Types in pure Python sources
by Sergei Lebedev May 3, 2022

May 3, 2022

Hi everyone, I've noticed that NumPy currently users separate type stub files for specifying types for both pure Python and native modules. For example the (untyped) implementation of np.core._asarray is in [1], but the types are in [2]. This works fine for type checkers, and if anything, improves type checking performance, because type stubs are much smaller than their pure Python counterparts. It does, however, create problems for IDEs which now have to either work with untyped APIs or manually merge them with type stubs to provide better coding assistance. Is there a reason for type stubs being separate (other than historical [3])? If not, how should I go about starting a conversation upstream about this? Sergei [1]: https://github.com/numpy/numpy/blob/main/numpy/core/_asarray.py [2]: https://github.com/numpy/numpy/blob/main/numpy/core/_asarray.pyi [3]: https://github.com/numpy/numpy-stubs

PEP 688: Making the buffer protocol accessible in Python
by Jelle Zijlstra April 26, 2022

April 26, 2022

I just posted https://peps.python.org/pep-0688/, which proposes adding a types.Buffer type that will make it possible to check in Python code whether a type implements the buffer protocol. I'm reaching out to the numpy community because numpy was an important driver for creating the buffer protocol. I'd be happy to hear any feedback or possible use cases for the PEP.

April 14, 2022

Hello, all Unfortunately, we (neither NumPy nor SciPy) were not selected this year for Google Season of Docs. You can see the accepted projects here: https://developers.google.com/season-of-docs/docs/participants Thank you all who dedicated time and effort to the proposal. I’m trying to get some feedback from the Season of Docs team on the proposal shortcomings or things we could have done differently. Best, Melissa

Numpy 1.22.4 release date?
by Maarten Ballintijn April 13, 2022

April 13, 2022

Greetings, We are trying to migrate a stack to python 3.10. It looks like numpy-1.22.4 is going to be required to move to python 3.10 because of the cython/debugging issue (https://github.com/numpy/numpy/issues/21008 <https://github.com/numpy/numpy/issues/21008>). Is the release imminent? Where can we find more details? Any insights are appreciated! Thank you, Maarten.

NumFOCUS Contributor Diversification and Retention research project: call for participation
by Melissa Mendonça April 13, 2022

April 13, 2022

Hi folks! I have been asked to share this call for participation with you. I've mentioned this research in community meetings in the past. Please feel free to reach out if you have any questions or concerns. --- NumPy is working with NumFOCUS <http://numfocus.org> on a research project <https://numfocus.org/diversity-inclusion-disc/a-pivotal-time-in-numfocuss-p…> funded by the Gordon & Betty Moore Foundation <https://www.moore.org/> to understand the barriers to participation that contributors, particularly those from historically underrepresented groups, face in the open-source software community. The research team would like to talk to new contributors, project developers and maintainers, and those who have contributed in the past about their experiences joining and contributing to NumPy. Interested in sharing your experiences? Please complete this brief “Participant Interest <https://numfocus.typeform.com/to/WBWVJSqe>” form which contains additional information on the research goals, privacy, and confidentiality considerations. Your participation will be valuable to the growth and sustainability of diverse and inclusive open-source software communities. Accepted participants will participate in a 30-minute interview with a research team member. Thank you for your interest!

NumPy 1.21.6 released
by Charles R Harris April 12, 2022

April 12, 2022

Hi All, On behalf of the NumPy team I am pleased to announce the release of NumPy 1.21.6. NumPy 1.21.6 is a very small release that achieves two things: - Backs out the mistaken backport of C++ code into 1.21.5. - Provides a 32 bit Windows wheel for Python 3.10. The provision of the 32 bit wheel is intended to make life easier for oldest-supported-numpy. The Python versions supported in this release are 3.7-3.10. If you want to compile your own version using gcc-11 you will need to use gcc-11.2+ to avoid problems. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/1.21.6/>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v1.21.6>. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels. A recent version of pip is needed to install the universal2 macos wheels. Cheers, Charles Harris
