我是python和jupyter笔记本的新用户。最近,我使用以下命令在anaconda提示符中安装了xbpch(https://xbpch.readthedocs.io/en/latest/index.html)软件包:conda install -c conda-forge xbpch 之后,每次我打开jupyter笔记本时,此回溯消息都会出现内核错误:

有人知道如何解决此问题吗?
答案 0 :(得分:0)
转到您的Jupyter目录(例如C:\Users\Admin\AppData\Roaming\jupyter\kernels\python3
)
然后制作kernel.json
(例如{{1})的副本,然后用记事本或JS IDE打开。
应该像这样:
kernel_old.json
如果您遇到这种情况,请使用Anaconda3 python更改路径:{
"argv": [
"C:\Users\Admin\AppData\Local\Programs\python\python37\python.exe",
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"display_name": "Python 3",
"language": "python"
}
然后再次启动jupyter。
