Неопределенный символ: pyobject_ selficiter при использовании cpython c api [дубликат] ⇐ C++

Я хочу использовать CPYTHON C API, но все же получил это < /p>

Я пробовал различные методы и даже спросил несколько инструментов ИИ, но все еще не могу решить это, и, похоже, я должен отказаться от вызова кодов Python из моей среды C ++.  Есть идеи?MyNode::MyNode(const rclcpp::NodeOptions& options)
: BaseNode("perception_node", options), time_stamp_(0), tracking_module_(nullptr), tracking_function_(nullptr) {

// Initialize Python interpreter
if (!Py_IsInitialized()) {
Py_Initialize();
// Initialize numpy by importing it
PyRun_SimpleString("import numpy");
}

// Import tracking module
PyObject* sys_path = PySys_GetObject("path");
PyObject* path_str = PyUnicode_FromString("/workspaces/perception/LSTM_Tracking/Tracking");
PyList_Append(sys_path, path_str);
Py_DECREF(path_str);

tracking_module_ = PyImport_ImportModule("Track_infer");
if (!tracking_module_) {
RCLCPP_ERROR(this->get_logger(), "Failed to import tracking module");
PyErr_Print();
} else {
tracking_function_ = PyObject_GetAttrString(tracking_module_, "return_tracking_id");
if (!tracking_function_) {
RCLCPP_ERROR(this->get_logger(), "Failed to get tracking function");
PyErr_Print();
}
}

Это конструктор MyNode, у меня проблемы даже за запуском
