Evaluating Pre-trained Models fairseq 0.9.0 documentation (AKA, are models trained with and without c10d equivalent?). Thanks for replying back. Ok - do you also recommend no_c10d on a single GPU? needed to create a component is to initialize its dataclass and overwrite some 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. 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.
