The following error came out when implementing with reference to fineGAN. I can’t solve it after trying a lot.
Is there any good way?

        self.fake_labels = \
            Variable(torch.FloatTensor(self.batch_size).fill_(0))

        nz = cfg.GAN.Z_DIM
        noise = Variable(torch.FloatTensor(self.batch_size, nz))
        fixed_noise = \

        hard_noise = \
            Variable(torch.FloatTensor(self.batch_size, nz).normal_(0, 1)).cuda()

        self.patch_stride = float(4)    # Receptive field stride given the current discriminator architecture for background stage
