anaconda - Jupyter Notebook 未与内核连接

问题描述

这是 2019 年 3 月 7 日的问题，并且 jupyter-notebook 工作正常，直到 2019 年 3 月 6 日。

今天它显示

无法建立到笔记本服务器的连接。笔记本电脑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。

我试图卸载龙卷风，但它表明龙卷风没有安装。

然后我安装了 tornado 5.1.1，它运行良好，但问题仍然存在。

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，但问题仍然存在。

终端窗口中出现的错误是：

解决方案

就我而言，我让它运行了。我缺乏理解：Tensorflow 和 Jupyter 在 Docker 容器中运行，而这个容器托管 Tornado 6，这会导致问题。我不得不在这个容器中而不是在普通桌面上用 Tornado V5.1.1 替换 tornado 版本 6（这是我第一次尝试，想知道我根本没有找到 Tornado 安装）。我的错，因为我是 Docker 技术的新手 - 只是按照安装教程，后来开始了解背景。

点卸载龙卷风==6.0.1 点安装龙卷风==5.1.1
