Gibson dataset glb files

Habitat-Sim version

v0.2.1

❓ Questions and Help

I have downloaded the gibson tiny dataset from here as gibson_tiny.tar.gz which contained some obj files and others for each scene but no glb files. I then downloaded the 3DSceneGraph and then converted it via tools/gen_gibson_semantics.sh /path/to/3DSceneGraph_medium/automated_graph /path/to/GibsonDataset /path/to/output which produced some scns and ids. But I need the glb files for the scenes to run the demo notebook and I don't understand how or where to obtain those. Any directions on how to get those glb files?

You can find some detail on using Gibson here: https://github.com/facebookresearch/habitat-sim/blob/main/DATASETS.md#gibson-and-3dscenegraph-datasets

They should provide some habitat-ready files. From the download page:

C. To use with Habitat-sim/challenge (ICCV 2019)

Gibson Dataset for Habitat (11GB): gibson_habitat_trainval.zip gibson_habitat.zip

In general, Habitat can support .obj files, but typically .glb are better. Habitat-ready datasets are typically also compressed to allow faster import and simulation.

Thank you for responding. The demo notebook is using the gibson_tiny split. Will the gibson_habitat.zip you mentioned also have the same scene files?

I believe the habitat version should contain all the original gibson splits. If that doesn't end up being the case please let me know here.

Yes, downloading the habitat version indeed solved the issue. The scene is successfully loaded but when I try to get the objects from semantic scene scene_objects = sim.semantic_scene.objects it returns none. The full code is here.
