Platform::WindowlessEglApplication::tryCreateContext(): cannot get default EGL display: EGL_BAD_PARAMETER

[robo-alex]

I tried to render data from Replica dataset with python examples/example.py --scene I have installed the Habitat with

conda create -n habitat python=3.6 cmake=3.14.0
conda activate habitat

Then I got the error:

Platform::WindowlessEglApplication::tryCreateContext(): cannot get default EGL display: EGL_BAD_PARAMETER
WindowlessContext: Unable to create windowless context

Could you please help me to solve this issue?

[erikwijmans]

Please run again with export MAGNUM_LOG=verbose MAGNUM_GPU_VALIDATION=ON

[robo-alex]

Please run again with export MAGNUM_LOG=verbose MAGNUM_GPU_VALIDATION=ON

I have tried this. Unfortunately, it seems not to work and the same bugs still exist.

[erikwijmans]

Is there no additional information printed? If so that likely indicates a driver bug or similar.

I tried

Sorry I am not sure if this if of a driver bug or not.

[erikwijmans]

Likely a driver issue. Headless mode requires a recent(ish) nvidia gpu with nvidia's opengl libraries (those are installed by default with a default driver install).

I see. Would you please tell me if there is anything I can do to handle the driver issue? Do I need to install the OpenGL lib manually?

[erikwijmans]

You shouldn't need to manually install them, they are installed as part of a normal driver install

I’m still confused because there are nvidia gpus on my cluster. I suppose the libraries are installed by default. But the driver issue still exists.

[erikwijmans]

Possibly not. Others have opened issues here because their cluster admins did not install nvidia's opengl libs. Please talk to them.

Sure. I really appreciate for your help!

[aclegg3]

This issue seems to be resolved.

Just in case someone needs this: here is a solution for those who don't want to use docker and happen to use a server that does not install EGL* along with NVIDIA driver by default. (cross-posted to https://github.com/facebookresearch/habitat-sim/issues/851 as well!)

1. run nvidia-smi to check the version of your driver
2. download the driver installation binary from NVIDIA directly. You can do this by searching nvidia driver <version-id> on google. The file should be NVIDIA-Linux-x86_64-<version-id>.run
3. extract the binary without running. This will create a folder named NVIDIA-Linux-x86_64-<version-id>

sh NVIDIA-Linux-x86_64-<version-id>.run --extract-only   

4. create some simlinks

cd NVIDIA-Linux-x86_64-<version-id>
ln -s ./libEGL.so.<version-id>  libEGL.so.1 # note: there might be a libEGL_nvidia*, do not symlink it as libEGL.so.1 instead!
ln -s ./libGL.so.<version> libGL.so.1      

5. Add this folder to your LD search path

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

6. Check your habitat linker (Thanks @erikwijmans for this!)

cd
ldd $(python -c "import habitat_sim; print(habitat_sim._ext.habitat_sim_bindings.__file__)")

Note that libEGL.so.1, libOpenGL.so.0 and libGLdispatch.so.0 should be all pointed to the ones in /path/to/NVIDIA-Linux-x86_64-<version-id>.

7. You're good to go! Just follow this to verify your habitat-sim installation.

[dhruvbatra]

Thanks @jeasinema for this. Would you mind sending a PR to add this information to https://github.com/facebookresearch/habitat-sim/blob/main/BUILD_FROM_SOURCE.md#common-build-issues

[gdg94]

@jeasinema Hi, thanks for the information! I'm trying to manually install the missing EGL libraries as you mentioned above. I have driver version 515.105.01 installed (without opengl support). I see in the NVIDIA-Linux-x86_64-<driver_version> folder that there is libEGL_nvidia.so.<driver_version>, do I need to symlink this too?

Update: I additionally added the symlink on libEGL_nvidia.so.<driver_version> to libEGL_nvidia.so.0. I can confirm that the method above by @jeasinema works well to resolve the issue (without asking admin to update opengl support). Thanks a lot!

That seems like I still can not run well. Following is my wrong message. That seems like Ican not use opencv now.
