Platform::WindowlessEglApplication::tryCreateContext(): unable to find CUDA device 0 among 2 EGL devices in total

[28dvd28]

Hello, I'm trying to use habitat-sim for my project, but when i'm running it i'm getting the error: Platform::WindowlessEglApplication::tryCreateContext(): unable to find CUDA device 0 among 2 EGL devices in total I've looked in some other already opened issue, but I can't find a solution, maybe also because i'm working on a WSL and not directly on linux machine.

The fact that i am using the WSL can it be the reason of why I'm getting the error? If yes can you help me solving this?

Hey @28dvd28

I assume this can work, but it sounds like you'll need to do some work to expose and setup the GPU correctly.

I saw this: https://canonical-ubuntu-wsl.readthedocs-hosted.com/en/latest/tutorials/gpu-cuda/

Also take a look at our troubleshooting guide for graphics issues.

Once you've dug in a bit and can provide some more info maybe myself or @0mdc can help with any questions.

Hello,

many thanks for the resources that you gave me.

I've looked at both the link that you have sent to me. From the first one I have a question. I need to download the nvidia driver for windows. But i've already done it for gaming, so i downloaded the game ready driver (I think, it has been i while). Do I need to download the Studio Driver?

I've looked to the second link and i've followed the instruction, but i don't know if i have the right output, so:

• running eglinfo I get Above is a lot of more output, similar to the last lines and then I get Device platofrom without nothing, is it a problem? -apt list --installed | grep libglvnd get me is it ok? -I had to create the file _10nvidia.json in _/usr/share/glvnd/eglvendor.d/, the path that i have to put in "librarypath" must be like "../../../../lib/x8664-linux-gnu/libEGL.so.1" or like _"lib/x8664-linux-gnu/libEGL.so.1"?

In any case i am still having the issue also testing it in the habitat-lab reposotory with the command python examples/example.py. Hope you will be able to help me.

Kind regards

Hello @28dvd28 - did you managed to find a fix for this? I am literally having the same issue as you are.

I can run the provided example examples/viewer.py with the skokloster-castle.glb example, but cannot get it to work with Matterport3D dataset (after following the Matterport3D instructions).

nvidia-smi and nvcc --version are all returning up-to-date drivers and toolkit. I also get the same eglinfo: eglInitialize failed after a wall of text.

Hoping someone has a fix as I can't seem to find many solved problems online...

Hello @wsychiu, I wasn't able to solve this issue, I think that maybe for some strange reason it is needed a full Linux OS on your machine and with just the WSL, for some strange reason, it is not working.

Thanks @28dvd28 - did you get it working on a full Linux install?

[28dvd28]

@wsychiu - Since it was a school project, I thought that it was too much effort change the OS of my PC, so i did not go on trying to solve it, but the PhD student, that was following me on this project, used a Linux OS and on his PC everything worked fine.
