Face is not getting enclosed in the square shape

#1

I have written the same code as that of you , also the web camera has started but the square shape is not getting i
mport cv2
cap = cv2.VideoCapture(0)
face_cascade = cv2.CascadeClassifier(“haarcascade_frontalface_alt.xml”)
while True:
ret,frame = cap.read()
c_fr = cv2.cvtColor(frame,cv2.COLOR_BGR2GRAY)

if ret == False:
    continue

faces = face_cascade.detectMultiScale(frame,1.3,5)

for (x,y,w,h) in faces:
    cv2.rectangle(c_fr,(x,y),(x+w,y+h),(255,0,0),2)

cv2.imshow("Video frame",frame)

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

cap.release()
cv2.destroyAllWindows()

Is the path to your file correct?
Check this first
If the code is as it is, this fix should work, if it does not raise a doubt again
