如何在虚拟环境中放置自定义Jupyter内核? [英] How to place custom Jupyter kernels inside virtual environment?

问题描述

我有一个自定义的Jupyter内核，该内核使用使用matplotlib样式表的自定义IPython配置文件运行IPython.

I have a custom Jupyter kernel which runs IPython using a custom IPython profile which uses a matplotlib stylesheet.

我知道我可以正常成功地运行此命令:

I know to run this successfully normally I would put:

• 〜/.config/matplotlib/stylelib/

• The matplotlib stylesheet in ~/.config/matplotlib/stylelib/

〜/.ipython/

The IPython profile in ~/.ipython/

〜/.jupyter/kernels/my_kernel/

The kernel json in ~/.jupyter/kernels/my_kernel/

但是我是作为在virtualenv中运行的较大程序的一部分来执行此操作的，如果我将上面的内容放在上面，则计算机上运行的任何笔记本服务器都将能够看到自定义内核，即使它在外部运行也是如此静脉我不是这个意思，因为我不希望我的程序干扰计算机上的其他笔记本.

But I am doing this as part of larger program which runs in a virtualenv, and if I put the things as above then any notebook server running on the computer will be able to see the custom kernels, even if it is running outside the venv. I don't what this because I don't want my program to interfere with other notebooks on the computer.

我认为我需要做的是将这些东西放在venv内等效的某个位置上，但是我不知道它们应该去哪里.有人知道他们会去哪里吗?还是这仅仅是IPython/Jupiter无法/不会做的事情?

I think what I need to do is put the things above somewhere equivalent inside the venv but I can't figure out where they should go. Doe anyone know where they would go? Or is this just a thing IPython/Jupiter can't/won't do?

可能值得一提的是，例如在样式表的情况下，我不想仅将其放在程序的工作目录中(这是matplotlib提供的一个选项).

It's probably worth mentioning that in the case of the stylesheet for example I don't want to just put it in the working directory of my program (which is one option matplotlib offers).

推荐答案

您可以将kernelspecs放在VIRTUAL_ENV/share/jupyter/kernels/中，如果笔记本服务器在该env中运行，它们将变为可用.通常，<sys.prefix>/share/jupyter/kernels包含在查找内核规范的路径中.

You can put kernelspecs in VIRTUAL_ENV/share/jupyter/kernels/ and they will be made available if the notebook server is running in that env. In general, <sys.prefix>/share/jupyter/kernels is included in the path to look for kernelspecs.

您可以看到Jupyter将看到的各个位置，还可以看到jupyter --paths的输出:

You can see the various locations Jupyter will look, you can see the output of jupyter --paths:

$ jupyter --paths

$ jupyter --paths

config:
    /Users/you/.jupyter
    /Users/you/env/etc/jupyter
    /usr/local/etc/jupyter
    /etc/jupyter
data:
    /Users/you/Library/Jupyter
    /Users/you/env/share/jupyter
    /usr/local/share/jupyter
    /usr/share/jupyter
runtime:
    /Users/you/Library/Jupyter/runtime

内核规范被视为数据文件，并且可以找到在data:下列出的任何目录中，在kernels子目录中，例如/usr/local/share/jupyter/kernels.

Kernelspecs are considered data files, and will be found in any of those directories listed under data:, in a kernels subdirectory, e.g. /usr/local/share/jupyter/kernels.
