Hello!
I'm using Jetson Nano(JP4.6) With ROS 2 Eloquent. I built Nav2 from the source code, made a test description of URDF, but could not run display.launch.py .
Here is the output I see when trying to run:
robot@robothost:~$ ros2 launch vector_description display.launch.py
[INFO] [launch]: All log files can be found below /home/robot/.ros/log/2022-02-18-14-13-30-610366-robothost-18354
[INFO] [launch]: Default logging verbosity is set to INFO
[ERROR] [launch]: Caught exception in launch (see debug for traceback): Caught exception when trying to load file of format [py]: cannot import name 'Command'
This is what the beginning looks like display.launch.py which I copied from the tutorial

Has anyone encountered this? How can I solve this problem?
