I have this code:
def _read_config(self):
    config = configparser.ConfigParser()
    config.sections()
   # I tried 
    path_main = os.path.dirname(os.path.realpath(__file__))
   # and this after create exec file with pyinstaller nothing changed
    path_main = os.getcwd() 
    print(path_main)
    file = os.path.join(path_main, "config.ini")
    print(file)
    config.read(file)
    return config
When I run the code in MacOS using the terminal with python gui.py, it prints this:
/Users/telos/Desktop/Telos-Monitor-Tool/client
/Users/telos/Desktop/Telos-Monitor-Tool/client/config.ini
But when I do pyinstaller --onefile --windowed gui.py, I receive 1 app file, when I run it I get this: 
/Users/telos
/Users/telos/config.ini
But the one file app and ``gui.py` is in the same directory.
So I have an error because the Python parser can't find config.ini.
As in comennt discasion advise me to use print(QtCore.QCoreApplication.applicationDirPath()) after recreating app, i have 2 file 1 gui.app, 2-nd gui.exec. gui.exec find config.ini fine and all work fine, but gui.app can't and send the error.
Any idea what is the problem?
