                sh 'kitops init'
            }
        }
        stage('Data Preprocessing') {
            steps {
                sh 'kitops preprocess --data-source=${DATA_SOURCE} --output=${PROCESSED_DATA}'
            }
        }
        stage('Model Training') {
            steps {
                sh 'kitops train --data=${PROCESSED_DATA} --model-type=${MODEL_TYPE}'
            }
        }
        stage('Model Evaluation') {
            steps {
                sh 'kitops evaluate --model=${TRAINED_MODEL} --test-data=${TEST_DATA}'
            }
        }
        stage('Model Deployment') {
            when {
                expression {
                    currentBuild.resultIsBetterOrEqualTo('SUCCESS')
                }
            }
            steps {
                sh 'kitops deploy --model=${TRAINED_MODEL} --environment=production'
            }
        }
    }
}

This Jenkins pipeline script demonstrates how KitOps commands can be integrated into existing CI/CD workflows, handling everything from data preprocessing to model deployment.

2. Containerization and Environment Management

KitOps leverages containerization to ensure consistency across development, testing, and production environments. Here’s an example Dockerfile that KitOps might generate;

FROM python:3.8-slim

# Install KitOps and dependencies
RUN pip install kitops scikit-learn pandas numpy

# Copy model artifacts
COPY model/ /app/model/

# Set up environment variables
ENV MODEL_PATH=/app/model/trained_model.pkl
ENV SCALING_FACTORS=/app/model/scaling_factors.json

# Run the model server
CMD ["kitops", "serve", "--model=${MODEL_PATH}", "--scaling=${SCALING_FACTORS}"]

This Dockerfile encapsulates the ML model and its dependencies, ensuring that it can be deployed consistently across different environments.

3. Version Control for Models and Data

KitOps extends version control concepts to ML artifacts. It uses a combination of Git for code versioning and specialized tools for model and data versioning. Here’s an example of how model versioning might be implemented;

import kitops

# Initialize model repository
repo = kitops.ModelRepository("my_model_repo")

# Create a new model version
with repo.create_version("v1.0") as version:
    version.add_file("model.pkl", "path/to/model.pkl")
    version.add_metadata({
        "accuracy": 0.95,
        "training_data": "dataset_20220315.csv",
        "hyperparameters": {
            "learning_rate": 0.01,
            "max_depth": 5
        }
    })

# Commit the new version
repo.commit("Initial model version")

This code snippet demonstrates how KitOps can track not only the model file itself but also associated metadata, making it easy to reproduce and compare different versions.

4. Automated Testing and Validation

KitOps includes tools for automated testing of ML models. Here’s an example of how a test suite might be defined;

import kitops
from kitops.testing import ModelTestSuite

class MyModelTestSuite(ModelTestSuite):
    def test_accuracy(self):
        self.assertGreaterEqual(self.model.accuracy, 0.9)
    
    def test_fairness(self):
        self.assertFairnessMetric(self.model, threshold=0.05)
    
    def test_latency(self):
        self.assertInferenceTime(self.model, max_time=100)  # in milliseconds

# Run the tests
kitops.run_tests(MyModelTestSuite, model_path="path/to/model.pkl")

This test suite checks the model’s accuracy, fairness, and inference latency, ensuring that it meets the required standards before deployment.

5. Monitoring and Logging

KitOps provides built-in monitoring and logging capabilities. Here’s an example of how monitoring might be set up;

from kitops.monitoring import ModelMonitor

monitor = ModelMonitor(model_name="customer_churn_predictor")

# Log prediction
monitor.log_prediction(
    input_data=customer_data,
    prediction=churn_probability,
    actual_outcome=actual_churn,
    metadata={
        "customer_segment": "high_value",
        "prediction_timestamp": "2023-03-15T14:30:00Z"
    }
)

# Generate monitoring report
report = monitor.generate_report(start_date="2023-03-01", end_date="2023-03-31")
report.save("monthly_model_performance.pdf")

This code logs individual predictions and generates performance reports, allowing teams to track model behavior in production and identify potential issues.
