The script worked in one of our cloud environments, but not in another and I'm trying to figure out why. Hi Team, As part of distributed training, we are trying out Nvidia Apex library and we took care of Set OMP_NUM_THREADS in torch.distributed.launch issue. Yes, no_c10d is equivalent, just a slightly more robust DDP backend (and a small amount slower). Unfortunately, I don't think I have slurm installed on our cluster nor do I have a root privilege to configure it. Sign in fairseq is an open-source sequence modeling toolkit that allows researchers and developers to train custom models for translation, summarization, language modeling, and other text generation tasks. how to do this).
