feat: return value of parallel_model is unnatural about xmunmt HOT 2 CLOSED

Thank you for your feedback. The current codes assume that the mode_fn returns a single scalar value. So it will not have the problems you pointed out. Our primary intention is to write an implementation that is easy to read and modify. It depends on the users to customize their codes.

Yep, I know it works fine when model_fn returns a single scalar. I won't say anything if you don't handle multiple return values at all. But you do handle multiple return values here:
