ERROR: cannot launch node of type [trafficlight_recognizer/region_tlr_ssd]: Cannot locate node of type [region_tlr_ssd] in package [trafficlight_recognizer]. Make sure file exists in package path and permission is set to executable (chmod +x)

Do you see the trafficlight_recognizer package on the ROS package path?

To check this run echo $ROS_PACKAGE_PATH in a terminal and inspect it.

EDIT: O wait, it looks like it already finds the package. IDK what i was thinking lol
