SSD File Naming Issue

See original GitHub issue

Hi, I faced with a problem with semantic while executing config for the challenge. Here is the code:

_config = config_env.TASK_CONFIG
_dataset = make_dataset(
                id_dataset=_config.DATASET.TYPE, config=_config.DATASET)
_episodes = (_dataset.episodes
            if _dataset
            else cast(List[Episode], []))
iter_option_dict = {
            k.lower(): v
            for k, v in _config.ENVIRONMENT.ITERATOR_OPTIONS.items()
        }
_episode_iterator = _dataset.get_episode_iterator(
            **iter_option_dict)
_config.defrost()
_config.SIMULATOR.SCENE = _dataset.episodes[0].scene_id
_config.freeze()
number_of_episodes = len(_dataset.episodes)
_sim = make_sim(id_sim=_config.SIMULATOR.TYPE, config=_config.SIMULATOR)
_task = make_task(
            _config.TASK.TYPE,
            config=_config.TASK,
            sim=_sim,
            dataset=_dataset)

And here is the error:

According to this message, a *basis.scn or *info_semantic.json file is needed. How can I get these files?

I realized that file hm3d_annotated_basis.scene_dataset_config.json was not in /home/kirill/habitat-lab/data/scene_datasets/hm3d directory. After copying it into the directory, semantic worked. @jturner65 @srama2512 Thank you for your help!

Yes, hm3d_annotated_basis.scene_dataset_config.json file is located in /home/kirill/habitat-lab/data/scene_datasets/hm3d directory. Here is the file (zipped): hm3d_annotated_val_basis.scene_dataset_config.json.gz

I executed the following code:

import habitat_sim

path_to_hm3d = "/home/kirill/habitat-lab/data/scene_datasets/hm3d"
backend_cfg = habitat_sim.SimulatorConfiguration()
backend_cfg.scene_id = f"{path_to_hm3d}/val/00876-mv2HUxq3B53/mv2HUxq3B53.basis.glb"
#backend_cfg.scene_id = "mv2HUxq3B53"
backend_cfg.scene_dataset_config_file = f"{path_to_hm3d}/hm3d_annotated_basis.scene_dataset_config.json"

sem_cfg = habitat_sim.CameraSensorSpec()
sem_cfg.uuid = "semantic"
sem_cfg.sensor_type = habitat_sim.SensorType.SEMANTIC

agent_cfg = habitat_sim.agent.AgentConfiguration()
agent_cfg.sensor_specifications = [sem_cfg]

sim_cfg = habitat_sim.Configuration(backend_cfg, [agent_cfg])
sim = habitat_sim.Simulator(sim_cfg)

print("# objects: {}".format(len(sim.semantic_scene.objects)))
