stackoverflow.com › questions › 66370250
Feb 25, 2021 · The data loader takes your specified batch_size and makes n calls to the __getitem__ method in the torch data set, applying the transform to each sample sent into training/validation. It then collates n samples into your batch size emitted from the data loader. Hopefully above makes sense to you.

https://pytorch.org/tutorials/beginner/basics/data_tutorial.html
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.

torchvision.transforms — Torchvision 0.11.0 documentation
https://pytorch.org/vision/stable/transforms.html
torchvision.transforms¶. Transforms are common image transformations. They can be chained together using Compose.Most transform classes have a function equivalent: functional transforms give fine-grained control over the transformations. This is useful if you have to build a more complex transformation pipeline (e.g. in the case of segmentation tasks).
