Бэкэнд был * изначально * установлен в 'TkAgg' и gunicorn: ошибка: нераспознанные аргументы: --bind во время работы колбы с использованием gunicorn

Question

Ниже я получаю ошибку, которая повторяется до выхода из программы, используя ctrl-c.

Я использую следующую команду и скрипт wsgi.

Команда : gunicorn --bind 0.0.0.0:5000 wsgi:app

wsgi.py

from app import application

if __name__ == "__main__":
    application.run()

Повторный журнал ошибок:

Важная строка ошибки

`gunicorn: error: unrecognized arguments: --bind 0.0.0.0:5000 wsgi:app

Я не могу понять, что происходит не так. Кто-нибудь может мне помочь с этим. Благодарю.

PS: Вы видите, что The backend was *originally* set to 'TkAgg' by the following code: повторяется дважды. Это повторяется, пока я не остановлю приложение колбы.
