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.

Implementing a custom MLflow Python model

Let's first describe the steps to implement a custom MLflow Python model without any extra preprocessing and postprocessing logic:

  1. First, make sure we have a trained DL model that's ready to be used for inference purposes. For the sake of learning in this chapter, we include the training pipeline MLproject in this chapter, so that we can easily produce a fine-tuned DL model. To run the training pipeline, make sure you have the virtual environment set up for this chapter by following the README file in this chapter's GitHub repository and set up the environment variables accordingly (https://github.com/PacktPublishing/Practical-Deep-Learning-at-Scale-with-MLFlow/blob/main/chapter07/README.md). Then, in the command line, run the following command to generate a fine-tuned model in the local MLflow tracking server:
    mlflow run . --experiment-name dl_model_chapter07 -P pipeline_steps=download_data,fine_tuning_model
