PyTorch Lightning Assistant

Organizes PyTorch code into LightningModules, Trainers and DataModules, with multi-GPU strategies and experiment logging.

Dev & CodingIntermediate★ 33,030⑂ 3,248AI score 9/10Last updated: Aug 9, 2026

What it does

  • Refactors raw PyTorch code into a LightningModule with six clear sections (init, training/validation/test steps, predict, optimizers).
  • Configures the Trainer: multi-GPU/TPU, mixed precision, gradient accumulation and clipping, checkpointing, early stopping.
  • Encapsulates data pipelines in a LightningDataModule and wires up W&B, TensorBoard, MLflow or CSV loggers.
  • Recommends distributed strategies by model size: DDP (<500M params), FSDP (500M+), DeepSpeed for fine-grained control.
  • Ships runnable templates plus per-component reference docs the assistant reads on demand.

Who it's for

  • ML engineers cutting boilerplate out of hand-written PyTorch training loops.
  • Researchers scaling single-GPU experiments to multiple GPUs or nodes.
  • Teams standardizing experiment tracking and checkpoint policies.

Example uses

  1. "Port the epoch loop in train.py to a LightningModule" → clean model/step separation.
  2. "How do I train a 1.3B-param model on 4 GPUs?" → FSDP strategy with Trainer args and precision settings.
  3. "Keep the best checkpoint by val_loss and stop after 5 stagnant epochs" → ModelCheckpoint + EarlyStopping code.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/K-Dense-AI/scientific-agent-skills/HEAD/skills/pytorch-lightning/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the skills/pytorch-lightning folder from the GitHub repo K-Dense-AI/scientific-agent-skills into my ~/.claude/skills/pytorch-lightning/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/K-Dense-AI/scientific-agent-skills.git /tmp/sas && mkdir -p ~/.claude/skills && cp -r /tmp/sas/skills/pytorch-lightning ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/K-Dense-AI/scientific-agent-skills.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy just this skill: cp -r scientific-agent-skills/skills/pytorch-lightning ~/.claude/skills/
  5. Install the library in your Python env: pip install lightning (optionally pip install wandb mlflow).
  6. Restart Claude Code and ask something like "restructure my training script with PyTorch Lightning" to trigger the skill.
