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.

Running locally with local code

Let's start with the first running scenario using the same Natural Language Processing (NLP) text sentiment classification example as the driving use case. You are advised to check out the following version of the source code from the GitHub location to follow along with the steps and learnings: https://github.com/PacktPublishing/Practical-Deep-Learning-at-Scale-with-MLFlow/tree/26119e984e52dadd04b99e6f7e95f8dda8b59238/chapter05. Note that this requires a specific Git hash committed version, as shown in the URL path. That means we are asking you to check out a specific committed version, not the main branch.

Let's start with the DL pipeline that downloads the review data to local storage as a first execution exercise. Once you check out this chapter's code, you can type the following command line to execute the DL pipeline's first step:

mlflow run . --experiment-name='dl_model_chapter05' -P pipeline_steps='download_data...
