Description

Key Code:
edit_image = [Image.open("image1.jpg"), Image.open("image2.jpg")]
image_3 = pipe(prompt, edit_image=edit_image, seed=1, num_inference_steps=40, height=1328, width=1024, edit_image_auto_resize=True)

Comment:
It looks like 'List' is not match the argument 'edit_image' of pipe.

Research direction

Start in diffsynth/pipelines/qwen_image.py, especially the process method and edit_image_auto_resize shown in the traceback. Reproduce the Qwen-Image-Edit example with the two-image list and inspect the expected edit_image input shape. Done means the example no longer raises AttributeError and the supported input behavior is clear.
