Description

Part of #985. Stacked on #1045.

No flat sibling imports — these scripts are independent — but the tree kept its pyproject.toml under python/ and ran as uv run <script>.py, so it needed the same conversion for one install command to work across every example.

uv pip install -e ./examples/oxr
python -m isaacteleop_examples.oxr.test_modular

The GPU CI keeps invoking these by path, not by -m. The test image copies examples/oxr/python/ to /app/tests and runs python <script>, so the entries in CXR_PYTHON_GPU_TESTS just gain the namespace prefix. With no sibling imports the path-based invocation stays correct. Moving that container to -m would mean changing Dockerfile.test, the compose runner and the list together, on a path I cannot reproduce locally — worth doing, but not blind and not here.

The example carried two overlapping READMEs, at the example root and under python/. The python/ one was a subset, so it goes and the root one absorbs its run commands.

Type of change

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation update

Testing

x86_64 / Ubuntu, Python 3.12. Wheel ships 12 modules under isaacteleop_examples/oxr/ with no namespace __init__.py. pre-commit clean.

Not covered: everything here needs a headset and the CloudXR runtime. The CI list change is the risky part — please confirm the GPU job still finds all three scripts.

Checklist

  • I have read and understood the contribution guidelines
  • I have run the linter and formatter with SKIP=check-copyright-year pre-commit run --all-files
  • I have made corresponding changes to the documentation
  • I have added tests that prove my fix/feature works (or explained why not)
  • I have signed off all my commits (git commit -s) per the DCO

No tests: this is a move with no import changes.

Summary by CodeRabbit

  • New Features

    • OpenXR Python examples are now installable as a package with editable installation support.

📝 Walkthrough

Walkthrough

The OpenXR Python examples now use the isaacteleop_examples.oxr package layout. A top-level pyproject.toml defines the package and dependencies. CMake installs the examples at examples/oxr. README instructions use editable installation and module execution. Test plugin paths, CloudXR paths, and documentation references match the new layout. The previous nested Python manifest and README were removed.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 9bdd0

Three OpenXR example scripts cannot run in the CloudXR test-image layout because plugin-path initialization crashes before execution. Resolve the plugin root in a container-compatible way before merging.

run_tests_with_cloudxr.sh now uses isaacteleop_examples/oxr/test_*.py relative to /app/tests, described as a copy of examples/oxr/python/. Nothing in this repo creates /app/tests, so I can't check it here -- worth confirming against whatever builds the test image rather than letting the GPU job find out.

The scripts themselves are fine either way: they only import isaacteleop.*, no intra-example imports, so running them as bare scripts still works.

Use a path resolution that works in the CloudXR image.

CloudXR copies examples/oxr/python/ to /app/tests. In that layout, Path(__file__).resolve().parents[5] raises IndexError before the scripts start.

  • examples/oxr/python/isaacteleop_examples/oxr/test_hand_inactive_on_plugin_stop.py#L25-L25: resolve the plugin root without indexing beyond the /app/tests path.
