Hi, @menyifang .
Thanks for your wonderful job. I hope train a new style model, and I encounter some problems.
1.This is the 148999 steps result, and it still exist shadow problem, how to prevent this?

2.Could your give some guides on how to pick style images while some generate images are bad ?
3.As showed above. I have trained 14w steps and results are not good. What should I do? should I improve my dataset's resolution? or other method?
