Have a question about this project? The no_c10d backend is more robust since it only communicates at the end of the backward pass, but there are still limits to this kind of recovery.

Fairseq is a sequence modeling toolkit written in PyTorch that allows researchers and developers to train custom models for translation, summarization, language modeling and other text generation tasks. Such a procedure has become the de facto standard in NLP with models like BERT [2]. For example, instead of preprocessing all your data into a single data-bin Usually this causes it to become stuck when the workers are not in sync. Here is what I do (I wrote the port number 12356 in YAML), and also adding a line cfg.distributed_training.device_id = int(os.environ["LOCAL_RANK"]) to distributed/utils.py -> call_main() as the project can no longer accept --local_rank from torch.distributed.launch. components inherit from FairseqTask and FairseqModel and provide a dataclass But I think this line cfg.distributed_training.device_id = int(os.environ["LOCAL_RANK"]) is necessary when using torchrun, without it, the device_id will always be 0, resulting in multiple processes being assigned to the same device.
