Can not launch any python file

Hello, so I have few problem with isaac sim installation related here

But i thing it’s ok, I can launch Isaac sim websocket. but now, I am pursuing with the tutorial of isaac sim.

(2. Isaac Sim Workflows — Omniverse Robotics documentation)

So, I can manually launch the simulation of follow target robot, by selecting it, in the menu at upper left of the screen in the Isaac examples menu.

But when I tape this command in the isaac folder: ./python.sh standalone_examples/api/omni.isaac.franka/follow_target.py
I have this error :

CLI follow_target (11.2 KB)

I don’t understand why. i can launch manually the simulation but not with command line and python file.

Virtual machine Ubuntu 18.04 os
Quadro RTX 6000
driver : nvidia 470.94
cuda : 11.4

Thank you for your help.

I found this but i don’t know what to do with this information.

  1. When running samples from the standalone_examples via ./python.sh they might not exit/shutdown cleanly:

    [Warning] [carb.tasking.plugin] Leaking 1 carb::tasking::Counter instances!
    Shutting Down Complete
    ./python.sh: line 27: 8164 Segmentation fault (core dumped) $python_exe $@
    There was an error running python

The standalone python samples cannot run headless by default.
You will need to modify the example to set
"headless": False
to True
and then see Python Environment — Omniverse Robotics documentation
standalone_examples/api/omni.isaac.kit/livestream.py
on how to enable the livestream client for a standalone python sample
