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.

Chapter 5: Running DL Pipelines in Different Environments

It is critical to have the flexibility of running a deep learning (DL) pipeline in different execution environments such as local or remote, on-premises, or in the cloud. This is because, during different stages of the DL development, there may be different constraints or preferences to either improve the velocity of the development or ensure security compliance. For example, it is desirable to do small-scale model experimentation in a local or laptop environment, while for a full hyperparameter tuning, we need to run the model on a cloud-hosted GPU cluster to get a quick turn-around time. Given the diverse execution environments in both hardware and software configurations, it used to be a challenge to achieve this kind of flexibility within a single framework. MLflow provides an easy-to-use framework to run DL pipelines at scale in different environments. We will learn how to do that in this chapter.
