Lstm backward pass

WebBy default torch.nn.parallel.DistributedDataParallel executes gradient all-reduce after every backward pass to compute the average gradient over all workers participating in the training. If training uses gradient accumulation over N steps, then all-reduce is not necessary after every training step, it’s only required to perform all-reduce after the last call to … Web14 jun. 2024 · # Split in 2 tensors along dimension 2 (num_directions) output_forward, output_backward = torch.chunk (output, 2, 2) Now you can torch.gather the last hidden state of the forward pass using seqlengths (after reshaping it), and the last hidden state of the backward pass by selecting the element at position 0
