WebbIf you use the Hugging Face Trainer, as of transformers v4.2.0 you have the experimental support for DeepSpeed's and FairScale's ZeRO features. The new --sharded_ddp and --deepspeed command line Trainer arguments provide FairScale and DeepSpeed integration respectively. Here is the full documentation.

Webb18 feb. 2024 · There are different accelerators for training, and while DDP (DistributedDataParallel) runs the script once per GPU, ddp_spawn and dp doesn't. However, certain plugins like DeepSpeedPlugin are built on DDP, so changing the accelerator doesn't stop the main script from running multiple times. Share Improve this … Webb25 mars 2024 · Researchers have included native support for Fully Sharded Data-Parallel (FSDP) in PyTorch 1.11, which is currently only accessible as a prototype feature. Its implementation is significantly influenced by FairScale’s version but with more simplified APIs and improved efficiency. JOIN the fastest ML Subreddit Community.
Webb2 maj 2024 · FSDP precisely addresses this by sharding the optimizer states, gradients and model parameters across the data parallel workers. It further facilitates CPU offloading … 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.
