被八阿哥气疯的一天
求大佬指点迷津
File "C:\Users\yuanfang\PycharmProjects\SystemBetter\recognize_service.py", line 21, in recognise_face
label, confidence = RECOGNIZER.predict(photo) # 识别器开始分析人脸图像
cv2.error: OpenCV(4.7.0) D:\a\opencv-python\opencv-python\opencv_contrib\modules\face\src\lbph_faces.cpp:406: error: (-5:Bad argument) This LBPH model is not computed yet. Did you call the train method? in function 'cv::face::LBPH::predict'

OpenCV库的LBPH模型不是已经训练好了的吗？仔细检查后发现程序中也调用了train（）进行训练，但为什么老是报这个错呢？
求求各位大佬，救救孩子吧
