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.
Ordinarily, “automatic mixed precision training” uses torch.cuda.amp.autocast and torch.cuda.amp.GradScaler together, as shown in the Automatic Mixed Precision examples and Automatic Mixed Precision recipe . However, autocast and GradScaler are modular, and may be used separately if desired. Autocasting Gradient Scaling Autocast Op Reference

Automatic Mixed Precision for Deep Learning Deep Neural Network training has traditionally relied on IEEE single-precision format, however with mixed precision, you can train with half precision while maintaining the network accuracy achieved with single precision. This technique of using both single- and half-precision representations is referred to as mixed precision technique. Benefits of ...

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.
automatic mixed-precision quantization framework designed for BERT that can simultaneously con-duct quantization and pruning in a subgroup-wise level. Specifically, our proposed method leverages Differentiable Neural Architecture Search to assign scale and precision for parameters in each sub-group automatically, and at the same time prun-
Oct 27, 2019 · Mixed precision training utilizes half-precision to speed up training, achieving the same accuracy as single-precision training using the same hyper-parameters. When using automatic mixed precision, memory requirements are also reduced, allowing larger models and minibatches.
