TensorFlow安装出错

第一次报错

You are using pip version 19.0.3, however version 19.2.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

按照提示运行更新pip。

第二次报错

ERROR: tensorboard 1.14.0 has requirement setuptools>=41.0.0, but you'll have setuptools 38.4.0 which is incompatible.
运行pip3 install --upgrade setuptools，更新下setuptools。

第三次报错

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.
运行pip3 install -U --ignore-installed wrapt enum34 simplejson netaddr即可解决。

最后运行pip3 install tensorflow终于成功安装tensorflow。
花了一个早上，真是艰难。
