BRPC cause pybind embed hang

[chenzhengda]

Describe the bug (描述bug)

When I use brpc and pybind embed simultaneously and import numpy, the program gets stuck. However, it returns to normal once I remove the include for the brpc header file.

To Reproduce (复现方法)

#include <brpc/server.h>
#include <pybind11/embed.h>
#include <iostream>

namespace py = pybind11;

int main() {
    py::scoped_interpreter guard{};

    auto sys = py::module_::import("sys");
    std::cout << "Python version: " << sys.attr("version").cast<std::string>() << std::endl;

    // auto np = py::module_::import("numpy");
    // std::cout << "Numpy version: " << np.attr("__version__").cast<std::string>() << std::endl;

    return 0;
}

大概率是用法不对。
