c++调用python时出现错误

c++调用python时出现了以下错误：
Exception ignored in:
Traceback (most recent call last):
File "/usr/lib64/python3.6/threading.py", line 1289, in _shutdown
assert tlock.locked()

问题相关代码，请勿粘贴截图

以下是我的c++代码

void train()
{
         Py_Initialize();

        // 执行python脚本命令
        //PyRun_SimpleString("print('hello world')\n");
        PyRun_SimpleString("import sys");
        PyRun_SimpleString("sys.path.append('/usr/local/python3/lib/python3.6/site-packages')");
        PyRun_SimpleString("sys.path.append('/root/new_platform/cpp_DL/')"   
        PyObject* pModule = PyImport_ImportModule("cpython1");
        if(pModule == NULL){
            PyErr_Print();
            cout << "module not found" << endl;
        }
        PyObject* pFunc = PyObject_GetAttrString(pModule, "hello");
        if(!pFunc || !PyCallable_Check(pFunc)){
            cout << "function not found" << endl;
        }
        PyEval_CallObject(pFunc, nullptr);
        PyGILState_Release(state);
        Py_Finalize();
}

调用的python代码cpython

import argparse
def hello():
   print("parser")    
   parser = argparse.ArgumentParser(description='###train###')
   print("parser")
运行结果及报错内容

报错：
Exception ignored in:
Traceback (most recent call last):
File "/usr/lib64/python3.6/threading.py", line 1289, in _shutdown
assert tlock.locked()
希望有人能给予我解决方法
