Maybe Dashing is not supported. I think it's too old...
Hello @fmrico , Thank you for your reply. I am now testing with ros-eloquent and latest intelrealsense2 ros-development branch. I have detection with darknet ros but get following error when launched darknet_ros_3d. [ERROR] [darknet3d_node-1]: process has died [pid 4197, exit code -11, cmd '/home/robolab/ros2_ws/install/darknet_ros_3d/lib/darknet_ros_3d/darknet3d_node --ros-args -r __node:=darknet3d_node --params-file /home/robolab/ros2_ws/install/darknet_ros_3d/share/darknet_ros_3d/config/darknet_3d.yaml'].
I have given correct topics in the darknet3D.yaml files.
Hi @miga94
You are obtaining a segmentation fault that does not give you much information.
Build with CMAKE_BUILD_TYPE
to Debug
or RelWithDebInfo
and launch the node with prefix='xterm -e gdb -ex run --args'
Best
Hello @fmrico , If I understood you I ran the following command while running the node: xterm -e gdb -ex run --args ros2 launch darknet_ros_3d darknet_ros_3d.launch.py
Is this formulation correct? Attached is the screenshot what I got from this.
Hi!!
No. These are more detailed instructions to use gdb to debug a segmentation fault:
Clean up the workspace by deleting build install and log.
Open another terminal and compile with: colcon build --symlink-install --cmake-args -DCMAKE_BUILD_TYPE=Debug
Modify the launcher so that node is launched with gdb in a separate terminal (you must have xterm installed): darknet3d_node = Node( package='darknet_ros_3d', node_executable='darknet3d_node', prefix='xterm -e gdb -ex run --args', node_name='darknet3d_node', output='screen', parameters=[config_file_path] )
Launch it
When it fails, it will tell you the line. Use 'bt' and other gdb commands to see what happened. If you want, send me the output.
Good luck!!
