服务器启动但是当我打开一个笔记本,即使是一个空白的笔记本,内核死了并不断重启。我在arch-linux中使用python3.7。错误“RuntimeError:此事件循环已在运行”继续在循环中发生。

这可能是一个Arch Linux问题,已在他们的论坛上多次询问,例如here和bug report已经创建。它应该在python-ipykernel升级后解决,但我不知道这需要多长时间。
更新:它已在repo中更新,因此升级系统将修复它。
对我有用的临时hacky解决方案是使用pip作为用户升级它(因此它安装在〜/ .local而不是/ usr /),即:
pip install --user --upgrade ipykernel
这样,您不必降级任何软件包(这可能是一个更好的解决方案,但更烦人)。当Arch团队升级了软件包时,删除pip-version(pip uninstall ipykernel
)可能是个好主意。
