https://postimg.cc/m110vv0y Extension Version b32d8fe8 (Fri Apr 7 16:05:28 2023)

I format the windows and I installed a new webui, but it's the same symptom

Is there a solution?

Thank you always for your hard work

[Symbiomatrix]

Hello again. So you're saying that latent lora separation broke. What's the original file's created / modified date? Do you happen to know which version of webui and the extension you were using to generate it, before the windows format? I haven't gotten latent mode working properly yet, but if you could try to downgrade the regional extension to the version that worked (according to the file date), we may be able to pinpoint the faulty commit. It might also be caused by the webui version, but that's more difficult to test, so we'll start with the extension.

Edit: Is it from before or after we fixed #32?

Alright. Can you try this version and see if it works correctly? Also, please run with debug toggled and copy the output. https://github.com/Symbiomatrix/sd-webui-regional-prompter/tree/Ddim1 Or this one: https://github.com/hako-mikan/sd-webui-regional-prompter/tree/b772bfec90670030e95df8ebdf509ade927f6ff5 Basically, just need to overwrite rp.py and reload.

[Symbiomatrix]

Okay, so more likely caused by a webui version change. Let's try to compare a simpler prompt, standard dimensions and no hires. I ran this on the 14/3 version, it probably won't be exactly the same for you as there were some seed breaking changes. Is the quality of the image below similar to what you've had before? And does your current version show the same quality degradation you posted above for these settings?

[freebag668]

https://postimg.cc/gallery/2DQGVkh I set it up and applied it similarly b32d8fe8 (Fri Apr 7 16:05:28 2023) Image quality error

[Symbiomatrix]

So if even basic settings aren't doing well, I guess it's something to do with the new lora application method. I can't upgrade to that version for now, perhaps you could try downgrading to the previous version, https://github.com/AUTOMATIC1111/stable-diffusion-webui/tree/a0d07fb5807ad55c8ccfdfc9a6d9ae3c62b9d211 (Unless hako would like to take a shot at it.)

[Symbiomatrix]

I think I might finally have a breakthrough. I upgraded to the latest locon extension from my old one (I think it's the 04/03 version, 2e9a79533987e6b454c87705fc4e178febac4fe0), and I'm finally getting garbage, with the same settings. It's possible, seeing as some additional lora functions were overridden and that's pretty much the only difference between our debug printouts. Can you disable / downgrade your locon extension and see if it helps?

Edit: But it might just be from omitting easynegative. Ugh. You don't happen to be missing that embedding, right? Do you happen to have the list of extensions you had installed before the format?

[hako-mikan]

@Symbiomatrix Thanks for the validation. In my environment, LoCon extension appeared to be unrelated. After all, what are the conditions under which this problem occurs?

[Symbiomatrix]

@hako-mikan Checkpoint: meina pastel v4 Loras: roxyMigurdiaLora_offset , megumin_v10 (not sure which is that particular one, I used "Megumin (KonoSuba) - arch wizard outfit") We're attempting to replicate the results in https://postlmg.cc/rd26VT0z . So far, every attempt has fallen short of it - so you might say, any conditions. We know for sure regional's version was https://github.com/hako-mikan/sd-webui-regional-prompter/tree/99ea794c8512caf24f469527d97f06a17d74f6d8 . The webui version is unclear, but we tried either the latest one, or before the lora change, and on my end 14/3.

Since perfect replication might be impossible (due to various undocumented settings or extension overrides in play), I tried to test a less complex prompt: 2girls, bento BREAK[common] <lora1> BREAK <lora2> I'm under the impression that the migurdia lora might be malfunctioning when used in regional, as without easynegative it's showing various forms of discolouration, even with a lower weight, compared to a non regional prompt. Megumin does not suffer the same level of degradation. Does it being "offset" have any relevance?

Observe: Regionless, crisp detail.

Migurdia one side (low weight), looks like a picasso whereas other side is unchanged.

Migurdia both sides, completely off.

Megumin on standard weight holding up quite well.

In fact, even when the region is 1,0 this degradation occurs, so that might be something that can actually be compared on the tensor level. I hadn't thought of that before.

EDIT: Correction, thanks to freebag having posted the full page, we do know his previous commit - it was indeed the the latest webui.

[Symbiomatrix]

@freebag668 Okay, I think the results are at least somewhat similar. It's not as pronounced as migurdia, but definitely has a discernable effect. I wonder if xformers' nondeterminism might be causing slight variations; megumin looks significantly different (but then I'm probably not using the same lora as yours, so that might be the reason).

[freebag668]

Is there anything else I can test?

[hako-mikan]

There are certainly cases where the quality is lower, but this has been the case for some time. I was able to reproduce the example I am giving in the ReadMe, but at the same time, applying LoRAs such as megumin produced images with quality issues. In general, when multiple LoRAs are used, the quality tends to drop due to the interaction. This is avoided by reducing the strength of the LoRAs or by applying them in a Block weight. Therefore, I think that the quality degradation is normal.

[hako-mikan]

Are the following issues related to this? https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/9118 https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/9207

[Sakura-Luna]

On earlier versions of the WebUI, the results were also a bit worse.

[hako-mikan]

What happens if you use the settings you're having trouble with and only decreasing strength of LoRA?

[Sakura-Luna]

If you just turn off the extension, you can't get such a serious blurred result. If you reduce the weight of both to 0.5, the left side still has a similar bokeh but lighter.

I'm going to try an older version of the extension.

[Sakura-Luna]

I reverted to the earliest extended version, no any improvement, you can test Latent Couple + Composable Lora.

Based on my own testing, I think the problem lies with the checkpoints and the Lora model itself, changing any of them can see a significant improvement.

[Sakura-Luna]

What extension is causing so much "up_model" output?

I rolled back the extended version many times, until the Latent just added, and none of the similar results can be reproduced. You can go back to the old version through the extended commit history, and then feedback which version can get the effect you expected, otherwise it is difficult to locate the problem.

[Symbiomatrix]

What extension is causing so much "up_model" output?

That should be regional, on webui 25/3+ version. There's a ton of layers which loras affect. Not sure under which circumstances it's up_model or weight.

def changethedevice(module):
    if type(module).__name__ == "LoraUpDownModule":
        if hasattr(module,"up_model") :
            print("up_model")
            module.up_model.weight = torch.nn.Parameter(module.up_model.weight.to(devices.device, dtype = torch.float))
            module.down_model.weight = torch.nn.Parameter(module.down_model.weight.to(devices.device, dtype=torch.float))
        else:
            print("weight")
            module.up.weight = torch.nn.Parameter(module.up.weight.to(devices.device, dtype = torch.float))
            if hasattr(module.down, "weight"):
                module.down.weight = torch.nn.Parameter(module.down.weight.to(devices.device, dtype=torch.float))

You can go back to the old version through the extended commit history, and then feedback which version can get the effect you expected, otherwise it is difficult to locate the problem.

We know for certain which webui and regional version he had been using: webui was the latest, the commit is shown at the bottom of this image from the issue. And the extension version was right before and then after the lora fix PR. What is unknown, is whether there were other extensions in play, or specific webui settings. That regional might've somehow run on attention instead of latent seems plausible quality wise, but attention completely lacks lora separation; the results are very different in attention compared to latent with a low weight on migurdia. In any case, if there's some magical setting which can improve latent's lora stability, or an unknown bug in the implementation which was bypassed, the search might be worthwhile.

Attention, identical settings:

Latent, low weight on migurdia:

[freebag668]

If I knew more about computers I could help, but I'm sorry I can't.

[Sakura-Luna]

I switched to the latest WebUI, and then used the same extension version as his (525741c), and got terrible results, and in my case the output was "weight", I believe there are other factors causing the difference.

[hako-mikan]

I forgotten deleting print("up_model"). It's for debugging.

[Symbiomatrix]

@Sakura-Luna It's an interesting difference, but likely a red herring. I asked freebag to copy his debug printouts earlier in this issue, and he still receives the up_model message along with the degradation.

https://anonfiles.com/f461Pajez9/mikan_txt

@hako-mikan Question: Would it make sense that running a single lora in base, with base ratio = 1, be different compared to regionless as well? Does the latent method alter the application that much?

[hako-mikan]

@Symbiomatrix In that case, result will be same, but not same now. So something wrong.

[hako-mikan]

@Symbiomatrix Not exactly. It is not exactly the same because I followed the Composable LoRA and erasing LoRA's impact on negative prompts. Maybe this is where it is affecting. I will test turning off that feature.

[Symbiomatrix]

You mean, that in denoiser_callback only text_cond is flipped back via params.text_cond[b+a*self.batch_size] = ct[a + b * areas] and not text_uncond?

[hako-mikan]

No. When applying LoRA to Textencoder. Weight of loRA is set to 0. Also, Weight of LoRA is set to 0 when calculating in unet of uncond.

[Symbiomatrix]

Ah, okay. I know that part - te_llist & u_llist's additional elements. So that's what it means.

[hako-mikan]

We can disable this feature. comment out line 1296 #regioner.ndeleter()

Surprisingly, my sample in README get terrible result. But result of megumin was improved.

Sorry I'm sleepy(2:00 AM now in japan)

[Symbiomatrix]

My bad, I hadn't noticed the time. Much obliged. Good night.

Can confirm: Base lora becomes identical (both single and dual lora), but in region megumin alone at weights of >0.2 causes the other side to become noise very quickly. Migurdia less so, oddly. Unbalanced?

Edit: Te_llist weights seem to have little effect on the output. for these loras at least. Here, megumin's general u only is nullified. And here, megumin's te + u.

[hako-mikan]

LoRA settings regarding negative prompts have been added as an option. The default is off; turning it off seems to give better results when using LoRA such as megumin.

That update was not released to fix your problem.

Here is the extension version you used before, you can change the name to sd-webui-regional-prompter after decompression, and then copy it to the extensions folder under the SD installation location.

[Symbiomatrix]

Hello freebag. Sorry I'm late, but #120 should expand sakura's negative parameters to control individual loras, so you can mess around with those once merged. Wrote an explanation about it in known issues.
