[BUG] Unable to load EGL library #101

mayoudong1993 · 2020-07-05T18:43:11Z

My operation system is Windows 10, and my GPU driver is GeForce Game Ready Driver. I got this error below, could you give me some hints, what's this error talking about?

Traceback (most recent call last):

Hi @mayoudong1993,

We didn't test our code on Windows, so it is a bit difficult to figure out the problem. And it seems the problem is related to pyrender installation, so I would suggest you to refer pyrender docs/issues to find a solution.

polar99 · 2020-07-27T07:49:31Z

@mkocabas @mayoudong1993 This problem should not be from pyrender. The biggest problem is the code : os.environ['PYOPENGL_PLATFORM'] = 'egl' in demo.py.
It will use EGL as OpenGL Platform. So when initializing opengl, the problem
raise ImportError("Unable to load EGL library", *err.args)
occured.

(1) About EGL on Windows system
In fact, there is nothing like egl.dll in python\Lib\site-packages\OpenGL\DLLS, so it can't load EGL library.

(2) As for pyrender
Pyrender\offscreen.py

def _create(self):
     if 'PYOPENGL_PLATFORM' not in os.environ:
         from pyrender.platforms.pyglet_platform import PygletPlatform
         self._platform = PygletPlatform(self.viewport_width,
                                         self.viewport_height)
     elif os.environ['PYOPENGL_PLATFORM'] == 'egl':
         from pyrender.platforms import egl
         device_id = int(os.environ.get('EGL_DEVICE_ID', '0'))
         egl_device = egl.get_device_by_index(device_id)
         self._platform = egl.EGLPlatform(self.viewport_width,
                                          self.viewport_height,
                                          device=egl_device)

The default is PygletPlatform.
So just comment os.environ['PYOPENGL_PLATFORM'] = 'egl' in demo.py.
It works well on my experiment. (Win10 64 bit)

Thanks @stephengreat for the solution. Is this the only modification you did to make VIBE work on Windows?

polar99 · 2020-08-03T00:36:52Z

Thanks @stephengreat for the solution. Is this the only modification you did to make VIBE work on Windows?

You need to install ffmpeg (windows latest version) which can download from official website. Put ffmpeg.exe in system variable Path.
Other settings are same as requirements.txt https://github.com/mkocabas/VIBE/blob/master/requirements.txt
Any questions are welcome.

After commenting this line I got this error: "ValueError: Failed to initialize Pyglet window with an OpenGL >= 3+ context. If you're logged in via SSH, ensure that you're running your script with vglrun (i.e. VirtualGL). The internal error message was "Cannot connect to "None"". I'm trying to render the results on a ubuntu server.

Hi, # apt-get install libosmesa6-dev freeglut3-dev fixes the issue.

comment os.environ['PYOPENGL_PLATFORM'] = 'egl' is effective, but it doesn't seem to be the main reason. I fixed it by install pyglet==1.5.24. And 1.5.20 or newer 2.0.0 all have error of no GLU or Unable to load EGL.

stevejaehyeok · 2022-11-18T08:06:12Z

sudo apt-get install libglfw3-dev libgles2-mesa-dev
This saved my life

I have installed ffmpeg.exe, and passed the CMD test, but there is still an ImportError: ('Unable to load EGL library', "Could not find module 'EGL' (or one of its dependencies). Try using the full path with constructor syntax.", 'EGL', None)
I am using the script from https://github.com/eth-siplab/AvatarPoser
thanks for your help

Hi, may I ask how you installed pyglet==1.5.24? I tried downloading it using the source code zip folder, but it still has the same GLUE and EGL issues. Thanks!

Anyone have any idea how to fix this on Windows 11.
