jupyter notebook中加入python3

jupyter notebook中只有python2没有python3怎么办?

没有python3的原因是jupyter notebook必须you内核 !!!

  • 查看jupyter notebook kernel:
jupyter kernelspec list

删除notebook kernel:

jupyter kernelspec remove kernelname

确保python3环境下安装了ipykernel:

pip3 install ipykernel

查看python3路径:

which python3

如果没有的话就安装python3:

sudo apt-get install python3-pip

升级:

sudo pip3 install --upgrade pip

然后输入命令:

pip3 install ipykernel
python3 -m ipykernel install

启动jupyter notebook:

jupyter notebook

现在jupyter notebook中就出现了python3。
