PyBind11析构函数未调用？

Question

我有一个用PyBind11包装的c++类。问题是：当Python脚本结束时，c++destructor没有被自动调用。这会导致不整洁的退出，因为网络资源需要由析构函数释放。在

作为一种解决方法，有必要显式删除Python对象，但我不明白为什么！在

有人能解释一下这里出了什么问题，以及在对Python对象进行垃圾回收时如何自动调用destructor？在

Pybind11绑定代码：

py::class_<pcs::Listener>(m, "listener")
    .def(py::init<const py::object &, const std::string &, const std::string &, const std::string &, const std::string &, const std::set<std::string> &, const std::string & , const bool & , const bool & >(), R"pbdoc(
    Monitors network traffic.

    When a desired data source is detected a client instance is connected to consume the data stream.

    Reconstructs data on receipt, like a jigsaw.  Makes requests to fill any gaps.  Verifies the data as sequential.

    Data is output by callback to Python.  Using the method specified in the constructor, which must accept a string argument.

在Python中：
