WebDP和DDP. pytorch中的有两种分布式训练方式，一种是常用的DataParallel(DP)，另外一种是DistributedDataParallel(DDP)，两者都可以用来实现数据并行方式的分布式训练，DP采用的是PS模式，DDP采用的是ring-all-reduce模式，两种分布式训练模式主要区别如下： WebDistributedDataParallel (DDP) implements data parallelism at the module level which can run across multiple machines. Applications using DDP should spawn multiple processes and create a single DDP instance per process. DDP uses collective communications in the torch.distributed package to synchronize gradients and buffers.
