Weired style synthesis result

[rkomatsu2020]

Hi, I have tried to implement CoCosNet using SPADE in Generator. When the model finished the training, the output result showed weired result. Below figure shows the translation result for animal to animal translation. Left column is the content images, middle one is the style images and right one is the results. The trained Generator output the entire of style images.

Here is the normalization function SPADE following the code. Could you give me some advices? Thank you.
