The correct answer is A. Yes. This solution meets the goal. In this series, the correct solution properly uses run.log('unique_labels', len(label_values)) (or equivalent) to log the count of unique label column values as a named metric in the experiment run context, and then calls run.complete() after the…

Question

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You plan to use a Python script to run an Azure Machine Learning experiment. The script creates a reference to the experiment run context, loads data from a file, identifies the set of unique values for the label column, and completes the experiment run: from azureml.core import Run import pandas as pd run = Run.get_context() data = pd.read_csv('data.csv') label_vals = data['label'].unique() # Add code to record metrics here run.complete() The experiment must record the unique labels in the data as metrics for the run that can be reviewed later. You must add code to the script to record the unique label values as run metrics at the point indicated by the comment. Solution: Replace the comment with the following code: for label_val in label_vals: run.log('Label Values', label_val) Does the solution meet the goal?

Explanation

This solution meets the goal. In this series, the correct solution properly uses run.log('unique_labels', len(label_values)) (or equivalent) to log the count of unique label column values as a named metric in the experiment run context, and then calls run.complete() after the logging statement. This ensures the metric is captured and accessible in the Azure ML studio experiment view. The key elements are: obtaining the run context via Run.get_context(), computing the desired value, logging it with run.log(), and completing the run - all in the correct order.
