[Question] When running the script you specified, an error occurred. How can I solve it?

The error message is as above. I've reinstalled it but it still doesn't work. This happened after I accidentally opened two scripts and interrupted one of them.

[ssakkout]

Running multiple scripts or interrupting one can cause state corruption, since you already reinstalled it, try Recreating the Conda Environment:
Delete the existing Conda environment (isaaclab) and recreate it using the setup instructions provided in the Isaac Sim documentation.

and try:

• Restarting Isaac Sim.
• Reload the scene or USD file to ensure a clean state.

[ssakkout]

try checking those paths for the cache:
~/.cache/ov/
~/.cache/nvidia-omniverse/
~/localdisk/ov/cache/

To update Isaac Sim:

• Open Isaac Sim
• Go to Window → Extension Manager
• Click on the Settings gear icon
• Click "Check for Updates"
• If updates are available, they will be shown and you can install them

To check required extensions:

• Open Isaac Sim
• Go to Window → Extension Manager
• Look for these essential extensions and ensure they're enabled:
• omni.isaac.core
• omni.isaac.sim
• omni.isaac.kit
• omni.replicator.core (if you're using Replicator)
• omni.physx
• omni.kit.uiapp

You can also check installed extensions via command line: ./<isaac_sim_directory>/python.sh -m pip list | grep omni

[VinHo-C]

I feel that my isaacsim is different from what you said, I can't find the update button in extension, and I can't find the file using the command line。

(lab) chenwenhao:~$ ./<isaac_sim_directory>/python.sh -m pip list | grep omni

bash: isaac_sim_directory: No such file or directory

(lab) chenwenhao:~$ isaacsim

And, I can't run the spawn_prims.py

[ssakkout]

The main error appears to be that Isaac Sim cannot access the default ground plane asset, Could not open asset @http://omniverse-content-production.s3-us-west-2.amazonaws.com/Assets/Isaac/4.2/Isaac/Environments/Grid/default_environment.usd@

The cache server is not configured: Unable to detect Omniverse Cache Server. File /home/chenwenhao/.nvidia-omniverse/config/omniverse.toml is not found

maybe you need to create a local ground plane instead of using the default one or use a local USD file for the ground plane

and create the omniverse configuration mkdir -p ~/.nvidia-omniverse/config touch ~/.nvidia-omniverse/config/omniverse.toml

[VinHo-C]

Thanks for your answer. I have solved this problem because I did not access the assets inside.
