Training for parent discriminator

[MikeXuQ]

Hi, thanks for publishing your code. But after I reading the code, it makes me confused that the parent discriminator seems not to be updated anymore after initialized. It seems to be different from the paper. Have I ever missed anything important?
Looking forward to your answer, thanks!

hi, parent discriminator seems to be updated at line 335 of train.py through information loss backward.
(and as written in the paper, adversarial loss isn't used in the parent stage.)

Hi MikeXuQ,

The parent discriminator doesn't get trained as a usual discriminator. Instead, it gets optimized for the mutual information loss at the parent stage, along with the generator weights.

Thanks a lot!
