Overview of this book

Over the past 10 years, deep learning has grown from being an academic research field to seeing wide-scale adoption across multiple industries. Deep learning models demonstrate excellent results on a wide range of practical tasks, underpinning emerging fields such as virtual assistants, autonomous driving, and robotics. In this book, you will learn about the practical aspects of designing, building, and optimizing deep learning workloads on Amazon SageMaker. The book also provides end-to-end implementation examples for popular deep-learning tasks, such as computer vision and natural language processing. You will begin by exploring key Amazon SageMaker capabilities in the context of deep learning. Then, you will explore in detail the theoretical and practical aspects of training and hosting your deep learning models on Amazon SageMaker. You will learn how to train and serve deep learning models using popular open-source frameworks and understand the hardware and software options available for you on Amazon SageMaker. The book also covers various optimizations technique to improve the performance and cost characteristics of your deep learning workloads. By the end of this book, you will be fluent in the software and hardware aspects of running deep learning workloads using Amazon SageMaker.

Debugging training jobs

To effectively monitor and debug DL training jobs, we need to have access to the following information:

  • Scalar values such as accuracy and loss, which we use to measure the quality of the training process
  • Tensor values such as weights, biases, and gradients, which represent the internal state of the model and its optimizers

Both TensorBoard and SageMaker Debugger allow you to collect tensors and scalars, so both can be used to debug the model and training processes. However, unlike TensorBoard, which is primarily used for training visualizations, SageMaker Debugger provides functionality to react to changes in model states in near-real time. For example, it allows us to stop training jobs earlier if training loss hasn’t decreased for a certain period.

In this section, we will dive deep into how to use TensorBoard and SageMaker Debugger. We will review the features of both solutions in detail and then develop practical experiences...
