Overview of this book

The book starts with an overview of the deep learning (DL) life cycle and the emerging Machine Learning Ops (MLOps) field, providing a clear picture of the four pillars of deep learning: data, model, code, and explainability and the role of MLflow in these areas. From there onward, it guides you step by step in understanding the concept of MLflow experiments and usage patterns, using MLflow as a unified framework to track DL data, code and pipelines, models, parameters, and metrics at scale. You’ll also tackle running DL pipelines in a distributed execution environment with reproducibility and provenance tracking, and tuning DL models through hyperparameter optimization (HPO) with Ray Tune, Optuna, and HyperBand. As you progress, you’ll learn how to build a multi-step DL inference pipeline with preprocessing and postprocessing steps, deploy a DL inference pipeline for production using Ray Serve and AWS SageMaker, and finally create a DL explanation as a service (EaaS) using the popular Shapley Additive Explanations (SHAP) toolbox. By the end of this book, you’ll have built the foundation and gained the hands-on experience you need to develop a DL pipeline solution from initial offline experimentation to final deployment and production, all within a reproducible and open source framework.

Summary

In this chapter, we have learned different ways to deploy an MLflow inference pipeline model for both batch inference and online real-time inference. We started with a brief survey on different model serving scenarios (batch, streaming, and on-device) and looked at three different categories of tools for MLflow model deployment (the MLflow built-in deployment tool, MLflow deployment plugins, and generic model inference serving frameworks that could work with the MLflow inference model). Then, we covered several local deployment scenarios, using the PySpark UDF function to do batch inference and MLflow local deployment for web service. Afterward, we learned how to use Ray Serve in conjunction with the mlflow-ray-serve plugin to deploy an MLflow Python inference pipeline model into a local Ray cluster. This opens doors to deploy to any cloud platform such as AWS, Azure ML, or GCP, as long as we can set up a Ray cluster in the cloud. Finally, we provided a complete end-to-end...
