WebDec 26, 2024 · If your data fits in memory (in the form of np.array, torch.Tensor, or whatever), just pass that to Dataloader and you’re set. If you need to read data incrementally from disk or transform data on the fly, write your own class implementing __getitem__ () and __len__ (), then pass that to Dataloader. If you really have to use iterable-style ... WebApr 9, 2024 · I just figured out that the torch.nn.LSTM module uses hidden_size (hidden_size * 1 or 2 if bidirectional) to set the 3rd dimension of the output tensor. So in my case, it is always reformatting my input to 64, 20, 64. I just found a bit in the docs that say "unless proj_size > 0". I'm trying that now. At least I've changed the warning message.
