Overview

Concrete function for composing hierarchical RL experiment configurations with skill definitions and high-level policy selection, provided by habitat-baselines.

Description

The same get_config function from habitat-baselines is used but with HRL-specific YAML configs (rl_hierarchical.yaml, rl_skill.yaml). These configs define the hierarchical_policy section including defined_skills mapping, high_level_policy settings, and skill checkpoint paths.

Usage

Called with HRL-specific config paths (e.g., rearrange/rl_hierarchical.yaml) and overrides for skill checkpoint paths and high-level policy selection.
