Greptile Summary

This PR improves the benchmark version-recording infrastructure by replacing fragile attribute-chain strings (e.g. "app.get_app().get_build_version") with dedicated _get_isaac_sim_version and _get_kit_version methods, fixing the underlying __import__ → importlib.import_module bug along the way, and surfacing isaacsim_version, kit_version, and isaaclab_ov_version in the printed summary report.

• record_version_info.py adds two new resolution strategies — reading from the running omni.kit.app instance (trying three method names in order) and falling back to Carb settings keys — plus a callable-attribute check in the generic _get_version helper.
• backends.py reads the three new metadata keys from the version phase and prints them in the summary box.
• Four new unit tests cover the Isaac Sim utility path, the live Kit app path, the Carb settings fallback, and the guarantee that no Kit import is triggered in kitless environments.

Confidence Score: 4/5

Safe to merge — all changes are additive, read-only version introspection with no effect on simulation logic or data pipelines.

The refactored Kit/Isaac Sim version detection is well-structured and the fallback chain is correct. The one minor gap is that str(get_isaac_sim_version()) doesn't guard against a hypothetical None return, and the getattr(carb, "settings", None) fallback in _get_kit_settings_version has no corresponding test. Neither affects production correctness today, but both are worth tidying up.

record_version_info.py — specifically the _get_isaac_sim_version wrapper and the untested carb attribute-fallback branch in _get_kit_settings_version.

Important Files Changed

Filename	Overview
source/isaaclab/isaaclab/test/benchmark/recorders/record_version_info.py	Core change: replaces brittle attribute-chain strings with dedicated _get_isaac_sim_version/_get_kit_version methods; fixes import → importlib.import_module and adds callable() check; logic is sound but has one minor issue where str(get_isaac_sim_version()) could surface "None" if the wrapped function ever returns None
source/isaaclab/isaaclab/test/benchmark/backends.py	Adds three new version fields (isaacsim_version, kit_version, isaaclab_ov_version) to the summary print block; keys correctly match the StringMetadata names produced by get_data() via the f"{package}_version" convention
source/isaaclab/test/benchmark/test_recorders.py	Adds four new tests covering the Isaac Sim utility path, Kit app path, Carb settings fallback, and the kitless no-import guarantee; the carb attribute-fallback path (getattr(carb, "settings", None)) is not exercised by any test

_{Reviews (1): Last reviewed commit: "Adds version output for Kit and isaac Si..." | Re-trigger Greptile}

[greptile-apps]

get_isaac_sim_version() returns a packaging.version.Version object (never None), so str(...) is safe today. However, if the function signature ever relaxes to allow None (e.g. in offline/kitless environments), str(None) evaluates to the literal string "None", which passes the if version: guard in _record and would appear verbatim in benchmark output. A simple None check here makes the intent explicit and guards against future regressions.

Suggested change

	try:
	from isaaclab.utils.version import get_isaac_sim_version
	return str(get_isaac_sim_version())
	except Exception:
	try:
	from isaaclab.utils.version import get_isaac_sim_version
	version = get_isaac_sim_version()
	return str(version) if version is not None else None
	except Exception:

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Carb attribute-fallback path not exercised

_get_kit_settings_version has a secondary path — carb_settings = getattr(carb, "settings", None) — that is reached when carb is in sys.modules but carb.settings is not a separate module entry. The current test only covers the direct sys.modules["carb.settings"] lookup. A test that adds carb (with a .settings attribute) to sys.modules but leaves carb.settings absent would complete coverage of that branch.
