You have the following Azure subscriptions and Azure Machine Learning service workspaces:

• Subscription Name: 'Azure subscription 1', Subscription ID: 'sub-id-1', Workspace Name: 'ml-project', Resource Group: 'rg1'
• Subscription Name: 'Azure subscription 1', Subscription ID: 'sub-id-1', Workspace Name: 'ml-test', Resource Group: 'rg2'
• Subscription Name: 'Azure subscription 2', Subscription ID: 'sub-id-2', Workspace Name: 'ml-project', Resource Group: 'rg3'

You need to obtain a reference to the 'ml-project' workspace in the 'Azure subscription 1' subscription.

Solution: Run the following Python code:

from azureml.core import Workspace

ws = Workspace.get(name='ml-project',
                   subscription_id='sub-id-1',
                   resource_group='rg1')

Does the solution meet the goal?
