Might I propose Arkouda?

https://github.com/Bears-R-Us/arkouda https://chapel-lang.org/presentations/Arkouda_SIAM_PP-22.pdf

Have they improved recently to support more than 1D arrays?

@TomNicholas @keewis ```python import ramba import numpy as np import xarray

ra1 = ramba.random.randn(10,20) xa1 = xarray.DataArray(ra1) np1 = xa1.data.asarray() print("np1:", np1) print("xa1.data:", xa1.data, type(xa1.data), xa1.data.dtype, type(xa1.data.dtype))

xa2 = xa1 + 10.0 xa22 = xa2 * 7.1 xa3 = np.sin(xa22) xa4 = xa3.transpose() xa5 = xa4.sum() print("xa5:", xa5, type(xa5)) ```

Using the __array_function__ API and other functions (and not my ill-conceived PR that added ramba to xarray for direct support) , I was able to run the above example. Originally, there were a couple parts of the NumPy API that ramba didn't previously support and I added those. The most difficult of those was 0d arrays. Those are working at least well enough now for the above example so now like I said in the meeting, I'd like even more complicated examples to explore.

Can anybody suggest or provide one?

@keewis Thanks for the note. I originally tried that approach I thought but after this PR I went back and tried again and made more progress so I'm closing this PR.
