[Bug]: Dreambooth can not start training

[doubtfire009]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits of both this extension and the webui

What happened?

I use the Stable-Diffusion-webui to train my own pics. But the dreambooth fails to start training.

Steps to reproduce the problem

1. I first create a new model
2. Fill all the parameters
3. Click the train button to train.

Commit and libraries

I start in the Stable Diffusion Webui

Command Line Arguments

No

how to solve this problem?

[doubtfire009]

I solved the issue by using diffusers==0.25.0 in requirements, which uses diffusers>=0.25.0.

I was enlightened by the log: https://www.kaggle.com/code/aisuko/using-civitai-checkpoints-lora-with-diffusers

Because the diffusers>=0.25.0 will remove the function _modify_text_encoder. So I suggest the author need to update the codes.
