Artifacts in generated images

[douhaoexia]

Hello , I run the cyclegan model with several datasets. But there are spots artifacts in generated images like this :

Any reasons and solutions to this problem ?

It is called mode collapse. It sometimes happened when your dataset is too small. Try using some data argumentation or use a larger dataset.

I also have this problem. There are multi-color spots in the generated images. Could you tell me the solution?

Is your output one-channel image? It should not have a chromatic color?
