Questions about training

This happened when I reproduced the paper. Are there other tricks on loss. Unable to generate pants correctly

Hello @lgs00 , could you tell me now you get the pure noise for training？In the codes I have read before, DDIMScheduler.add_noise is always used to directly obtain the noisy target img. This is the first time I have seen the method of concat the target img with the noise. How is the noise obtained by this method?
Thank you！
