я пытаюсь добавить пользовательский слой в мою модель, но у меня возникла эта нелогичная ошибка, что мне нужно изменить?если нужен код пользовательского слоя, дайте мне знать, что это будет значить для меня мир, если вы поможете мне понять, что я делаю неправильно. И как это исправить?

ValueError: An `initial_state` was passed that is not compatible with `cell.state_size`. Received `state_spec`=[InputSpec(shape=(None, 4, 4), ndim=3)]; however `cell.state_size` is (?, 4, 4) ```
