Pytorch Lightning
원문: pytorch-lightning
High-level PyTorch framework with Trainer class, automatic distributed training (DDP/FSDP/DeepSpeed), callbacks system, and minimal boilerplate. Scales from laptop to supercomputer with same code. Use when you want clean training loops with built-in best practices.

PyTorch Lightning High Level Training Framework Quick start PyTorch Lightning organizes PyTorch code to eliminate boilerplate while maintaining flexibility. Installation : Convert PyTorch to Lightning (3 steps): That's it! Trainer handles: GPU/TPU/CPU switching Distributed training (DDP, FSDP, DeepSpeed) Mixed precision (FP16, BF16) Gradient accumulation Checkpointing Logging Progress bars Common workflows Workflow 1: From PyTorch to Lightning Original PyTorch code : Lightning version : Benefits : 40+ lines → 15 lines, no device management, automatic distributed Workflow 2: Validation and testing Automatic features : Validation runs every epoch by default Metrics logged to TensorBoard Best m…
