WebAutomatic 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 or bfloat16.Other ops, like reductions, often require the … WebMar 3, 2024 · Gradient clipping ensures the gradient vector g has norm at most c. This helps gradient descent to have a reasonable behaviour even if the loss landscape of the model is irregular. The following figure shows an example with an extremely steep cliff in the loss landscape. mn phy ed standardsWeb1 Answer Sorted by: 4 torch.nn.utils.clip_grad_norm_ performs gradient clipping. It is used to mitigate the problem of exploding gradients, which is of particular concern for recurrent networks (which LSTMs are a type of). Further details can be found in the original paper.
