FileNotFoundError: [Errno 2] No such file or directory: 'data/hab3_bench_assets/episode_datasets/small_large.json.gz'

Steps to Reproduce

Steps to reproduce the behavior:

1. Follow the installation in the README of habitat-lab
2. Follow the humanoids_tutorial.ipynb under example/ till "env = init_rearrange_env(agent_dict, action_dict)"

Please note that without a minimal working example to reproduce the bug, we may not be able to help you.

Expected behavior

env is init and I can step forward to the tutorial

Additional context

[xavierpuigf]

You can find the dataset here: https://huggingface.co/datasets/ai-habitat/hab3_bench_assets/tree/main/episode_datasets
It can be downloaded using the command:

python -m habitat_sim.utils.datasets_download --uids hab3_bench_assets

Will update the tutorial to show that.
