1.首先通过python3的pip3安装ipython3
sudo pip3 install ipython
2.安装python 内核
python2:
sudo pip2 install ipykernel
python3:
sudo pip3 install ipykernel
3.配置python内核
python 2:
sudo ipython2 kernel install --name python2
python 3:
sudo ipython3 kernel install --name python3
4.启动ipython notebook
sudo ipython notebook
注意事项：
由于安装ipython notebook 需要用到~/.cache/pip/http/ 和～/.cache/pip/ 这两个文件目录的root用户私有访问权限，故需要设置权限，否则安装提示失败，
操作命令如下：
sudo chown root ~/.cache/pip/http/
sudo chown root ~/.cache/pip/
