launch file is not working

[hsaleem1]

Hi there,

When I launched outdoor_waypoint_nav_sim using:
roslaunch outdoor_waypoint_nav outdoor_waypoint_nav_sim.launch

I got the following error:
No such file or directory: None None
while processing /home/user/catkin_ws/src/waypoint_nav/outdoor_waypoint_nav/launch/include/gazebo.launch:
while processing /home/user/catkin_ws/src/waypoint_nav/husky_simulator/husky_gazebo/launch/husky_empty_world.launch:
while processing /home/user/catkin_ws/src/waypoint_nav/husky_simulator/husky_gazebo/launch/spawn_husky.launch:
Invalid tag: Cannot load command parameter [robot_description]: command [/opt/ros/kinetic/share/xacro/xacro.py '' laser_enabled:=true ur5_enabled:=false kinect_enabled:=false --inorder ] returned with code [2].

Param xml is
The traceback for the exception was written to the log file

Can anyone please guide me to solve this problem?
Thanks.

@hsaleem1 I'm having the same issue as you did. Have you fixed that yet?
