PyTorch Distributed Training Guide

PyTorch’s distributed training is a method of training models in parallel on multiple computing resources, such as multiple GPUs or machines, to speed up the training process and improve efficiency. PyTorch provides a set of tools and APIs for distributed training, such as torch.nn.parallel.DistributedDataParallel and the torch.distributed module, which help users easily train models on multiple devices or machines and manage data distribution and gradient aggregation.
