module 'sys' has no attribute 'argv' when using python-tensorflow in Qt Creater

Question

Recently, I needed to use my tensorflow2 code which is coded by python in C++ with Qt. When I was testing the code, the error arose:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\programSoft\anaconda3\envs\newTensorflow2\lib\site-packages\tensorflow\__init__.py", line 49, in <module>
    from ._api.v2 import __internal__

    tpu_args = [arg for arg in sys.argv if arg.startswith('--tpu')]
AttributeError: module 'sys' has no attribute 'argv'

This is my C++ code:

void MainWindow::pythonTest()
{
    Py_SetPythonHome((wchar_t*)L"C:\\programSoft\\anaconda3\\envs\\newTensorflow2");
    Py_Initialize();
    if(!Py_IsInitialized()){
        qDebug()<<"python initialized failed";
        return;
    }

    PyRun_SimpleString("import tensorflow");
    Py_Finalize();
}
