Rendering with ScanNet

[xz6014]

Hi there,

Hope that you could help.

I was trying to render a scannet scene with the COLOR SensorType, and I was getting the following error and warnings:

[16:14:25:206625]:[Warning]:[Metadata] SceneDatasetAttributes.cpp(107)::addNewSceneInstanceToDataset : Dataset : 'default' : Lighting Layout Attributes 'no_lights' specified in Scene Attributes but does not exist in dataset, so creating default.

[16:14:25:364030]:[Warning]:[Sim] Simulator.cpp(594)::instanceStageForSceneAttributes : The active scene does not contain semantic annotations : activeSemanticSceneID_ = 0

Thanks in advance for your support!

Hello, any chance somebody can look into this? At the moment, we don't have a way to use Scannet in Habitat Sim. We have the following files for a scene:

In [21]: ls
scene0015_00.aggregation.json  scene0015_00_2d-instance-filt.zip  scene0015_00_2d-label.zip               scene0015_00_vh_clean.ply                   scene0015_00_vh_clean_2.glb         scene0015_00_vh_clean_2.ply
scene0015_00.sens              scene0015_00_2d-instance.zip       scene0015_00_vh_clean.aggregation.json  scene0015_00_vh_clean.segs.json             scene0015_00_vh_clean_2.labels.glb
scene0015_00.txt               scene0015_00_2d-label-filt.zip     scene0015_00_vh_clean.glb               scene0015_00_vh_clean_2.0.010000.segs.json  scene0015_00_vh_clean_2.labels.ply

and we try to create a simulator in this way:

import habitat_sim
from copy import deepcopy
from habitat_sim.utils.settings import default_sim_settings, make_cfg

settings = deepcopy(default_sim_settings)
settings.update(
          {
              "max_frames": 1000,
              "scene": "scene0015_00_vh_clean.glb",
              "color_sensor": True,
          }
 )
cfg = make_cfg(settings)
sim = habitat_sim.Simulator(cfg)

This raises the following error:

Could you please help?

@aclegg3 , @jturner65 : Would you have some context on this?

Our scannet dataset use instructions can be found here: https://github.com/facebookresearch/habitat-sim/blob/main/DATASETS.md#scannet (not sure if things have changed since this was written).

From what I see here, I would suggest you check the "scene" path: "scene": "scene0015_00_vh_clean.glb", This should actually be the relative path to the asset (from the working directory) unless you have a scene_dataset_config.json referencing the directory or paths to the assets within.

See https://aihabitat.org/datasets/replica_cad/ for an example of setting up SceneDataset configs.
