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 set up a local MLflow development environment that has full support for backend storage and artifact storage using MySQL and the MinIO object store. This will be very useful for us when we develop MLflow-supported DL models in this book. We started by presenting the open provenance tracking framework and asked model provenance tracking questions that are of interest. We worked on addressing the issues of auto-logging and successfully registered a trained model by loading a trained model from a logged model in MLflow for prediction using the mlflow.pytorch.load_model API. We also experimented on how to directly use MLflow's log_metrics, log_params, and log_model APIs without auto-logging, which gives us more control and flexibility over how we can log additional or customized metrics and parameters. We were able to answer many of the provenance questions by performing model provenance tracking, as well as by providing a couple of the questions that require...
