AI 生圖 Stable Diffusion web UI 筆記
Stable Diffusion web UI 安裝篇
系統需求
我是在 Windows 11 的環境下使用的,沒有外接顯示卡,使用 CPU 內顯
CPU 是 AMD Ryzen™ 7 PRO 4750G
內顯的 vram 4GB
記憶體是2條16GB 3200 MHz
硬碟建議預留30GB以上空間 (安裝一種模型可能就 7~8 GB了)
安裝步驟
-
安裝 Python 3.10
從 Microsoft Store (Microsoft市集) 直接下載安裝,用這個的原因是會設定 PATH 路徑 的系統變數

指令列安裝 Stable Diffusion web UI,共四個指令
先到要安裝的路徑,在資料夾空白處按右鍵在終端中開啟(cmd) 或是 powershell ,啟動指令列視窗,依序輸入下列的指令,這些指令分別是
- git 指令是從 github 網站上將主程式複製一份到自己電腦目前位置
- 進入主程式資料夾
- 啟動子模組
- 更新子模處
安裝完後,到資料夾開啟 webui.bat
第一次執行會很長,執行畫面長這樣

其他具體安裝東西參考官方 github 說明
https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Install-and-Run-on-AMD-GPUs
因為我是用內顯算圖,所以記憶體比較缺乏,需要手動用記事本開啟開啟 webui-user.bat 這個檔案並進行修改,將原本的
set COMMANDLINE_ARGS=
後面追加一些指令,降低效能但可以讓運作正常,這些是我加的
AI算圖中的樣子
command line 視窗不要關 (可以縮到背景)

故障的情形
終端視窗最後一行會顯示 Runtime Error
通常是數值調太高(寬高太高 steps 太多、批次數量太多),就有可能會故障,這時候改低一些,重新生成就好

使用的情形或問題
-
內顯算一張 512x512,steps 20 的大概要150秒(2分半)
-
如果算出來圖都是全黑,試試看更新顯示卡驅動,我更新到最新的才正常
-
有時候亂數種子算出來就是會出現一些會降低 san 值的東西,換一組種子就好,建議一次至少4張去算,失敗幾張就算了
