SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires lightning, torch, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Organizes PyTorch code into LightningModule and LightningDataModule patterns to simplify scalable training and reproducibility.

Core Features & Use Cases

  • Organize model and data logic using LightningModule and LightningDataModule for clean separation of concerns.
  • Simplify training orchestration with the Trainer, including multi-GPU/TPU, distributed strategies, and automatic optimization.
  • Integrates with a wide ecosystem of loggers and callbacks for experiment tracking and monitoring.

Quick Start

Train a CNN on MNIST by wrapping the data in a LightningDataModule, the model in a LightningModule, and calling Trainer to run the training.

Frequently Asked Questions about pytorch-lightning

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I organize PyTorch code to simplify scalable training and reproducibility?▼

You can organize PyTorch code by structuring model logic into LightningModule and data logic into LightningDataModule, separating concerns to simplify scalable training and reproducibility.

How do I set up distributed training across multiple GPUs using PyTorch?▼

Set up distributed training by configuring the Lightning Trainer with distributed strategies like DDP, FSDP, or DeepSpeed to handle multi-GPU and multi-device orchestration automatically.

Can I use custom callbacks and loggers for experiment tracking with Lightning Trainer?▼

Yes, the Lightning Trainer integrates with a wide ecosystem of loggers and callbacks, allowing you to inject custom monitoring and experiment tracking logic into the training loop.

Do I need to manually manage optimizers and schedulers when using Lightning?▼

No, you configure optimizers and schedulers within the LightningModule, and the Lightning Trainer handles the automatic optimization orchestration, reducing manual loop management overhead.

What is the best way to scale a PyTorch model from single-device to multi-device setups?▼

The best way to scale is wrapping your model in a LightningModule and passing it to the Trainer, which abstracts single-device and multi-device distributed setups including DDP and FSDP.
