Automatic Mixed Precision examples¶. Ordinarily, “automatic mixed precision training” means training with torch.cuda.amp.autocast and torch.cuda.amp.GradScaler together. Instances of torch.cuda.amp.autocast enable autocasting for chosen regions. Autocasting automatically chooses the precision for GPU operations to improve performance while maintaining accuracy.

Aug 04, 2020 · Using PyTorch 1.6 native AMP. This tutorial provides step by step instruction for using native amp introduced in PyTorch 1.6. Often times, its good to try stuffs using simple examples especially if they are related to graident updates. Scientists need to be careful while using mixed precission and write proper test cases.
28.07.2020 · For the PyTorch 1.6 release, developers at NVIDIA and Facebook moved mixed precision functionality into PyTorch core as the AMP package, torch.cuda.amp. torch.cuda.amp is more flexible and intuitive compared to apex.amp. Some of apex.amp’s known pain points that torch.cuda.amp has been able to fix:
Automatic Mixed Precision package - torch.cuda.amp¶. torch.cuda.amp and torch provide convenience methods for mixed precision, where some operations use the torch.float32 (float) datatype and other operations use torch.float16 (half).Some ops, like linear layers and convolutions, are much faster in float16.Other ops, like reductions, often require the dynamic …
Automatic Mixed Precision¶. Author: Michael Carilli. torch.cuda.amp provides convenience methods for mixed precision, where some operations use the torch.float32 (float) datatype and other operations use torch.float16 (half).Some ops, like linear layers and convolutions, are much faster in float16.Other ops, like reductions, often require the dynamic range of float32.
Sep 17, 2020 · PyTorch 1.6.0 native AMP is also much slower compared to 1.5.0+apex.amp. All 3 FP16 AMP configurations with 1.6.0 are slower than FP32. Again, only difference is the PyTorch version in the docker images. Other things common in the images are: cuda 10.1, cudnn 7.6.5.32-1+cuda10.1, python 3.6.8, Do you have any suggestions on this problem? Edit:
28.07.2020 · Hi there, Note that we won't pin the version of PyTorch to 1.6 minimum, so the use of native mixed precision will have to be controlled by a test on the pytorch version (basically use native mixed precision when the version allows it and use apex otherwise).

17.09.2020 · Hi, I’m experiencing strange slow training speed with PyTorch 1.6.0+AMP. I built 2 docker images, and the only difference between them is one have torch 1.5.0+cu101 and the other have torch 1.6.0+cu101. On these two docker images, I ran same code (Huggingface xlmr-base model for token classification) on same hardware (P40 GPU), with no distributed data …
