ImportError: No module named package.srv
I tried to get answer for my question by following the 2 web site bellow : http://wiki.ros.org/ROS/Tutorials/Mul... and http://wiki.ros.org/ROS/NetworkSetup My work : i'm trying to communicate between 2 machines with custom messages ( client/server ). In PC1: i create : - a catkin package named "pc1" . - msg/Num.msg inside pc1. - scripts/client.py
In PC2: i create : - a catkin package named "pc2" . - srv/AddTwoInts.srv inside pc2. - scripts/server.py
pc1/scripts/client.py:
#!/usr/bin/env python
import rospy
import sys
from pc2.srv import *
def add_two_ints_client(x, y):
rospy.wait_for_service('add_two_ints')
try:
add_two_ints = rospy.ServiceProxy('add_two_ints', AddTwoInts)
resp1 = add_two_ints(x, y)
return resp1.sum
except rospy.ServiceException, e:
print "Service call failed: %s"%e
def usage():
return "%s [x y]"%sys.argv[0]
if __name__ == "__main__":
if len(sys.argv) == 3:
x = int(sys.argv[1])
y = int(sys.argv[2])
else:
print usage()
sys.exit(1)
print "Requesting %s+%s"%(x, y)
print "%s + %s = %s"%(x, y, add_two_ints_client(x, y))
pc2/scripts/server.py:
#!/usr/bin/env python
from pc2.srv import *
import rospy
def handle_add_two_ints(req):
print "Returning [%s + %s = %s]"%(req.a, req.b, (req.a + req.b))
return AddTwoIntsResponse(req.a + req.b)
def add_two_ints_server():
rospy.init_node('add_two_ints_server')
s = rospy.Service('add_two_ints', AddTwoInts, handle_add_two_ints)
print "Ready to add two ints."
rospy.spin()
if __name__ == "__main__":
add_two_ints_server()
i executed in pc2 ssh command with $ roscore and $ rosrun pc2 server.py in pc1 , i executed ssh and export commends but when i executed $rosrun pc1 client.py i faced this ERROR: importError: No module named pc1.srv
