ResourceManager.cpp:483] Check failed: Cr::Utility::Directory::exists(physicsFilename); Aborted (core dumped)

🐛 Bug

I am following the tutorial "rigid_object_tutorial.py". It was strange to me that when I cd into the habitat-sim/examples/tutorials directory, and run

python rigid_object_tutorial.py

I get the error:

F0818 11:19:36.033696  6052 ResourceManager.cpp:483] Check failed: Cr::Utility::Directory::exists(physicsFilename) 
*** Check failure stack trace: ***
Aborted (core dumped)

However, when I am outside of the examples/tutorials directory and run it (as suggested on the Doc),

python path/to/habitat-sim/examples/tutorials/rigid_object_tutorial.py

I don't get that error.

Why would this happen? I wouldn't expect the program's output would be different because of the path it is being run from.

Command

# command that you run

To Reproduce

Steps to reproduce the behavior:

1. cd into the habitat-sim/examples/tutorials directory
2. python rigid_object_tutorial.py (Get the error)
3. python path/to/habitat-sim/examples/tutorials/rigid_object_tutorial.py (no error)

Expected behavior

No error in both cases.

I see. There is a configuration parameter, in examples/settings

"physics_config_file": "./data/default.phys_scene_config.json",

It's set to be relative to the root directory of habitat-sim repository.

[Skylion007]

Yeah, we may want to update that via our gitpython hack for finding the root directory of Habitat-Sim that we use in the colab tutorials.

[Skylion007]

BTW, we haven't advertised it yet because we haven't transferred the text from the RST, but that particular tutorial is available in colab: https://colab.research.google.com/github/facebookresearch/habitat-sim/blob/master/examples/tutorials/colabs/rigid_object_tutorial.ipynb

[zkytony]

Cool, thanks for the colab link. It's fine now when I set my own physics_config_file parameter!
