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

Open EftePA opened this issue 1 year ago • 2 comments

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):

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.

Hey @EftePA ,

I'm glad to hear this is working! It can be a pain that CUDA drivers compile behind the scenes and may require a system restart to take affect.

I'm going to close this issue because the original problem is solved.

now example.py inside habitat-sim is working (but not the example.py in habitat-api)! It is worth noting that habitat-api is no longer a functioning repo. It was converted to habitat-lab.
