我的Jupyter笔记本电脑安装了python 2内核。我不明白为什么。我可能在安装的时候搞砸了。我已经安装了python 3。我怎么能把它加到木星上? 下面是默认的Jupyter使用python3 -m install Jupyter安装并在浏览器中使用Jupyter notebook打开的截图:

Here's a Windows/non command line method I found, which worked for me: Find the folder where the kernel files are stored (on my machine - C:\ProgramData\jupyter\kernels - note that ProgramData is a hidden folder), create a copy of the existing kernel's folder, change the name and edit the json file within to point to the new kernel's directory. In this json you can also edit the kernel name that is displayed in ipython (e.g. instead of just python 2 you can specify 2.7.9 if you need to further distinguish for some reason).

在Ubuntu 14.04上,我不得不使用之前答案的组合。

首先,安装pip3 安装python-pip3

然后用pip3安装jupyter Pip3安装jupyter

然后使用ipython3安装内核 Ipython3内核安装

sudo apt-get install python3-pip python3-dev
pip3 install -U jupyter

我很确定你要做的就是逃跑

Pip3安装jupyter

使用Python2获得ipython笔记本(在Windows7上) 用pip install -U Jupyter升级到Jupyter 安装Python3 使用pip3 install Jupyter再次安装Jupyter 使用ipython3 kernelspec install-self安装Python3内核 我终于有两个工作的玉米粒了。
