如何在jupyter上将python 3.6内核与3.5一起添加 [英] How to add python 3.6 kernel alongside 3.5 on jupyter

问题描述

我正在尝试在Python 3.6上测试一些代码，但是我的系统默认python版本是python 3.5.我已经安装了python 3.6，并尝试按照jupyter文档安装新的python内核

I am trying to test some code on Python 3.6 but my system default python version is python 3.5 I have installed python 3.6 and have tried to follow the jupyter documentation to install a new python kernel

python3.6 -m pip install ipykernel
python3.6 -m ipykernel install --user

但是它没有用，因为它继续在菜单中显示单个内核:Python3

But it didn't work since it continues to show a single kernel in the menu: Python3

有人在同一jupyter安装中设法同时拥有3.5和3.6吗?

Has anyone managed to have both 3.5 and 3.6 in the same jupyter installation?

推荐答案

一个选项是创建一个可在jupyter笔记本中使用的内核.

one option is to create a kernel that you can use in jupyter notebook.

您可以在虚拟环境中执行此操作:

you can do this inside the virtual environment:

1. 打开您的终端，然后逐行输入以下内容

1. Open up your terminal and enter the following line by line

virtualenv -p python3.6 py_36_env

source py_36_env/bin/activate

pip install ipykernel

python -m ipykernel install --user --name=py_36_env

jupyter notebook

然后在jupyter笔记本中，您可以从上方显示的'New'下拉菜单中或给定的jupyter笔记本中的'Kernel'下拉菜单中选择3.6环境(py_36_env).

Then in jupyter notebook you can select the 3.6 environment (py_36_env) from the 'New' drop down menu shown above or from the 'Kernel' drop down menu within a given jupyter notebook.
