我试图使用Keras将电影评论分类为各自的情感类别（积极或消极）。

import tensorflow as tf
from tensorflow import keras
import numpy as np

# Preprocessing the Data
X = np.array(X) / 255.0
y = keras.utils.to_categorical(y)

但是当我运行代码时，它给了我以下错误：

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

Python - 3.9.12
keras - 2.12.0
tensorflow - 2.12.0
