training generated images that appear pixelated or mosaic-like.

Hello,
I have been attempting to train a model using the code you provided, during which I disabled the multi-GPU training functionality. Throughout the training process, I observed that the loss was decreasing as expected. However, other metrics started displaying NaN values. Additionally, the model generated images that appear pixelated or mosaic-like.
Could you please provide guidance on how to resolve these issues?
Thank you for your assistance.
