Can not launch any python file

[utilisateur1191]

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

Isaac Sim installation fail Command failed: /isaac_sim-2021.2.1/omni.isaac.sim.post.install.sh"

and I have an other question, if isaac is correctly installed, so why on omniverse library I don’t have isaac and the launcher button of isaac, I can only launch isaac why command line ? It looks like the installation was not completed because of the error during post install. There maybe be leftover files during the install but the folder will be deleted when you try to install it again. You could also try deleting that folder before a reinstall. There could also be some issues with the VM …

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

(https://docs.omniverse.nvidia.com/app_isaacsim/app_isaacsim/tutorial_required_workflows.html)

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.

3. 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

I also have the same issue, I can not even load the robot from the app itself!
I did change the
“Headless”: True
still encountering the same error in CLI!
why is this example still not loading even in the application?

Hi @ahn.paf - Have you gone through the latest documentation?

Hi, I actually still cannot load the example through the code, I should only import it from examples in the toolbar, in this way, it is not tracking my curser as it should be.
