Selfish curiosity - is this action meant to be run on GPUs? Or is it just trying to get at something at the API level that doesn't need hardware?

[lilyminium]

Yes, I think this needs GPUs to run, so this CI might not go anywhere since GitHub doesn't have widely available GPU runners yet -- this test might have to be for local testing only. Although I'm having difficulty reproducing this on the same machine I saw it on in the first place...

[lilyminium]

I can't seem to trigger this with a trimmed down example, although I'm still seeing the error if I try to run a production fit and removing num_workers does fix it in that instance. In general allowing kwargs to set these options seems like a good idea, though.
