1. 首先在cmd 使用jupyter kernelspec list查看安装的内核和位置
2. 打开kernel.json文件，查看Python解释器的路径是否正确

Find the path using jupyter kernelspec list. Then you can navigate to that in your file manager and delete it, or do it from the terminal (rm -r path/to/directory on Unix; if you're on Windows, you'll have to look it up)
