今天繼續閱讀杰克艾米粒這本超棒的 "Stable Diffusion：與杰克艾米立攜手專精 AI 繪圖" 來完善我的 SD 設定, 安裝 5 個推薦必裝外掛, 安裝方法與前一篇安裝中文化界面相同, 就是在 "Extensions" 頁籤的 "Install from URL" 子頁籤的 "URL for extension's git repository" 框中輸入外掛的 git 網址, 按 "Install" 鈕即可安裝, 參考 :
安裝網址可在此書的旗標服務專區取得 :
以下是安裝提示詞輔助工具 sd-webui-prompt-all-in-one 的紀錄, 不知道是不是我的電腦最早安裝了 Python 3.12 (SD Webui 用的是自帶的 Python 3.10) 造成干擾還是其他原因, 過程並不是像書中那麼順利.
https://github.com/Physton/sd-webui-prompt-all-in-one.git
然後按底下的 "Install(安裝)" 鈕 :
安裝完畢會在最底下出現 "Installed into C:\Users\USER\Downloads\sd.webui\webui\extensions\sd-webui-prompt-all-in-one. Use Installed tab to restart."
切到 "擴充功能"/"已安裝" 頁籤, 按 "更新並重新啟動使用者介面" 鈕 :
但是重新執行 run.bat 時慘劇發生了, 出現 "Python API call failed" 錯誤, 原因是找不到 "_cffi_backend" 模組 :

將上面訊息貼給 ChatGPT 求解, 它建議在 sd.webui 底下建一個 venv 虛擬環境安裝所需模組 :
pip install chardet execjs pathos boto3 aliyunsdkcore aliyunsdkalimt
但安裝完再次執行 run.bat 錯誤依舊, 因為虛擬環境會依據我電腦的 Python 版本 (3.12) 來安裝套件, 這跟 webui 自帶的 3.10 根本無關 (雖然是餿主意, 但也不能怪 AI, 因為它也不知道我的電腦環境). 所以只好問它如何移除 sd-webui-prompt-all-in-one 外掛恢復原狀, 建議如下 :
先到 sd.webui\webui\extensions 資料夾下刪除 sd-webui-prompt-all-in-one 這個目錄 :
然後往上跳一層到 sd.webui\webui 資料夾下刪除 config.json, ui-config.json 這兩個檔案 (啟動時會重新建立), 另外最好還要刪除 tmp 與 cache 這兩個暫存資料夾以清掉殘留快取 :
當然上面建立的 venv 虛擬環境資料夾也無用藥刪除 (先 deactivat 跳出).
但重新執行 run.bat 仍然出現上面一樣找不到 "_cffi_backend" 模組的錯誤訊息, 再次求教 ChatGPT, 它這回的解決方案中有一個是建議手動安裝 _cffi_backend 模組, 先切換到 webui 自帶的 Python 資料夾 sd.webui\system\python 下, 執行下列安裝指令 :
PS C:\Users\USER\Downloads\sd.webui\system\python> .\python.exe -m pip install --force-reinstall cffi
Collecting cffi
Downloading cffi-1.17.1-cp310-cp310-win_amd64.whl.metadata (1.6 kB)
Collecting pycparser (from cffi)
Using cached pycparser-2.22-py3-none-any.whl.metadata (943 bytes)
Downloading cffi-1.17.1-cp310-cp310-win_amd64.whl (181 kB)
Using cached pycparser-2.22-py3-none-any.whl (117 kB)
Installing collected packages: pycparser, cffi
Successfully installed cffi-1.17.1 pycparser-2.22
然後重新執行 run.bat 果然就恢復原狀了 :
但之前安裝的中文版擴充外掛設定被刪掉了 (外掛還在), 所以要重新設定.
系統恢復後我又再次安裝 sd-webui-prompt-all-in-one 外掛, 這次就順利完成了 :
可見頁面上增加了很多與 prompt 相關的按鈕.
經過這次波折也搞清楚如果 webui 自帶的 Python 缺少甚麼套件或模組, 原來是要到它底下的 python 目錄中去安裝.
