Hi Kangjin-
Looking at your code, everything is correct. You just forgot to create and
run the gen_number.py script as described in the third part of the tutorial
series.

server is waiting for data from the random number generator before it can
compute the average requested by the goal from the action client.

for the question. In the future please send your questions to
ros-users@code.ros.org so that everyone can benefit from your questions :)
The ROS community is very helpful and quick to answer questions.
