importerror:no module named basic.msg
Hi, I have a problem on creating msg and writing publisher(python). when I creating msg and 'catkin_make', there is no error. But when I try to run the python node (rosrun baisc message_publisher.py), I got a error:
Traceback (most recent call last):
File "/home/hywel/catkin_ws/src/basic/scripts/message_publisher2.py", line 4, in <module>
from basic.msg import Complex2
