When set DEBUG = True in setup.py, I get the following error:

when run "pip install -e",

Do I need to turn on the debug mode if I want the log information of spdlog::debug?

[xmfbit]

@Lenan22 To get the output of spdlog::debug, I add this method and set the logging level to debug:

void set_log_level(const std::string& level) {
    auto enum_level = spdlog::level::from_str(level);
    spdlog::set_level(enum_level);
}

// where you want to set logging level
set_log_level("debug");

@xmfbit Could you please tell me in which file you added these codes?

[xmfbit]

@Lenan22 You can add the definition of this method anywhere that the c++ syntax allows, and set the logging level to debug before where you want to start to print the log.

Actually, I add the method in pybind.cpp and bind it to python, which makes it possiable to set the level in python script.

// pybind.cpp

// author's code

void set_log_level(const std::string& level) {
    auto enum_level = spdlog::level::from_str(level);
    spdlog::set_level(enum_level);
}

// export to python
m.def("set_log_level", &set_log_level, py::arg("level"), "Set the logging level");
