I am trying to implement face recognition algorithm on PYNQ-Z1 platform; v2.4 PYNQ image. The code is bellow
from pynq import Overlay
Overlay(“base.bit”).download()
from pynq import Overlay
from pynq.lib.video import *
base = Overlay(‘base.bit’)
#hdmi_in = base.video.hdmi_in
hdmi_out = base.video.hdmi_out
Mode = VideoMode(640,480,24)
hdmi_out = base.video.hdmi_out
hdmi_out.configure(Mode,PIXEL_BGR)
hdmi_out.start()
monitor (output) frame buffer size
frame_out_w = 1280 #1920 800 1024 1280
frame_out_h = 1024 #1080 600 768 720
camera (input) configuration
frame_in_w = 640
frame_in_h = 480
import cv2
import numpy as np
recognizer = cv2.face.LBPHFaceRecognizer_create()
recognizer.read(‘trainer/trainer.yml’)
cascadePath = “haarcascade_frontalface_default.xml”
multiple cascades: opencv/data/haarcascades at master · opencv/opencv · GitHub
faceCascade = cv2.CascadeClassifier(cascadePath);
font = cv2.FONT_HERSHEY_SIMPLEX
#iniciate id counter
id = 0
names related to ids: example ==> Marcelo: id=1, etc
names = [‘None’, ‘X’, ‘Y’, ‘Z’, ‘W’]
Initialize and start realtime video capture
videoIn = cv2.VideoCapture(0)
videoIn.set(cv2.CAP_PROP_FRAME_WIDTH, frame_in_w);
videoIn.set(cv2.CAP_PROP_FRAME_HEIGHT, frame_in_h);
Define min window size to be recognized as a face
minW = 0.1videoIn.get(3)
minH = 0.1videoIn.get(4)
print("capture device is open: " + str(videoIn.isOpened()))
I get this message
AttributeError Traceback (most recent call last)

----> 5 recognizer = cv2.face.LBPHFaceRecognizer_create()
6 recognizer.read(‘trainer/trainer.yml’)
7 cascadePath = “haarcascade_frontalface_default.xml”
AttributeError: module ‘cv2.face’ has no attribute ‘LBPHFaceRecognizer_create’
I searched on the web, some suggested installing opencv-contrib-python :
pip uninstall opencv-contrib-python
pip install opencv-contrib-python
I got this :
root@pynq:/home/xilinx# sudo pip3 install opencv-contrib-python
Collecting opencv-contrib-python
Could not find a version that satisfies the requirement opencv-contrib-python (from versions: )
No matching distribution found for opencv-contrib-python

Any help ?
