我从 anaconda 环境中打开了一个 jupyter notebook，但内核使用默认版本的 python 而不是此环境中定义的 python(我安装了所有 pthe 包)。
我怎样才能改变它？
(myEnv) okoub@my-mac:~/Desktop$jupyter notebook
[I 13:35:46.644 NotebookApp] The port 8888 is already in use, trying another port.

[I 13:35:46.675 NotebookApp] JupyterLab alpha preview extension loaded from /Users/okoub/anaconda3/lib/python3.6/site-packages/jupyterlab
我正在使用 MAC。
在环境中安装jupyter后:
source activate myEnv
conda install jupyter
jupyter notebook
我得到错误:

最佳答案
运行 conda install nb_conda_kernels，然后重新启动 jupyter。现在右上角应该有一个额外的选项来选择笔记本应该使用哪个 conda env 来执行代码。这是 IMO 最方便的解决方案，因为您可以在同一个项目中拥有多个笔记本，这些笔记本在各自的环境中运行，而不必一直source activate。
