[英]Kernel error in spyder and jupyter notebook
I tried to use the Anaconda Navigator, but I'm getting this kernel error.我尝试使用 Anaconda Navigator,但出现此内核错误。
I had previously installed python 3.8 without Anaconda and had installed jupyter in it using pip, then I uninstalled it and installed Anaconda again.我之前安装了没有 Anaconda 的 python 3.8,并使用 pip 在其中安装了 jupyter,然后我卸载了它并再次安装了 Anaconda。
Since then this error arises whenever I try to compile a file and even in the jupyter notebook.从那时起,每当我尝试编译文件甚至在 jupyter notebook 中时都会出现此错误。
I tried : 1.) Reinstalling Anaconda 2.) Updating the setup tools我试过:1.) 重新安装 Anaconda 2.) 更新安装工具
None of these worked.这些都没有奏效。

The problem:问题:
I had previously installed jupyter using pip install, when I was working on python 3.8.我以前在使用 python 3.8 时使用 pip install 安装了 jupyter。 Now, I uninstalled python 3.8 and installed Anaconda instead.现在,我卸载了 python 3.8 并安装了 Anaconda。 This again reinstalled jupyter, thus was the cause of the problem.这再次重新安装了 jupyter,因此是问题的原因。
To resolve this, I uninstalled jupyter from AnacondaPrompt using conda uninstall jupyter
, and then reinstalled it, this time from conda install jupyter
.为了解决这个问题,我使用conda uninstall jupyter
uninstall jupyter 从 AnacondaPrompt conda uninstall jupyter
,然后重新安装了它,这次是从conda install jupyter
。 This resolved the kernel error.这解决了内核错误。
This is permission issue for that particular folder Set the environment path variables C:\\Users\\DELL\\AppData\\Roaming\\jupyter\\runtime这是该特定文件夹的权限问题 设置环境路径变量 C:\\Users\\DELL\\AppData\\Roaming\\jupyter\\runtime
give the permission and it will work给予许可,它会起作用
