PyTorch Lightning Overview PyTorch Lightning is a deep learning framework that organizes PyTorch code to eliminate boilerplate while maintaining full flexibility. Automate training workflows, multi-device orchestration, and implement best practices for neural network training and scaling across multiple GPUs/TPUs. When to Use This Skill This skill should be used when: - Building, training, or deploying neural networks using PyTorch Lightning - Organizing PyTorch code into LightningModules - Configuring Trainers for multi-GPU/TPU training - Implementing data pipelines with LightningDataModules…
