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.

Automating with AWS CDK

AWS CDK is a multi-language SDK that lets you write code to define AWS infrastructure (https://github.com/aws/aws-cdk). Using the CDK CLI, you can then provision this infrastructure, using CloudFormation under the hood.

Installing the CDK

The CDK is natively implemented with Node.js, so please make sure that the npm tool is installed on your machine (https://www.npmjs.com/get-npm).

Installing the CDK is then as simple as this:

$ npm i -g aws-cdk
$ cdk --version
1.114.0 (build 7e41b6b)

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, and you could also use JavaScript, TypeScript, Java, and .NET. API documentation is available at https://docs.aws.amazon.com/cdk/api/latest/python/:

  1. First, we create a Python application named endpoint:
    $ mkdir cdk
    $ cd cdk
    $ cdk init --language python --app endpoint
  2. ...
