simulation demo

Is there any checkpoints which I can evaluate directly?
How to generate demos in simulation as you show in the project website?

Hi @leyuan-sun, you can run navigation as described here after having downloaded the HM3D data.

Then can I get the visulization results not only the quantitative results? As you shown in the project webpage:Imitate (sim): Some areas in the simulator may appear to be navigable when they are blocked by an obstacle.

Yes, check the output dir for the visualization videos

Why the vis folder is empty? video works. I already set plot: True
save_vis: True

When I try main.py, "Annotation file found: data/hm3d_v0.2//val/hm3d_annotated_val_basis.scene_dataset_config.json
Completed with success status: TypeError: expected np.ndarray (got NoneType) in main.py #132", any ideas? thanks!!
