Python 在windows上安装/升级tensorflow 2

在使用管理员权限打开

cmd

后，我运行了下面的命令。我现在有tensorflow

'1.15.0'

，我的python是

3.7.3

，我的pip是

PIP19.3.1，来自c:\users\nnn\anaconda3\lib\site packages\pip（Python3.7）

我是否应该升级

grpcio

我需要担心下面更新2中的警告吗

错误消息是

**ERROR: tensorboard 2.1.0 has requirement grpcio>=1.24.3, but you'll have grpcio 1.24.0 which is incompatible.**
