Кодек «charmap» не может кодировать символы в позициях 18-37: символ сопоставляется с ошибкой <undefined>

Я пытаюсь подключить модель ml с помощью django. Здесь я загрузил модель и необходимые codeировщики.

Для codeа выше, ниже приведен вывод. Обратите внимание, что я включил часть вывода в консоль.

Для переменной predicted_outcome он выводит

Как решить эту проблему?
