ray-train
Distributed training orchestration across clusters. Scales PyTorch/TensorFlow/HuggingFace from laptop to 1000s of nodes. Built-in hyperparameter tuning with Ray Tune, fault tolerance, elastic scaling. Use when training massive models across multiple machines or running distributed hyperparameter sweeps.

# Ray Train - Distributed Training Orchestration
## Quick start
Ray Train scales machine learning training from single GPU to multi-node clusters with minimal code changes.
**Installation**:
```bash
pip install -U "ray[train]"
```
**Basic PyTorch training** (single node):
```python
