我正在尝试使用cv2在python-3.6中学习人脸检测。OpenCV错误:Python中的未知错误代码-49
我遵循书中给出的src。
我已经通过PIP安装的OpenCV的Python(3.2.0)
.XML和.jpg文件都与Python代码相同的路径。
from numpy import *
import cv2
face_cascade = cv2.CascadeClassifier("D:\\Python\\FaceDetec\\lbpcascade_frontalface.xml")
img = cv2.imread("z1.jpg")
gary = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
faces = face_cascade.detectMultiScale(gray, 1.2, 3)
for(x, y, w, h) in faces:
img2 = cv2.rectangle(img, (x, y), (x+w, y+h), (255, 255, 255), 2)
roi_gray = gray[y:y+h, x:x+w]
roi_color = img[y:y+h, x:x+w]
cv2.imshow("img", img)
cv2.waitKey(0)
cv2.destroyAllWindows()
cv2.imwrite("z1.head.jpg", img)
我收到一个错误,我找不到任何地方。

请在此帮助我。谢谢。
lbpcascade_frontalface.xml从https://github.com/opencv/opencv/tree/master/data/lbpcascades –
下载对不起,我罚的问题。我从http://opencv.org/ 更改.xml一切正常。谢谢 –
