ImportError: cannot import name 'SiglipVisionTransformer' from 'transformers.models.siglip.modeling_siglip'

Traceback (most recent call last):

ImportError: cannot import name 'SiglipVisionTransformer' from 'transformers.models.siglip.modeling_siglip' (/usr/local/lib/python3.11/dist-packages/transformers/models/siglip/modeling_siglip.py)

Reproduction Steps:

1. Git clone repo
2. pip install -e .
3. chmod +x ./examples/qwen_image/model_training/lora/Qwen-Image-Edit-2511.sh
4. ./examples/qwen_image/model_training/lora/Qwen-Image-Edit-2511.sh

In step 4, lora refinement I am getting the above error. I see another issue with the same error but it didn't help resolve.

Start with examples/qwen_image/model_training/train.py and reproduce the failure using examples/qwen_image/model_training/lora/Qwen-Image-Edit-2511.sh after pip install -e .. Trace the import through diffsynth/pipelines/qwen_image.py to diffsynth/models/siglip2_image_encoder.py and compare it with the installed transformers module. Done means the Qwen Image LoRA refinement command starts without this ImportError.
