Hi all,
I'd like to share an update on this topic. The draft array API standard is now ready for wider review:
- Blog post: https://data-apis.org/blog/array_api_standard_release <https://data-apis.org/blog/array_api_standard_release/> - Array API standard document: https://data-apis.github.io/array-api/latest/ - Repo: https://github.com/data-apis/array-api/
It would be great if people - and in particular, NumPy maintainers - could have a look at it and see if that looks sensible from a NumPy perspective and whether the goals and benefits of adopting it are described clearly enough and are compelling.
I think it is compelling for a first version. The test suite and benchmark suite will be valuable tools. I hope future versions standardize complex numbers as a dtype.
Yes, that's definitely a desire - when implementations are there/ready. At the moment most libraries have very incomplete support for complex dtypes, largely because they're not very important for deep learning. Also NumPy's implementations/choices are shaky in places, and that's being turned up by the PyTorch effort that's ongoing now to implement complex dtype support in a NumPy-compatible way. I realize there is a limit to
the breadth of the scope of functions to be covered. Is there a page that lists them in one place? For instance I tried to look up what the standard has to say on issue https://github.com/numpy/numpy/issues/17760 about using bincount on unt64 arrays. It took me a while to figure out that bincount was not in the API (although unique(..., return_counts) is).
That's a good idea and still missing, thanks for asking. The test suite that's in development has a complete list [1]. In the document itself Sphinx search works, but it should be easier to get a complete overview perhaps (although it requires some thought - the NumPy docs don't have everything on one page either).
