Hi @spike

Are you trying to parse the output from the serial? That will be a bit messy you can just use our SDK:

See the relevant example:

github.com

edgeimpulse/linux-sdk-python/blob/master/examples/image/classify-image.py

#!/usr/bin/env python

import device_patches       # Device specific patches for Jetson Nano (needs to be before importing cv2)

import cv2
import os
import sys, getopt
import numpy as np
from edge_impulse_linux.image import ImageImpulseRunner

runner = None

def help():
    print('python classify-image.py <path_to_model.eim> <path_to_image.jpg>')

def main(argv):
    try:
        opts, args = getopt.getopt(argv, "h", ["--help"])
    except getopt.GetoptError:
        help()
