ORBIT-Surgical not working with Isaac Sim 5.1.0 / Isaac Lab 2.3.0 (ModuleNotFoundError)

Hello NVIDIA Community,

I am trying to run ORBIT-Surgical benchmark surgical tasks using NVIDIA Isaac Sim 5.1.0 and Isaac Lab 2.3.0, but we are facing persistent installation and compatibility issues.

System / Hardware Details

  • OS: Ubuntu (22..04)

  • GPU: NVIDIA GeForce RTX 5070 Ti (16 GB VRAM)

  • NVIDIA Driver: 580.105.08

  • CUDA Version: 13.0

  • GPU Mode: Default (no MIG)

  • Python Environment: Conda-based environment

Current Behavior

  • Isaac Sim 5.1.0 launches successfully:

    ./isaac-sim.sh

  • ORBIT-Surgical tasks fail when launched via Isaac Lab:

    ./isaaclab.sh -p source/standalone/environments/state_machine/lift_needle_sm.py --teleop keyboard

    Error:

    ModuleNotFoundError: No module named 'omni.isaac.lab'

What I Have Tried

  • ./isaaclab.sh --install → partial extension installation failures

  • pip install -e . → flat-layout / multiple package issues

  • Conda environment (orbitsurgical) → pydantic_core errors

  • source setup_python_env.sh → SRE / module version mismatch

Despite multiple clean installs and troubleshooting attempts, the issue persists.

Clarification Needed

  1. Does ORBIT-Surgical currently support Isaac Sim 5.1.0 and Isaac Lab 2.3.0?

  2. What is the recommended, known-working software stack for ORBIT-Surgical?

    • Isaac Sim version

    • Isaac Lab version

    • CUDA & NVIDIA driver versions

    • Python version and required libraries

My goal is to run benchmark surgical tasks only (no RL or IL training).

Any working setup details, guidance, or references from the community would be greatly appreciated.

Thank you in advance for your help.
