在Anaconda当中安装tensorfolw遇到以下问题，解决方案：
一、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：
输入：pip install -U --ignore-installed wrapt enum34 simplejson netaddr
二、ERROR: tensorboard 1.14.0 has requirement setuptools>=41.0.0, but you’ll have setuptools 39.1.0 which is incompatible.
原因：
setuptools 版本太低
解决方法：
更新setuptools版本，输入： pip install --upgrade setuptools
