habitat-pixeledl's Issues

python examples/example.py doesn't work.pointnav.yaml file gives error of sensor_name or sensor_type

hello..I have followed installation procedure from point 1 to 5 as mentioned in Installation Instructions but when i run python examples/example.py mentioned in point 6 to start(test) habitat simulator,Errors related to pointnav.yaml file occurs.I have changed this file as given below:
ENVIRONMENT:
MAX_EPISODE_STEPS: 500
SIMULATOR:
AGENT_0:
SENSORS:
- TYPE: 'RGB'
WIDTH: 256
HEIGHT: 256
HABITAT_SIM_V0:
GPU_DEVICE_ID: 0
DEPTH_SENSOR:
WIDTH: 256
HEIGHT: 256
TASK:
TYPE: Nav-v0
SUCCESS_DISTANCE: 0.2

SENSORS: ['POINTGOAL_WITH_GPS_COMPASS_SENSOR']
POINTGOAL_WITH_GPS_COMPASS_SENSOR:
GOAL_FORMAT: "POLAR"
DIMENSIONALITY: 2
GOAL_SENSOR_UUID: pointgoal_with_gps_compass

MEASUREMENTS: ['DISTANCE_TO_GOAL', 'SUCCESS', 'SPL']
SUCCESS:
SUCCESS_DISTANCE: 0.2

but errors related to sensor_name is coming.Following are the errors:
2024-05-09 23:20:05,289 Initializing dataset PointNav-v1

Kindly guide me what changes need to be made to run habitat simulator successfully.Thanks.
