Dear author:
When I try to run "run_nerf.py", It shows the following problems:
" File "/home/user/dxf/HNR-VLN-main1/habitat-lab/habitat/core/embodied_task.py", line 275, in _init_entities

and

    Do you have any suggestions?

You can run the following command in the directory where run_nerf.py is located: bash run_r2r/nerf.bash train 2345 for pre-training.
Additionally, due to the enormous size of the data from 900 scenes, loading speed can be significantly slow, which might hinder code debugging. You can try modifying if count == 5: break in habitat_extensions/task.py to adjust the number of scenes loaded for quicker code debugging.
