Use when packaging, running, validating, or troubleshooting Isaac Lab-Arena policy evaluation in NPA, including the public runtime-fetch image, zero/replay/RSL-RL modes, B200 state-only routing, RTX video routing, artifacts, and upstream alpha limitations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Isaac Lab-Arena Operate the pinned upstream `isaac-sim/IsaacLab-Arena` 0.3.0 release at `ed0fd12be862078be316c73eb7cf423ba9b1c5cd`. This release calls itself alpha, warns that APIs are unstable and incomplete, and says not to use it in production. Treat the NPA integration as a hardened, reproducible wrapper for its supported evaluation entrypoint; never describe upstream Arena itself as production-ready. ## Capability and terms The only supported execution path is upstream `isaaclab_arena/evaluation/policy_runner.py`. It must complete scored episodes and retain the upstream JSONL plus HTML report. Imports, `--help`, a simulator launch, or an incomplete fixed-step rollout do not establish evaluation. The capability payload's `upstream_workflows` also lists agentic environment generation, experiment orchestration, sensitivity analysis, teleoperation, Mimic data generation, imitation learning, and reinforcement learning. These are `unsupported`, `input_required`, and `upstream_alpha` in the NPA Arena integration. Their pinned upstream entrypoints or documentation and required inputs are listed for discovery. Do not route them to the evaluation runner or …

How to install
mdr add nebius/nebius-physical-ai/isaac-arena@sha256:539c3c34c0bd2d13The line at the top of this page pins the label git:20260923.8206cee, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
