重新加载tensorflow模块

Question

在预装有tensorflow-gpu==1.13.1的生产系统中，如果我需要运行tensorflow-gpu==2.1.0，则只能安装并重新加载该库，而无需重新启动系统，但是重新加载tensorflow库给我一个错误，如何我应该解决吗？

要在客户端计算机上重现该问题，

1.First

pip install tensorflow-gpu==1.13.1

2。然后运行以下代码

import tensorflow
print(tensorflow.__version__) 

它将打印

1.13.1

3。现在运行

pip install tensorflow-gpu==2.1.0 

4。如果运行以下代码（我在生产系统上运行以重新加载模块）

import tensorflow
from importlib import reload
tensorflow=reload(tensorflow)
print(tensorflow.__version__) 

您将收到reload引发的以下错误，我该如何解决？
