when running the code: diffopt.step(buff_losses)
the following problem occurs: RuntimeError: trying to differentiate twice a function that was markedwith @once_differentiable
but when setting track_higher_grads: bool = False, it runs correctly.
I want to know why this issue occurs. Thanks a lot for answering my question!

does this setting have any effect on the final result?
