{"code":"SubscriptionNotRegistered","message":"Resource provider [N/A] isn't registered with Subscription [N/A]. Please see troubleshooting guide, available here: https://aka.ms/register-resource-provider","details":[],"additionalInfo":[]}
Please add 'Microsoft.Storage' in addition to 'Microsoft.MachineLearningServices' to your Subscription Resource Provider to resolve the issue.
1.Go to Azure Portal -> Select your Subscription -> Select Settings -> Select Resource Providers
check the Resource providers section to ensure 'Microsoft.MachineLearningServices' is registered.
If the provider is not registered, click the Register button and wait a few minutes for it to complete before attempting to deploy the model again.
2.Verify you have enough quota in your subscription for the resources you want to deploy, especially for virtual machine sizes.
3.Check that your account has the required permissions (at least Contributor role).
4.Try creating your Azure Machine Learning workspace and deploying your model in a different region.
please follow the instructions outlined in the exercise to complete the task.
We followed the instructions in the exercise to complete the task, and we did not encounter any issues on our end.
