https://github.com/pytorch/pytorch/pull/33743  67 give a nice touch on the sub-8-bit quantization. However, if I want to do some 1-bit quantization which quantizes the feature map and weight matrices into {-1, 1}.  This may requires further changes in the qscheme. I am guessing that will require me add some PyTorch intrinsics in ATen? Or there is a better way to accomendate that need?
In any case, I am looking forward to see 33743 67 land soon.
