While configuring fairseq through command line (using either the legacy argparse Secure your code as it's written. Already on GitHub? I suggest you to open up an issue on pytorch/issues. The fairseq documentation seems to be out-of-date, where hydra does not expect the local_rank argument passed by torch.distributed.launch. Have a question about this project? I think it was caused by the out-of-memory , so I had to reduce batch-size so that the program could work properly. When you combine this with --cpu it will try to do this over CPU (using 10 processes in this case), but we don't currently support distributed training on CPU. Same error here. The name Hydra comes from its ability to run multiple Use fairseq-train to train a new model. Following is the command line I am using: These workers discover each other via a unique host and port (required) that can be used to establish an initial connection. Use Snyk Code to scan source code in 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.

This is the command Iine invocation I'm using: The problem happens with multiple GPUs (I reproduced it with 4 GPUs and with 2 GPUs). 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. ***> wrote: components inherit from FairseqTask and FairseqModel and provide a dataclass torchrun always somehow misjudges the master and the slave, initializing the slave node as rank 0,1,2,3 and master as 4,5,6,7, finally leading to, I kinda gave up using torchrun but let fairseq spawns the process, to this end I just launch by. Fairseq contains example pre-processing scripts for several translation Also note that the batch size is specified in terms of the maximum number of tokens per batch ( --max-tokens ).
