几个月来,我一直在我的根环境和其他一些环境中使用 jupyter notebook。上周升级到 jupyter notebook 5,直到昨天都运行良好。

昨天 - 电脑死机了。重新启动后,jupyter notebook 从 root 环境启动时会报错(2x):

(下面的一些信息替换为#)

[I 08:57:31.223 NotebookApp] Serving notebooks from local directory: #######

我尝试复制并粘贴上面提供的链接。它在下次启动时删除了一条错误消息,然后在尝试再次启动后删除了 2 条错误消息。

Jupyter notebook 在从不同的 conda 环境启动时可以工作。

关于如何让它再次在我的根环境中工作的任何想法?
