Add Wan2.2 VACE - Fun

[linoytsaban]

https://huggingface.co/alibaba-pai/Wan2.2-VACE-Fun-A14B

diffusers format: https://huggingface.co/linoyts/Wan2.2-VACE-Fun-14B-diffusers

Example with Reference(s)-to-Video:
Notes:

1. the boundary_ratio is set to 0.875 by default, I didn't experiment with the values
2. the videos attached were generated with Wan2.2 VACE using lightx2v LoRA for an 8-step inference
3. all other VACE use cases should also be applicable (see Wan VACE #11582 for more examples)

Could we check if the failing test is not being introduced in this PR?

[J4BEZ]

Very Awesome!
I really appreciate your hard work🙇‍♂️

[linoytsaban]

@sayakpaul@yiyixuxu I think current failing test is not related

[sayakpaul]

Indeed. The failure I pointed out has now gone 👍 Thanks for the work, Linoy!

[bhack]

@linoytsaban Does this support Masked V2V?

[luke14free]

@linoytsaban I noticed that using the lightx2v lora causes a lot of warnings about mismatching layers in console and also produces much worse results than yours. maybe it's the wrong lora link?

[00Neil]

Thank you for your hard work on this! I'm wondering if this model supports multi-GPU inference. The reason I ask is that I currently have 8 RTX 4090 graphics cards available, and using a single 4090 leads to an out-of-memory (OOM) error.

[sayakpaul]

@00Neil we don't yet support exotic forms of parallelism within the library. #11941 is in the works.

We have some guidance on how to reduce memory consumption and other speedup-related things we support from the library:
