Hello, I am new to using Isaac Sim and ROS2. I am trying to implement SLAM for a research project I’m working on. I want to get a SLAM system running using the example scene before porting it to my own project. I have been following this tutorial, and I believe I installed everything properly but I…

Hey @kylerwitvoet ! Could you please check which branch are you on for isaac_ros_common package? You need to make sure that you are on release-3.2 branch. For isaac_ros_visual_slam, did you install debian package or did you build from source? If you built from source, please also make sure that you …

Hi @zhengwang @kylerwitvoet ! I confirm I have the same issue Failed to initialize CUVSLAM tracker: 4 - x86_64 - ZED Camera , with both ROSBag and ZED Camera tutorials

tried both from source and debian package

@alberto.remus What is your output of nvcc --version?

The issue persists. Can we have someone to help out. I tried on two different machines with CUDA 12.6 and continue to have see “Failed to initialize CUVSLAM tracker: 4” . In fact i see the same error when i try running with your rosbag

Hi @formegham could you please try changing the verbosity level of isaac_ros_visual_slam ( link to ROS params ) to 1 and see what is the error in the log file?

We will have a minor release for Isaac ROS 3.2.6 which will make the verbosity level of isaac_ros_visual_slam to 1 by default.

I was able to resolve the error by upgrading by Nvidia drivers to 570 which now has CUDA 12.8. after that I was getting warnings of jitter threshold being high which I resolved by setting the image_jitter_threshold based on my camera fps 30 fps → threshold of 35 ms 10 fps → threshold of ~100 or 1…

I will go ahead and close this topic as no future questions are posted here. But please feel free to open a new one if the problem is not solved.
