Model collapse while Training Phaze-A

Post by hyoer »


I am trying to train phaze-a with decent amount of data (2k B images), the stojo preset, with a batch size of 8 and mixed precision enabled, and everything else the default settings, but something weird is going on. The output images is always pale bluish. I only managed to trained the model for 10k steps before it got corrupted. Is that expected for phaze-a?

I also tried training villain using the exact same dataset, and it worked, so I dont think the problem is with the dataset.

Unfortunately a model can collapse at any time. I'd suggest trying again, and if you still have problems, try reducing your Learning Rate.

Yeah, basically reduce learning rate. More complex models need lower learning rates.

If you are using Mixed Precision on StoJo preset, then I would also suggest raising the Epsilon Exponent to -5 (That model has a nasty habit of hitting NaNs with Mixed Precision otherwise, which is INCREDIBLY frustrating).

My word is final
