examples(noitom): package under isaacteleop_examples

[jiwenc-nv]

Description

Part of #985. Stacked on #1040.

The three modules imported each other as top-level modules, and the README documented the consequence rather than fixing it — every Isaac Lab command carried PYTHONPATH=~/IsaacTeleop/examples/noitom:$PYTHONPATH. This moves the tree to the layout in examples/README.md and deletes the prefix.

The example gains its first pyproject.toml. isaaclab and gymnasium are deliberately not dependencies: noitom_tasks.py runs inside an Isaac Lab environment that already provides them, and neither installs from PyPI. The README now says to install into that interpreter, which is what replaces the PYTHONPATH prefix:

./isaaclab.sh -p -m pip install -e ~/IsaacTeleop/examples/noitom

and the callback becomes --external_callback isaacteleop_examples.noitom.noitom_tasks.register_tasks.

One import lived inside a function body, indented, so it needed catching separately from the module-level ones — worth knowing if you review the other trees.

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 the four modules under isaacteleop_examples/noitom/ with no namespace __init__.py. An AST sweep of the tree confirms no sibling resolves as a top-level import any more.

Not covered, and I cannot cover it: nothing here has a Noitom mocap suit or an Isaac Lab install. The dependency list is inferred from imports, and this example never had one before — a missing runtime dep would only show on the machine with the suit attached. Please run both README paths (the MCAP recording and the Isaac Lab teleop task) before merging.

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, and no CI has the hardware.}

Summary by CodeRabbit

• New Features

  • Added installable packaging for the Noitom examples, supporting Python 3.11–3.13.
  • Updated Noitom setup and recording instructions to install and launch the example as a package.

• Bug Fixes

  • Improved Noitom module resolution across repository and installed environments.
  • Updated default recording output behavior to use the current working directory.
  • Simplified Isaac Lab teleoperation setup by removing manual path configuration.

📝 Walkthrough

Walkthrough

The Noitom example now has Hatch packaging metadata and package-relative imports. Plugin discovery resolves from the repository or install-prefix root. Default recordings resolve relative to the current working directory. Recording and teleoperation instructions install the example into the active interpreter and invoke fully qualified module paths without PYTHONPATH.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Loading

Merge Risk: 🟠 High · up to c376e

Teleoperation can fail while loading the task, and regular installation can fail to auto-launch the Noitom plugin. Both workflows should be fixed before merge.

Read the diff line by line: the only changes are four bare intra-example imports becoming relative, plus the new pyproject.toml and namespace __init__.py. No logic change.

Not installed by install_python_example(), so there is no install tree to check, and I have no Noitom hardware here — but the diff carries nothing runnable that the move could break.

Use the packaged module in env_cfg_entry_point. Isaac Lab resolves this module:Class value as an import path when loading the environment configuration. The documented callback imports isaacteleop_examples.noitom.noitom_tasks, but the package installs no top-level noitom_tasks module. The documented teleoperation command can therefore fail with ModuleNotFoundError: No module named 'noitom_tasks'.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Make regular Noitom installs locate the plugin. The examples contract states that uv pip install ./examples/<name> works for every example, and examples/noitom/pyproject.toml builds a wheel. In a regular install, parents[5] points to the environment prefix, not the repository, so both helpers miss the repository's install/plugins directory.

With auto-launch enabled, noitom_tasks._noitom_plugin_configs() raises Noitom plugin directory not found, while record_noitom_full_body.main() exits with no installed plugin directory found. Accept an explicit plugin search path, such as ISAAC_TELEOP_PLUGIN_PATH, in both helpers and retain the current ancestor candidates for source and editable installs.
