WebOrdinarily, “automatic mixed precision training” uses torch.cuda.amp.autocast and torch.cuda.amp.GradScaler together. This recipe measures the performance of a simple network in default precision, then walks through adding autocast and GradScaler to run the same network in mixed precision with improved performance. WebpyTorch Modules class transformer_engine.pytorch.Linear(in_features, out_features, bias=True, **kwargs) Applies a linear transformation to the incoming data y = x A T + b On NVIDIA GPUs it is a drop-in replacement for torch.nn.Linear. Parameters: in_features ( int) – size of each input sample. out_features ( int) – size of each output sample.
