@liminn @silence1114 It's because of the normalize operation`transforms.Normalize((0.5, 0.5, 0.5), (0.5, 0.5, 0.5))`,doing unnormalization before output should solve the problem.`real_cpu = real_cpu/2.0`,`real_cpu = real_cpu + 0.5`,then`vutils.save_image(real_cpu, 'result/train/real/real_samples_epoch_%03d.png' % (epoch))`

Thanks for your timely reply!😀 哈工大nb！
