20.10.2021 · Hello everyone. I have 2 datasets for a classification problem. Each has labels of different sizes. I want to sample from both at the same time for every iteration of training. I could do something like: train_dl = DataLoader(trainset_1+trainset_2, shuffle = True, batch_size=128, num_workers=4) But the issue is the mismatch in dimensions of labels and the data loader …

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. Dataset stores the samples and their corresponding labels, and DataLoader wraps an iterable around the Dataset to enable easy access to the samples.
