pytorch-lightning

pytorch-lightning is a skill for Claude Code from magic3007/dotfiles. It costs 71 tokens per session (1,711 once invoked), scanned A, a copy of pytorch-lightning, MIT.

A framework for organizing and running neural-network training code built with PyTorch, including data handling, logging, callbacks, and distributed training.

In plain words
What is it for?
Use it to structure deep-learning projects, train models across multiple GPUs or TPUs, manage data pipelines, track experiments, and configure large-scale training.
Why use it?
It reduces repeated training-code setup while keeping control over the model and training process.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pytorch-lightning scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/quick_trainer_setup.py, scripts/template_datamodule.py, scripts/template_lightning_module.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PyTorch Lightning

Overview

PyTorch Lightning is a deep learning framework that organizes PyTorch code to eliminate boilerplate while maintaining full flexibility. Automate training workflows, multi-device orchestration, and implement best practices for neural network training and scaling across multiple GPUs/TPUs.

Current upstream: lightning 2.6.4 (PyPI, May 2026). Docs: lightning.ai/docs/pytorch/stable. Use import lightning as L (the pytorch-lightning package name still installs the same library).

Installation

uv pip install lightning

Optional extras:

uv pip install lightning[extra]    # loggers, strategies, etc.
uv pip install wandb mlflow        # specific loggers as needed

When to Use This Skill

This skill should be used when:

  • Building, training, or deploying neural networks using PyTorch Lightning
  • Organizing PyTorch code into LightningModules
  • Configuring Trainers for multi-GPU/TPU training
  • Implementing data pipelines with LightningDataModules
  • Working with callbacks, logging, and distributed training strategies (DDP, FSDP, DeepSpeed)
  • Structuring deep learning projects professionally

Core Capabilities

1. LightningModule - Model Definition

Organize PyTorch models into six logical sections:

  1. Initialization - __init__() and setup()
  2. Training Loop - training_step(batch, batch_idx)
  3. Validation Loop - validation_step(batch, batch_idx)
  4. Test Loop - test_step(batch, batch_idx)
  5. Prediction - predict_step(batch, batch_idx)
  6. Optimizer Configuration - configure_optimizers()

Quick template reference: See scripts/template_lightning_module.py for a complete boilerplate.

Detailed documentation: Read references/lightning_module.md for comprehensive method documentation, hooks, properties, and best practices.

2. Trainer - Training Automation

The Trainer automates the training loop, device management, gradient operations, and callbacks. Key features:

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
