我正在尝试安装 GPflow 以下
https://github.com/GPflow/GPflow/blob/master/README.md
我有 Ubuntu 16.04 LTS。
我成功安装了 tensorflow（我运行了一个简单的 python 脚本来测试它并且它有效）。
我从壳里跑
python setup.py develop
它给了我找不到文件 setup.py 的错误。所以我在本地文件夹中克隆了 GPflow git 存储库，然后从我执行的那个文件夹中
sudo python setup.py develop
（我需要使用 sudo 获得访问权限）。但我收到以下错误：
running develop
