I'm trying to get the solution Pi-camera with opencv by the problem.Solvers, but get a AttributeError: 'PiRGBArray' object has no attribute 'shape' Thanks for the help.

frame = imutils.resize(frame, width=450) File "/usr/local/lib/python3.5/dist-packages/imutils/convenience.py", line 69, in resize (h, w) = image.shape[:2] AttributeError: 'PiRGBArray' object has no attribute 'shape' That's a problem

from scipy.spatial import distance
from imutils import face_utils
from picamera.array import PiRGBArray
from picamera import PiCamera
import numpy as np
import imutils
import dlib
import cv2
import time



camera = PiCamera()
camera.resolution = (640, 480)
camera.framerate = 32
rawCapture = PiRGBArray(camera, size=(640, 480))


def eye_aspect_ratio(eye):
    A = distance.euclidean(eye[1], eye[5])
    B = distance.euclidean(eye[2], eye[4])
    C = distance.euclidean(eye[0], eye[3])
    ear = (A + B / (2.0 * C)
    return ear

thresh = 0.22
threshs = 0.18
frame_check = 120
detect = dlib.get_frontal_face_detector()
predict = dlib.shape_predictor("shape_predictor_68_face_landmarks.dat")

(lStart, lEnd) = face_utils.FACIAL_LANDMARKS_68_IDXS["left_eye"]
(rStart, rEnd) = face_utils.FACIAL_LANDMARKS_68_IDXS["right_eye"]

flag=0

while True:
    for frame in camera.capture_continuous(rawCapture,format="bgr", use_video_port=True):

        subjects = detect(gray, 0

        for subject in subjects:

                if ear > threshs:
                    flag += 1
                    if flag >= frame_check:

        else:
            flag = 0
    cv2.imshow("Frame", frame)
    key = cv2.waitKey(1) & 0xFF

    raw.truncate(0)

    Please don't post images of code or errors - they are impossible to run or search through. Kindly click `edit` under your question and update it. Thank you. – Mark Setchell Nov 15 '18 at 19:19
  • I'm sorry, I resolved @MarkSetchell – 1cesN0brown Nov 15 '18 at 19:39
  • Surely you had to `import` some modules? Please make sure you provide a **Minimum, Complete and Verifiable Example** as required by Stack Overflow rules https://stackoverflow.com/help/mcve – Mark Setchell Nov 15 '18 at 19:44
  • I understand already, I am a new user and thank you for the advice. And you have a solution code Of me? @MarkSetchell – 1cesN0brown Nov 15 '18 at 20:00
  • I am guessing that the PiRGBArray/frame that you are passing to `imutils.resize()` is not a Numpy array. There is a lot of very distracting stuff in your code about eyes, contours, playing music... you need to work a bit more on the **Minimal** aspect of your code. Sorry to be picky but if you want folks to help you, it's generally a good idea to make it easy for them. – Mark Setchell Nov 15 '18 at 20:13
  • Thank you very much, I will try. @MarkSetchell – 1cesN0brown Nov 16 '18 at 19:00
