具有Python 2和Python3内核的Jupyter笔记本 [英] Jupyter notebook with Python 2 and Python3 Kernel

问题描述

我想从Jupiter Notebook运行Python2和Python3内核.我正在使用Anaconda进行Python和Jupyter发行.

Lokeshs-MacBook-Air-2:~ lokeshagrawal$ conda --version
conda 4.5.12

Lokeshs-MacBook-Air-2:~ lokeshagrawal$ which python
/anaconda3/bin/python

Lokeshs-MacBook-Air-2:~ lokeshagrawal$ which jupyter notebook
/anaconda3/bin/jupyter

[![Lokeshs-MacBook-Air-2:~ lokeshagrawal$ python --version
Python 3.7.2

如下图所示，我只有一个选项可以从Jupyter启动Python3内核.我怎样才能同时拥有Python2和Python3?

解决方案

1. 确保您的点子版本大于9.0

$ python2 -m pip --version

2. 然后这样做

$ python2 -m pip install ipykernel OR python2 -m pip install ipykernel --user
$ python2 -m ipykernel install --user

3. 启动或重新启动Jupyter，您应该已完成.

I want to run Python2 as well as Python3 kernel from Jupiter notebook. I am using Anaconda for Python and Jupyter distribution.

Lokeshs-MacBook-Air-2:~ lokeshagrawal$ conda --version
conda 4.5.12

Lokeshs-MacBook-Air-2:~ lokeshagrawal$ which python
/anaconda3/bin/python

Lokeshs-MacBook-Air-2:~ lokeshagrawal$ which jupyter notebook
/anaconda3/bin/jupyter

[![Lokeshs-MacBook-Air-2:~ lokeshagrawal$ python --version
Python 3.7.2

As you can see in the image below, I only have an option to start Python3 kernel from Jupyter. How can I have Python2 and Python3 both?

解决方案

1. Make sure you have pip version greater than 9.0

$ python2 -m pip --version

2. Then do this

$ python2 -m pip install ipykernel OR python2 -m pip install ipykernel --user
$ python2 -m ipykernel install --user

3. Start or restart Jupyter and you should be done.

This solution is from the ipython docs by the way.
