通过pip安装

sudo python3 -m pip install --upgrade pip --force-reinstall
sudo python3 -m pip install --user jupyter

sudo python2 -m pip install --upgrade pip --force-reinstall
sudo python2 -m pip install --user jupyter

我在安装的过程中，有一个报错如下

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.

解决方法是先手动卸载

sudo apt-get remove ipython

这样，安装完之后，运行jupyter notebook，就可以切换内核了
