2024

Nov. 22, 2024

Hi All, I have a PR [1] that adds `np.matvec` and `np.vecmat` gufuncs for matrix-vector and vector-matrix calculations, to add to plain matrix-matrix multiplication with `np.matmul` and the inner vector product with `np.vecdot`. They call BLAS where possible for speed. I'd like to hear whether these are good additions. I also note that for complex numbers, `vecmat` is defined as `x†A`, i.e., the complex conjugate of the vector is taken. This seems to be the standard and is what we used for `… [View More]

PR - can I get a new review?
by Jake S. July 23, 2024

July 23, 2024

Hi community, PR 26081 <https://github.com/numpy/numpy/pull/26081> is about making numpy's ShapeType covariant and bound to a tuple of ints. The community has requested this occasionally in issue 16544 <https://github.com/numpy/numpy/issues/16544>. I'm reaching out via the listserv because it's been a few months, and I don't want it to get too stale. I could really use some help pushing it over the finish line. Summary: Two numpy reviewers and one interested community member … [View More]

Condensing _fr0 and _fr1 into one function in getlimits.py
by trevor.depalatis＠gmail.com May 27, 2024

May 27, 2024

Hello! I'm not sure if this is the right place to post, but I'm a first time contributor and I noticed that there might be some code in getlimits.py that could be condensed. It looks like from lines 16-30 there are two functions for fixing rank, "_fr0" and "_fr1", that could turn into one function, given how much code they both share. I'd love to implement this, but am I missing something significant that requires these two to be separate? Thanks for your time, Trevor

Question regarding transitioning native extension to NumPy 2.0
by Pavlyk, Oleksandr May 24, 2024

May 24, 2024

I am working to transition mkl_fft and mkl_random to NumPy 2.0. Both of these projects contain native extensions. I have distilled unexpected behavior behind observed test failures in minimal C extension: https://github.com/oleksandr-pavlyk/reproducer-for-question-about-numpy2 The extension defines a single Python function which does expects numpy.ndarray, and queries its itemsize in two ways 1. By calling C function declared in "_aux.h" defined in "_aux.c" to call PyArray_ITEMSIZE … [View More]

updating the NumPy roadmap
by Ralf Gommers May 24, 2024

May 24, 2024

Hi all, Now that the dust has settled on what we're including in the NumPy 2.0 release, it felt like a good time to update the project roadmap. After a few discussions with other maintainers I opened https://github.com/numpy/numpy/pull/26505. Part of it is a regular maintenance update: remove what we've implemented or decided not to do, and rewrite existing roadmap entries to reflect their current state. The other part is adding some new items. In particular: 1. Under the documentation … [View More]

Hi all, In yesterday's community meeting we discussed the 2.0 release schedule, and concluded that we are far enough along to pick a date for the final 2.0 release.

A quick timeline: - `maintenance/2.0.x` branch creation: March 8 - beta 1: March 12 - release candidate 1: March 30 - release candidate 2: May 12 - as of today, 37 out of 58 of the downstream packages we're currently tracking at https://github.… [View More]
