可以尝试以下步骤进行解决:
!pip install tensorflow_hub
import tensorflow as tf
import tensorflow_hub as hub
if tf.__version__ < '1.14.0' or hub.__version__ < '0.4.0':
raise ImportError('Please upgrade your TensorFlow and TF-Hub installation to make full use of this notebook.')
!pip show tensorflow_hub
如果仍然无法解决问题,可以尝试重新安装Tensorflow和Tensorflow_hub或者重新启动Kernel。
