二、卡在 Running setup.py bdist_wheel for grpcio ... 处的解决办法
这是正在编译，只需要耐心等待即可！根据电脑配置不同，等待时间也不同，多则几个小时，少则几十分钟。
三、报错：Cannot uninstall ‘wrapt‘. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
只需要在命令行输入 pip install -U --ignore-installed wrapt enum34 simplejson netaddr -i https://pypi.mirrors.ustc.edu.cn/simple/ --default-timeout=1000000 即可，然后在重新下载安装tensorflow即可。
