我最近升级了我计算机上的每个 Python 库，但我无法从 Jupyter 的文件菜单转换我的笔记本。我收到消息：

500 : Internal Server Error
The error was:
nbconvert failed: '.\cumulative chart (for ANE17 poster).ipynb' exists but is not a directory

我可以通过命令行进行转换，实际上这是可行的：

[NbConvertApp] Converting notebook .\cumulative chart (for ANE17 poster).ipynb to pdf
[NbConvertApp] Support files will be in cumulative chart (for ANE17 poster)_files\
[NbConvertApp] Making directory .\cumulative chart (for ANE17 poster)_files

[NbConvertApp] WARNING | b had problems, most likely because there were no citations

但是，Jupyter 和/或 nbconvert 和/或 Pandoc/MiKTex 库发生了什么？谢谢您的意见

实际上，我在重新安装 Jupyter 后遇到了同样的问题。根据this page，这是从5.2开始的最新版本notebook包中的一个错误，应该在以后的版本中修复。目前，解决方案只是降级notebook软件包，例如：

pip install -U "notebook<5.2"

至少它对我有用。
