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 local code remotely in the cloud

In previous chapters, we ran all our code in a local laptop environment, and limited our DL fine-tuning step to only three epochs due to the limited power of a laptop. This serves the purpose of getting the code running and testing quickly in a local environment but does not serve to build an actual high-performance DL model. We really need to run the fine-tuning step in a remote GPU cluster. Ideally, we should only change some configuration and still issue the MLflow run command line in a local laptop console, but the actual pipeline will be submitted to a remote cluster in the cloud. Let's see how we can do this for our DL pipeline.

Let's start with submitting code to run in a Databricks server. There are three prerequisites:
