[Question] Unitree Go1 problem with Isaac Lab script

[Marsak24]

Hello everyone, I was trying to run the couple of examples provided by Isaac Lab, they worked fine except for the Unitree Go1. It is not being imported to the environment.

The command I ran is : python 'train'.py --task=Isaac-Velocity-Flat-Unitree-Go1-v0 --num_envs=128

I got a couple of warnings, similar to this one: _2025-04-11 13:54:00 [119,907ms] [Warning] [omni.usd] Warning: in ReportErrors at line 2890 of /builds/omniverse/usd-ci/USD/pxr/usd/usd/stage.cpp -- In </World/envs/env_63/Robot/RR_hip/visuals>: Could not open asset @http://omniverse-content-production.s3-us-west-2.amazonaws.com/Assets/Isaac/4.5/Isaac/IsaacLab/Robots/Unitree/Go1/Props/instanceable_meshes.usd@ for reference introduced by @http://omniverse-content-production.s3-us-west-2.amazonaws.com/Assets/Isaac/4.5/Isaac/IsaacLab/Robots/Unitree/Go1/go1.usd@</go1/RR_hip/visuals>. (recomposing stage on stage @anon:0x58bdf9408fc0:World0.usd@ <0x58bdfed65500>)

I am using the files without changing anything on them, so I am confused why it is not able to import the robot?. [The USD file opens normally when I import it manually]

Thank you

Thank you for posting this. This is typically related to the Nucleus setup. Which version of Isaac Lab and Isaac Sim are you using? Which steps did you follow to install? Thanks.

@RandomOakForest Apologies, I haven't got a notification of this reply. I am using Isaac sim 4.5 and Isaac lab 2.0 for Isaac sim I followed the 'Workstation Installation' in the documentation and for Isaac lab I followed the pip installation guidelines in the documentation. (the rest of the examples run fine except for Go1)
