Error found when running nvblox quick start example

Robotics & Edge Computing Robotics - Isaac Isaac ROS

I’m currently running on my Jetson-orin-agx with ubuntu22.04 and Jetpack 6.0. After I built the nvblox package and plugged in my realsensor, I tried the following command

 $ ros2 launch nvblox_examples_bringup realsense_example.launch.py \
mode:=people

And I got

[component_container_mt-2] ERROR: NvDsTritonServerInit failed to get global triton instance

But if I run

 $ ros2 launch nvblox_examples_bringup realsense_example.launch.py \
mode:=dynamic

There won’t be any errors.

Hi,
Do you mean you fail to run this:
Nvblox — isaac_ros_docs documentation

Yes. We reinstall the whole environment again, and it works. Maybe we just lost some steps.
