[BUG] - Pdf export of jupyter notebooks is broken #2202

Open Adam-D-Lewis opened 6 months ago

Adam-D-Lewis commented 6 months ago

Describe the bug

image Exporting to pdf as shown in the image doesn't work.

Attempting to do so results in a new browser tab opening with the following message.

500 : Internal Server Error
The error was:

nbconvert failed: xelatex not found on PATH, if you have not installed xelatex you may need to do so. Find further instructions at https://nbconvert.readthedocs.io/en/latest/install.html#installing-tex.

As a workaround, I created a conda environment with jupyter and nbconvert-all and was able to convert via the command line with xvfb-run -a jupyter nbconvert ExampleExportNotebook.ipynb --to qtpdf after activating the environment.

Expected behavior

A pdf document generated and downloaded

This needs xelatex in the jupyterlab environment. This isn't something we probably want to put in the base Nebari image. In the past, latex related files could balloon the docker image size. we would need to look into it.

with the jhub-apps launcher in Nebari 2024.1.1 we will potentially soon have the ability to have named-servers with custom jupyterlab versions running from different conda environments. This owuld make this more feasible.
