ANN: Python-Blosc2 3.0.0 release candidate 1 is out!
by Francesc Alted Nov. 28, 2024

Nov. 28, 2024

Announcing Python-Blosc2 3.0.0-rc1 ================================== The Blosc development team is pleased to announce the first release release of Python-Blosc2 3.0.0. In this release, we have focused on the making of a compute engine that can work with compressed data in a NumPy-like fashion. You can think of Python-Blosc2 3.0 as a replacement of numexpr, but better :-) As always, we would like to get feedback from the community before the final release. We are providing binary wheels that … [View More]

numpy defaults to free-threaded version on conda-forge
by george trojan Nov. 26, 2024

Nov. 26, 2024

My apologies if this is a wrong venue. Is this a conda-forge problem? When I run mamba create -n foo meson-python numpy 'python>=3.13' the free-threaded python is selected: + python 3.13.0 h6355ac2_0_cp313t conda-forge Cached + numpy 2.1.3 py313hb01392b_0 conda-forge Cached When python spec is moved to the front, I do get the "usual" version. However, when I build a python extension with conda-build, I do not control the order. The extension … [View More]

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]
