Running Pybind11 on a Single Thread

问题

Is it possible to have pybind11 start a python interpreter on a single thread within C++? I have a class that

1. initializes the interpreter and
2. calls a function in a python script.

I would like to call this function on multiple threads that C++ creates.

#include "pybind11/pybind11.h" 
#include <iostream>
#include <thread>

namespace py = pybind11;

class callMyPythonFunctionFromCpp
{
    callMyPythonFunctionFromCpp() { m_module = py::module::import("mypython_script_file"); }

    void myfunc() // trying to call this function on multiple threads.
    { 
        py::object res = m_module.attr("myfunc");
    }

private:
    py::scoped_interpreter m_guard;
    py::module m_module;

};

void thread_function()
{
    callMyPythonFunctionFromCpp m;
    m.myfunc();
    std::cout << "thread function\n";
}

int main()
{
    std::thread t(&thread_function);
    // ...

    return 0;
}
