如何删除/刷新IPython / Jupyter notebook v4.0的可用内核？ [英] How do I delete/refresh available kernels for IPython/Jupyter notebook v4.0?

问题描述

我最近停止使用 macports ，因此我用于各种IPython内核的kernel.json文件已经过时了。我已重命名〜/ .ipython 并删除〜/ .jupyter 但启动的内核无法以<$ c开头$ c>找不到文件错误。

I've recently stopped using macports so the kernel.json files I had for various IPython kernels are out of date. I have renamed ~/.ipython and removed ~/.jupyter but kernels launched are failing to start with file not found errors.

更有说服力的是，当我运行 jupyter-kernelspec list 它仍然列出了我设置的所有旧内核。从哪里获取此信息以及我需要做些什么来刷新/删除其缓存？

More tellingly, when I run jupyter-kernelspec list it still lists all the old kernels I had set up. Where is it getting this information from and what do I need to do to refresh/remove its cache?

推荐答案

蛮力之后搜索，Jupyter在 / Users / $ {USER} / Library / Jupyter / kernels 中存储OS X的内核信息。此列表是从我的 .ipython / kernels 列表中复制的，因此重命名它没有区别。

After a brute force search, Jupyter stores kernel info for OS X in /Users/${USER}/Library/Jupyter/kernels. This list got copied across from my .ipython/kernels list hence renaming it made no difference.

删除 / Users / $ {USER} / Library / Jupyter / kernels 解决了这个问题。

这是我正在寻找的参考for： http://jupyter-client.readthedocs.org/en/latest/kernels.html# kernelspecs
