WWX-alpha commented 8 months ago

If rospy and RKNNLite are imported at same time, follow error occurs:

my code:

#!/usr/bin/env python3
#coding = utf-8

import rospy
import numpy as np
import cv2
from rknnlite.api import RKNNLite

if __name__ == '__main__':
    rospy.init_node('detect_node')

It looks like RKNN overrides ros logging. Try to launch detection in a separate process may help you.

maybe just init_node first and then import RKNNLite. but I used multiprossing to seprate them in two threads, one for ROS and another for RKNN, then use pipe to communicate.
