basically I have the coude as in the solution
when doing a roslaunch ./init_particles_caller.launch it failed with
xception in thread Thread-4 (most likely raised during interpreter shutdown): Traceback (most recent call last): File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner File "/usr/lib/python2.7/threading.py", line 754, in run File "/opt/ros/kinetic/lib/python2.7/dist-packages/rospy/impl/tcpros_base.py", line 154, in run <type 'exceptions.AttributeError'>: 'NoneType' object has no attribute 'timeout' [service_client-1] process has finished cleanly log file: /home/user/.ros/log/74e1d3e2-8acc-11ea-a670-0af5caab061a/service_client-1*.log all processes on machine have died, roslaunch will exit
and of couse there is nothing in RVIZ
Is PoseArray the right plugin for particle cloud ?
what can be the issue here ?
