ValueError: ошибка при проверке ввода: ожидалось, что conv2d_1_input будет иметь 4 измерения, но получен массив с формой ⇐ Python

Когда я печатаю(inp_shape), я получаю (288, 512, 3). Однако я все еще получаю
ValueError: Error when checking input: expected conv2d_1_input to have 4
dimensions, but got array with shape (120, 1)

Я не понимаю, откуда взялась форма (120, 1).
