Isaac SIM in omniverse not launching

No it doesn’t hang or crash, when I click on launch it just says launching for a while and then stops.

and I don’t see any Extra Args text box in omniverse.
What command to run isaac sim from terminal?

When you click Launch, the Isaac Sim App Launcher window should appear, then click Launch again.
You can run Isaac Sim directly with /home/krishna/.local/share/ov/pkg/isaac_sim-2021.1.1/isaac-sim.sh -v from terminal.

When I click on launch in the image I attached nothing happens.
But I tried the terminal command you sent, that works.
I haven’t setup nucleus yet, so will set it up and see if everything is working.

@Sheikh_Dawood
I created an account in Nucleus,
I am following this documentation.
https://docs.omniverse.nvidia.com/app_isaacsim/app_isaacsim/setup.html#isaac-sim-setup-nucleus-add-assets

But there is no option to create a folder

See step #4. Currently, we can only create the folder in Isaac Sim.
~/.nvidia-omniverse/logs/Kit/Isaac-Sim/2021.1

Can I take a look at the other logs below? There could be an error in the Isaac Sim App Launcher or the Omniverse Launcher itself.
~/.nvidia-omniverse/logs/Kit/Isaac-Sim_App_Launcher/2021.1
~/.nvidia-omniverse/logs/launcher.log

Ya in the steps mentioned the create a folder in a UI right, Where can I find it and where should download the asset file to.
Becuse right now I have “nucleus service not configured warning now”

Log files:
kit_20210722_105105.log (37.6 KB)
launcher.log (51.7 KB)

Looks like the Isaac Sim App Launcher exited with this error:

2021-07-22 05:21:05 [93ms] [Error] [carb.scripting-python.plugin] TypeError: launch_app() missing 1 required positional argument: ‘app_version’

Can you try check the top right bell icon on the Omniverse Launcher if you have an update. Then try reinstall Isaac Sim.

There are not updates and I have already uninstalled it and installed it. Still the same issue persists

/home/krishna/.local/share/ov/pkg/isaac_sim-2021.1.1/isaac-sim.sh -v

This command works and opes isaac sim.
But I was trying to run Jetbot basic example and Isaac sim crashed.

Please share the log file at ~/.nvidia-omniverse/logs/Kit/Isaac-Sim/2021.1.

Have you installed Nucleus and uploaded the Isaac folder before running the Jetbot sample?

Yes
Isaac sim crashed because it filled the entire 16gb ram.

@Sheikh_Dawood

I upgraded my ram to 32 gb ram.
Now the environments are getting loaded.
But now when I try to move the bot in Jetbot sample I get this error:

Bot doesn’t move as well

I tried reinstalling isaac sim, but the launching issues is still there

I can only launch it from terminal using
/home/krishna/.local/share/ov/pkg/isaac_sim-2021.1.1/isaac-sim.sh -v

Which version of the Launcher are you one. There should be a new version 1.2.10 with some fixes.

Please also post the full log with the error. There may be other clues in the log file.
Are you able to run the other samples like Franka Block Stacking and UR10 Palletizing from the Isaac Examples menu?

from where can I download the 1.2.10 version?

No after upgrading my ram 32gb I am able to run stuff on isaac sim.
But one issue I encountered while trying kaya joystick, when I used the joystick the camera in isaac sim started rotating and never stopped.

To see the current version, click the “User” icon on the top right of Omniverse Launcher then slect “About”.
If there is a notification in the “Bell” icon, you may see that there is an update. To update, restart the Omniverse Launcher.

It is in 1.2.8 and there are no updates.

Sorry about that. 1.2.10 have not been released to production yet.

@krishnavadithya Do you still have the launcher issue? Can you run Isaac Sim from launcher?
