Which code should you use to configure the estimator?

You create a datastore named training_data that references a blob container in an Azure Storage account. The blob container contains a folder named csv_files in which multiple comma-separated values (CSV) files are stored.

You have a script named train.py in a local folder named ./script that you plan to run as an experiment using an estimator.

The script includes the following code to read data from the csv_files folder:

You have the following script.

You need to configure the estimator for the experiment so that the script can read the data from a data reference named data_ref that references the csv_files folder in the training_data datastore.

Answer: B

Explanation:

Besides passing the dataset through the inputs parameter in the estimator, you can also pass the dataset through script_params and get the data path (mounting point) in your training script via arguments. This way, you can keep your training script independent of azureml-sdk. In other words, you will be able use the same training script for local debugging and remote training on any cloud platform.

Example:

from azureml.train.sklearn import SKLearn

script_params = {

# mount the dataset on the remote compute and pass the mounted path as an argument to the training script

‘–data-folder’: mnist_ds.as_named_input(‘mnist’).as_mount(),

‘–regularization’: 0.5

}

est = SKLearn(source_directory=script_folder,

script_params=script_params,

compute_target=compute_target,

environment_definition=env,

entry_script=’train_mnist.py’)

# Run the experiment

run = experiment.submit(est)

run.wait_for_completion(show_output=True)
