我刚刚从一个导入中得到以下错误，该导入在几个小时前可以正常工作，但一直在下降。

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-33-4c52b67c20bf> in <module>()
      1 import keras
----> 2 from keras.utils import to_categorical

ImportError: cannot import name 'to_categorical' from 'keras.utils' (/usr/local/lib/python3.7/dist-packages/keras/utils/__init__.py)

---------------------------------------------------------------------------
NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

To view examples of installing some common dependencies, click the

Keras 是否忙于更新以弃用此方法？
