@martin-martin I'm currently struggling a little bit with the linter. My local ruff (same version as the CI/CD) is happy with the formatting:

Personally, I'd add the fastapi imports before the jinja2 and pydantic ones, but it seems ruff has a different opinion on that. Maybe you have a suggestion on how to fix the linter error?

@acsany it's usually a version mismatch between your local linting tools and the ones that the CI uses. The ones here on the materials repo are kind of old:

black[jupyter]==24.4.2
ruff==0.4.2

I've just set it up locally for me with the old versions, ran the lint check, and ruff did the fix for me that old man ruff expected (adding a newline between pydantic and fastapi. They needed some space to think...)

Great, a couple of small syncing changes and we're good to go 🚀
