Traceback (most recent call last):
File "E:\shixundaima\pythonOpencv\face_4.py", line 46, in
faces = faceCascade.detectMultiScale( gray,scaleFactor= 1.1, minNeighbors=8, minSize=(55, 55),flags=cv2.CASCADE_SCALE_IMAGE)
cv2.error: OpenCV(4.4.0) C:\Users\appveyor\AppData\Local\Temp\1\pip-req-build-95hbg2jt\opencv\modules\objdetect\src\cascadedetect.cpp:1689: error: (-215:Assertion failed) !empty() in function 'cv::CascadeClassifier::detectMultiScale'
