WebPyTorch provides many tools to make data loading easy and hopefully, makes your code more readable. In this recipe, you will learn how to: Create a custom dataset leveraging the PyTorch dataset APIs; Create callable custom transforms that can be composable; and Put these components together to create a custom dataloader.
