Array API adoption

I am interested in this topic. I've been working on Array API support in scikit-learn and would be interested to talk with other maintainers who are doing similar work in other array consuming libraries. I am also part of the committee working on the standard itself. I am up for comparing notes, discussing warts, working on scikit-learn itself, mentoring others who want to work on Array API support in scikit-learn

For the particle physics people, in addition to engaging in broader community adoption, we (myself and @nsmith-) should also follow up wtih @jpivarski in advance of the Summit on the state and ideas of https://github.com/scikit-hep/ragged for Awkward Array / Array API integration.

Hi everyone. I've been working on laying the groundwork for a special function array API extension and would like to participate in this topic. For some reason I'm not able to assign myself to this issue.

I've been converting scipy.stats to the array API (scipy/scipy#20544) and dispatching scipy.special functions to the appropriate backend (scipy/scipy#19023). Supporting projects include arbitrary precision array API arrays (mparray) and array-API-backend agnostic masked arrays (scipy/scipy#20363); it would be nice to get feedback on whether/how these might be used in the rest of the ecosystem.

Thanks for assigning me @mdhaber

From working on Array API adopting and seeing the progress in Scikit-learn and SciPy, I have noticed a few areas of friction for adoption.

For the summit, I want to write down all the things we learned from adopting the standard. This way, libraries that are interested in consuming the Array API standard can have an easier time.

Some topics to talk about on Monday morning:

• missing functions in the array API standard
• casting/conversion for inputs?
  • e.g. if user inputs ints, should we convert to floating point? should we require the user converts?
• array-api-compat versioning? what to do if users have an old version?
• GitHub GPU CI/testing of array API code
  • eScience has experience running the GitHub GPU runners
• should there be a scipy built on top of array API?
• dispatching
