内容概览
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 Original PyTorch code : Lightning version : Benefits : 40+ lines → 15 lines, no device management, automatic distributed Automatic features : - Validation runs every epoch by default - Metrics logged to TensorBoard - Best model checkpointing based on val loss Launch : No changes needed : - Automatic data distribution - Gradient synchronization - Multi-node support (just set num nodes=2) Result : - Auto-saves best 3 models - Stops early if no improvement for 5 epochs - Logs learning rate to TensorBoard Use PyTorch Lightning when : - Want clean, org…
