WebThe DataLoader works with all kinds of datasets, regardless of the type of data they contain. For this tutorial, we’ll be using the Fashion-MNIST dataset provided by TorchVision. We use torchvision.transforms.Normalize () to zero-center and normalize the distribution of the image tile content, and download both training and validation data splits. Web1 Look at random_split in torch.utils.data. It will handle a random Dataset split (you have to split before creating the DataLoader, not after).
