Question

当我尝试打开我的.ipynb时，出现以下错误。同一目录中的其他笔记本也可以正常工作。

UI错误：

Close without saving?
File "cloner.ipynb" has unsaved changes, close without saving?Close without saving?
File "cloner.ipynb" has unsaved changes, close without saving?

Pip管理的软件包版本：

Name: jupyter
Version: 1.0.0
Summary: Jupyter metapackage. Install all the Jupyter components in one go.

Name: jupyterlab
Version: 2.0.1
Summary: The JupyterLab notebook server extension.

我尝试删除.ipynb_checkpoints文件夹，并在git中跟踪所有这些内容。

查看Jupyter日志，我发现由于nbsignatures.db数据库被锁定，该错误再次出现。 https://www.onooks.com/jupyter-fails-to-open-notebook-with-error-file-xx-has-unsaved-changes-close-without-saving/

Answer 1

看起来像git merge冲突，在我的文件中添加了非json行。

使用文本编辑器在cloner.ipynb源文件中进行查找：

<<<<<<< HEAD
  },
  {
   <CONTENTS OF MY CELL>
   ]
=======
>>>>>>> a23f8f8f9db0974b7de90c6e7ed8599fa04d53cc

删除了这些非json行，然后重新营业。

Answer 2

就我而言， jupytext 使我无法打开ipynb文件，因为我是使用其他编辑器而不是相应的python文件编辑ipynb文件的。

所以我对rm CORRESPONDING.py进行了攻击，然后就可以打开ipynb文件。

在JupyterLab中打开.ipynb时出错-“不保存即关闭？”
