I use OPTM loss in EEND_EDA, and this question comes up. It is strange that the program runs for some time and then terminates. How can I solve the error?

I do not know the reasons. Look forward to your reply.
Thanks a lot for the implementation, it's great to have to have all three possibilities in the same code-base to be able to benchmark those.
We have something similar in Asteroid, (PITLossWrapper
)[https://github.com/mpariente/asteroid/blob/master/asteroid/losses/pit_wrapper.py#L8], which can convert any loss function into a PIT loss function.
I've had a look at the Hungarian algorithm in the past and thought about integrating it but I thought the time spent on CPU-GPU transfers would outweigh the gain of the Hungarian algorithm.
I cannot access your paper so I don't see if you made the experiments, but I guess yes. Did you actually gain some time or lose some time when using OPTMLoss
against FastPITLoss
?
Thanks,
Manu
