Я пытаюсь запустить этот код, но мне все еще мешает эта ошибка: OSError: Невозможно создать файл (невозможно открыть файл: name = '../working/best.hdf5', errno = 2, сообщение об ошибке= 'Нет такого файла или каталога', flags = 13, o_flags = 302)
Пожалуйста, если у кого-то была эта ошибка, и как ее решить, как я могу это исправить? Спасибо
