Serious code bug in your demo_gr.py !!!

[xyLiu339]

There is a serious code bug in the demo_gr. When handling the img2img task, at line 74, after scaling the pixel colors from 0 to 255 down to 0 to 1, it fails to normalize them to the range of -1 to 1. As a result, there is data deviation in the subsequent VAE encoding process and subsequent processes, causing the generated image to have an obvious color shift although it shows fidelity to the original image in terms of content. This phenomenon has been proven through experiments. In contrast, the input image is processed correctly in demo_st (normalized to the range of -1 to 1). If anyone encounters the same problem, please provide your feedback. Thank you.
