WebMar 3, 2024 · First of all, the data should be in a different folder per label for the default PyTorch ImageFolder to load it correctly. In your case, since all the training data is in the same folder, PyTorch is loading it as one class and hence learning seems to be working. You can correct this by using a folder structure like - train/dog, - train/cat ... WebFeb 2, 2024 · In general, setting a transform to augment the data without touching the original dataset is the common practice when training neural models. That said, if you need to mix an augmented dataset with the original one you can, for example, stack two datasets with torch.utils.data.ConcatDataset, as follows:
