Jupyter无法识别Python Mac OSX（内核错误）

Question

我用Anaconda安装了python 3.6，但是在启动jupyter笔记本后我无法使用python。

当我启动一个新笔记本时，我在页面顶部看到“内核错误”，其中包含以下行：

 Traceback (most recent call last):

我想最后一行是解决这个问题的关键，但我也没有找到任何相关的解决方案。

任何想法？

我终于找到了一个解决方法：

export PATH=~/anaconda3/bin:$PATH
conda create -n py33 python=3.6 anaconda
source activate py33
python -m ipykernel install --user
