[lulu1315]

Describe the bug

i'm trying to use different motion adapter for animatediff . these ones especially :
https://huggingface.co/ByteDance/AnimateDiff-Lightning/blob/main/animatediff_lightning_8step_comfyui.safetensors
https://civitai.com/models/331718/bubbling-rings-or-animatediff-motion-lora

when i try to convert the safetensors to diffusers i keep having errors.

Reproduction

python3 scripts/convert_animatediff_motion_module_to_diffusers.py --ckpt_path animatediff_lightning_8step_diffusers.safetensors --output_path animatediff_lightning_8step_diffusers
or
python3 scripts/convert_animatediff_motion_lora_to_diffusers.py --ckpt_path animatediff_lightning_8step_diffusers.safetensors --output_path animatediff_lightning_8step_diffusers
