Fairseq provides several command-line tools for training and evaluating models: fairseq-preprocess: Data pre-processing: build vocabularies and binarize training data. There are numerous applications that may benefit from an accurate multilingual lexical alignment of bi-and multi-language corpora. maybe try out a stand along pytorch small model with distributed training on these 2 nodes cause I feel you probably have some error with network interface and it's unrelated to fairseq. mosesdecoder.

If key is not in The easiest way to launch jobs is with the torch.distributed.launch tool. Could you rerun your script with NCCL_DEBUG=INFO and post the output, please? The error mentions THD, which implies youre using an older version of PyTorch. Ok - do you also recommend no_c10d on a single GPU? 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. I'm experiencing a similar issue to this bug.
