looks great, thanks @Xia-Weiwen , can you help move these two int4 tensors as well:

int4_opaque_tensor.py and int4_plain_int32_tensor.py

@Xia-Weiwen if you mark this as bc-breaking, you'll need to write a bc-breaking note

I think it's fine to skip as well since it's probably not widely used yet since it's relatively new, but adding a bc-breaking note sounds fine as well.

Thanks for the heads up. To make things easier, let me just change the label to "not user facing".

Sure.

Hi @liangan1 Could you please take int4_plain_int32_tensor.py ? Thanks.

@jerryzh168 int4 for xpu should be some mature features, I am not sure why we need to move it into the prototype? int4_plain_int32_tensor.py
