我正在嘗試學習人臉檢測，我從GeeksforGeeks教程中獲得了這段代碼。但是，當我運行這兩個檔案之一時，它顯示錯誤AttributeError: module 'cv2' has no attribute 'LBPHFaceRecognizer_create'。我嘗試卸載 open cv，安裝pip install opencv-contrib-python以及重新安裝 open cv 并運行它。我目前正在運行 open cv2 4.5.5。本教程建議從cv2.face.LBPHFaceRecognizer_create()運行 cv2 中洗掉 '.face'，但是當我使用 .face 運行它時，它顯示模塊 'cv2' has no attribute 'face'。請有人幫我解決這個問題

uj5u.com熱心網友回復：
我認為您可能需要明確宣告“cv2.face”而不僅僅是“face ...”
model = cv2.face.LBPHFaceRecognizer_create()
在這樣做之前...您是否確認您安裝了包含 Face 模塊的 Opencv 版本？你可以這樣檢查：
import cv2
functions = dir(cv2)
for f in functions:
print (f)
如果沒有......像這樣安裝：
pip uninstall opencv-contrib-python
pip install opencv-contrib-python
