Question

我正在为我的深度学习项目编写代码，并且在运行面部检测时遇到错误。

我正在构建面部识别系统，但出现错误

NameError：未定义名称'x'

在运行代码时，但是我找不到这些问题的根源。

import numpy as np
import cv2

CascadeClassifier = cv2.CascadeClassifier(r'C:\Users\ESEC\Desktop\opencv\aditya\cascades\haarcascades\haarcascade_frontalface_alt2.xml')

cap = cv2.VideoCapture(0)


while(True):
    # Capture frame-by-frame
    ret, frame = cap.read()



    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    faces = CascadeClassifier.detectMultiScale(gray, scaleFactor=1.5, minNeighbors=5)

    for (x, y, w, h) in faces:
        print(x,y,w,h)
        roi_gray = gray[y:y+h, x:x+w]

        roi_color = gray[y:y+h, x:x+w]

        img_item = 'image.png'
        cv2.imwrite(img_item, roi_gray)
    # Our operations on the frame come here

    color = (255,0,0) #BGR 0=255

    stroke = 2


    end_cord_x = x + w

    end_cord_y = y + h

    cv2.rectangle(frame, (x, y), (end_cord_x, end_cord_y), color, stroke)

    # Display the resulting frame
    cv2.imshow('frame',frame)
    if cv2.waitKey(20) & 0xFF == ord('q'):
        break

     # When everything done, release the capture
     cap.release()
     cv2.destroyAllWindows()

它应该运行平稳并且应该在脸部周围显示矩形，但是出现以下错误。

File "camera-test.py", line 34, in <module>
end_cord_x = x + w
NameError: name 'x' is not defined

运行代码时出现未定义的错误
