cv2级联有问题

Question

这是我的代码：

import cv2 as c

face_cascade = c.CascadeClassifier(r"haracascade_frontalface.xml")
img  = c.imread(r"D:\cODE\Python_Only\CV2\Files\photo.jpg" )
grey_image = c.cvtColor(img , c.COLOR_BGR2GRAY)

faces = face_cascade.detectMultiScale(
    grey_image ,
    scaleFactor = 1.05,
    minNeighbors = 5
)

print(faces)

错误：

Traceback (most recent call last):
File "d:\cODE\Face_Detector.py", line 8, in \<module\>
faces = face_cascade.detectMultiScale(
cv2.error: OpenCV(4.5.5) D:\a\opencv-python\opencv-python\opencv\modules\objdetect\src\cascadedetect.cpp:1689: error: (-215:Assertion failed) !empty() in function 'cv::CascadeClassifier::detectMultiScale'

我不知道下一步该怎么做，我现在还是个初学者！

Answer 1

就这么办=

Please try absolute path for c.CascadeClassifier(r"haracascade_frontalface.xml")
