想用--vis命令可视化
搜到教程：

sudo apt-get install python-dev python-pygraphviz python-kiwi python-pygoocanvas python-gnome2 python-gnomedesktop python-rsvg
sudo apt-get install ipython

即可
然而提示E: Unable to locate package python-gnomedesktop
搜索得是包的名称不对
于是：

sudo apt-get install python-gnome2-desktop

然后E: Package 'python-gnome2-desktop' has no installation candidate
再查，安装python-gnome2-desktop-dev即可

结果失败emmm隔天再续
