我正在尝试使用mac上的opencv进行面部识别,但不断收到此错误消息:
The function is not implemented. Rebuild the library with
Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian,
install libgtk2.0-dev and pkg-config, then re-run cmake or configure
script in function cvShowImage
我在mac osx上使用python并使用pip安装opencv。有没有人有过这种错误的经验,如果有,你是怎么解决的?
这是我的代码:
import numpy as np
import cv2
face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml')
eye_cascade = cv2.CascadeClassifier('haarcascade_eye.xml')
img = cv2.imread('/william.jpg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
faces = face_cascade.detectMultiScale(gray, 1.3, 5)
for (x, y, w, h) in faces:
img = cv2.rectangle(img, (x, y), (x+w, y+h), (255, 0, 0), 2)
roi_gray = gray[y:y+h, x:x+w]
roi_color = img[y:y+h, x:x+w]
eyes = eye_cascade.detectMultiScale(roi_gray)
for (ex, ey, ew, eh) in eyes:
cv2.rectangle(roi_color, (ex, ey), (ex+ew, ey+eh), (0, 255, 0), 2)
cv2.imshow('img', img)
cv2.waitKey(0)
cv2.destroyAllWindows()
答案 0 :(得分:0)
尝试以下步骤:
在安装opencv lib-files的地方验证DIR
print(cv2.getBuildInformation())
重新编译via instruction on linux(或在官方网站上重新编译)
