Habitat-Lab Tasks, Datasets, and Environments

Use this sub-skill when the user needs to load Habitat task configs, inspect dataset and episode layout, construct habitat.Env or habitat.RLEnv, wrap tasks as Gym environments, use VectorEnv/ThreadedVectorEnv, or diagnose environment/data/config smoke-check failures.

Read First

• API reference: verified constructor signatures, object relationships, lifecycle calls, Gym conversion behavior, and vectorized-env methods.
• Workflows: config-to-env recipes, Gym wrappers, VectorEnv debug mode, navigation/rearrangement/VLN/EQA patterns, validation steps, and skip conditions.
• Data formats: scene/task dataset layouts, Episode fields, task-specific episode extensions, DATASETS-derived paths, and tiny-fixture guidance.
• Troubleshooting: missing assets, Habitat-Sim/graphics failures, VectorEnv hidden errors, action/observation-space mismatches, Gym wrapper issues, and backend failures.

Bundled Script

Use scripts/habitat_config_smoke.py for safe config inspection. It loads a Habitat config, applies Hydra overrides, prints environment/task/simulator/dataset summaries, and only attempts dataset construction when --make-dataset is explicitly provided. It never downloads data and never creates a simulator by default.

Boundary Reminders

• For install, editable package setup, Hydra search path basics, Habitat-Sim installation, CUDA/graphics setup, and dependency repair, route to setup-and-configuration.
• For RL training, evaluator loops, checkpoints, policies, and Habitat-Baselines trainer configuration, route to baselines-training-and-evaluation.
• For real-time HITL apps, interactive keyboard/gamepad/VR control, and app services, route to hitl-apps-and-interaction.
• For registering custom sensors, actions, tasks, measures, datasets, or simulators, route to extension-patterns.
