What is the key for check-only dependencies?

Missed this message. Sorry!

I don't recall offhand.
I'll try and figure it out in a moment.

Depends on how you solved it.
If you added torch to checkInputs, maybe add it to the default overrides in poetry2nix.

I don't think you need to worry if you ultimately just disabled the tests for clu.

I don't see a way that this would lead you to nixpkgs in either case though (you're modifying a derivation that poetry2nix creates, not one from nixpkgs).\

I'm unlikely to have time to look into supporting the new pyproject.toml syntax any time soon (see that as a call to action).

Patches very welcome.
