[](https://opensource.org/licenses/MIT)
**Transform pipeline graphs into production-ready SageMaker pipelines automatically.**
Cursus is an intelligent pipeline generation system that automatically creates complete SageMaker pipelines from user-provided pipeline graphs. Simply define your ML workflow as a graph structure, and Cursus handles all the complex SageMaker implementation details, dependency resolution, and configuration management automatically.
## 🚀 Quick Start
### Installation
```bash
# Core installation
pip install cursus
# With ML frameworks
pip install cursus[pytorch,xgboost]
# Full installation with all features
pip install cursus[all]
```
### 30-Second Example
```python
import cursus
from cursus.core.dag import PipelineDAG
# Create a simple DAG
dag = PipelineDAG(name="fraud-detection")
dag.add_node("data_loading", "CRADLE_DATA_LOADING")
dag.add_node("preprocessing", "TABULAR_PREPROCESSING")
dag.add_node("training", "XGBOOST_TRAINING")
dag.add_edge("data_loading", "preprocessing")
dag.add_edge("preprocessing", "training")
# Compile to SageMaker pipeline automatically
pipeline = cursus.compile_dag(dag)
pipeline.start() # Deploy and run!
```
### Command Line Interface
```bash
# Generate a new project
cursus init --template xgboost --name fraud-detection
# Validate your DAG
cursus validate my_dag.py
# Compile to SageMaker pipeline
cursus compile my_dag.py --name my-pipeline --output pipeline.json
```
## ✨ Key Features
### 🎯 **Graph-to-Pipeline Automation**
- **Input**: Simple pipeline graph with step types and connections
- **Output**: Complete SageMaker pipeline with all dependencies resolved

## 📚 Usage Examples
### Basic Pipeline
```python
from cursus import PipelineDAGCompiler
from cursus.core.dag import PipelineDAG
# Create DAG
dag = PipelineDAG()
dag.add_node("load_data", "DATA_LOADING_SPEC")
dag.add_node("train_model", "XGBOOST_TRAINING_SPEC")
dag.add_edge("load_data", "train_model")
# Compile with configuration
compiler = PipelineDAGCompiler(config_path="config.yaml")
pipeline = compiler.compile(dag, pipeline_name="my-ml-pipeline")
```
### Advanced Configuration
```python
from cursus import create_pipeline_from_dag
# Create pipeline with custom settings
pipeline = create_pipeline_from_dag(
dag=my_dag,
pipeline_name="advanced-pipeline",
config_path="advanced_config.yaml",
quality_requirements={
"min_auc": 0.88,
"max_training_time": "4 hours"
}
)
```
### Fluent API (Advanced)
```python
from cursus.utils.fluent import Pipeline
# Natural language-like construction
pipeline = (Pipeline("fraud-detection")
.load_data("s3://fraud-data/")
.preprocess_with_defaults()
.train_xgboost(max_depth=6, eta=0.3)
.evaluate_performance()
.deploy_if_threshold_met(min_auc=0.85))
```
