You submit the experiment with the following code:

You need to create Python code that returns the best model that is generated by the automated machine learning task.
Which code segment should you use?

  • A. best_model = automl_run.get_details()
  • B. best_model = automl_run.get_metrics()
  • C. best_model = automl_run.get_file_names()[1]

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()

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
