Great work!
I have observed that some generated images by official checkpoint of CelebA64 are NaN . This might be caused by "Batch Norm Statistics Readjusted" introduced by the paper, becuase without BN statistics readjusted, none of the generated images are NaN (but the generated iamges quality have a sharp decline). Do you have this problem and how to deal with it?
Thank you for the excelllent paper and the great repo!

The same problem also occurs on CelebA256.

Same here on CIFAR10 (using --temp=0.6 --readjust_bn).

When I run the official eval script to generate images on CIFAR10 (official checkpoints) I get the same behavior...
