This tutorial shows a full use-case of PyTorch in order to explain several concepts by example. The application will be hand-written number detection using MNIST. MNIST is a popular (perhaps the most popular) educational computer vision dataset. It is composed of 70K images of hand-written digits (0-9) split into 60K-10K training and test sets respectively. The images are tiny (28x28), which makes them easy to work with.
When using PyTorch, there are many ways to load your data. It depends mainly on the type of data (tables, images, text, audio, etc.) and the size. Many text datasets are small enough to load into memory in full. Some image datasets (such as MNIST can also be loaded to memory in full due to the small image size. However, in most real-life applications,
