ENH: <support datatype FP8>

[xiguadong]

Proposed new feature or change:

Hi :
Do you have any plan to support FP8 which proposed in https://arxiv.org/pdf/2209.05433 ?

I don't know of any proposal to include fp8 types in numpy itself, but you might take a look at the ml_dtypes package, which defines several flavors of fp8 dtypes for use with NumPy.

+1 for ml_dtypes here.

We may end up incorporating bfloat16 into numpy itself at some point, but float8 seems like a bridge too far, at least in the near future (and no one has proposed actually doing this anyway). So I'll close this since the question is answered and a solution available. Thanks @xiguadong and @jakevdp
