2d5 finetune type error

Dear Developers, I can perform inference using the script you provided, but I encounter an object type mismatch during training. Specifically, I checked the data type, and the image input is already a list, so the images are input as list(list) for ViT.
As a result, the image is also a list, causing a type error (no attribute) to occur. If I change the source code, I can fine-tune the model but can no longer perform inference. I simply use the demo dataset `finetune/data/single_turn_single_image_example.json` for finetuning test.
