IndexError: list index out of range

[aniiketdongare07]

Been trying to solve this error but have no luck, tried all whatever was said in https://www.hackster.io/mjrobot/real-time-face-recognition-an-end-to-end-project-a10826 comment section, but same error. My code is :

`'''' Real Time Face Recogition ==> Each face stored on dataset/ dir, should have a unique numeric integer ID as 1, 2, 3, etc
==> LBPH computed model (trained faces) should be on trainer/ dir Based on original code by Anirban Kar: https://github.com/thecodacus/Face-Recognition

import cv2 import numpy as np import os

recognizer = cv2.face.LBPHFaceRecognizer_create() recognizer.read('trainer/trainer.yml') cascadePath = "haarcascade_frontalface_default.xml" faceCascade = cv2.CascadeClassifier(cascadePath);

font = cv2.FONT_HERSHEY_SIMPLEX

iniciate id counter

id = 0

names related to ids: example ==> Marcelo: id=1, etc

names = ["PhotoAni", "Aniket", "Mum", "Dad"]

Initialize and start realtime video capture

cam = cv2.VideoCapture(0) cam.set(3, 640) # set video widht cam.set(4, 480) # set video height

Define min window size to be recognized as a face

minW = 0.1cam.get(3) minH = 0.1cam.get(4)

while True:

ret, img =cam.read()
#img = cv2.flip(img, -1) # Flip vertically

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

faces = faceCascade.detectMultiScale( 
    gray,
    scaleFactor = 1.2,
    minNeighbors = 5,
    minSize = (int(minW), int(minH)),
   )

for(x,y,w,h) in faces:

    cv2.rectangle(img, (x,y), (x+w,y+h), (0,255,0), 2)

    id, confidence = recognizer.predict(gray[y:y+h,x:x+w])

    # Check if confidence is less them 100 ==> "0" is perfect match 
    if (confidence < 100):
        id = names[id]
        confidence = "  {0}%".format(round(100 - confidence))
    else:
        id = "unknown"
        confidence = "  {0}%".format(round(100 - confidence))

    cv2.putText(img, str(id), (x+5,y-5), font, 1, (255,255,255), 2)
    cv2.putText(img, str(confidence), (x+5,y+h-5), font, 1, (255,255,0), 1)  

cv2.imshow('camera',img) 

k = cv2.waitKey(10) & 0xff # Press 'ESC' for exiting video
if k == 27:
    break

Do a bit of cleanup

print("\n [INFO] Exiting Program and cleanup stuff") cam.release() cv2.destroyAllWindows() `
