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.

Deploying using Ray Serve and MLflow deployment plugins

A more generic way to do deployment is to use a framework such as Ray Serve (https://docs.ray.io/en/latest/serve/index.html). Ray Serve has several advantages, such as DL model frameworks agnostics, native Python support, and supporting complex model composition inference patterns. Ray Serve supports all major DL frameworks and any arbitrary business logic. So, can we leverage both Ray Serve and MLflow to do model deployment and serve? The good news is that we can use the MLflow deployment plugins provided by Ray Serve to do this. Let's walk through how to use the mlflow-ray-serve plugin to do MLflow model deployment using Ray Serve (https://github.com/ray-project/mlflow-ray-serve). Before we begin, we need to install the mlflow-ray-serve package:

pip install mlflow-ray-serve

Then, we need to start a single node Ray cluster locally first using the following two commands:

ray start --head
serve start

This will...
