EGL lib issue

[gilbertoyw]

Hello, thanks for sharing this code.

I've tried to run it on Windows 11 and Ubuntu 20.4, and I've got the same issue after executing the demo.py (see below). Can you help me?

(multihmr) PS C:\Users\gilbe\multi-hmr> python demo.py --img_folder example_data --out_folder demo_out --extra_views 1 --model_name multiHMR_896_L
Traceback (most recent call last):

self._handle = _dlopen(self._name, mode)
FileNotFoundError: ("Could not find module 'EGL' (or one of its dependencies). Try using the full path with constructor syntax.", 'EGL', None)

During handling of the above exception, another exception occurred:

Hi @gilbertoyw , thanks for your interest in our work.
It seems that your code is not able to load EGL library which is used for doing the rendering in our demo code.
Please have look to this related issue.
In Ubuntu you need to install OpenGL using the following command lines.
Hope it helps,

Thank you very much @fabienbaradel I will follow this thread.

Great, since it is not directly related to Multi-HMR I am closing this issue. Feel free to ask to re-open it.
Good luck!

I only commented out line 6 and it worked for me on Windows:
# os.environ["PYOPENGL_PLATFORM"] = "egl"
