Cannot train LoRA in WebGUI

[SingleZombie]

If we train LoRA in the WebGUI, we may get this error.

RuntimeError: element 0 of tensors does not require grad and does not have a grad_fn

This is because your LoRA implementation is outdated in diffusers >= 0.25.1. I notice that you have changed the diffusers version from 0.21.4 to 0.25.1. The old version works. So I suggest you either modify the diffusers version in Readme or upgrade your LoRA implementation.
