С ++, как мне открыть карту указателей на Python? Я получаю сообщение об ошибке "Нет участника с именем 'get_pytype'"

Я пытаюсь открыть вектор, содержащий указатели на объекты Address и карту, которая отображает указатель на объект Address на другой указатель на объект Address. Операторы == и! = Были реализованы в классе Address. Я видел этот пост , но до сих пор не совсем понимаю ответ из этого и документации . Должен ли я создать класс, унаследованный от map_indexing_suite? Я не смог найти хорошо документированный пример в Интернете, и копирование ответа не помогло (все та же ошибка).

Вот код: 

BOOST_PYTHON_MODULE(Utilities)
{
    // this compiles without any problem
    class_<std::vector<Address*>, std::vector<Address*>*>("AddressVector")
        .def(vector_indexing_suite<std::vector<Address*>>());
    // this does not compile
    class_<std::map<Address*, Address*>, std::map<Address*, Address*>*>("AddressMap")
        .def(map_indexing_suite<std::map<Address*, Address*>>());
}

Ошибка:
