errors while trying to "convert_animatediff_motion_module_to_diffusers"

[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

Hi @lulu1315 thanks for flagging. I've opened a PR to support converting AnimateDiff safetensors format files to Diffusers.
