WebJul 8, 2024 · The closest to a MWE example Pytorch provides is the Imagenet training example. Unfortunately, that example also demonstrates pretty much every other feature Pytorch has, so it’s difficult to pick out what pertains to distributed, multi-GPU training. Apex provides their own version of the Pytorch Imagenet example.
