haarcascades error: (-215:Assertion failed) !empty() in function 'cv::CascadeClassifier::detectMultiScale'

[ZaccD0099]

Continue getting this error for drone face tracking course, I think it is due to the file. Any ideas?

My Code:

import cv2 import numpy as np

def findFace(img): faceCascade = cv2.CascadeClassifier('Resources/haarcascade_frontalface_default.xml') imgGray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) faces = faceCascade.detectMultiScale(imgGray,1.1,8)

myFaceListC = []
myFaceListArea = []

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

cap = cv2.VideoCapture(0)

while True: _, img = cap.read() findFace(img) cv2.imshow("Output",img) cv2.waitKey(1)

Error:
