Вопрос:
У меня возникла проблема с попыткой открыть мой графический интерфейс ниже и получением ошибки, показанной ниже. Я сузил проблему до той части кода ниже, где я превращаю массив размером ~ 1,7 миллиметра, каждая запись которого содержит информацию о различной интенсивности пикселей rgb, в изображение размером 1300×1340 пикселей, а также в простой линейный рисунок.
Это ошибка, которую я получаю (это происходит, когда я устанавливаю для отображения фрейма значение True):

Exception detected while handling key input.звучит как проблема с обработчиком клавиатуры, а не проблема с Paint.
