html_ch export fails: jinja2.exceptions.TemplateNotFound: inliner #1590

Open lordgrenville opened 2 years ago

lordgrenville commented 2 years ago

I'm trying to export a notebook with collapsible headings, and have encountered a "missing template" issue. The template file is on my system, but I think the jinja Environment object is looking in the wrong place.

Here is the stack trace:

Possibly relevant versions: Python 3.10 (same failure occurs in another env with 3.8)

It looks like this user and this one are dealing with the same issue.

Following this answer, I solved the issue by downgrading to nbconvert 5.6.1. So my guess is something in nbconvert 6+ looks for a different path and can't find the templates.
