Segmentation fault (core dumped) when testing habitat-sim

[Wzey2000]

version

System: docker with Ubuntu 16.04.7 LTS

Habitat-Sim: v0.1.7, v0.3.0

Driver: NVIDIA-Linux-x86_64-470.57.02

ERROR

I ran habitat-sim v0.1.7 and habitat-lab v0.1.7 successfully before on the same server, but the server was accidentally reset, so I tried to reinstall habitat-sim v0.1.7 again.

It came out Segmentation fault (core dumped) when testing using examply.py with Non-interactive testing.

python examples/example.py --scene data/scene_datasets/mp3d/1LXtFkjw3qL/1LXtFkjw3qL.glb

I tried installing habitat-sim v0.1.7 using conda and building from source, both of them could install successfully but came out the same error when testing:

sim_cfg.physics_config_file = ./data/default.physics_config.json
==== Initialized Sensor Spec: =====
Sensor uuid:  color_sensor
Sensor type:  SensorType.COLOR

Segmentation fault (core dumped)

I reset the

export GLOG_minloglevel=2
export MAGNUM_LOG=quiet
export HABITAT_SIM_LOG=quiet

to get the details, then it came out:

python examples/example.py --scene data/scene_datasets/mp3d/1LXtFkjw3qL/1LXtFkjw3qL.glb

I also debugged the example.py, the error appeared when it ran the line

super().__init__(config.sim_cfg)

in

def _config_backend(self, config: Configuration) -> None:
    if not self._initialized:
        super().__init__(config.sim_cfg)        # ERROR !!!
        self._initialized = True
    else:
        super().reconfigure(config.sim_cfg)

which is in /path/to/anaconda/env//lib/python3.6/site-packages/habitat_sim-0.1.7-py3.6-linux-x86_64.egg/habitat_sim/simulator.py.

I also tried the latest version of habitat-sim, v0.3.0, using conda install. When testing, the same error came out again:

sim_cfg.physics_config_file = data/default.physics_config.json
Segmentation fault (core dumped)

By the way

The first bug I came across was the lack of libEGL.so etc, I solved these problems using #1511 as I did not have the permission to reinstall the driver:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/NVIDIA-Linux-x86_64-<version-id>

I dont know if it would cause the problem of Segmentation fault (core dumped).

❓ Questions and Help

I think this may be the problem of my server, because I ran successfully before.

Could you help me to identify the problem of my server or the direction to debug please?
