Hi,

Would you like to tell me why you added scalar '79' in front of the cross entropy (RVAE, Line 110)?
loss = 79 * cross_entropy + kld_coef(i) * kld

when I remove 79, kld can go to zero very fast.

Hi, thanks for your reply. We have to use kl annealing to alleviate kl vanishing issue in this model. I think it is the same.
