It is unstable using your newest release code in 64*64 resolution,why?

Can't figure out why. In my experiment, when fading in 256x256, the model crashed.

Try train_no_tanh.py with latest data.py script.

yeah, same thing happened to me as well. In my case, the model collapsed very early on at 16*16 fade in. ( I used default value for all the hyper-parameters listed in the README)

--g_lr_max 1e-3 --d_lr_max 1e-3 --train_kimg 600 --transition_kimg 600 --beta1 0 --beta2 0.99 --gan lsgan --first_resol 4 --target_resol 256 --no_tanh

Me too, the model coIlapsed very early. BTW, the model is trained on my own data set. Is there something important??

Use train_no_tanh.py instead.

Thx!! It works. I can successfully obtain meaningful images.
