Unable to create windowless context while running example.py in habitat-sim

[EftePA]

Following the tutorials, I've created a virtual environment and installed habitat-api, habitat-lab, and habitat-sim inside it. And I could get the following examples running:

• Interactive testing, i.e.,: python examples/viewer.py --scene ./data/scene_datasets/habitat-test-scenes/skokloster-castle.glb.
• Physical interactions, i.e.,: python examples/viewer.py --dataset data/replica_cad/replicaCAD.scene_dataset_config.json --scene apt_1

However, running python examples/example.py inside hapitat-sim returns:

sim_cfg.physics_config_file = data/default.physics_config.json
Platform::WindowlessEglApplication::tryCreateContext(): unable to find CUDA device 0 among 3 EGL devices in total
WindowlessContext: Unable to create windowless context

Tried this solution, it didn't help.

Any idea what I've made wrong and how I can fix it to get example.py inside habitat-sim running? Thank you.

Some other info:

1. Running python examples/example.py inside hapitat-api returns:

Traceback (most recent call last):
  File "/home/.../habitat-api/examples/example.py", line 9, in <module>
    import habitat.gym  # noqa: F401
ModuleNotFoundError: No module named 'habitat'

2. Running echo $(cd examples; python -c "import habitat_sim; print(habitat_sim.__file__)") inside habitat-sim returns:

home/.../miniconda3/envs/habitat/lib/python3.9/site-packages/habitat_sim-0.3.0-py3.9-linux-x86_64.egg/habitat_sim/__init__.py

3. Running ldconfig -N -v | grep libEGL returns:

Does anyone know where the "WindowlessContext: Unable to create windowless context" issue might come from. I reinstalled the NVIDIA drivers and that did not work.

Thanks in advance

I had not restarted my system after installing CUDA Toolkit. Today, by accident, I restarted, and now example.py inside habitat-sim is working (but not the example.py in habitat-api)!
These are the steps I've took to install cuda toolkit 12.4 on Ubuntu 22:

Base Installer:

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-ubuntu2204.pin
sudo mv cuda-ubuntu2204.pin /etc/apt/preferences.d/cuda-repository-pin-600
wget https://developer.download.nvidia.com/compute/cuda/12.4.0/local_installers/cuda-repo-ubuntu2204-12-4-local_12.4.0-550.54.14-1_amd64.deb
sudo dpkg -i cuda-repo-ubuntu2204-12-4-local_12.4.0-550.54.14-1_amd64.deb
sudo cp /var/cuda-repo-ubuntu2204-12-4-local/cuda-*-keyring.gpg /usr/share/keyrings/
sudo apt-get updatesudo apt-get -y install cuda-toolkit-12-4

Driver Installer

sudo apt-get install -y cuda-drivers

Hope helps others.
