Почему возникает ошибка AttributeError?

Question

Задача следующая: есть два окна, одно основное, другое для открытия картинок.

Нужно чтобы после открытия изображения в одном окне, т.е. после нажатия на кнопку "Открыть", в другом окне это изображение появилось, для этого в этом окне есть label.

Возникает ошибка:

'Ui_Select_image' object has no attribute 'Osnovnoe_Okno'

Не изменяйте код, сгенерированный Qt Designer. Создайте другой класс, который наследуется от соответствующего виджета, и используйте созданный класс для его заполнения.
