Jupyter 导入 Ipynb 文件错误：没有名为“mynotebook”的模块

Question

我需要导入不同的ipynb文件，所以我尝试了这个：

https://jupyter-notebook.readthedocs.io/en/stable/examples/Notebook/Importing%20Notebooks.html

但我没有找到名为“mynotebook”的模块。 （我什至尝试使用其他笔记本名称，这些名称肯定存在，但仍然无法正常工作）

你对我能做什么有什么想法吗？

import mynotebook

我只想导入另一个jupyter文件的代码

哇，我也面临这个问题。我创建了一个新环境，打开 jupyter 后，在我新安装的环境中找不到 nbformat，所以只需：

pip install nbformat
