PDF conversion error: No filter named 'convert_explicitly_relative_paths'

[Kevin-Mattheus-Moerman]

When I try to export a notebook to a PDF (PDF via Latex option) file I get: nbconvert failed: No filter named 'convert_explicitly_relative_paths'.

I use Jupyter for teaching and I usually also share the PDF with students. Any help to address the above would be appreciated. Thanks.

More details below.

The error sounds Tex/Latex related, but I do have all dependencies installed (e.g. pandoc texlive-xetex texlive-fonts-recommended texlive-plain-generic).

I am running a Julia Jupyter notebook but I get the same for a Python on Octave kernel.

For completeness, the full output when I try it in the terminal instead using jupyter nbconvert --to PDF Untitled1.ipynb, is:

Still stuck on this issue. Any help appreciated.

Hello! Sorry about the problem you have been having. convert_explicitly_relative_paths was added to nbconvert and the default LaTeX document template in v7.5.0 (see this for details). I am not sure how you ended up with the updated template and an outdated nbconvert, but I imagine this problem can be avoided by either:

• Updating nbconvert
• Removing the function from the template, the path to which is in the error log you posted.

Let me know if there are any further problems.

@tuncbkose thanks. Upgrading nbconvert solved the PDF export issue relating to convert_explicitly_relative_paths. I think I had a funny set-up because I tried to get both RISE presentations and interactive Julia content to work. No luck on those. I think I have to wait for RISE to be compatible with the newer notebook formats.

Thanks for the above anyway. I'll close this one now.
