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 remotely in the cloud with remote code in GitHub

The most reliable way to reproduce a DL pipeline is to point to a specific version of the project code in GitHub and then run it in the cloud without invoking any local resources. This way, we know the exact version of the code as well as using the same running environment defined in the project. Let's see how this works with our DL pipeline.

As a prerequisite and a reminder, the following three environment variables need to be set up before you issue the MLflow run command to complete this section of the learning:

export MLFLOW_TRACKING_URI=databricks
export DATABRICKS_TOKEN=[databricks_token]
export DATABRICKS_HOST='https://[your databricks host name/'

We already know how to set up these environment variables from the last section. There is potentially one more setup needed, which is to allow your Databricks server to access your GitHub repository if it is non-public (see the following GitHub Token...
