Code for processing data samples can get messy and hard to maintain; we ideally want our dataset code to be decoupled from our model training code for better readability and modularity. PyTorch 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.

05.09.2019 · I am confused about the Subset() for torch.dataset. I have a list of indices and a pytorch dataset (e.g. cifar). When I used the indices to get a subset from the dataset, the new subset.dataset still keeps the same length as the original dataset, even though when it is loaded into a dataloader, the length becomes correct.

23.04.2018 · The index is specific to a Dataset and you can return it in the __getitem__ function. The DataLoader just calls the __getitem__ function from its Dataset and iterates it using the specified batch size. I don’t think there is an easy way to modify a DataLoader to return the index. At least, I don’t have an idea, sorry.
