What problem does it solve?
This Skill removes the complexity of running machine learning training across multiple GPUs or multiple machines by coordinating Ray clusters, workers, and recovery automatically.
Core Features & Use Cases
- Distributed training orchestration: Run PyTorch, TensorFlow, or HuggingFace training jobs from a single script and scale them across many nodes.
- Hyperparameter tuning: Launch parallel experiment sweeps with Ray Tune and stop weak trials early to save compute.
- Fault-tolerant execution: Resume from checkpoints, recover failed workers, and keep long-running jobs stable in production environments.
- Use Case: A research team can start with a local prototype, then move the same training logic to a multi-node cloud cluster for faster iteration and larger model runs.
Quick Start
Use the ray-train skill to plan and configure a distributed training job for my PyTorch or HuggingFace model, including cluster setup, scaling, checkpointing, and tuning.
