was just talking to @john-science about the nbextensions. That's from back when we had an awesome dockerized jupyterhub instance of ARMI with all plugins. It added a few neat tools that some users liked. It's totally fine to remove it now since we don't know of anyone using them in jupyterhub at the moment.

Okay, so I opened the docs your PR generates: https://github.com/terrapower/armi/actions/runs/13082534763?pr=2050

Almost everything is working, and looks great.

But the "Gallery" section is broken:

There are no links to the generated pages. I downloaded another PRs recently generated docs and they did not have this problem.

@ntouran Could this be the dependency we dropped?

[john-science]

Do we know what happened to the Gallery yet? Was that the dependency we removed?

I haven't been researching this. I probably can't take a stab until next week given other priorities, though 😥

I can look into the gallery issue. I don't think it can be related to jupyter-contrib-nbextensions but it's something else.

last commit from me fixes it :)

Okay, I reviewed the output HTML and I think it looks good.
