[ROS2 Dashing and Foxy] AttributeError: 'Argument' object has no attribute 'add_on_set_parameters_callback'

Test Env. Ubuntu 18.04, ROS2 Dashing, Jetson AGX Xaiver with Jetpack 4.5.1

 

 

ROS2 프로그래밍을 하다가 아래와 같은 오류를 만났다.

 

Traceback (most recent call last):
File "/home/robotv/colcon_ws/install/topic_service_action_rclpy_example/lib/topic_service_action_rclpy_example/argument", line 33, in <module>
sys.exit(load_entry_point('topic-service-action-rclpy-example', 'console_scripts', 'argument')())
File "/home/robotv/colcon_ws/build/topic_service_action_rclpy_example/topic_service_action_rclpy_example/arithmetic/argument.py", line 74, in main
argument = Argument()
File "/home/robotv/colcon_ws/build/topic_service_action_rclpy_example/topic_service_action_rclpy_example/arithmetic/argument.py", line 38, in __init__
self.add_on_set_parameters_callback(self.update_parameter)
AttributeError: 'Argument' object has no attribute 'add_on_set_parameters_callback'

 

기존 ROS2 Foxy의 튜토리얼을 따라하다 나온 것으로,

 

ROS2 Dashing에서는 'set_parameters_callback' attribute가

ROS2 Foxy에서 'add_on_set_parameters_callback'과 'remove_on_set_parameters_callback'으로 변경되었다.

 

 

따라서 사용 버전에 따라 적절한 attribute를 사용하면 된다.
