学习笔记《Ipython Notebook》

Hello, Ipython　Notebook

ipython notebook 无法正常启动

问题1. Connecting to 127.0.0.1:80… failed: Connection refused.”?

手动修改　firefox 代理

问题2. An unknown error occurred while loading this notebook. This version can load notebook formats v4 or earlier.

I solved this problem by changing the ownership of the ~/.local/share/jupyter　directory from root to user. I don’t know why this problem occurred, as it didn’t happen on my other systems, so perhaps it’s a bug and I will leave this here.
