can't use img2img and highres fix

[VictorJulianiR]

Describe the bug If I try to use high-res fix with any new sampler, or, i try to use igm2igm with an image that's not exactly 512x512 (no matter the sampler), I get an error on SwinIR_4x

dev\stable-diffusion-webui\modules\images.py", line 220, in resize assert len(upscalers) > 0, f"could not find upscaler named {opts.upscaler_for_img2img}" AssertionError: could not find upscaler named SwinIR 4x

I have this upscaler in the following path "stable-diffusion-webui\models\SwinIR\SwinIR_4x.pth"

To Reproduce Generate any picture with high-res fix using the new samplers (adapative, karras) or Try img2img with any sampler and any picture that's not 512x512

Expected behavior No erro should occur.

I am having a similar problem. However, my img2img upscaling seems to be working normally. Describe the bug If I enable Highres.fix and change the resolution to anything other than 512x512, I get the following error:

File "C:\Stable Diffusion\stable-diffusion-webui\modules\images.py", line 220, in resize
    assert len(upscalers) > 0, f"could not find upscaler named {opts.upscaler_for_img2img}"
AssertionError: could not find upscaler named

The Highres.fix option was working correctly yesterday. I tested some images I made yesterday thru the PNG info tab, and I could not reproduce those images without running into the error To Reproduce Run txt2img with the Highres.fix option enabled Expected behavior no errors

ok it seems I had a null option chosen in the settings>upscaling>upscaler for img2img dropdown. I chose "None" and it works properly. I also tried some other upscalers and it seems to have solved the issue.
