## 🔧 Installation

### Install from PyPI (Recommended)

```bash
pip install mlops-boilerplate
```

### Create a New Project

After installation, create a new ML project using the template:

```bash
# Create a new project
ml-create-project my-ml-project

# Navigate to your project
cd my-ml-project

# Set up virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\\Scripts\\activate

# Install dependencies
pip install -r requirements.txt

# Configure environment
cp .env.example .env
# Edit .env with your configuration
```

### Install from Source (For Development)

```bash
# Clone the repository
git clone https://github.com/kython220282/MLOps-Boilerplate.git
cd MLOps-Boilerplate

# Create virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\\Scripts\\activate

# Install in development mode
pip install -e .
```

### Install with Docker

```bash
docker build -t mlops-boilerplate .
docker run -p 8000:8000 mlops-boilerplate
```

## 🏃 Quick Start

### 1. Setup Environment

```bash
# Copy environment template
cp .env.example .env

# Edit .env with your configuration
```

### 2. Train a Model

```bash
# Using CLI
ml-train --config config/training_config.json

# Or with Python
python -m ml_service.applications.training --config config/training_config.json
```

### 3. Run Inference

```bash
ml-inference --model-path models/model.joblib \\
             --input-path data/test.csv \\
             --output-path predictions.csv
```

### 4. Start API Server

```bash
ml-serve --model-path models/model.joblib --port 8000
```

## 💡 Usage Examples

### Training with Different Data Sources

**From CSV File:**
```python
from ml_service.machine_learning.training_pipeline import TrainingPipeline

config = {
    "data_source": {"type": "file", "path": "data/train.csv"},
    "target_column": "target",
    "model": {"type": "random_forest", "n_estimators": 100},
    "task_type": "classification"
}

pipeline = TrainingPipeline(config)
metrics = pipeline.run_pipeline()
```

**From Database:**
```python
config = {
    "data_source": {
        "type": "database",
        "connector_type": "postgresql",
        "connection_config": {
            "host": "localhost",
            "database": "ml_db"
        },
        "query": "SELECT * FROM training_data"
    },
    "target_column": "target"
}
```

### Custom Model Development

```python
from ml_service.machine_learning.model import BaseModel

class CustomModel(BaseModel):
    def build_model(self):
        # Your model architecture
        pass
    
    def train(self, X_train, y_train):
        # Training logic
        pass
    
    def predict(self, X):
        # Prediction logic
        pass
```

### Data Processing Pipeline

```python
from ml_service.machine_learning.data_processor import DataProcessor

processor = DataProcessor()
df = processor.load_data("data/train.csv")
X_train, X_test, y_train, y_test = processor.preprocess_pipeline(
    df, target_column="target"
)
```

## ⚙️ Configuration

  "model": {
    "type": "random_forest",
    "n_estimators": 100,
    "max_depth": 10
  },
  "data_processing": {
    "missing_value_strategy": "mean",
    "scaling_method": "standard"
  },
  "cross_validation": {
    "type": "kfold",
    "n_splits": 5
  }
}
```
