I'm going to do ros2 with ydlidar x2. I was going to install slam_toolbox to map it, but I couldn't, so I was advised to install rf2o_laser_odometry. I followed your advice,

ros2 launch ydlidar_ros2_driver ydlidar_launch.py
ros2 run tf2_ros static_transform_publisher 0 0 0 0 0 0 base_link laser_frame
ros2 launch rf2o_laser_odometry rf2o_laser_odometry.launch.py laser_scan_topic:=scan
ros2 launch slam_toolbox online_async_launch.py `base_frame:=base_link`

but there was an error. [ERROR] [rf2o_laser_odometry_node-1]: exception occurred while executing process: Traceback (most recent call last): File "/opt/ros/humble/lib/python3.10/site-packages/launch/actions/execute_local.py", line 546, in __execute_process transport, self._subprocess_protocol = await async_execute_process( File "/opt/ros/humble/lib/python3.10/site-packages/osrf_pycommon/process_utils/async_execute_process_asyncio/impl.py", line 139, in async_execute_process transport, protocol = await _async_execute_process_nopty( File "/opt/ros/humble/lib/python3.10/site-packages/osrf_pycommon/process_utils/async_execute_process_asyncio/impl.py", line 45, in _async_execute_process_nopty transport, protocol = await loop.subprocess_exec( File "/usr/lib/python3.10/asyncio/base_events.py", line 1667, in subprocess_exec transport = await self._make_subprocess_transport( File "/usr/lib/python3.10/asyncio/unix_events.py", line 207, in _make_subprocess_transport transp = _UnixSubprocessTransport(self, protocol, args, shell, File "/usr/lib/python3.10/asyncio/base_subprocess.py", line 36, in init self._start(args=args, shell=shell, stdin=stdin, stdout=stdout, File "/usr/lib/python3.10/asyncio/unix_events.py", line 799, in _start self._proc = subprocess.Popen( File "/usr/lib/python3.10/subprocess.py", line 969, in init self._execute_child(args, executable, preexec_fn, close_fds, File "/usr/lib/python3.10/subprocess.py", line 1733, in _execute_child self._posix_spawn(args, executable, env, restore_signals, File "/usr/lib/python3.10/subprocess.py", line 1678, in _posix_spawn self.pid = os.posix_spawn(executable, args, env, **kwargs) OSError: [Errno 8] Exec format error: '/home/car/ros2_ws/install/rf2o_laser_odometry/lib/rf2o_laser_odometry/rf2o_laser_odometry_node'

Help me plz...

Found the solution! For me it was adding: #!/usr/bin/env python3 at the top of the executable file
