def __init__(self):
self.models = {}
self.metrics = {}
self.deployment_history = []
def train_model(self, model_name, training_data, hyperparameters):
"""
Train model with automatic versioning and tracking
"""
# Version control
version = f"{model_name}_v{len(self.models.get(model_name, [])) + 1}"
# Training with monitoring
model = self._train_with_monitoring(
training_data, hyperparameters
)
# Automated testing
test_results = self._run_tests(model, version)
# Store model and metadata
self.models[model_name] = self.models.get(model_name, [])
self.models[model_name].append({
'version': version,
'model': model,
'hyperparameters': hyperparameters,
'test_results': test_results,
'timestamp': pd.Timestamp.now()
})
return version
def deploy_model(self, model_name, version, deployment_config):
"""
Deploy model with canary release and monitoring
"""
# Validate model exists
model_info = self._get_model(model_name, version)
# Canary deployment
deployment = {
'model': model_name,
'version': version,
'config': deployment_config,
'status': 'canary',
'traffic_percentage': 10,
'timestamp': pd.Timestamp.now()
}
# Monitor performance
self._setup_monitoring(deployment)
# Gradual rollout based on metrics
self.deployment_history.append(deployment)
return deployment
def monitor_performance(self, model_name, metrics):
"""
Continuous monitoring and alerting
"""
current_deployment = self._get_current_deployment(model_name)
# Check for model drift
drift_detected = self._detect_drift(metrics)
# Performance degradation check
performance_issues = self._check_performance(metrics)
if drift_detected or performance_issues:
self._trigger_retraining(model_name)
self._send_alert(model_name, metrics)
# Log metrics
self.metrics[model_name] = self.metrics.get(model_name, [])
self.metrics[model_name].append({
'timestamp': pd.Timestamp.now(),
'metrics': metrics,

# Usage example
mlops = MLOpsPipeline()
# version = mlops.train_model('fraud_detector', training_data, hyperparams)
# mlops.deploy_model('fraud_detector', version, deployment_config)
