I tried to run the network inside this repository but actually when I need to update the different parts of the GAN from here I get a painfull error:

RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation: [torch.cuda.FloatTensor [1024, 128]], which is output 0 of TBackward, is at version 3; expected version 2 instead. Hint: the backtrace further above shows the operation that failed to compute its gradient. The variable in question was changed in there or anywhere later. Good luck!
I already searched online and it seems that I’m not able to do the second backward pass because the network has already updated the variables but since it’s very delicate I’m asking you a support.
