Public Isaac Sim 6.0 missing isaacsim.kit.xr.teleop.bridge required by IsaacLab 3 / IsaacTeleop XR

Description

Description

When running IsaacLab 3 / IsaacTeleop 1.x live XR teleoperation with public pip Isaac Sim 6.0, the required Kit extension isaacsim.kit.xr.teleop.bridge cannot be resolved from the installed extscache or public extension registries.

The app can initialize and the GR1T2 teleop environment can be created, but the IsaacTeleop XR session fails when trying to acquire OpenXR handles. isaaclab_teleop expects the bridge to polyfill missing omni.kit.xr.system.openxr APIs, including get_instance_proc_addr().

Steps to Reproduce

Environment:

isaacsim==6.0.0.0
isaacsim-extscache-kit==6.0.0.0
isaacsim-extscache-physics==6.0.0.0
IsaacLab commit cfdbe71e96a5bc0e2321b45c69319e38162bf277
isaaclab_teleop==0.3.6
isaacteleop==1.2.107rc1
Python 3.12
Ubuntu 24.04
NVIDIA RTX 4090
Driver 590.48.01
nvidia-smi CUDA version 13.1
PyTorch 2.10.0+cu128

Run:

cd ~/IsaacLab-cfdbe71
source env_isaaclab/bin/activate

./isaaclab.sh -p scripts/environments/teleoperation/teleop_se3_agent.py \
    --task Isaac-PickPlace-GR1T2-WaistEnabled-Abs-v0 \
    --visualizer kit \
    --device cuda:0 \
    --xr

Expected

The public Isaac Sim 6.0 package, extscache, or public extension registry should provide isaacsim.kit.xr.teleop.bridge, or the documentation should state which public Isaac Sim build/container/registry is required for IsaacLab 3 + IsaacTeleop 1.x live XR teleoperation.

Actual

The bridge extension cannot be resolved:

Failed to resolve extension dependencies. Failure hints:
  * No versions of isaacsim.kit.xr.teleop.bridge that satisfies: [enable list] depends on isaacsim.kit.xr.teleop.bridge version *
    - Available packages for isaacsim.kit.xr.teleop.bridge version *:
      (none found)

Then IsaacTeleop crashes:

AttributeError: module 'omni.kit.xr.system.openxr' has no attribute 'get_instance_proc_addr'

The relevant IsaacLab 3 kit file enables the bridge:

xr.openxr.components."isaacsim.kit.xr.teleop.bridge".enabled = true

isaaclab_teleop also enables it directly:

ext_manager.set_extension_enabled_immediate("isaacsim.kit.xr.teleop.bridge", True)

And session_lifecycle.py documents that importing the bridge performs the required OpenXR polyfill:

# Importing bridge also performs polyfill of missing omni.kit.xr.system.openxr functions.
import isaacsim.kit.xr.teleop.bridge as bridge

Question

Is isaacsim.kit.xr.teleop.bridge planned for a public Isaac Sim 6.0.x release? If yes, when should users expect a public pip package, NGC container, or extension registry update that includes it? If it is not planned for public Isaac Sim 6.0.x, what is the supported public Isaac Sim distribution path and expected timeline for IsaacLab 3 + IsaacTeleop 1.x live XR teleoperation?

Hi @lylechan42, thank you for the detailed report and for cross-referencing the related issues.

This is a confirmed packaging gap: isaacsim.kit.xr.teleop.bridge is not included in the public isaacsim==6.0.0.0 pip distribution, its extscache packages, or any publicly documented extension registry, which means live XR teleoperation via IsaacLab 3 / IsaacTeleop 1.x cannot currently be completed using the public pip install path. The same absence has been independently confirmed in the nvcr.io/nvidia/isaac-sim:6.0.0-dev2 container (IsaacLab #5221, #5368, IsaacTeleop #160).

We are routing this to the relevant engineering and product teams to determine whether isaacsim.kit.xr.teleop.bridge will be made available in a public Isaac Sim 6.0.x release, a specific container image, or a private/partner registry, and to ensure the IsaacLab 3 + IsaacTeleop XR documentation is updated to reflect the correct supported distribution channel.

At this time there is no known public workaround that restores the missing OpenXR polyfill (get_instance_proc_addr) without the bridge extension. We will update this issue once we have clarity on availability and any interim guidance. Apologies for the inconvenience.
