IPython Notebook错误:加载笔记本时出错

Question

在过去的几分钟内,我无法访问.ipynb以前使用Python3.4创建的任何文件.我带着这些文件进入子目录,输入

ipython3 notebook

当我打开"新"笔记本时,我收到以下错误:

Unexpected error while saving file: Untitled1.ipynb database disk image is malformed

我也打不开旧笔记本.我收到错误:

An unknown error occurred while loading this notebook. This version can load notebook formats v4 or earlier. See the server log for details.

它指出,在终端内

kernels (twice to skip confirmation).
[E 00:30:22.352 NotebookApp] Unhandled error in API request
    Traceback (most recent call last):
      File "/opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/traitlets/traitlets.py", line 460, in get
        value = obj._trait_values[self.name]
    KeyError: 'db'

我怎样才能解决这个问题？

Answer 1

这不会是每个人的问题，但我收到以下错误消息，因为磁盘实际上已满。

An unknown error occurred while loading this notebook. This version can load notebook formats v4 or earlier. See the server log for details.

Answer 2

搜索nbsignatures.db.它应该在这里:

~/.ipython/profile_default/security/nbsignatures.db

或者在这里:

 ~/Library/Jupyter/nbsignatures.db

该~代表你的home目录.

将此文件移动到临时目录.

重新启动您的IPython Notebook服务器.

Answer 3

删除 ~/.ipython/profile_default/history.sqlite

这对我有帮助。

Answer 4

由于我找不到其他答案中提到的任何文件,我找了另一个解决方案,发现这个对我有用:

我通过将〜/ .local/share/jupyter目录的所有权从root更改为user来解决了这个问题.
