Train a CNN with PyTorch DDP

The hands-on Part 2 to the DDP explainer: training a CNN image classifier across several NVIDIA T4 GPUs on Kaggle with PyTorch DistributedDataParallel, over CIFAR-10's 60,000 32x32 images in ten classes. It walks the imports for torch.distributed and TorchVision, then a three-block convolutional architecture with batch normalisation, pooling and fully connected classification, plus the scaffolding for the distributed helper functions.
