# Metaflow-Ray
### Introduction
`metaflow-ray` is an extension for Metaflow that enables seamless integration with Ray, allowing users to easily leverage
Ray's powerful distributed computing capabilities within their Metaflow flows.
With `metaflow-ray`, you can spin up transient Ray clusters on AWS Batch directly from your Metaflow steps using
the `@metaflow_ray` decorator. This enables you to run your Ray applications that leverage Ray Core, Ray Train, Ray Tune,
and Ray Data effortlessly within your Metaflow flow.
### Features
- Effortless Ray Integration: This extension provides a simple and intuitive way to incorporate Ray
into your Metaflow workflows using the `@metaflow_ray` decorator
- Transient Ray Clusters: Let Metaflow orchestrate the creation of transient Ray clusters on top of AWS Batch multi-node parallel jobs
- Seamless Ray Initialization: The `@metaflow_ray` decorator handles the initialization of the Ray cluster for you, so you just need to
focus on writing your Ray code without worrying about cluster setup
- Wide Range of Applications: Run a wide variety of Ray applications, including hyperparameter tuning, distributed data processing, and
distributed training
### Installation
You can install `metaflow-ray` via `pip` alongside your existing Metaflow installation:
```
pip install metaflow-ray
```
### Getting Started
1. Import the `@metaflow_ray` decorator to enable integration:
```python
from metaflow import metaflow_ray
```
2. Decorate your step with `@metaflow_ray`
```python
@step
def start(self):
self.next(self.train, num_parallel=NUM_NODES)
@metaflow_ray
@batch(**RESOURCES)
@step
def train(self):
# Your step's training code here
```
3. Initialize Ray within Your Step
```python
@metaflow_ray
@batch(**RESOURCES)
@step
def train(self):
import ray
ray.init()
# Your ray application code here
```
### Examples
Check out the [examples](/examples) directory for sample Metaflow flows that demonstrate how to use the `metaflow-ray`extension
with various Ray applications.
