Pytorch for loop parallel

Python does not have true parallelism within any given process. You would have to spawn a ProcessPool and make the inside of your loop a function taking batch_index, mask_batch, then map that function over the mask object in your current for loop. Thing is, I don't know if PyTorch will play nicely with this. WebSep 23, 2024 · In PyTorch data parallelism is implemented using torch.nn.DataParallel. But we will see a simple example to see what is going under the hood. And to do that we will have to use some of the functions of nn.parallel, namely: Replicate: To replicate Module on multiple devices.
