Rosnode runs with root access but not as a normal user

edit

Hi, I am using ROS Kinetic with a Nvidia TX2 board. I have a rosnode performing detection using faster rcnn framework on a camera feed. When I run it as a normal user using the command:

rosrun os_node os_cv_core 0 0 0 0 0 0 0 1 10 0

it throws the following error:

frcnn() running ...

Aborted (core dumped)

However, the node runs fine if I run it after entering root mode. How do I run this command as a regular user (using sudo does not work, I get the error saying sudo: rosrun: command not found)?

Edit: I asked the same question on Nvidia forums earlier but the solution posted there hasn't worked.

Thanks.
