WitrynaThe torchvision.transforms module offers several commonly-used transforms out of the box. The FashionMNIST features are in PIL Image format, and the labels are integers. For training, we need the features as normalized tensors, and the labels as one-hot encoded tensors. To make these transformations, we use ToTensor and Lambda. …
