개요
Lightning separates model-specific logic from recurring training infrastructure. It helps teams standardize experiments while retaining PyTorch models. Specialized optimization may require understanding framework hooks or choosing the lower-level Fabric approach.

사용 정보
How it works
LightningModule defines model and training logic; Trainer drives execution, precision, devices, and callbacks. Fabric provides more direct loop control.
Audience and requirements
PyTorch research and platform teams. Python, PyTorch, data, and suitable devices.
Practical use cases
Standardized training; reproducible experiments; multi-device projects.
Limitations and selection
Does not prevent data leakage or incorrect metrics. Distributed sampling and aggregation need verification. Hosted services are separate.

모델 호환성 및 사용 사례
Built on PyTorch models; custom optimizer and training behavior must fit the execution interfaces.
