WebDec 16, 2024 · When using DDP, one optimization is to save the model in only one process and then load it to all processes, reducing write overhead. This is correct because all processes start from the same parameters and gradients are synchronized in backward passes, and hence optimizers should keep setting parameters to the same values. WebMar 27, 2024 · The error DDP is reporting is strange, because it indeed looks like the model is the same across rans. Before initializing the NCCL process group, could you try torch.cuda.set_device (rank % torch.duda.device_count ()) to ensure NCCL uses a different device on each process? ercoargante (Erco Argante) March 28, 2024, 10:18am 3
