使用nbconvert将jupyter笔记本转换为pdf时出现“缺少$插入"错误消息 [英] 'Missing $ inserted' error message when converting jupyter notebook to pdf with nbconvert

问题描述

当尝试使用以下命令将jupyter笔记本转换为pdf时:

When attempting to convert a jupyter notebook to pdf with the following command:

jupyter nbconvert --to pdf "Search and Other Content Finding Features.ipynb"

我收到一条错误消息:

! Missing $ inserted.
<inserted text>
                $
l.380 ... Other Content Finding Features_10_0.png}

?
! Emergency stop.
<inserted text>
                $
l.380 ... Other Content Finding Features_10_0.png}

我在此处找到了一些讨论.

I've found some discussion of what that is here.

但是，我在代码中找不到这些字符.可能还有其他原因吗?

However, I can't find these characters in my code. Could there be another cause?

推荐答案

在这种情况下，问题似乎是由我笔记本的文件名引起的.我不完全了解引起问题的原因，但是上面的错误消息包含对某些文本的引用:

The problem in this case seems to have been caused by my notebook's filename. I don't fully understand what caused the problem, but the error message above includes a reference to some text:

... Other Content Finding Features_10_0.png}.

该文本包含可能导致此错误的_.我认为发生的事情是，在转换脚本中的某个位置，如果文件名中有空格，则会生成一个带有下划线的文件，如图所示，然后触发该错误. (对我来说，这似乎有点像个错误，或者至少是一个弱点).

That text includes _ which can cause this error. I think what happens is that somewhere in the conversion script, if there are spaces in the filename, a file is generated with underscores as shown, and that then triggers the error. (This seems a little bit like a bug to me, or at least a weakness).

对我有用的解决方法只是更改jupyter笔记本的文件名，不包含任何空格.然后转换就顺利进行了.

The fix that worked for me was simply to change the jupyter notebook's filename not to include any spaces. Then the conversion ran without a hitch.
