Failed to initialize CUVSLAM tracker: 4 - x86_64 - ZED Camera

Hi,

I followed the tutorial in for ZED2i camera in isaac_ros_visual_slam — isaac_ros_docs documentation

For ZED2i I successfully managed to complete the setup: Isaac ROS ZED Setup — isaac_ros_docs documentation

All installations with Docker for x86_64 seemed to be successful.

The problem arises when executing:

ros2 launch isaac_ros_examples isaac_ros_examples.launch.py launch_fragments:=zed_stereo_rect,visual_slam pub_frame_rate:=30.0 base_frame:=zed2_camera_center camera_optical_frames:="['zed2_left_camera_optical_frame', 'zed2_right_camera_optical_frame']" interface_specs_file:=${ISAAC_ROS_WS}/isaac_ros_assets/isaac_ros_visual_slam/zed2_quickstart_interface_specs.json

I tried to follow similar issues, but they seemed to be more related to Jetson: Failed to initialize CUVSLAM tracker: 4

Do you have any suggestion to debug this problem?

As an additional notice, the problem seemed to arise also for ROSBag

Hi @alberto.remus

If this issue is related also to the ROSbag, please ensure that everything is well installed and works; maybe the issue is not related to the camera.

Hi @Raffaello,

I confirm that the problem is related to the ROSbag so I agree it is better to focus on that (I’m going to edit the title).

I tried a fresh installation and still getting this issue on my RTX 3080 Laptop GPU, do you have any hint to narrow down the problem?

Thanks!

As additional information, my local machine has:
NVIDIA-SMI 550.120 Driver Version: 550.120 CUDA Version: 12.4

Hi @alberto.remus

I think your issue is also related to other topics:

I add in this discussion @Ahung to keep you updated

Hi @alberto.remus,

If you are using Isaac ROS 3.2, please upgrade CUDA 12.6+ according to the system requirements.
