AutoMLRun Class

Represents an automated ML experiment run in Azure Machine Learning.

The AutoMLRun class can be used to manage a run, check run status, and retrieve run details once an AutoML run is submitted. For more information on working with experiment runs, see the Run class.

Initialize an AutoML run.

Constructor

AutoMLRun(experiment, run_id, **kwargs)

Parameters

Name	Description
experiment Required	Experiment The experiment associated with the run.
run_id Required	str The ID of the run.
experiment Required	Experiment The experiment associated with the run.
run_id Required	str The ID of the run.

Remarks

An AutoMLRun object is returned when you use the submit method of an experiment.

To retrieve a run that has already started, use the following code:


   from azureml.train.automl.run import AutoMLRun
   ws = Workspace.from_config()
   experiment = ws.experiments['my-experiment-name']
   automl_run = AutoMLRun(experiment, run_id = 'AutoML_9fe201fe-89fd-41cc-905f-2f41a5a98883')

Methods

cancel	Cancel an AutoML run. Return True if the AutoML run was canceled successfully.
cancel_iteration	Cancel a particular child run.
complete	Complete an AutoML Run.
continue_experiment	Continue an existing AutoML experiment.
fail	Fail an AutoML Run. Optionally set the Error property of the run with a message or exception passed to `error_details`.
get_best_child	Return the child run with the best score for this AutoML Run.
get_guardrails	Print and return detailed results from running Guardrail verification.
get_output	Return the run with the corresponding best pipeline that has already been tested. If no input parameters are provided, `get_output` returns the best pipeline according to the primary metric. Alternatively, you can use either the `iteration` or `metric` parameter to retrieve a particular iteration or the best run per provided metric, respectively.
get_run_sdk_dependencies	Get the SDK run dependencies for a given run.
pause	Return True if the AutoML run was paused successfully. This method is not implemented.
register_model	Register the model with AzureML ACI service.
resume	Return True if the AutoML run was resumed successfully. This method is not implemented.
retry	Return True if the AutoML run was retried successfully. This method is not implemented.
summary	Get a table containing a summary of algorithms attempted and their scores.
wait_for_completion	Wait for the completion of this run. Returns the status object after the wait.
