remote launch

edit

I want to remote run some nodes, below was my coding

<launch>
  <!-- This assumes roscore is running on other machine -->
  <env name="ROS_MASTER_URI" value="http://robot1:11311"/>

  <machine name="robot1" address="192.168.0.101" password="123456" env-loader="/home/robot1/catkin_ws/test.sh" user="robot1"/>


  <group ns="robot1">
    <node machine="robot1" pkg="rqt_graph" type="rqt_graph"  name="rqt_graph">
    </node>
  </group>

</launch>

the sh file as below:

#!/bin/bash

export ROS_WS=/home/robot1/catkin_ws
export PATH=$ROS_ROOT/bin:$PATH
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:$ROS_WS
exec "$@"

Then its show the error like that
