[Bug]: img2img quit early

[kjlee18]

Is there an existing issue for this?

• [X] I have searched the existing issues and checked the recent builds/commits

What happened?

When I generate images at the img2img tab, the inference step quits early. For example, if I set the inference step as 20 and denoising strength as 0.99, it works fine. However, if I set the denoising strength as 0.5, the inference ends at step 11. Even more, when the denoising strength is 0.1, it ends at step 3..

Since the webui works fine on txt2img tab, I doubt if the issue is related to denoising strength

Steps to reproduce the problem

I just git pull to the latest version. And reverting to previous version or re-install generate the same issue

What should have happened?

Generate images with specified inference steps independently with denoising strength

is it a bug? some samplers simply do exit early when they consider image done. and you've tried to paste image of console log? just paste text itself, uploading image that shows text is a nighmare to work with.

I changed the console log to text. As you mentioned, I tried with several samplers (Euler a, Euler, ..., DMP++2M), but the inference ends early all the time. I found a similar issue #3343, but it is an old issue..

This is a setting. You can turn it on if you want exact steps.

In Settings / Stable Diffusion / "With img2img, do exactly the amount of steps the slider specifies (normally you'd do less with less denoising)."

Thank you very much!! I spent a lot of time debugging this.. By the way, anyone knows where the code locates? (I guess if the option is not turned on, the steps will be set as [denoisint_strength * steps]

@kjlee18 it is also documented on the tooltip of label of the denoising slider: "With values below 1.0, processing will take less steps than the Sampling Steps slider specifies"

I have also been getting this issue. on this collab. https://colab.research.google.com/github/TheLastBen/fast-stable-diffusion/blob/main/fast_stable_diffusion_AUTOMATIC1111.ipynb#scrollTo=p4wj_txjP3TC. the issue seems to be different each time but usually after a few attempts of img to img it stops working. txt to img still works but img to img breaks in various ways. I have also gotten this error its not consistent:
