Happy Meek (umamusume)

LoHa of Happy Meek (umamusume). Put LoHa file in your stable-diffusion-webui/models/lora folder and write LoRA notation in prompt to applying LoHa. <lora:your_loha_name:weight>

All of my works is free. If you'd like to support me, feel free to buy me a coffee. 👍

NOTICE

• After careful consideration, I decided not to produce LoRA of the characters below.

  • Otonashi Etsuko, Akasaka Misato, Hosoe Junko

• If anyone wants the characters above, I will consider making them.

• Except for the above, I will make the rest of the characters in Umamusume: Pretty Derby, unless there is a special notice.

• Something weird happened when training. If you interested in training, read comments on LoRA training info section.

LoRA training info

• trained on sd-scripts by kohya_ss.

  • LyCORIS by KohakuBlueleaf

  • Thank you all a lot!

• based on Animefull-pruned model

• 129 images consist of

  • 4x low quality 47 images

  • 8x medium quality 46 images

  • 16x high quality 36 images

  • => 1 epoch = 1132 images

• replaced character feature tags with happy meek \(umamusume\)

  • 1girl, red eyes, pink hair, simple background, solo, tail, braid, white hair, official alternate costume, long hair, alternate hairstyle, brown eyes, horse ears, purple eyes, horse girl, brown hair, blonde hair, alternate hair length, bangs, horse tail, blunt bangs, animal ears, pink eyes, yellow eyes, short hair, grey hair, light brown hair, ponytail, medium hair, seiun sky \(umamusume\), bob cut

  • I think these tags are the essentials of Happy Meek or

  • unnecessary for training because of duplication.

• resolution : 768x768 with aspect ratio bucketing.

• other training settings is included in training data or metadata of LoRA file.

• Yukino Bijin, Neo Universe, Zenno Rob Roy, Light Hello, Tracen Staff, Ines Fujin, Inari One and Tanino Gimlet were trained with learning rate of text encoder(TE) which has five times higher than Unet learning rate.

  • This is very interesting. Most of people uses TE lr as smaller than Unet lr. I did mistakes but got a good results. I don't know why these LoRA works. It may a clue to help to set proper learning rate.

  • I found this phenomenon in training of happy meek. During training, loss goes to nan. Happy meek has two tokens, so I think that higher TE learning rate with small tokens of trigger word make model boom.
