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.

Examining model artifacts and exporting models

A model artifact contains one or several files that are produced by a training job and that are required for model deployment. The number and nature of these files depend on the algorithm that was trained. As we've seen many times, the model artifact is stored as a model.tar.gz file, at the S3 output location defined in the estimator.

Let's look at different examples, where we reuse artifacts from the jobs we previously trained.

Examining and exporting built-in models

Almost all built-in algorithms are implemented with Apache MXNet, and their artifacts reflect this. For more information on MXNet, please visit https://mxnet.apache.org/.

Let's see how we can load these models directly. Another option would be to use Multi Model Server (MMS) (https://github.com/awslabs/multi-model-server), but we'll proceed as follows:

  1. Let's start from the artifact for the Linear Learner model we trained in...
