How to use the azure-mgmt-resource.azure.mgmt.resource.subscriptions.v2016_06_01.models function in azure-mgmt-resource

def __init__(
            self, credentials, base_url=None):

        self.config = SubscriptionClientConfiguration(credentials, base_url)
        super(SubscriptionClient, self).__init__(self.config.credentials, self.config)

        client_models = {k: v for k, v in models.__dict__.items() if isinstance(v, type)}
        self.api_version = '2016-06-01'
        self._serialize = Serializer(client_models)
        self._deserialize = Deserializer(client_models)

        self.operations = Operations(
            self._client, self.config, self._serialize, self._deserialize)
        self.subscriptions = SubscriptionsOperations(
            self._client, self.config, self._serialize, self._deserialize)
        self.tenants = TenantsOperations(
            self._client, self.config, self._serialize, self._deserialize)
