Unable to initialize EGL about igibson HOT 10 CLOSED

@ahmedosman Hi, How did you solve your problem. Can you share your experience please?

from igibson.

I also meet the similar problem. I successfully pass all the tests but fail in running demo.py. The terminal information is as follows:
python demo.py

@ahmedosman Sorry, no. I use another virtual environment called "ai2thor" as a substitution.

@ahmedosman Can you try to install with USE_GLAD set to FALSE in https://github.com/StanfordVL/GibsonEnvV2/blob/master/gibson2/core/render/CMakeLists.txt and try again? Thanks.

@shsjxzh were you able to resolve this error?

@fxia22 The error is resolved (Ubuntu 18.04). I think this issue could be closed.

Hello! I am also still running into the same error "Unable to initialize EGL" on Ubuntu 18.04. I followed steps 1-3 of the troubleshooting guide and the output of my ldconfig -p | grep EGL is below:

libEGL_nvidia.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL_nvidia.so.0
libEGL_mesa.so.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL_mesa.so.0
libEGL.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libEGL.so.1

Tried setting USE_GLAD to FALSE but then ran into more build errors, i pasted the error part of the message below:

...
    [ 50%] Linking CXX executable /home/lisa/Documents/iGibson/gibson2/render/mesh_renderer/build/test_device
/usr/bin/ld: cannot find -lEGL
    collect2: error: ld returned 1 exit status

    make[2]: *** [/home/lisa/Documents/iGibson/gibson2/render/mesh_renderer/build/query_devices] Error 1
...

Any help would be appreciated.

Hi, we've recently updated the installation guide: http://svl.stanford.edu/igibson/docs/installation.html#system-requirements

The most common reasons we have discovered that reproduce this EGL issue are:

1. There is a bug with cgroups on certain versions of the nvidia 465.x and 450.x drivers that prevents opening an EGL context on all but GPU 0, please update, or have your cluster administrator update your nvidia driver.
2. You are missing libegl-dev (ubuntu/debian package)

Closing because I believe this was addressed with our latest documentation improvements. Please let us know if this is not the case.
