Error running apriltag example

Autonomous Machines Robotics - Isaac Isaac ROS

After flashing an Orin Nano using the SDK Manager, then following isaac_ros_apriltag — isaac_ros_docs documentation, I get this error. I also get a similar error when trying to follow the vslam example, with a different library (libcusolver.so.11).

I got same error on the Jetson NX. Please help! Thanks.

Hi @alistair7

I was testing on my orin nano, and I didn’t see any error.
Did you install all the necessary libraries from the SDK manager?

You can check if everything is installed with jtop at page 7

Hi @alistair7

Thank you for your screenshot.
You need Jetpack 5.1.2 for Isaac ROS to work. Please refer to the requirements page.

Best,

Failed to load library: Could not load library dlopen error: libnvToolsExt.so.1: cannot open shared object file: No such file or directory

I ran into this issue as well recently on JetPack 6.1. My issue was that I had not installed CUDA. To fix it, I ran sudo apt install cuda-12-6.

For future reference, libnvToolsExt.so.1 is part of the cuda-nvtx-12-6 package and libcusolver.so.11 is part of the libcusolver-12-6 package. Both packages get installed when installing CUDA.

Hi @D3_jshaffer

Please note that the latest release of Isaac ROS is compatible with Jetpack 6.0.
Check the requirement page: Getting Started — isaac_ros_docs documentation

Best,
Raffaello
