Google Colab Open CV, Haar Cascade working error "!empty() in function 'detectMultiScale'"

Question

I am working on Google Colab, the files are on Google Drive.

here in this screenshot 2nd block of code runs fine, it is getting the image file from the drive and converting it to grayscale.
when importing and printing the cascade clasifier it is not giving any error which means it was also successfully imported from drive
**but i am getting the error: (-215:Assertion failed) !empty() in function 'detectMultiScale' **

full code

import cv2 as cv
import matplotlib.pyplot as plt
import numpy as np
from google.colab.patches import cv2_imshow

# connect colab to drive and get the files
from google.colab import drive
drive.mount('/content/drive')

img = cv.imread('/content/drive/My Drive/colab/faceRecProject/me.jpg')
gray = cv.cvtColor(img, cv.COLOR_BGR2GRAY)

haar_cascade = cv.CascadeClassifier('haar_face.xml') # loading the face detection classifier model
print(haar_cascade)

faces_rect = haar_cascade.detectMultiScale(gray,1.1,3)

what do you mean by another source? Not from the drive, what other source do I have. — rabeeh_ta, May 19 '22 at 08:03
Is that currently directory? Or you didn't specified which drive? — toyota Supra, May 19 '22 at 09:46
