我在我的树莓派4中安装了jupyter笔记本，它可以工作。但在我安装了一些其他包后，jupyter笔记本无法打开ipynb文件(显示："500：无效的延续字节"(我删除了其他包，甚至重新安装了jupyter笔记型电脑，但错误仍然存在。我想可能有一些配置文件未配置，但我不知道是哪一个。如何修复此错误？谢谢
jupyter笔记本控制台中的错误消息：

我检查了ipynb文件，它可以使用python utf-8打开，但我不知道为什么不能在jupyter笔记本下打开。
谢谢弘。你的建议奏效了。我找到了configparser.py打开的文件。结果是"python3.7/site packages/tqdm-4.56.0.dist-info/entry_points.txt"；。我删除了文件，jupyter工作正常。
