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 with the SageMaker data and model parallel libraries

These two libraries were introduced in late 2020, and significantly improve the performance of large-scale training jobs.

The SageMaker Distributed Data Parallel (DDP) library implements a very efficient distribution of computation on GPU clusters. It optimizes network communication by eliminating inter-GPU communication, maximizing the amount of time and resources they spend on training. You can learn more at the following link:

DDP is available for TensorFlow, PyTorch, and Hugging Face. The first two require minor modifications to the training code, but the last one doesn't. As DDP only makes sense for large, long-running training jobs, available instance sizes are ml.p3.16xlarge, ml.p3dn24dnxlarge, and ml.p4d.24xlarge.

The SageMaker Distributed Model Parallel (DMP) library solves a different...
