About args: multi-channel for image inpainting

[JHang2020]

Hello! In partialconv2d.py :
if 'multi_channel' in kwargs:
self.multi_channel = kwargs['multi_channel']
kwargs.pop('multi_channel')
else:
self.multi_channel = False
Why should we set the args: multi-channel to be "True" if we want use Pconv for image inpainting? I think it has no effect when we use it for image inpainting if multi-channel is set to False. It seems like a waste, but it doesn't make any difference to the result.

Please correct me if I make some wrongs.
