cv2 errors when calling client on raspberry pi os #1

Hi, I tried running the Client on the raspberry pi driving the robot, but I ran into an issue launching the client:

pi@raspberrypi:~/Freenove_Robot_Dog_Kit_for_Raspberry_Pi/Code/Client $ sudo python Main.py
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
Traceback (most recent call last):
  File "Main.py", line 1072, in <module>
    myshow=MyWindow()
  File "Main.py", line 27, in __init__
    self.client=Client()
  File "/home/pi/Freenove_Robot_Dog_Kit_for_Raspberry_Pi/Code/Client/Client.py", line 16, in __init__
    self.face = Face()
  File "/home/pi/Freenove_Robot_Dog_Kit_for_Raspberry_Pi/Code/Client/Face.py", line 7, in __init__
    self.recognizer = cv2.face.LBPHFaceRecognizer_create()
AttributeError: module 'cv2.face' has no attribute 'LBPHFaceRecognizer_create'

I changed line 7 to self.recognizer = cv2.face.createLBPHFaceRecognizer() but then ran into this error:

pi@raspberrypi:~/Freenove_Robot_Dog_Kit_for_Raspberry_Pi/Code/Client $ sudo python Main.py 
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'

    self.recognizer.read('Face/face.yml')
AttributeError: 'cv2.face_LBPHFaceRecognizer' object has no attribute 'read'

To fix that I did changed line 8 to: self.recognizer.load('Face/face.yml')
