Mode collapse?

[Hierakonpolis]

Hello, I tried training on ImageNet with the default script using 4 GPUs, and the GAN stopped training generating something like this: All generated samples are similar grids. Am I missing something and are there any parameters I should be tweaking, or should I just try again?

I also run into similar problem but with my own dataset. I messed around with argument z_var and got just slightly better results. I am looking into WGAN to avoid this problem.

same happened to me.

when I trained on BigGANdeep model, things come normal, and you can try this model. But I still don't know what's the reason of the collapse of BigGAN.

@fido20160817 Hi buddy, can you provide a pre-training model of biggan-deep? I see this repo is not provided
