Amazon SageMaker Debugger

Debug, monitor, and profile training jobs in real time, detect non-converging conditions, optimize resource utilization by eliminating bottlenecks, improve training time and reduce costs of your machine learning models using Amazon SageMaker Debugger.

New Debugger Features

SageMaker Debugger profiles and debugs your training jobs to improve the performance of machine learning models on compute resource utilization and model predictions. You can now achieve target accuracy faster using the following new Debugger features:

• Gain insights into your training jobs through SageMaker Studio Debugger insights dashboard and comprehensive reports autogenerated by Debugger. To learn more about the Debugger insights dashboard, see Debugger for Insights on Studio. To learn more about the reports, see SageMaker Debugger Profiling Report and SageMaker Debugger XGBoost Training Report.

• Use Debugger ProfilerRule for monitoring and profiling to automatically detect system bottlenecks in real time. To learn more, see Configure Debugger Built-in Rules and List of Debugger Built-in Rules.

• Use Debugger's built-in actions to receive notifications or automatically stop training jobs when Debugger Rule finds training issues in real time. To learn more, see Debugger Built-in Actions for Rules.

• Profile system resource usage and training operations, correlate system bottleneck issues with the training operations, and merge timelines with various profiler options. To learn more, see Configure Debugger Using Amazon SageMaker Python SDK and Analyze Data Using the SMDebug Client Library.

Debugger Features

Debugger provides the following features:

• SageMaker Studio Debugger dashboards in Studio Experiments and trials

• Comprehensive training reports autogenerated by Debugger

• Three types of built-in rules: monitoring system bottlenecks, profiling model framework operations, and debugging model parameters

• Debugger APIs in the SageMaker Python SDK to help configure SageMaker training jobs with monitoring, profiling, and debugging features

• Automated notifications and training job termination using Debugger built-in actions or creating customized actions in conjunction with Amazon CloudWatch Events and AWS Lambda

• The SMDebug client library to support model performance and parameter analysis

To see a list of SageMaker machine learning frameworks and algorithms that Debugger supports, see Supported Frameworks and Algorithms.

To learn more about the architecture of Debugger and how it works, see Debugger Architecture and Best Practices.

For Debugger tutorials and notebook examples, see Get Started with Debugger Tutorials.

Supported Frameworks and Algorithms

The following table shows SageMaker machine learning frameworks and algorithms supported by Debugger.

SageMaker frameworks and algorithms	Performance optimization		Model optimization
	Monitoring system bottlenecks	Profiling framework operations	Debugging model parameters
TensorFlow	All AWS Deep learning containers	AWS TensorFlow deep learning containers 2.3.1 or later	AWS TensorFlow deep learning containers 1.15.4 or later
PyTorch		AWS PyTorch deep learning containers 1.6.0 or later	AWS PyTorch deep learning containers 1.5.0 or later
MXNet		-	AWS MXNet deep learning containers 1.6.0 or later
XGBoost	1.0-1, 1.2-1	-	1.0-1, 1.2-1
SageMaker generic estimator	SageMaker Debugger built-in algorithms using image URIs Custom training containers (with the AWS deep learning container images, public Docker images, or your own Docker images)		Custom training containers (TensorFlow, PyTorch, MXNet, and XGBoost training scripts with a manual hook registration)

If the framework or algorithm that you want to train and debug is not listed in the table, go to AWS Discussion Forum and leave feedback on SageMaker Debugger.

Use Debugger with Custom Training Containers

Bring your training containers to SageMaker and gain insights into your training jobs using Debugger. Maximize your work efficiency by optimizing your model on EC2 instances using the aforementioned SageMaker Debugger features.

For more information about how to push your training container to Amazon Elastic Container Registry (ECR) and debug, see Use Debugger with Custom Training Containers.

Debugger Open Source GitHub Repositories

Debugger APIs are provided through the SageMaker Python SDK and designed to construct Debugger hook and rule configurations for the SageMaker CreateTrainingJob and DescribeTrainingJob API operations. The SMDebug client library provides tools to register hooks and access the training data through its trial feature, all through its flexible and powerful API operations. It supports the machine learning frameworks TensorFlow, PyTorch, MXNet, and XGBoost on Python 3.6 and later.

If you want to find direct resources of the Debugger and SMDebug API operations, see the following links:

• The Amazon SageMaker Python SDK documentation

• The Amazon SageMaker Debugger APIs

• The SMDebug open source client library

• The SMDebug PyPI

If you use the Java SDK to conduct SageMaker training jobs and want to configure Debugger APIs, see the following references:
