WebbSharded data parallelism is a memory-saving distributed training technique that splits the training state of a model (model parameters, gradients, and optimizer states) across GPUs in a data parallel group. Note Sharded data parallelism is available in the SageMaker model parallelism library v1.11.0 and later. Webbmake model.module accessible, just like DDP. append_shared_param(p: torch.nn.parameter.Parameter) → None [source] Add a param that’s already owned by another FSDP wrapper. Warning This is experimental! This only works with all sharing FSDP modules are un-flattened. p must to be already sharded by the owning module.
