Inspect the requirements, then remove --plan to prepare a project. Preparation verifies the archive SHA256 and preserves exact source pins. --install-deps explicitly installs dependencies. Run the returned simulation command separately.

Environment

Runtime: metaworld 3.1.1
Robot: sawyer
Controller: scripted-policy
Observation: privileged_simulator_state
OS / architecture: linux / x86_64
Python: >=3.11,<3.12

Compatibility status: hub_verified

Privileged simulator observations and goal/state feedback. No physical sensor validation.

Requirements

Linux x86_64; CPU simulation; see retained receipt for the exact host environment

Headless. EGL libraries are required for MuJoCo imports; PushT uses SDL dummy video. No interactive display.

Packages: metaworld==3.1.1, mujoco==3.3.0, numpy==1.26.4, gymnasium==1.2.0, packaging==25.0

Direct runtime versions are pinned and measured. The receipt retains the complete environment freeze; prepare records the installed environment. System drivers are separate host requirements.

External API keys: none.

Success: All declared goal and finite-state checks pass; exit 0 with task_complete. Five consecutive native task-success predicates within 500 dynamic simulation steps. Task-specific success definitions come from the pinned upstream environment; this is not a general manipulation score.

Timeout: 180 seconds. Terminate the adapter at the recorded timeout. No physical hardware is opened.

Failure modes

Invalid input or source checksum
Different pinned package version
Unavailable runtime/driver
Goal not reached within bounded steps
