- This is Extension for AUTOMATIC1111's Stable Diffusion Web UI
- Implementation GUI of [Merge Block Weighted] (https://note.com/kohya_ss/n/n9a485a066d5b) idea by kohya_ss
- change some part of script to adjust for AUTO1111, basic method is not changed.
-
2023/01/12: Add some function
- Save as half
- Save as safetensors
- Select of "Skip/Reset CKIP
position_ids
"
-
2022/12/25: Add new feature and new UI
- Go to
Extensions
tab on your web UI Install from URL
with this repo URL- Install
- Restart Web UI
- if checkpoint is updated, push
Reload Checkpoint
button to reload Dropdown choises.
-
Select Presets by Dropdown
You can manage presets on tsv file (tab separated file) at
extention/<this extension>/csv/preset.tsv
-
or Input at GUI Slider
-
"INxx" is input blocks. 12 blocks
-
"M00" is middle block. 1 block
-
"OUTxx" is output blocks. 12 blocks
-
You can write your weights in "Textbox" and "Apply block weight from text"
- Weights must have 25 values and comma separated
- set "base_alpha"
base_alpha | |
---|---|
0 | merged model uses (Text Encoder、Auto Encoder) 100% from model_A |
1 | marged model uses (Text Encoder、Auto Encoder) 100% from model_B |
Settings | |
---|---|
verbose console output | Check true, if want to see some additional info on CLI |
Allow overwrite output-model | Check true, if allow overwrite model file which has same name. |
- Merged output is saved in normal "Model" folder.
-
Settings about save
-
"Save as half" mean float16
-
"Save as safetensors". If you set your output file ext as
.safetensors
, automaticaly saved as safetensors with/without this setting.
-
- In this function, you can select treatment of
position_ids
value in CLIP. - Values in this key controls matching of your prompt and embeddings.
- I've try to found the cause of 'Some model ignore No.1 token(word)' problem, and write some report about that. ([調査] Smile Test: Elysium_Anime_V3 問題を調べる #3|bbcmc|note)
- Arenatemp already have spectation of inside of models, and published Extension to fix this CLIP key problem. See also,
- MBW is also affected by this problem, because some model may (potensialy) have this issue, and causes/transfer some trouble to merged result model.
Select | Effect |
---|---|
None | do nothing about key. normal merge |
Skip | Skip position_ids key to eject effect. Value of Model A used. |
Reset | Replace position_ids values to tensor([[range(77)]]) |

kohya_ss さんのテストを再現してみる
- Compare SD15 and WD13 / Stable Diffusion 1.5 と WD 1.3 の結果を見る
- ※元記事は SD14 を使用 (WD13はSD14ベース)

変化傾向は、
- bw-merge1 で、顔立ちがややアニメ化 (sd15-wd13-ws50と比較して)
- bw-merge2 で、ややリアル風(特に seed=3 の目が良い)
-
おおまかに見て、kohya_ss さんの結果と同様の方向性になった。実装は問題ないと判断する
