debuggerHook is not saving tensors in s3

Describe the bug

Exception during rule evaluation: Customer Error: No debugging data was saved by the training job. Check that the debugger hook was configured correctly before starting the training job. Exception: Training job has ended. All the collection files could not be loaded | Exception during rule evaluation: Customer Error: No debugging data was saved by the training job.

                      "TrialComponentDisplayName": "Training",
                  })

Expected behavior I should get tensors saved in s3

@tiru1930 Sorry that you run into this problem.

• Is the Iam role you used has the proper permission setup to access the debug S3 bucket s3://{bucket}/{prefix}/debug
• Could you show me the entire training job if possible?
• How long does the training job run? Did it successfully generated a model?

[tiru1930]

Is the Iam role you used has the proper permission setup to access the debug S3 bucket s3://{bucket}/{prefix}/debug Yes, Could you show me the entire training job if possible? do you mean logs?

How long does the training job run? Did it successfully generated a model? it ran for few mins, and yes, it generated model and stored in s3, i was able to deploy

[icywang86rui]

Could you show me the entire training job if possible? do you mean logs?

Yes. sorry for the delay. are you still experiencing this problem?

Hi, I'm having this issue as well. The model will train successfully and I can deploy it to an endpoint, but the "training_job_end.ts" file is empty.

Here's the estimator object I'm using:

xgb = sagemaker.estimator.Estimator(
    container,
    role,
    instance_count=1,
    instance_type='ml.m4.xlarge',
    output_path=s3_xgb_output_location,
    sagemaker_session=sagemaker_session,
    hyperparameters=hyperparameters,
    debugger_hook_config=DebuggerHookConfig(
        s3_output_path=s3_xgb_output_location,
        collection_configs=[
            CollectionConfig(name="metrics", parameters={"save_interval": str(save_interval)}),
            CollectionConfig(
                name="feature_importance", parameters={"save_interval": str(save_interval)}
            ),
            CollectionConfig(name="full_shap", parameters={"save_interval": str(save_interval)}),
            CollectionConfig(name="average_shap", parameters={"save_interval": str(save_interval)}),
        ],
    ),
    rules=[
        Rule.sagemaker(
            rule_configs.loss_not_decreasing(),
            rule_parameters={
                "collection_names": "metrics",
                "num_steps": str(save_interval * 2),
            },
        ),
    ],                          
)

Then, I try to get the smdebug trial artifacts:

s3_output_path = xgb.latest_job_debugger_artifacts_path()
trial = smd.create_trial(s3_output_path)
