The code … WebAug 23, 2024 · Right now, the "least bad practice" for interoperating double-backward use cases (eg gradient penalty) with DDP is using torch.autograd.grad(..., create_graph=True) to create intermediate grads out of place in each process. The returned out-of-place grads are intercepted before they reach allreduce hooks, and therefore hold purely intraprocess ...
