Thank you for sharing the code with the public. I'm trying to execute the cGAN.py script and encountered the following error Could you please help me resolve the issue?

Hello, unfortunately I am on holidays and I will not be able to reply before October, since I am gone for a month. I cannot see much from the error, I remember that after some epochs there is some operation that updates a variable (probability of no change Pu I think?) and then the whole dataset has to be formed again and that's where your issue is. There is some reshape that does not go as planned. I would have to investigate a bit, and I really don't have the time now, sorry 😔

Have a nice vacation! Thank you for providing details on the possible issue. In the meantime, I'll try to debug it from my side. Thanks again!
