jupyter 单元格自动重新运行插件
jupyter notebook 有没有可以实现更改变量，单元格自动重新运行功能的插件？
比如我在第n个单元格定义的变量x更新值后，后面使用到这个变量x的单元格都自动重新运行。
我记得见到过介绍类似功能的文章，但找不到了。
回答不易，求求您采纳点赞哦 感激不尽
是的，Jupyter Notebook有一个名为AutoReexec的插件，它可以帮助简化该过程。AutoReexec可以跟踪变量，如果检测到变量被更改，它会自动重新运行单元格，以便使用新的值。你只需要安装它，然后在想要重新运行的每个单元格中添加 #auto reexec 这行注释，就可以实现你的需求。
可以使用这个插件：jupyter-autotime
安装后在命令模式下，按 "ESC" 键
输入以下命令：%load_ext autotime

- 除此之外, 这篇博客: Jupyter lab（Jupyter notebook）中单元格图片的存储方式及导出（还原）方法（关键点：ipynb文件，图片base64编码）中的 代码单元格输出图片 部分也许能够解决你的问题, 你可以仔细阅读以下内容或者直接跳转源博客中阅读:
在代码单元格中输入以下内容并运行。
