运行406_conditional_GAN时,出现以下错误:
RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation: [torch.FloatTensor [128, 1]], which is output 0 of TBackward, is at version 2; expected version 1 instead.
请问是什么原因?

原因:在计算生成器网络梯度之前先对判别器进行更新,修改了某些值,导致Generator网络的梯度计算失败。
解决方法:按图修改该部分代码。
