安装TensorFlow报错
错误一：Cannot uninstall ‘wrapt’.
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.
强制更新： pip install -U --ignore-installed wrapt enum34 simplejson netaddr
错误二： setuptools 版本太低
ERROR: tensorboard 1.14.0 has requirement setuptools>=41.0.0, but you’ll have setuptools 39.1.0 which is incompatible.
强制更新： pip install --upgrade setuptools
