Compatibility issue (cv2.cv.CV_HAAR_SCALE_IMAGE) about opencv-python

[kkk333]

import cv2
import sys

cascPath = "haarcascade_frontalface_default.xml"
faceCascade = cv2.CascadeClassifier(cascPath)

video_capture = cv2.VideoCapture(0)

while True:
# Capture frame-by-frame
ret, frame = video_capture.read()

gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

faces = faceCascade.detectMultiScale(
    gray,
    scaleFactor=1.1,
    minNeighbors=5,
    minSize=(30, 30),
    flags=cv2.CASCADE_SCALE_IMAGE
)

# Draw a rectangle around the faces
for (x, y, w, h) in faces:
    cv2.rectangle(frame, (x, y), (x+w, y+h), (0, 255, 0), 2)

# Display the resulting frame
cv2.imshow('Video', frame)

if cv2.waitKey(1) & 0xFF == ord('q'):
    break

When everything is done, release the capture

video_capture.release()
cv2.destroyAllWindows()

it showed me an error again:

File "C:/Users/KRK/PycharmProjects/CNN/webcamwithfunctionneu.py", line 20, in
flags=cv2.CASCADE_SCALE_IMAGE
cv2.error: C:\projects\opencv-python\opencv\modules\objdetect\src\cascadedetect.cpp:1698: error: (-215) !empty() in function cv::CascadeClassifier::detectMultiScale

Fixed error.

Thank you so much.

I'm with the same problem as @kkk333

Same here as @kkk333

[esitharth]

@lcjr86 and @kkk333 Check the file path in cv2.CascadeClassifier("/filepath/haarcascade.xml"). Correcting the right file path solved this issue for me.

@esitharth How to check the file path?
