Question about stage 3

[layumi]

Hi @wtupc96

Yes. In the stage 2, I do not train the D (by setting loss weight to zero) and keep training G.

[wtupc96]

But what about the false(I think) instruction from the random initialized D when training G? 发自我的小米手机 在 Zhedong Zheng <[email protected]>，2020年6月11日 下午6:04写道： Hi @wtupc96<https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fwtupc96&data=02%7C01%7C%7Cc4528ae46e5b49d2ecfe08d80deed1ae%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637274666649084655&sdata=M%2F4ceqWqKN789%2Bc1HWCjp5ZMTBFmfIRvFN%2BzDPcJ6ZM%3D&reserved=0> Yes.

Sorry. I may not get your question.

In the stage 2, D loss is set to zero in this line.
https://github.com/layumi/Seg-Uncertainty/blob/master/trainer_ms_variance.py#L223
So discriminator will not affect G anymore.

I kept the loss calculation but it will not be back propagate to G.

Oh, I see. Thanks for your reply!
