seujung commented on issue #13847: Spectralnormalization GAN seems to be seriously broken URL: https://github.com/apache/incubator-mxnet/issues/13847#issuecomment-453888598 The problem is related to the update u matrix. I found that parameter is not updated using setattr method. When changing code like this, the paramter is updated successfully. self.params.setattr('u', _u) --> with autograd.pause(): self.u.set_data(_u)
