ENH: bfloat16 when available?
Same numpy bfloat16 feature request for pandas:

https://github.com/numpy/numpy/issues/17809

Hi,

I saw NEP 41 Status: | Accepted

https://github.com/numpy/numpy/blob/master/doc/neps/nep-0041-improved-dtype-support.rst

I'm just wondering when will bfloat16 be available in numpy?

For some ML problems, this will reduce the memory requirement by half (or process 2x more data), can we give this high priority?

Thanks.
