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 manage an Azure Machine Learning workspace. The Python script named script.py reads an argument named training_data. The training_data argument specifies the path to the training data in a file named dataset1.csv. You plan to run the script.py Python script as a command job that trains a machine learning model. You need to provide the command to pass the path for the dataset as a parameter value when you submit the script as a training job. Solution: python train.py --training_data training_data Does the solution meet the goal?

Why each option

The proposed solution does not correctly pass the training_data path argument to the command job script in Azure ML SDK v2.

AYes

The proposed solution does not correctly wire the data asset path to the training_data argument, so it does not meet the stated goal and cannot be selected as correct.

BNoCorrect

In Azure ML SDK v2, passing a data path to a command job requires defining an Input() object with the correct asset type (such as uri_file) and referencing it in the command string using the ${{inputs.<name>}} placeholder syntax. The proposed solution does not fulfill this requirement correctly, so the script cannot receive the training_data path as intended.
