Hi, thanks for your great work!

I read part of your code. I guess this line (https://github.com/jy0205/Pyramid-Flow/blob/e4b02ef31edba13e509896388b1fedd502ea767c/pyramid_dit/pyramid_dit_for_video_gen_pipeline.py#L737) is used to calculate coefficient of Up(x{e{i+1}}) in formula 15, but it is different from formula 15.

Could you explain it for me (: ?

Thank you, Yanrui

Yes, this is the coefficient of Up(x{e{i+1}}) in formula 15.
