Great work. Do you know how I could fix this?

Hi there - I wonder if it could be related to this:

https://github.com/pytorch/pytorch/issues/37272

Maybe this is an issue related to a PyTorch version?

You are right https://discuss.pytorch.org/t/runtimeerror-could-not-run-aten-conj-out-with-arguments-from-the-cudatensorid-backend-aten-conj-out-is-only-available-for-these-backends-cputensorid-variabletensorid/97070
