Jupyter笔记本500：内部服务器E

Question

我想学习如何使用笔记本电脑。到目前为止，我已经成功地下载并安装了它（使用pip），但打开它时遇到了问题。

我通过键入以下内容来打开它：

jupyter notebook

在我的终点站。它将在“我的浏览器”中打开，网址为：

http://localhost:8888/tree

我只得到一个大：

500 : Internal Server Error

信息。有人能告诉我出什么事了吗？

我的终端中的完整错误消息：

编辑

尝试按建议更新ipython时，生成以下错误消息：

Answer 1

也有类似的问题。用这个命令升级ipython后修复了这个问题

sudo pip install --upgrade "ipython[all]"

注意：确保使用双引号和[all]键入ipython

Answer 2

尝试先升级jupyter hub

pip install --upgrade jupyterhub


pip install --upgrade --user nbconvert

在windows 10上也为我工作过。

Answer 3

升级nbconvert包对我有效。pip install --upgrade --user nbconvert
