Я пытаюсь предсказать цифру, используя пример keras, когда я тренировал свою модель, все в порядке, и точность тестовых данных очень хорошая, но когда я хочу предсказать цифру, у меня возникают проблемы с соответствиемразмеры, я попытался изменить размер цифры, но это все та же ошибка.
вот мой код: main.py :

train_label = pd.read_csv("C:/Users/GOT/Desktop/Arabic Handwritten Digits Dataset CSV/csvTrainLabel 60k x 1.csv").values
test_label = pd.read_csv("C:/Users/GOT/Desktop/Arabic Handwritten Digits Dataset CSV/csvTestLabel 10k x 1.csv").values

Ошибка:
ValueError: Error when checking input: expected conv2d_1_input to have shape (1, 28, 28) but got array with shape (28, 28, 1)
пожалуйста, помогите мне
