# Merge Block Weighted - GUI
|
||
|
||
- This is Extension for [AUTOMATIC1111's Stable Diffusion Web UI](https://github.com/AUTOMATIC1111/stable-diffusion-webui)
|
||
- 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.
|
||
|
||
|
||
|
||
## How to Install
|
||
|
||
- Go to `Extensions` tab on your web UI
|
||
- `Install from URL` with this repo URL
|
||
- Install
|
||
- Restart Web UI
|
||
|
||
## How to use
|
||
|
||
### Select `model_A` and `model_B`, and input `Output model name`
|
||
|
||
|
||
|
||
- if checkpoint is updated, push `Reload Checkpoint` button to reload Dropdown choises.
|
||
|
||
### Set merge ratio for each block of U-Net
|
||
|
||
- 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
|
||
|
||
### Setting values
|
||
|
||
|
||
|
||
- 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` |
|
||
|
||
### Other settings
|
||
|
||
| 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.
|
||
|
||
## Other function
|
||
|
||
### Save Merge Log
|
||
|
||
- save log about operated merge, as below,
|
||
|
||
|
||
- log is saved at `extension/<this extension>/csv/history.tsv`
|
||
|
||
## Sample/Example
|
||
|
||
- 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)
|
||
- see also [Stable DiffusionのモデルをU-Netの深さに応じて比率を変えてマージする｜Kohya S.｜note](https://note.com/kohya_ss/n/n9a485a066d5b)
|
||
|
||
- 準備する/マージして作るモデルは、以下の通り / Prepare models as below,
|
||
|
||
| Model Name | |
|
||
| --------------- | ----------------------------------------------------------------- |
|
||
| sd-v1.5-pruned | Stable Diffusion v1.5 |
|
||
| wd-v1.3-float32 | wd v1.3-float32 |
|
||
| SD15-WD13-ws50 | 通常マージしたもの<br>SD15 + WD13, 0.5 # Weighted sum 0.5 |

Negative prompt: lowres, bad anatomy, bad hands, error, missing fingers, cropped, worst quality, low quality, normal quality, jpeg artifacts, blurry

|
||
|
||
### result (x/y)
|
||
|
||
|
||
|
||
- 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
