pesq can be used as a loss?

hi, can pesq be used as a loss? i.e. if pesq is differentiable and pass gradient flow?
for example, is si-snr is implemented by pytorch, it can be used as a loss, while it can evaluate the performance.

Unfortunately not. The pesq metric of this repo in API to this implementation, which is a python wrapper to the original c implementation.
