Оценить модель в другом измерении данных

Question

У меня есть данные формы (37520, 32, 9) с пятью классами формы (37520, 5), я использую Conv1D для обучения модели, и до сих пор я могу тренировать данные. Но проблема в том, что мне нужно оценить его в другом измерении - (37520, 32, 4) (классы одинаковы), я получаю следующую ошибку:

    return accuracy

Возможно ли это сделать? Я тоже пытался использовать прогноз, но все равно получаю ошибку.
