ubuntu16下安装ipython

1.    sudo apt-get install ipython3

2.    sudo pip3 install jupyter 

        如有报错：Cannot uninstall 'ipython'. 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.

    执行sudo pip3 install jupyter --ignore-installed jupyter 即可

3.    输入ipython即可进入     quit退出    tab键自动补全
