Jupyter Notebook未与内核连接

标签： anaconda jupyter-notebook jupyter

这是2019年3月7日的问题，并且jupyter-notebook在2019年3月6日之前都可以正常工作。

今天正在显示

无法建立与笔记本服务器的连接。笔记本计算机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。

我尝试卸载龙卷风，但表明未安装龙卷风。

然后我安装了龙卷风5.1.1，虽然运行良好，但仍然存在问题。

我的Ubuntu是16.04 LTS，系统是Intel®Core™i5-4570 CPU @ 3.20GHz×4。

我昨天完成了sudo apt-get install update和sudo apt-get upgrade命令。我现在删除了昨天完成的更新，但是问题仍然存在。

出现在终端窗口中的错误是：

就我而言，我正在运行它。在我这方面缺乏了解：Tensorflow和Jupyter在Docker容器中运行，而该容器托管着Tornado 6，这会引起问题。我必须在该容器中而不是在普通台式机上用Tornado V5.1.1替换Tornado版本6（这是我第一次想知道是否根本没有安装Tornado）。我的错是我是Docker技术的新手-只是跟随了安装教程，后来才开始了解背景。

pip卸载龙卷风== 6.0.1 pip install tornado == 5.1.1
