Learn Amazon SageMaker - Second Edition

By: Julien Simon

Overview of this book

Amazon SageMaker enables you to quickly build, train, and deploy machine learning models at scale without managing any infrastructure. It helps you focus on the machine learning problem at hand and deploy high-quality models by eliminating the heavy lifting typically involved in each step of the ML process. This second edition will help data scientists and ML developers to explore new features such as SageMaker Data Wrangler, Pipelines, Clarify, Feature Store, and much more. You'll start by learning how to use various capabilities of SageMaker as a single toolset to solve ML challenges and progress to cover features such as AutoML, built-in algorithms and frameworks, and writing your own code and algorithms to build ML models. The book will then show you how to integrate Amazon SageMaker with popular deep learning libraries, such as TensorFlow and PyTorch, to extend the capabilities of existing models. You'll also see how automating your workflows can help you get to production faster with minimum effort and at a lower cost. Finally, you'll explore SageMaker Debugger and SageMaker Model Monitor to detect quality issues in training and production. By the end of this Amazon book, you'll be able to use Amazon SageMaker on the full spectrum of ML workflows, from experimentation, training, and monitoring to scaling, deployment, and automation.

Training and deploying with your own code on MLflow

MLflow is an open source platform for machine learning (https://mlflow.org). It was initiated by Databricks (https://databricks.com), who also brought us Spark. MLflow has lots of features, including the ability to deploy Python-trained models on SageMaker.

This section is not intended to be an MLflow tutorial. You can find documentation and examples at https://www.mlflow.org/docs/latest/index.html.

Installing MLflow

On our local machine, let's set up a virtual environment for MLflow and install the required libraries. The following example was tested with MLflow 1.17:

  1. We first initialize a new virtual environment named mlflow-example. Then, we activate it:
    $ virtualenv mlflow-example
    $ source mlflow-example/bin/activate
  2. We install MLflow and the libraries required by our training script:
    $ pip install mlflow gunicorn pandas sklearn xgboost boto3
  3. Finally, we download the Direct Marketing dataset we already...
