Learn Amazon SageMaker

By: Julien Simon

Overview of this book

Amazon SageMaker enables you to quickly build, train, and deploy machine learning (ML) models at scale, without managing any infrastructure. It helps you focus on the ML problem at hand and deploy high-quality models by removing the heavy lifting typically involved in each step of the ML process. This book is a comprehensive guide for data scientists and ML developers who want to learn the ins and outs of Amazon SageMaker. You’ll understand how to use various modules of SageMaker as a single toolset to solve the challenges faced in ML. As you progress, you’ll cover features such as AutoML, built-in algorithms and frameworks, and the option for writing your own code and algorithms to build ML models. Later, the book will show you how to integrate Amazon SageMaker with popular deep learning libraries such as TensorFlow and PyTorch to increase the capabilities of existing models. You’ll also learn to get the models to production faster with minimum effort and at a lower cost. Finally, you’ll explore how to use Amazon SageMaker Debugger to analyze, detect, and highlight problems to understand the current model state and improve model accuracy. 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.

Automating with the AWS Cloud Development Kit

The Cloud Development Kit (CDK) is a multi-language SDK that lets you write code to define AWS infrastructure ( Using the CDK CLI, you can then provision this infrastructure, using CloudFormation under the hood.

Installing CDK

CDK is natively implemented with Node.js, so please make sure that the npm tool is installed on your machine (

Installing CDK is then as simple as this:

$ npm i -g aws-cdk $ cdk --version 1.55.0 (build 48ccf09)

Let's create a CDK application and deploy an endpoint.

Creating a CDK application

We'll deploy the same model that we deployed with CloudFormation. I'll use Python, but you could also use JavaScript, TypeScript, Java, and .NET. The API documentation is available at Let's begin:

  1. We create a Python application named endpoint:
    $ mkdir cdk $ cd cdk ...
