inconsistent namespace redefinitions for xmlns:xacro:

I am running tumsimulator in ros kinetic ubuntu 16.04 when i run $ roslaunch cvgsimgazebo ardronetestworld.launch

i get the following warning,

xacro: Traditional processing is deprecated. Switch to --inorder processing! To check for compatibility of your document, use option --check-order. For more infos, see http://wiki.ros.org/xacro#Processing_... inconsistent namespace redefinitions for xmlns:xacro: old: http://playerstage.sourceforge.net/ga... new: http://ros.org/wiki/xacro (/home/dyana/catkinmake/src/cvgsimgazebo/urdf/quadrotorbase.urdf.xacro) inconsistent namespace redefinitions for xmlns:xacro: old: http://playerstage.sourceforge.net/ga... new: http://ros.org/wiki/xacro (/home/dyana/catkinmake/src/cvgsimgazebo/urdf/sensors/sonarsensor.urdf.xacro) inconsistent namespace redefinitions for xmlns:xacro: old: http://playerstage.sourceforge.net/ga... new: http://ros.org/wiki/xacro (/home/dyana/catkinmake/src/cvgsimgazebo/urdf/sensors/genericcamera.urdf.xacro) inconsistent namespace redefinitions for xmlns:xacro: old: http://playerstage.sourceforge.net/ga... new: http://ros.org/wiki/xacro (/home/dyana/catkinmake/src/cvgsimgazebo/urdf/sensors/genericcamera.urdf.xacro) redefining global property: pi when processing file: /home/dyana/catkinmake/src/cvgsimgazebo/urdf/quadrotorsensors.urdf.xacro xacro.py is deprecated; please use xacro instead

and when I $ rostopic echo /ardrone/front/camera_info WARNING: no messages received and simulated time is active. Is /clock being published?

I get the above message.

Is it because the camera xacro is not loaded properly? I did not have such issues while running with ros indigo. I get this issue after I moved to kinetic and gazebo7.14

How do i resolve this?
