29.11.2021 · Hello, I am trying to implement the DistributedDataParallel class in my training code. The training code is a block in a larger block that I run to do the training and logging. Because the larger block runs twice when the multiprocess initialization method is set to ‘spawn’ and rewriting my ‘main’ function would be too much work, I looked into forking the subprocess, so only the ...
