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

        self.config = PolicyInsightsClientConfiguration(credentials, base_url)
        super(PolicyInsightsClient, self).__init__(self.config.credentials, self.config)

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