MLflow Experiment Tracker

Integrate with MLflow for comprehensive ML experiment tracking, model registry operations, and artifact management.

Overview

This skill provides capabilities for interacting with MLflow's tracking server and model registry. It enables automated experiment logging, run comparison, model versioning, and artifact retrieval within ML workflows.

Capabilities

Experiment Management

  • Create and manage experiments
  • Start and end runs programmatically
  • Set experiment tags and descriptions
  • List and search experiments

Parameter and Metric Logging

  • Log hyperparameters for reproducibility
  • Track metrics during training (loss, accuracy, etc.)
  • Log batch metrics with timestamps
  • Set run tags for organization

Artifact Management

  • Log model artifacts (serialized models, checkpoints)
  • Store datasets and data samples
  • Save plots and visualizations
  • Retrieve artifacts from completed runs

Model Registry Operations

  • Register trained models
  • Manage model versions
  • Transition models between stages (Staging, Production, Archived)
  • Add model descriptions and tags

Run Comparison and Analysis

  • Compare metrics across runs
  • Search runs by parameters/metrics
  • Retrieve best performing runs
  • Generate comparison visualizations

Prerequisites

MLflow Installation

bash
pip install mlflow>=2.0.0

MLflow Tracking Server

Configure tracking URI:

python
import mlflow
mlflow.set_tracking_uri("http://localhost:5000")  # or remote server

Optional: MLflow MCP Server

For enhanced LLM integration, install the MLflow MCP server:

bash
pip install mlflow>=3.4  # Official MCP support
# or
pip install mlflow-mcp   # Community server

Usage Patterns

Starting an Experiment Run

python
import mlflow

# Set experiment
mlflow.set_experiment("my-classification-experiment")

# Start run with context manager
with mlflow.start_run(run_name="baseline-model"):
    # Log parameters
    mlflow.log_param("learning_rate", 0.01)
    mlflow.log_param("batch_size", 32)
    mlflow.log_param("epochs", 100)

    # Log metrics during training
    for epoch in range(100):
        train_loss = train_one_epoch()
        mlflow.log_metric("train_loss", train_loss, step=epoch)

    # Log final metrics
    mlflow.log_metric("accuracy", 0.95)
    mlflow.log_metric("f1_score", 0.93)

    # Log model artifact
    mlflow.sklearn.log_model(model, "model")

Searching and Comparing Runs

python
import mlflow

# Search runs with filter
runs = mlflow.search_runs(
    experiment_names=["my-classification-experiment"],
    filter_string="metrics.accuracy > 0.9",
    order_by=["metrics.accuracy DESC"],
    max_results=10
)

# Get best run
best_run = runs.iloc[0]
print(f"Best run ID: {best_run.run_id}")
print(f"Best accuracy: {best_run['metrics.accuracy']}")

Model Registry Operations

python
import mlflow

# Register model from run
model_uri = f"runs:/{run_id}/model"
mlflow.register_model(model_uri, "production-classifier")

# Transition model stage
client = mlflow.tracking.MlflowClient()
client.transition_model_version_stage(
    name="production-classifier",
    version=1,
    stage="Production"
)

# Load production model
model = mlflow.pyfunc.load_model("models:/production-classifier/Production")

Integration with Babysitter SDK

Task Definition Example

javascript
const mlflowTrackingTask = defineTask({
  name: 'mlflow-experiment-tracking',
  description: 'Track ML experiment with MLflow',

  inputs: {
    experimentName: { type: 'string', required: true },
    runName: { type: 'string', required: true },
    parameters: { type: 'object', required: true },
    metrics: { type: 'object', required: true },
    modelPath: { type: 'string' }
  },

  outputs: {
    runId: { type: 'string' },
    experimentId: { type: 'string' },
    artifactUri: { type: 'string' }
  },

  async run(inputs, taskCtx) {
    return {
      kind: 'skill',
      title: `Track experiment: ${inputs.experimentName}/${inputs.runName}`,
      skill: {
        name: 'mlflow-experiment-tracker',
        context: {
          operation: 'log_run',
          experimentName: inputs.experimentName,
          runName: inputs.runName,
          parameters: inputs.parameters,
          metrics: inputs.metrics,
          modelPath: inputs.modelPath
        }
      },
      io: {
        inputJsonPath: `tasks/${taskCtx.effectId}/input.json`,
        outputJsonPath: `tasks/${taskCtx.effectId}/result.json`
      }
    };
  }
});

MCP Server Integration

Using mlflow-mcp Server

json
{
  "mcpServers": {
    "mlflow": {
      "command": "uvx",
      "args": ["mlflow-mcp"],
      "env": {
        "MLFLOW_TRACKING_URI": "http://localhost:5000"
      }
    }
  }
}

Available MCP Tools

  • mlflow_list_experiments - List all experiments
  • mlflow_search_runs - Search runs with filters
  • mlflow_get_run - Get run details
  • mlflow_log_metric - Log a metric
  • mlflow_log_param - Log a parameter
  • mlflow_list_artifacts - List run artifacts
  • mlflow_get_model_version - Get model version details

Best Practices

  1. Consistent Naming: Use descriptive experiment and run names
  2. Complete Logging: Log all hyperparameters, not just tuned ones
  3. Metric Granularity: Log metrics at appropriate intervals
  4. Artifact Organization: Use consistent artifact paths
  5. Model Documentation: Add descriptions to registered models
  6. Stage Management: Use proper staging workflow (None -> Staging -> Production)
