Here, we briey describe the three methods with the highest performance. 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. Furthermore, there aren't any logs / checkpoints -- have you seen something like this before? The toolkit is based on PyTorch and supports distributed training across multiple GPUs and machines. Have a question about this project?
