Hi @AndPuQing,

Thank you for submitting this excellent PR! I've thoroughly tested the code, and it seamlessly integrates with the latest diffusers (0.25.0).

However, during my testing, I observed a significant disparity between the generated adversarial examples before and after, as illustrated below (left represents the original, while the right depicts the adapted version). Could you provide any insight into this observed difference?

Your cooperation is greatly appreciated.
