Implementation:Facebookresearch Habitat lab Task dataset YAML config

Overview

Concrete YAML configuration files for defining Habitat tasks and datasets, composed via Hydra defaults lists.

Description

Habitat provides pre-defined YAML configs for standard tasks and datasets:

• Task YAMLs: `habitat-lab/habitat/config/habitat/task/pointnav.yaml`, `objectnav.yaml`, etc.
• Dataset YAMLs: `habitat-lab/habitat/config/habitat/dataset/pointnav/gibson.yaml`, etc.

These are composed via Hydra defaults and define the full evaluation specification.

Usage

Reference task and dataset configs in your benchmark or training config. Use Hydra overrides to switch between tasks and datasets.
