Pthread set sched policy failed
I am using ROS to control the Unitree A1,
But when I run the roslaunch command, this error keeps showing.
process[node_lcm_server_running-1]: started with pid [919816] Error: Pthread set sched policy failed. process[unitree_base_node-2]: started with pid [919817] [node_lcm_server_running-1] process has died [pid 919816, exit code 254, cmd /home/user/catkin_ws/devel/lib/unitree_base/lcm_server_running_node a1 highlevel __name:=node_lcm_server_running __log:=/home/user/.ros/log/114485b2-0e2f-11ed-9046-4b1a6b229934/node_lcm_server_running-1.log].
I've read the second log file while the first log isn't even made,
Error: Lock memory failed.
I think the error message is related to the first error message which is exit 254: pthread set sched policy failed.
Is there anybody who have experienced this error or the one similar to this?
Thanks in advance!
