is it a bad idea when training a character lora (SDXL) to use two sets of the same images - one in 1024x1024 and one in 896x1152 to be more flexible depending on which aspect ration/resolution i want to create my images with? and if it is not a bad idea, should i create one concept per resolution? would i have to use 2 concepts with reg images?

dschulie•8/3/25, 9:42 PM

and is there a benefit or downside in using full resolution images (in the correct aspect ratio) or should i downscale everything to the exact resolution (1024x1024/896x1152) or does it downscale on its own when the source images are higher resolution

lots of shared vrma

Furkan Gözükara SECourses•8/3/25, 10:20 PM

it must be very slow

Furkan Gözükara SECourses•8/3/25, 10:21 PM

ostris still doesnt support block swap

Furkan Gözükara SECourses•8/3/25, 10:21 PM

interesting did he add block swap?

Furkan Gözükara SECourses•8/3/25, 10:21 PM

it is not as slow as much i would say

Furkan Gözükara SECourses•8/3/25, 10:21 PM

what is your training resolution?

Ddschulie and is there a benefit or downside in using full resolution images (in the corre...

Furkan Gözükara SECourses•8/3/25, 10:22 PM

i would say make all images exact resolution

Furkan Gözükara SECourses•8/3/25, 10:22 PM

you probably can train with 2 different aspect ratio

Furkan Gözükara SECourses•8/3/25, 10:22 PM

make sure to enable bucketing

dschulie•8/3/25, 10:23 PM

thank you. would i need both sets of reg images? so in the end 2 image concepts and 2 reg image concepts? or would you just throw them all in one folder (1 image folder, 1 reg folder)

Ddschulie thank you. would i need both sets of reg images? so in the end 2 image concepts ...

Furkan Gözükara SECourses•8/3/25, 10:36 PM

good question. probably having different aspect ratio would help

Furkan Gözükara SECourses•8/3/25, 10:36 PM

you training sdxl right?

dschulie•8/3/25, 10:36 PM

yes sdxl

Furkan Gözükara SECourses•8/3/25, 10:37 PM

yes it should work

dschulie•8/3/25, 10:37 PM

currently i have two folders, one with 1024x1024 and one with 896x1152. so the question is: should i create one concept in onetrainer with both resolutions in one folder, or separate them and have two concepts

dschulie•8/3/25, 10:37 PM

and would i add 2 reg image concepts for either resolution

dschulie•8/3/25, 10:38 PM

or one concept with both reg resolutions inside

Furkan Gözükara SECourses•8/3/25, 10:49 PM

in one trainer

Furkan Gözükara SECourses•8/3/25, 10:49 PM

just add them as 2 concepts

Furkan Gözükara SECourses•8/3/25, 10:49 PM

and properly set their repeat count

dschulie•8/3/25, 10:51 PM

so 2 concepts for the images (1024x1024 and 896x1152). i have 50 images each. since it's 2 concepts do i use 50 or 100?

Ddschulie so 2 concepts for the images (1024x1024 and 896x1152). i have 50 images each. si...

Furkan Gözükara SECourses•8/3/25, 10:52 PM

logic simple

Furkan Gözükara SECourses•8/3/25, 10:52 PM

at 1 epoch you have 100 train images

Furkan Gözükara SECourses•8/3/25, 10:52 PM

then you should use 100 reg images

Furkan Gözükara SECourses•8/3/25, 10:52 PM

50 from each in that case

FFurkan Gözükara SECourses lots of shared vrma

JonkoXLOP•8/4/25, 7:05 AM

due to block swap and vae_cache_cpu enabled.
interestingly enough it made no difference in my case for speed whether i turn it on or not for that 480z360 dataset , tested speeds with and without. (without it fits in dedicated vram without shared mem as well)
(though usualy vram bottleneck does limit speeds in other instances)

JonkoXLOP•8/4/25, 7:06 AM

i am still messing around with what barely fits in vram, apparently as long as there is about 1gb vram dedicated available it will run full speed (400 watt at 70% power limit)

JonkoXLOP•8/4/25, 9:57 AM

For Wan2.1 T2V using (25 videos) 480x360@61 and (23) images 960x720 fits just perfectly in an RTX 5090. Wondering about the results, but this is the most I was sable to cram into the VRAM without going overboard and not using any offloading / shared vram

JonkoXLOP•8/4/25, 9:57 AM

FFurkan Gözükara SECourses yes i will do detailed test

Yesterday, I extracted a LORA from my Dreambooth model (of my character) that I trained in Kohya GUI on the FLUX.dev model. I wanted to see how the LORA would perform with the Flux Krea model, but unfortunately, it doesn't look great.

I guess I'll have to train a new LORA specifically on the Flux Krea model, or train an entire Dreambooth model from scratch.

JonkoXLOP•8/4/25, 1:13 PM

Makes sense I guess

AiInfluence•8/4/25, 3:05 PM

I can confirm. Lora trained on Dev inferenced on krea is not that good

AiInfluence•8/4/25, 3:05 PM

But a checkpoint with krea Lora works

cyberbol•8/4/25, 3:12 PM

I'm currently training a test LORA on the wan22 low noise model, specifically a LORA for a person or character. From what I understand, it's best to train it on a low noise model. It's a fast training, only 30 images in diffusion pipe wsl. It should take about 1.5 hours.

AiInfluence•8/4/25, 3:13 PM

lmk how it went

AiInfluence•8/4/25, 3:13 PM

I tried wan 2.2 t2i and I was very disappointed

AiInfluence•8/4/25, 3:13 PM

text was all wrong and textures / quality same as krea

cyberbol•8/4/25, 3:13 PM
