I have a JupyterLab notebook that I can export to Reveal.js slides just fine: it produces a nice html file that I am able to view in my browser. It looks like this:
Now I want to take that same notebook and start a live slideshow in JupyterLab, using RISE. But when I click on the Render notebook button (circled in the picture below), I get the following error:
I am thinking that there must be something very basic that I have done wrong, but I am afraid that I have no idea what it is (I use JupyterLab with Sagemath kernel frequently when I teach, but I am just starting to use Reveal.js and RISE, so I am probably missing a lot of what is going on here).
Would anyone please have any pointers to help me fix the issue?
Thank you very much!
