Other Attempts

• I converted the file to HTML using jupyter nbconverter with no problems
  • However, when I use pandoc to convert it to pdf it fails again:

$ pandoc 01-introduction.html -t pdf
Error producing PDF.

Try running pandoc with --pdf-engine=xelatex.

$ pandoc 01-introduction.html -o 01-introduction.pdf --pdf-engine=xelatex

Hi @baggiponte this one looks like an issue with nbconvert. What version are you using? If you just want to have a PDF, you can upgrade to nbconvert version 6 or newer (current version is 6.3.0) and use webpdf instead.

To update and install webpdf dependencies run:

pip install -U nbconvert[webpdf]
# you may (or may not) also need:
python3 -m nbconvert some_notebook.ipynb --to webpdf --allow-chromium-download

However, if you need LaTeX as intermediary, #42 brought proper support for LaTeX - please see Exporting to LaTeX in README.md; this is a very fresh addition so please let me know of any problems.

Edit: this will be available in version 0.2.0 to be released today.

This was included in release 0.2.0 now available on PyPI. Please let me know if either of the three solutions proposed:

1. updating nbconvert,
2. using webpdf
3. using LaTeX support

works well for you. Please feel welcome to add any further suggestions :)

Hi @baggiponte just checking if we can close this one. Did any of the proposed solution help?
