# MLflow Skill

Expert system for MLflow operations, tracking, and model management.

## When to Use This Skill

This skill should be triggered when:
- Working with MLflow Tracking, Projects, Models, or Registry
- Looking up MLflow API references or feature documentation
- Implementing MLflow integration in machine learning pipelines
- Debugging MLflow-related errors or issues
- Seeking best practices for experiment tracking and model deployment

## Quick Reference

### Common Patterns

**Pattern 1: Install MLflow**
```bash
pip install mlflow
```

**Pattern 2: Command Line Help**
```bash
mlflow --help
```

**Pattern 3: Start UI**
```bash
mlflow ui
```

**Pattern 4: referencing models**
```
models:/<model_name>/<version>
models:/<model_name>/Production
```

**Pattern 5: Log Model (PyTorch example)**
```python
mlflow.pytorch.log_model(model, "model")
```

### Example Code Patterns

**Example 1: Configure S3 Endpoint (Bash)**
```bash
export MLFLOW_S3_ENDPOINT_URL=https://s3.us-west-1.amazonaws.com
```

**Example 2: Set Bucket Owner (Bash)**
```bash
export MLFLOW_S3_EXPECTED_BUCKET_OWNER=123456789012
```

## Reference Files

This skill includes practical documentation in `references/`:

- **ml.md** - Focused guide for tracking, server setup, artifact store, and model registry.

Read specific sections of these files when the user needs detailed explanations.

## usage

### For Beginners
Start by reading the overview or getting started sections in `references/ml.md` to understand the core concepts of Runs, Experiments, and the Tracking Server.

### For API Lookups
Search for the specific function or class name (e.g., `mlflow.log_param`, `mlflow.sklearn.log_model`) within `references/ml.md` to find parameters and usage examples.

### For Troubleshooting
Check the reference documentation for configuration options and common pitfalls, especially regarding authentication and remote server connectivity.
