To the maintainer, sorry about the repeated run requests for formatting. Missed the `make style` outlined in contributing guidelines.

You can merge `main` into your branch to fix code formatting (we switched from isort+flake8 to ruff this week), and then run `make style` I believe that should be good. @mariosasko
