  note: This error originates from a subprocess, and is likely not a problem with pip.

Try installing wheel in your Github action before installing curvlinops. See here.

Will try tomorrow.

Btw, nowadays I use pdm it's super nice---just a couple lines in pyproject.toml. Example here.

It's lightweight, unlike the heavy-handed poetry.

Solved by

python -m pip install --upgrade pip wheel packaging

[wiseodd]

The issue with this is that laplace-torch and other libraries depending on curvlinops will require to add python -m pip install --upgrade pip wheel packaging in their READMEs.

I think this is not ergonomic.

I will work on a PR to migrate to pdm.
