I met this bug

ok， It seems that there has some elusive bug with the egl. According to the docs of pyrender, we can use osmesa instead of egl.

change
os.environ['PYOPENGL_PLATFORM'] = 'egl'
into
os.environ['PYOPENGL_PLATFORM'] = 'osmesa'
to use osmesa.
see the docs to learn how to install osmesa.

sudo apt update
sudo apt-get install llvm-6.0 freeglut3 freeglut3-dev
sudo apt --fix-broken install
sudo wget https://github.com/mmatl/travis_debs/raw/master/xenial/mesa_18.3.3-0.deb
sudo dpkg -i ./mesa_18.3.3-0.deb || true
sudo apt install -f

or
sudo wget --no-check-certificate https://github.com/mmatl/travis_debs/raw/master/xenial/mesa_18.3.3-0.deb

then

git clone https://github.com/mmatl/pyopengl.git
pip install ./pyopengl

if get this error:

output_img = rgb[:, :, :-1] * valid_mask + (1 - valid_mask) * img
ValueError: operands could not be broadcast together with shapes (1080,1920,2) (1080,1920,3)

change output_img = rgb[:, :, :-1] * valid_mask + (1 - valid_mask) * img into output_img = rgb[:, :, :] * valid_mask + (1 - valid_mask) * img or output_img = rgb * valid_mask + (1 - valid_mask) * img
