These dataclass are similar jobs - much like a Hydra with multiple heads. 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. data-bin/iwslt14.tokenized.de-en. I also reduce the batch size until I get absolutely no OOM error, so that I can avoid training to hang/crash. However, upgrading to PyTorch 1.7.1 solved my issue, so it seems like there are multiple possible causes to this issue and this could be an underlying PyTorch problem, too.
