jupyter笔记本保持与内核的连接 [英] jupyter notebook keeps CONNECTING TO KERNEL

问题描述

Jupyter笔记本一直在说Connecting to kernel，直到永远不会弹出错误，

The Jupyter notebook keeps saying Connecting to kernel, which never reaches finally popping an error,

无法建立与笔记本服务器的连接.笔记本将继续 尝试重新连接.检查您的网络连接或笔记本服务器 配置.

A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration.

因此，命令行上的星号将永远保留.

So the asterisk on the command line stays forever.

奇怪的是，终端上的iPython可以正常运行.

The strange part is, iPython on terminal works FINE.

这是我尝试过的:

1. 将浏览器从Chrome更改为Firefox
2. 将端口号更改为"8888"以外的其他名称
3. 卸载Jupyter并重新安装

有人遇到类似问题吗?

推荐答案

我遇到了类似的问题.它是由龙卷风包装引起的，我不得不对其进行降级.

I had a similar issue. It was caused by the tornado-package and I had to downgrade it.

sudo pip3 uninstall tornado
sudo pip3 install tornado==5.1.1
