But for lora training is 7hr mandatory?
But for lora training is 7hr mandatory?
SAnd epoch should be 200
Fyes flux is slow to train .
F200 is best number for 15 images
Fbut if you need speed
Fyou can increae learning rate and reduce epoch
Fand sacrifice some quality
SOk sir 
DI have a photo with dimensions 1080 x 1920 (from TikTok). How can I make it 1024 x 1024? Can I directly follow a tutorial like in a video using the Ultimate-Batch image pre-processing tool? Do I need to check (mark) 'resize without cropping (center image and add white background)'?
Or do I need to edit it manually first using an application like Photoshop?

Fyou can use this
Ffirst do 1024x1024 cropo
Fthen resize
Uhello 
For finetuning we used flux dev so far, I was wondering if we could use hidream , chroma or wan 2.1 txt to img for finetuning instead of flux dev?

Fyes all can be used i think
PDr, I was trying to use Flux Schnell with your Kohya configs used in Flux Dev finetunning. The model that it saves is too large (24GB) even though Schnell has less than 17GB and I was trying to train with 50 images only. Do you have any idea what could be wrong?
Fschnell is not 17gb
F
Fyou are probably using quantized + T5
PI thought it would be faster to train
Fnope
Aalways train on fp32
Athen inference on fp16<=
Athe logic is to save time on inference not on training for the best quality
LGood morning, gentlemen, i've been using Tier1_48_GB_Faster_v2.json for dreambooth on runpod and constantly getting the training terminated on text encoders training part
So,
subprocess.CalledProcessError: Command '['/opt/environments/python/kohya/bin/python3.10', '/workspace/kohya_ss/sd-scripts/sdxl_train.py', '--config_file', '/workspace/kohya_ss/outputs/config_dreambooth-20250719-133856.toml', '--max_grad_norm=0.0', '--no_half_vae', '--train_text_encoder', , '--learning_rate_te2=0']' returned non-zero exit status 2.
As i understand kohya wants non-zero parameter for text_encoder2
should i insert the same as on te1, 0.000003?

Fhi what is the exact message?
Fit could be out of RAM
LHey guys. I'm currently training a flux style finetune using kohya with a dataset consisting of around 1800 images total. When leaving the max epoch to 0 (default) it was automatically set to 6. This seemed strange to me, I've never used a dataset this large. I'm using the "Batch_Size_7_48GB_GPU_46250MB_29.1_second_it_Tier_1" preset as provided by Dr. Furkan. Should I tweak another variable like learning rate for a dataset this big? I set max epochs to 10 and it says it will train for 20 hours on an A6000 GPU. I thought I'd ask before I have it train for 20 hours for it to end up being trash.
LCanceled it for now just in case someone more experienced tells me I've made a fatal error.
Fare these 1800 images are consistent?
Ffor 1800 images i recommend train up to 15 epoch , take a checkpoint every epoch and compare later
LThanks for the response! They are high quality screenshots from a show with a unique art style, consistent in style only. All of them are uniquely captioned in the same format to describe the image, with a triggerword for the style at the start of the caption. I'll try as you suggested. One more question: Can I train 10 epochs, and with the resulting model, continue training for another 5 epochs in a separate instance (using the resulting model as a base) to get the same or similar result as if I were training 15 epochs from the start? A checkpoint per epoch would require me to regularly offload the models onto another server due to disk space, risking messing this up and epochs not saving.
LAlso, although maybe not particularly relevant. They are actually 2 sets of the same 900 images in different aspect ratios, according to my own testing and other testing I've seen, training on different aspect ratios improves results. Particularly with style finetunes. Never tried it with this many images though.
LThat was exactly it.

Fwith our config 10+5 = 15 from 0
Fwell it should work decent
Fmake sure to enable bucketing
Fyes batch size 2 for dreambooth requires huge vram and ram
Fbut lora works great
Awhat config should i use on H100 @Furkan Gözükara SECourses batch size 7 48gb or 48gb Q1? whats the best quality?
LIs 20 images enough for dreamboothoing? or i need more ( i have 300)
Fbut if you want speed use batch size 7
Ano i want quality
Fmore better
Aso tier 1 ok thanks
Fdefinitely
Fyes
Lrepeats the same? 150-200 or i need to lower?
Abtw doctor for multitalk very good and stable results gives the default t2v lighxv2 rank 32
