一覽

MLflow is an open-source platform for managing ML model lifecycles. You track experiments (metrics, parameters, artifacts), version models, deploy to production, and monitor performance. Mastery takes 4-6 weeks. Specialists earn 10-15% premium because they reduce model chaos, teams shipping models without tracking, deployment pain, and production failures. The skill sits between data science and DevOps.

什麼是 MLflow Production Tracking

MLflow is an open-source platform for managing the complete machine learning model lifecycle. It has four main components: Tracking (logging metrics and parameters during training), Projects (packaging code and dependencies), Model Registry (versioning and promoting models), and Serving (deploying models as REST APIs or batch predictions). A typical workflow: you train 20 models with different hyperparameters, MLflow logs all metrics and artifacts (model files, plots, reports). You compare experiments side-by-side, pick the best performer, register it as "production," and deploy it. In production, you log predictions and ground-truth labels, detect model drift, and trigger retraining when performance degrades.

❓ 常見問題

What's the difference between MLflow and other experiment trackers (Weights & Biases, Neptune)?
MLflow is open-source and self-hosted (free). W&B and Neptune are SaaS (paid). MLflow focuses on end-to-end model lifecycle (tracking, registry, serving, model evaluation). W&B is stronger in visualizations and collaboration. Choose MLflow if you want control and low cost; choose W&B if you want polish and cloud convenience.
How do I decide which model to deploy?
MLflow Model Registry lets you compare metrics (accuracy, F1, latency) across experiments. Pick the model with the best metric for your use case. Then A/B test in production: serve both models, measure real user satisfaction, deploy the winner.
Can MLflow handle large models (LLMs, computer vision)?
Yes, MLflow can track and serve any model. For very large models (100GB+), you might co-locate serving infrastructure (GPU clusters) rather than serving via MLflow's REST API. MLflow becomes a registry and metadata layer; serving happens via Torch/TF directly.
How do I monitor model drift in production?
Log prediction distributions and input feature distributions to MLflow. Compare production vs. training distributions. If they diverge (e.g., users start giving different input), model performance may degrade. Set up alerts for drift threshold violations.
Is MLflow suitable for CI/CD pipelines?
Yes. Integrate MLflow logging into your training pipeline. On each commit, train model, log to MLflow, compare against baseline. If metrics improve, promote to registry. Then deploy from registry to production. MLflow becomes the source of truth for model versions.
