File "/mnt/workspace/stable-diffusion-webui/extensions/sd-webui-EasyPhoto/scripts/easyphoto_train.py", line 78, in easyphoto_train_forward
image = process_rotate_image(image).convert("RGB")
File "/mnt/workspace/stable-diffusion-webui/extensions/sd-webui-EasyPhoto/scripts/easyphoto_train.py", line 229, in process_rotate_image
return img2
UnboundLocalError: local variable 'img2' referenced before assignment

I debugged it and found that the sentence of code "exif.get(orientation, None)" returns None.

Thanks for your debug, we now fixed it in #PR70 and we will enhance our UT before PR
