Jupyter一直运行良好，现在我的所有文件都无法运行，似乎都出现了相同的错误。卡在“内核启动”上，然后收到“连接失败”的消息。我看到其他人遇到了这个问题，尝试了几件事，但是到目前为止，没有任何东西可以解决问题。我不确定是什么原因引起的，在发生这种情况之前，我遇到了模块无法加载的问题，并一直试图解决此问题。我以为我撤消了所有可能导致那里问题的事情。
对于当前问题，我尝试过：降低龙卷风的等级，强制重新安装jupyter，更新jupyter，升级笔记本，重置jupyter笔记本的默认配置，安装提示工具包。
看着外壳，似乎json解码可能有问题，还有importerror和catch_config_error。它是这样的：
