FutureWarning: Passing `image` as torch tensor with value range in [-1,1] is deprecated.

Thank you for sharing this great codebase! When I tried the quick example for Cat Cookie with scripts/main_stable_diffusion_cookie.sh, I noticed a warning from the diffusers package as follows.

Found 100 images in the folder /tmp/result_cookie

Is this something that I should be careful? Was this warning already there in your experiments? If not, maybe this is due to a new release of diffusers. In that case, I will greatly appreciate it if you can share the version you used for diffusers.

In case it helps, this issue might be related to https://github.com/huggingface/diffusers/issues/3876. Thank you very much for your time.

Yes, I have seen this error. I think it is raised due to image parameter to StableDiffusionImg2ImgPipeline which we used for image variations. I think the desired range for image in this API is indeed [-1,1] so we can ignore this warning.

Got it. Thanks for the prompt response!
