Int object not iterable? (Python) (URGENT, NEEDED BY TONIGHT) : This is really urgent and I need this tomorrow, I cant seem to find a solution anywhere, I have a script that runs a facial recognition script, but for some reason its telling me this exact error:
----------
         File "box.py",line 98, in <module>
           label,confidence = model.predict(crop)
    TypeError: 'int' object is not iterable


----------
My code thats actually important to  the problem:


----------
    import cv2

    #Creates model to be the facerecognizer
    model = cv2.face.createEigenFaceRecognizer()
    
    #Defines the model as a training image taken previously
    model.load(config.TRAINING_FILE)

    #Initializes the camera as camera
    camera = config.get_camera()

    #Takes a picture using the camera
    image = camera.read()

    #Converts to grayscale
    image = cv2.cvtColor(image, cv2.COLOR_RGB2GRAY)

    #Results if it found a face
    result = face.detect_single(image)

    #Tells you to keep taking a picture until you have a face recognized
    if result is None:
            print 'Could not see face! Retake picture!'
            continue

     #gets dimensions of the face
     x,y,w,h = result
     
     #resizes the face
     crop = face.resize(face.crop(image, x, y, w, h))
   
     #Tests face against the previously taken model
     label, confidence = model.predict(crop) **<--- This is where the error is**

     #Im not 100% as to what this does, I got this part on the internet
     result = cv2.face.MinDistancePredictCollector()
     model.predict(crop)
     label = result.getLabel()
     confidence = result.getDist()


Thats basically it (Theres obviously some more code set up inside and between but it isnt important or relevant to the issue, at least I dont think, I need this urgently so please somebody respond quick, Im using Python 2.7 with opencv 3.1.0 on a raspbian raspberry pi 3 if you need that information
