reducing effort spent on wheel builds?
by Ralf Gommers Aug. 9, 2021

Aug. 9, 2021

Hey all, This whole thread is quite interesting: https://twitter.com/zooba/status/1415440484181417998. Given how much effort we are spending on really niche wheel builds, I’m wondering if we should just draw a line somewhere: - we do what we do now for the main platforms: Windows, Linux (x86, aarch64), macOS, *but*: - no wheels for ppc64le - no wheels for Alpine Linux - no wheels for PyPy - no wheels for Raspberry Pi, AIX or whatever other niche thing comes next. - … [View More]

Hi All, I am working <https://github.com/numpy/numpy/pull/19355> on a new UFunc, ` bit_count <https://en.wikipedia.org/wiki/Hamming_weight>` (popcount in other languages) that aims to count the number of 1-bits in the absolute value of an Integer. Implementation ---------------------------------- The primary reference for the implementation is CountBitsSetParallel <http://graphics.stanford.edu/~seander/bithacks.html#CountBitsSetParallel>. Here we take 12 operations to … [View More]

Plan for a new Indexing how-to document
by Mukulika Pahari Aug. 2, 2021

Aug. 2, 2021

Hi, all! I'm planning to write a how-to doc for ndarray indexing as per discussion in https://github.com/numpy/numpy/pull/19407. I have opened a discussion issue (https://github.com/numpy/numpy/issues/19586) with a few ideas and would love to know your opinions on them and other use-cases you'd like to see in the doc. Thank you! Mukulika Pahari
