Hi Thanks for your wonderful work.
I am trying to run your code (Wan2.1 based) but I am getting error like this : *** AttributeError: 'UniPCMultistepScheduler' object has no attribute 'scale_noise'.

I will be appreciated if you could let me know how to solve this error! Thank you.

Hi,

It appears that Wan2.1 has changed the default scheduler from FlowMatchEulerDiscreteScheduler to UniPCMultistepScheduler. We can manually revert it back. https://github.com/bcmi/Light-A-Video/blob/main/lav_wan_relight.py#L32

Thank you for pointing out the issue and the code has been fixed now.
Feel free to discuss any other issues. Have fun ^^!
