This is a collection of PyTorch snippets that have helped me (and others) significantly with doing ML research.

• Minimal CIFAR-10 A very simple training script to get 94% accuracy with just ~150 lines of code, for an easy but strong baseline.
• FastMNIST: a drop-in replacement for the standard MNIST dataset which speeds up training on the GPU (by 2x !) by avoiding unnecessary preprocessing that pegs the cpu at 100% for small models.
• Subset of ImageNet: it's remarkably difficult to train on a subset of the ImageNet classes with the default TorchVision datasets. This snippet makes the minimal changes to them to make it very easy.
• ImageNet dogs vs not dogs: a standardized setup for the ImageNet Dogs vs Not Dogs out-of-distribution detection task.

In a separate repository, Slurm for ML, I explain how I use slurm job arrays without pain using a simple 1 file shell script.
