Furkan Gözükara SECourses•6/10/25, 10:20 PM

could be out of RAM

Furkan Gözükara SECourses•6/10/25, 10:20 PM

ok i am glad it wasnt out of RAM

mladoOP•6/10/25, 10:20 PM

yes me too haha, thank you regardless

Can someone help me diagnose this issue. Images from my recent fine tuned model are coming out with strange patterns particularly noticable on skin but also just overall in the image. Is it due to over training or could it be from particular grainy images in dataset?

is like specky-ness everywhere. I think it only happens after refining.

I think it might be due to the lack of distant photos I trained with... as I used mostly high detailed mostly selfies.

if your dataset has grainy images than it's because of that. If not then your learning rate is high. If your images are grainy try reducing the lora rank and re train

may I ask why it says that the total amount of epochs will be 195 by the end of the training, I am sure that I selected 200

Hi @Furkan Gözükara SECourses, I cannot get either SDPA nor xformers to work with koyha_ss on my 5090. I have used both your install and also another method recommended by Bmaltais himself 2 weeks ago (https://github.com/bmaltais/kohya_ss/issues/3096#issuecomment-2730229439).

The installation of pytorch + xformers is successful. When I check in the .venv, the xformers are indeed installed.
However during training, the CrossAttention settings simply get ignored, both if I set it to xformers and to SDPA.
No mention of CrossAttention is shown in the training logs, and I notice on the VRAM usage that this is not being enabled.
I have all the requirements on my pc (python 3.10, cuda 12.8 etc).

Do you have any advice? Are the cross attention settings working in your koyha_ss install with your 5090, xformers in particular?
Thank you in advance.

do you have python 3.10.11 installed?

Furkan Gözükara SECourses•6/12/25, 7:18 PM

i am able to use both with my installer

Furkan Gözükara SECourses•6/12/25, 7:18 PM

maybe not displaying on cmd?

Furkan Gözükara SECourses•6/12/25, 7:18 PM

did you check your speed_? which config you used?

FFurkan Gözükara SECourses do you have python 3.10.11 installed?

Dario•6/13/25, 8:24 AM

Thank you for your reply. Yes I have python 3.10.11, I am using the latest config "48GB_GPU_28200MB_6.3_second_it_Tier_1".
Speed is around 3.85s/it.
Perhaps it is indeed working but I find it strange there is no menion of this in the cmd windows. I remember the use of xformers was shown here on older installs (when using a 4090).
Do you see this in your koyha cmd windows when training?

FFurkan Gözükara SECourses do you have python 3.10.11 installed?

Dario•6/13/25, 8:28 AM

Further more, I am getting the exact same 3.85s/it speed and 27.7 GB VRAM used when I set CrossAttention to "none" in tge Koyha GUI, as when I set it to "xformers".
So that shows that there is no cross attention happening.

JJamiewhelton is like specky-ness everywhere. I think it only happens after refining.

Timson•6/13/25, 10:00 AM

my first guesst would be - some compression artefacts trained in with dataset. Another potential issue - you are trying to generate at much larger resolution than you training set

Timson•6/13/25, 10:01 AM

I was able to partially work aroung models trained on subpar datasets by doing img2img from donor image of high quality and fairly large creativity

Timson•6/13/25, 10:03 AM

It would be cool if someone found prompting techniques to improve quality (the obvious ones like "hi res image", "high quality image" have almost no effect on the generation)

Furkan Gözükara SECourses•6/13/25, 11:14 AM

3.85 is accurate

Furkan Gözükara SECourses•6/13/25, 11:14 AM

it is working

Furkan Gözükara SECourses•6/13/25, 11:14 AM

also SPDA and xFormers are same speed recently

FFurkan Gözükara SECourses 3.85 is accurate

Dario•6/13/25, 11:29 AM

Okay but if I set cross attention to "none" I get the sane speed and VRAM. That and the missing mention of this in the cmd window makes me very suspicious if this is actually working.

Furkan Gözükara SECourses•6/13/25, 11:50 AM

ah i think you should report it

because that shouldnt happen

Okay I will do that, thanks.

removing it from dataset

Furkan Gözükara SECourses•6/13/25, 10:01 PM

or in prompt after training try to prompt carefully that would generate different side eye

Is there any way to resume LoRa training after the overnight automatic Windows update that restarted my PC?

LukeJoseph•6/14/25, 6:51 PM

Hi all - followed the Flux training Lora guide/tutorial. Does my speeds seem correct for a 3090? It’s roughly 9 it/s using the level 2 workflow.

I keep seeing references to a “massive speed increase” with torch 2.5, but the 1 click installer has I believe installs 2.7? So I imagine that’s already implemented.

FluxGym is substantially faster, around 2 it/s, if memory serves me. But as I am just learning about all this, is a bit difficult for me to compare apples to apples/settings to settings. FluxGym while easy to use, doesn’t have the most friendly of interfaces when digging into additional settings.
