我最近在Anaconda上的一些库遇到了一些问题,所以我重新安装了Anaconda,当我再次启动它时,Jupityr Notebook内核错误发现了以下文本:

当我启动并打开一个文件时,我得到这个错误。它拒绝运行代码,只是坐在那里有点死了。内核错误出现在几乎所有使用Jupyter notebook打开的文件中。

下面的解决方案对我很有效。您可以在虚拟环境中的命令提示符或Anaconda提示符中运行此代码。
详细的解释和说明请看这里。

此解决方案可能对Windows用户有帮助。
pip uninstall jupyter
1.转到
~\AppData\Roaming
(AppData是一个隐藏文件)并删除名为jupyter
和python
的文件夹(如果存在)。1.删除
~\.jupyter
、~\.ipython
。我使用的是Jupiter而不是Anaconda,这完美地解决了这个问题。不知道这是否适用于木星与水蟒。
我用了这个技巧,它为我工作,我也使用木星没有水蟒。

我也遇到了同样的问题,这个快速解决方案解决了我的问题
参考:Cannot uninstall requirement jupyter, not installed

遇到了同样的事情,但答案对我来说出奇的简单:我使用VSCode来执行一些生成图形的代码,虽然我指定了figsize(16,9),但在Jupyter Notebook中图形太大了。
在jupyter notebook里重新运行了一遍,一切正常。

我也有同样的问题。对我有用的是python -m ipykernel install --user --name(在此处插入您的env名称)。我现在可以在虚拟环境中打开Jupyter Notebook了。
