2017-03-09 23:51:31 -0500 asked a question roslaunch twist_mux occur process has died

Hi sir,

I run ros in raspberry pi 3, the os is ubuntu-mate-16.04.2, ros version is kinetic.

After i install twist_mux, i run roslaunch twist_mux twist_mux.launch, it occurs process has died.

The log is following

[roslaunch.pmon][INFO] 2017-03-10 10:04:38,221: ProcessMonitor.register[twist_mux-2]

log file: /home/ubuntu/.ros/log/e8e28cc0-0535-11e7-99c1-b827eb3a925d/twist_mux-2*.log

I can't find twist_mux-2*.log.

But if i get source code and catkin_make, i can run twist_mux well.

And in other computer, like desktop, up-board, indigo on raspberry pi 2 also can run well.

Thanks.
