error-001-azure-mgmt-resource-v25-modulenotfounderror-for-subscriptionclientpolicyclient

azure-mgmt-resource v25 ModuleNotFoundError for SubscriptionClient/PolicyClient

Diagnosis

azure-mgmt-resource v25.0.0 stripped submodules into standalone packages. Only resources remains.

Fix

SubscriptionClient from azure.mgmt.subscription (azure-mgmt-subscription). PolicyClient from azure.mgmt.resource.policy (azure-mgmt-resource-policy>=1.0.0b1). Tools register fine but fail at runtime.
