Attribute error while using opencv for face recognition <p>I am teaching myself how to use openCV by writing a simple face recognition program I found on youtube. I have installed opencv version 2 as well as numpy 1.8.0. I am using python2.7.</p> <p>I copyed this code exactly how it was done in the video and article links below, yet I keep getting errors. AttributeError: 'module' object has no attribute 'cv' What am I doing wrong?</p> <p>Here is the code I'm using.</p> <pre><code>import cv2 import sys # Get user supplied values imagePath = sys.argv[1] cascPath = sys.argv[2] # Create the haar cascade faceCascade = cv2.CascadeClassifier(cascPath) # Read the image image = cv2.imread(imagePath) gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) # Detect faces in the image faces = (faceCascade.detectMultiScale( gray, scaleFactor=1.1, minNeighbors=5, minSize=(30, 30), flags = cv2.cv.CV_HAAR_SCALE_IMAGE) ) print "Found {0} faces!".format(len(faces)) # Draw a rectangle around the faces for (x, y, w, h) in faces: cv2.rectangle(image, (x, y), (x+w, y+h), (0, 255, 0), 2) cv2.imshow("Faces found", image) cv2.waitKey(0) </code></pre> <p><a href="https://www.youtube.com/watch?v=IiMIKKOfjqE" rel="nofollow">https://www.youtube.com/watch?v=IiMIKKOfjqE</a></p> <p><a href="https://realpython.com/blog/python/face-recognition-with-python/" rel="nofollow">https://realpython.com/blog/python/face-recognition-with-python/</a></p>
