Error with Img2img + ReActor (sample_dpmpp_2m_sde h_last = h)

Hello

I have these errors when I try to generate an image with img2img + the ReActor module

Traceback (most recent call last):                                                               | 0/1 [00:00<?, ?it/s]

Confirmed, problem with sampler. Whoever wrote the code didn't consider 1-step generation. Same issue with DPM++3M SDE. Simple fixes, but for now use a different sampler or 2+ steps.

@DenOfEquity I see you have already patched it! Thanks
