Продолжайте работать с ошибкой, которая гласит: «Ошибка атрибута: объект« Нет типа »не имеет атрибута« текст ». Я понятия не имею, где проблема есть. Сделал изрядное количество исследований, но не видел ни одного сообщения, которые предоставили любую ясность по этому вопросу. Мысли?Ошибка Kivy: Ошибка атрибута: объект «Нет типа» не имеет атрибута «текст»

Я помню, получаю сообщение об ошибке так как интерфейс Kivy изменился с одной версии на другую; вероятно, функция, которая использовалась для возврата значения, больше не выполнялась. Здесь вы должны вставить все сообщение об ошибке, чтобы мы могли увидеть дамп стека и строку, в которой произошла ошибка. –
