Some of the code provided does not work

[jcForDream]

Hello.
Some of the code provided does not work.
(1) There are 5 experiments in the experimental part of the paper, which file is the code of all the experiments?
(2)The code I run wgan.py will oscillate strongly after the training times exceed 7500, why?
(3) Why do you take only 5000 iterations when running wassertein distance?

Thanks!
