:computer: Using

1. Server-Client

   • Setup server.yaml and tune hloc.yaml us needed.

   • Put the data into IO_root you defined as following structure

     UNav-IO/
     ├── data
     │   ├── destination.json
     │   ├── PLACE
     │   │   └── BUILDING
     │   │       └── FLOOR
     │   │           ├── access_graph.npy
     │   │           ├── boundaries.json
     │   │           ├── feats-superpoint.h5
     │   │           ├── global_features.h5
     │   │           ├── topo-map.json
     │   │           └── floorplan.png
     

     Note that you need to rerun Path_finder_waypoints.py using step2_automatically.sh if you do not have access_graph.npy
