python - 内核错误[无法启动内核]

问题描述

我是 jupyter 笔记本的新手。尝试引起新的嫉妒，但它只会产生内核错误。

我已尝试安装新内核，但与它无关。

解决方案

在你的日志上它说：

PermissionError: [Errno 13] Permission denied: 
'C:\\Users\\Hawarie\\AppData\\Roaming\\jupyter\\runtime\\kernel-be38d53a-3dcf-4aca-8395-
93f556611cac.json'

我假设您使用的是 Windows，您是否尝试过以管理员身份运行 Anaconda？
