cmd安装 pip install tensorflow

1. 遇到报错
   ERROR: 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.
   解决办法：cmd输入 pip install -U --ignore-installed wrapt enum34 simplejson netaddr

2. 遇到报错
   ERROR: tensorboard 1.14.0 has requirement setuptools>=41.0.0, but you’ll have setuptools 39.1.0 which is incompatible.
   报错原因： setuptools 版本太低
   解决办法：更新setuptools版本
   cmd输入 pip install --upgrade setuptools
