How to use the azure-mgmt-powerbiembedded.azure.mgmt.powerbiembedded.models.__dict__ function in azure-mgmt-powerbiembedded

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

        self.config = PowerBIEmbeddedManagementClientConfiguration(credentials, subscription_id, base_url)
        super(PowerBIEmbeddedManagementClient, 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 = '2016-01-29'
        self._serialize = Serializer(client_models)
        self._deserialize = Deserializer(client_models)

        self.workspace_collections = WorkspaceCollectionsOperations(
            self._client, self.config, self._serialize, self._deserialize)
        self.workspaces = WorkspacesOperations(
            self._client, self.config, self._serialize, self._deserialize)
