answer is indeed D best_run, fitted_model = run.get_output() have a look at the documentation for configuring autoML using the python SDK https://docs.microsoft.com/en-us/azure/machine-learning/how-to-configure-auto-train

the answer is correct : 'D' If no input parameters are provided, get_output returns the best pipeline according to the primary metric. best_run, model = parent_run.get_output()

Given answer is correct: D. According https://docs.microsoft.com/en-us/python/api/azureml-train-automl-client/azureml.train.automl.run.automlrun?view=azure-ml-py: best_run, model = parent_run.get_output() The first item (index 0) of get_output() method list is the "best run" and the second (index 1) is the "model". Question is asking for model.

We can access the best run id and accuracy score with: automl_run_metrics = automl_run.get_metrics() https://github.com/elenacramer/Optimizing-an-ML-Pipeline-in-Azure Answer is B

B is worng! get_metrics() is a method of a run object, you need that first: best_run, fitted_model = automl_run.get_output() Then you can do best_run.get_metrics()

# Get the best run, and its metrics and arguments best_run = run.get_best_run_by_primary_metric() best_run_metrics = best_run.get_metrics() script_arguments = best_run.get_details() ['runDefinition']['arguments'] print('Best Run Id: ', best_run.id) print(' -AUC:', best_run_metrics['AUC']) print(' -Accuracy:', best_run_metrics['Accuracy']) print(' -Arguments:',script_arguments)

I think answer is B as get_metric get best model D is wrong as get_output()[1] no get_output()[0] Reference https://docs.microsoft.com/en-us/python/api/azureml-train-automl-client/azureml.train.automl.run.automlrun?view=azure-ml-py
