SDK for Python (Boto3)

Amazon SageMaker Debugger built-in rules can be configured for a training job using the create_training_job() function of the Amazon Boto3 SageMaker AI client. You need to specify the right image URI in the RuleEvaluatorImage parameter, and the following examples walk you through how to set up the request body for the create_training_job() function.

The following code shows a complete example of how to configure Debugger for the create_training_job() request body and start a training job in us-west-2, assuming that a training script entry_point/train.py is prepared using TensorFlow. To find an end-to-end example notebook, see Profiling TensorFlow Multi GPU Multi Node Training Job with Amazon SageMaker Debugger (Boto3).

To configure a Debugger rule for debugging model parameters

The following code samples show how to configure a built-in VanishingGradient rule using this SageMaker API.

To enable Debugger to collect output tensors

Specify the Debugger hook configuration as follows:

DebugHookConfig={
    'S3OutputPath': 's3://<default-bucket>/<training-job-name>/debug-output',
    'CollectionConfigurations': [
        {
            'CollectionName': 'gradients',
            'CollectionParameters' : {
                'train.save_interval': '500',
                'eval.save_interval': '50'
            }
        }
    ]
}

This will make the training job save a tensor collection, gradients, every save_interval of 500 steps. To find available CollectionName values, see Debugger Built-in Collections in the SMDebug client library documentation. To find available CollectionParameters parameter keys and values, see the sagemaker.debugger.CollectionConfig class in the SageMaker Python SDK documentation.

To enable Debugger rules for debugging the output tensors

The following DebugRuleConfigurations API example shows how to run the built-in VanishingGradient rule on the saved gradients collection.

DebugRuleConfigurations=[
    {
        'RuleConfigurationName': 'VanishingGradient',
        'RuleEvaluatorImage': '895741380848.dkr.ecr.us-west-2.amazonaws.com/sagemaker-debugger-rules:latest',
        'RuleParameters': {
            'rule_to_invoke': 'VanishingGradient',
            'threshold': '20.0'
        }
    }
]

With a configuration like the one in this sample, Debugger starts a rule evaluation job for your training job using the VanishingGradient rule on the collection of gradients tensor.

Update Debugger Profiling Configuration Using the UpdateTrainingJob API Operation

Debugger profiling configuration can be updated while your training job is running by using the update_training_job() function of the Amazon Boto3 SageMaker AI client. Configure new ProfilerConfig and ProfilerRuleConfiguration objects, and specify the training job name to the TrainingJobName parameter.

ProfilerConfig={ 
    'DisableProfiler': boolean,
    'ProfilingIntervalInMilliseconds': number,
    'ProfilingParameters': { 
        'string' : 'string' 
    }
},
ProfilerRuleConfigurations=[ 
    { 
        'RuleConfigurationName': 'string',
        'RuleEvaluatorImage': 'string',
        'RuleParameters': { 
            'string' : 'string' 
        }
    }
],
TrainingJobName='your-training-job-name-YYYY-MM-DD-HH-MM-SS-SSS'

Add Debugger Custom Rule Configuration to the CreateTrainingJob API Operation

A custom rule can be configured for a training job using the DebugHookConfig and DebugRuleConfiguration objects using the Amazon Boto3 SageMaker AI client's create_training_job() function. The following code sample shows how to configure a custom ImproperActivation rule written with the smdebug library using this SageMaker API operation. This example assumes that you’ve written the custom rule in custom_rules.py file and uploaded it to an Amazon S3 bucket. The example provides pre-built Docker images that you can use to run your custom rules. These are listed at Amazon SageMaker Debugger image URIs for custom rule evaluators. You specify the URL registry address for the pre-built Docker image in the RuleEvaluatorImage parameter.

DebugHookConfig={
    'S3OutputPath': 's3://<default-bucket>/<training-job-name>/debug-output',
    'CollectionConfigurations': [
        {
            'CollectionName': 'relu_activations',
            'CollectionParameters': {
                'include_regex': 'relu',
                'save_interval': '500',
                'end_step': '5000'
            }
        }
    ]
},
DebugRulesConfigurations=[
    {
        'RuleConfigurationName': 'improper_activation_job',
        'RuleEvaluatorImage': '552407032007.dkr.ecr.ap-south-1.amazonaws.com/sagemaker-debugger-rule-evaluator:latest',
        'InstanceType': 'ml.c4.xlarge',
        'VolumeSizeInGB': 400,
        'RuleParameters': {
           'source_s3_uri': 's3://bucket/custom_rules.py',
           'rule_to_invoke': 'ImproperActivation',
           'collection_names': 'relu_activations'
        }
    }
]
