[bug report] wrong implementation of gradient clip in WGAN?

[KK666-AI]

Dear author,

Thanks for your friendly implementation of popular GANs. I am reading your implementation of Wasserstein GANs, and notice that the gradient clip operation is placed after optimizer.step as seen in this line.
Typically, in pytorch, the gradient operation is placed before the optimizer step.

pls have a check.

As you can see in this line for p in self.D.parameters(): this is not performing gradient clipping but params value clipping
