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: maniskill 3.0.0b22
Robot: panda
Controller: pd_joint_pos
Observation: state
OS / architecture: linux / x86_64
Python: >=3.10,<3.11

Compatibility status: contributor_reported

Reads ground-truth object poses, collision geometry and robot state directly from the simulator. Not an RGB-only policy.

Requirements

Linux x86_64 CPU; SAPIEN wheel needs glibc >=2.28

disabled explicitly: render_backend=none, render_mode=None, state observations and CPU simulation; graphics paths require separate Vulkan setup

Packages: torch==2.5.1, numpy==1.26.4, sapien==3.0.0, mplib==0.1.1, fast_kinematics==0.2.2

Direct dependencies pinned; transitive dependencies resolved by pip and captured in the prepared project. No bit-for-bit environment guarantee.

External API keys: none.

Invocation

Entrypoint: mani_skill.examples.motionplanning.panda.solutions.pick_cube:solve

{
  "argv": [
    "{python}",
    "{recipe_dir}/run.py",
    "--seed",
    "0"
  ],
  "inputs": {
    "task": "PickCube-v1",
    "seed": 0,
    "robot": "panda",
    "controller": "pd_joint_pos",
    "obs_mode": "state",
    "sim_backend": "cpu",
    "render_backend": "none"
  },
  "outputs": {
    "format": "last stdout line JSON",
    "fields": [
      "status",
      "success",
      "elapsed_steps",
      "task",
      "seed",
      "runtime",
      "robot",
      "controller",
      "observation",
      "sim_backend",
      "render_backend"
    ],
    "error_fields": [
      "status",
      "reason_code",
      "error_type",
      "message"
    ]
  }
}

Success: PickCube-v1 env info.success is true after upstream solver finishes; adapter exit 0 only when success is true.

Timeout: 180 seconds. Stop after one seed; no retries to conceal failures. Use an external 180-second process timeout.

Failure modes

Dependency installation unavailable or incompatible
Required Linux mplib wheels unavailable on host OS
Motion planning reports failure or env info.success is false
Runtime exception or asset download failure

Evidence

Runtime: not_run / not_run

Intake structure checks only. Changed recipe runtime, dependency installation, imports and robot tasks were not run by the hub.

Submitter reports and hub verification remain separate. Source review does not establish task success.
