I hope you are talking about capture part and train part in MMM-Facial-recognition-Tools. It works fine but in mmm-facial recognition folder there is a config .py file which created the problem throwing config=jsonl.oads(sys arg…) // I do not remmeber.
I just figured out few hours ago.
TRy this code

#!/usr/bin/python

coding: utf8

def to_node(type, message):
print(json.dumps({type: message}))
sys.stdout.flush()

_platform = platform.uname()[4]
path_to_file = os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe())))

Size (in pixels) to resize images for training and prediction.

Don’t change this unless you also change the size of the training images.

FACE_WIDTH = 92
FACE_HEIGHT = 112

Face detection cascade classifier configuration.

You don’t need to modify this unless you know what you’re doing.

See: http://docs.opencv.org/modules/objdetect/doc/cascade_classification.html

HAAR_FACES = path_to_file + ‘/haarcascade_frontalface.xml’
HAAR_SCALE_FACTOR = 1.3
HAAR_MIN_NEIGHBORS = 4
HAAR_MIN_SIZE = (30, 30)

#CONFIG = json.loads(sys.argv[1]);
CONFIG={

    "recognitionAlgorithm": 1,

}

def get(key):
return CONFIG[key]

def get_camera():
to_node(“status”, “-” * 20)
try:
if get(“useUSBCam”) == False:
#import picam
from imutils.video import VideoStream
to_node(“status”, “PiCam Enabled…”)
vs = VideoStream(usePiCamera=True,resolution=(640,480)).start()
#cam = picam.OpenCVCapture()
#cam.start()
return vs
else:
raise Exception
except Exception:
import webcam
to_node(“status”, “Webcam ausgewählt…”)
return webcam.OpenCVCapture(device_id=0)
to_node(“status”, “-” * 20)

replace the config.py code with above code.
I was able to fix the error with this. Hope it helps!
