torch.cuda. This package adds support for CUDA tensor types, that implement the same function as CPU tensors, but they utilize GPUs for computation.

03.05.2020 · The new backtrace makes sense: some C++ function is receiving mismatched arguments. I'll track down the implementation. If it's a custom autograd function, we'll need to apply torch.cuda.amp.custom_fwd/bwd.If it's a torch backend function, I'll need to add it to the Amp promote list, or possibly the FP32 list or FP16 list, if the op has a preferred precision.
