What problem does it solve?

PyTorch code can be verbose and brittle when scaling from a single machine to multi-GPU or multi-node environments. PyTorch Lightning provides a high-level Trainer and LightningModule that reduces boilerplate while preserving flexibility, enabling scalable, reproducible training.

Core Features & Use Cases

Automatic distributed training (DDP, FSDP, DeepSpeed) with minimal code changes.
Deterministic training loops, mixed precision, gradient accumulation, checkpointing, and rich callbacks.
Use cases include rapid experimentation, production-ready training pipelines, and scalable research workflows across CPU, single-GPU, and multi-GPU clusters.

Quick Start

Install PyTorch Lightning, wrap your model in a LightningModule and Trainer, then train with trainer.fit.

FAQPage Schema

How do I scale PyTorch training across multiple GPUs without writing boilerplate code?▼

To scale PyTorch training across multiple GPUs without boilerplate, wrap your model in a LightningModule and use the high-level Trainer to automatically handle distributed training, mixed precision, and gradient accumulation.

Does PyTorch Lightning support multi-node distributed training strategies like FSDP and DeepSpeed?▼

Yes, PyTorch Lightning supports multi-node distributed training strategies like FSDP and DeepSpeed. The Trainer enables automatic distributed training with minimal code changes, preserving flexibility for scalable research workflows.

What is the best way to reduce boilerplate when building a PyTorch training pipeline?▼

The best way to reduce boilerplate in a PyTorch training pipeline is using Lightning's LightningModule and Trainer. This enforces deterministic training loops, handles checkpointing automatically, and manages comprehensive logging via optional callbacks.

Can I use automatic mixed precision and gradient accumulation for PyTorch training on a single GPU?▼

Yes, you can use automatic mixed precision and gradient accumulation for PyTorch training on a single GPU. Lightning's Trainer manages these features natively, enabling rapid experimentation from CPU to multi-GPU clusters.

Why does my PyTorch code become brittle when moving from a single machine to multi-GPU environments?▼

PyTorch code becomes brittle in multi-GPU environments because native scaling requires manual orchestration. Lightning solves this by providing a high-level Trainer that standardizes the training loop and abstracts distributed strategy configuration.

Do I need to manually configure logging and checkpointing for a scalable PyTorch training pipeline?▼

No, you do not need to manually configure logging and checkpointing for a scalable PyTorch training pipeline. Lightning's Trainer enforces deterministic training loops and provides rich callbacks for comprehensive logging and automatic checkpointing.
