nbconvert --to latex is adding \ to $ math

[guerreroda]

I have been experimenting with pymarkdown and other stuff in jupyter. It has been working fine but suddenly nbconvert began to have problems when exporting to PDF. Then, I uninstalled and re-installed with pip install nbconvert. Still does not work.

So I am trying to convert a simple file as a test:

x = 1
Markdown : While $ beta = 1 = x $ then x is {{x}}

This works just fine on notebook. First, I did jupyter nbconvert --to html try.ipynb. It looks great! But when I do jupyter nbconvert --to pdf try.ipynb I get some huge troubleshooting. cmd does not allow me to copy such a huge output, but in the notebook it looks like this:

500 : Internal Server Error
The error was:
nbconvert failed: PDF creating failed, captured latex output:

Afterwards I tried to jupyter nbconvert --to latex try.ipynb. It works but (just like the error says) it can't transform to pdf because it does this with the math:

While \$ \beta = 1.2 = x \$ then x is 1.2

How can i fix those extra \?

[mpacer]

Not sure whether that was intended to be in a markdown or a code cell…

But, you can try removing the space after the first $ and before the second. It might be a parsing issue.

[mpacer]

I also don't know why it wouldn't need you to have a \ before the beta… it shouldn't be automatically adding that since it doesn't know that it's a special character.

[guerreroda]

So dumb!! Thank you. Deleting the spaces works.
