WebApr 12, 2024 · Manual calling of prepare_data, which downloads and parses the data and setup, which creates and loads the partitions, is necessary here because we retrieve the data loader and iterate over the training data. Instead, one may pass the data module directly to the PyTorch Lightning trainer class, which ensures that prepare_data is called exactly ... WebPyTorch provides two data primitives: torch.utils.data.DataLoader and torch.utils.data.Dataset that allow you to use pre-loaded datasets as well as your own data. Dataset stores the samples and their corresponding labels, and DataLoader wraps an iterable around the Dataset to enable easy access to the samples.

WebDec 22, 2024 · Host to GPU copies are much faster when they originate from pinned (page-locked) memory. You can set pin memory to True by passing this as an argument in DataLoader: torch.utils.data.DataLoader (dataset, batch_size, shuffle, pin_memory = True) It is always okay to set pin_memory to True for the example I explained above.
