升级方法

使用pip uninstall之后再install的方法，也可以使用pip install --upgrade的方式。这里使用了uninstall -> install的方式

升级pip

升级命令：pip install --upgrade pip

安装tensorflow

命令：pip uninstall tensorflow
pip install tensorflow

错误信息与对应方法

setuptools版本过低

错误信息提示：
tensorboard 2.0.0 has requirement setuptools>=41.0.0, but you’ll have setuptools 39.1.0 which is incompatible.

• 原因
  setuptools版本过低，使用pip list可以确认到当前版本信息为：39.1.0

对应方法：升级setuptools即可（升至41.4.0）。
升级命令：pip install --upgrade setuptools

wrapt卸载错误信息提示

错误信息提示：
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.

• 原因
  pip 无法确认是否可以进行卸载，强制重新安装相关依赖与新版即可。

对应方法，执行如下命令升级wrapt扽吧版本
升级命令：pip install -U --ignore-installed wrapt enum34 simplejson netaddr

升级后版本确认

liumiaocn:tmp liumiao$ pip list |grep tensor
