在jupyter中选择python内核 [英] choose python kernel in jupyter

问题描述

我已经安装在Debian Jessie上：

Python2.7

Python3.5

我还通过 pip2 和 pip3

安装Jupyter

但是当我启动 jupyter-notebook 我只能使用python3作为内核！我使用Jupyter如何切换到pyhton2.7？

解决方案

我在数字海洋中使用了一台新的Debian 8.5机器。

以root身份，从apt安装 pip 和 jupyter ，和开发包也是。

  apt-get install python-py python-dev python3-pip python3-dev libzmq3 
 pip3安装jupyter 
  

使用 ipykernel添加Python2的内核， / code>模块。已经安装了Python3内核。

  pip install ipykernel 
 python2 -m ipykernel install 
  

当您运行 jupyter笔记本时，您应该同时拥有 Python 2 和 Python 3 列为可用内核。请注意，Tornado笔记本电脑服务器正在端口8888上提供HTTP，在许多机器上默认情况下不会打开。以下是

I have installed on Debian Jessie:

Python2.7

Python3.5

I have also installed Jupyter via pip2 and pip3

However when I launch jupyter-notebook I can only use python3 as kernel! How can I switch to pyhton2.7 when using Jupyter?

解决方案

I tried this with a fresh Debian 8.5 machine on Digital Ocean.

As root, install pip and jupyter from apt, and the development packages, too.

apt-get install python-pip python-dev python3-pip python3-dev libzmq3
pip3 install jupyter

Add the kernel for Python2 using the ipykernel module. The Python3 kernel is installed, already.

pip install ipykernel
python2 -m ipykernel install

When you run jupyter notebook, you should have both Python 2 and Python 3 listed as available kernels. Notice that the Tornado notebook server is serving HTTP on port 8888, which isn't opened by default on many machines. Here is a script that will run Jupyter for you, opening and closing port 8888 and running on a public IP.
