ValueError: неверные данные маршалинга (код неизвестного типа)

Моя операционная система - Ubuntu.

И я получил это сообщение об ошибке, когда запускал свою модель keras.

Я искал в Google некоторые решения, но они не работают. Например, я пробовал упомянутые решения в этом посте: Как исправить ошибку Python ValueError: неверные данные маршалинга?

Using TensorFlow backend.
