Need a pandas release that supports arm64 on Windows in order to test, which is required before we can release.

First attempt failed due to changes in NumPy's npymath library structure. #xref numpy/numpy#29747

main is now building on win-arm64 Probably won't be on PyPI until the next release, and we will likely need win-arm64 pandas since it is required for the tests.

Ideally it would be sometime this fall, but hard to say. First pandas, then maybe some patches, and only then would be put out a wheel on PYPi. This said,...

There are many failing tests when trying to run on Windows on Arm. I don't have any hardward so would really need someone to work through these failures and find...

Small correction - the failures are actually segfaults. Most appear to be related to models that use the Poisson. I suspect that there is an issue somewhere in SciPy or...

The multinomial generator in the numoy Generator object is vectorized,and iirc supports broadcasting. On Sat, Mar 4, 2023, 21:22 Josef Perktold ***@***.***> wrote: > score_test is missing > > get_distribution:...

I am have similar issues with some packages (statsmodels, arch, linearmodels). Cython coverage worked as expected using setuptools and editable builds. With meson I haven't been able to get coverage....
