It's strange that I was able to run well before, and suddenly this problem occurred. now I have tried different versions of pyrender, searched Google, and still can't solve it.

I meet the same problem

The steps as follows can solve the problem:

sudo apt update
sudo apt-get install llvm-6.0
sudo apt-get install libsm6 libxrender1 libfontconfig1 freeglut3-dev
sudo apt --fix-broken install

wget https://github.com/mmatl/travis_debs/raw/master/xenial/mesa_18.3.3-0.deb
dpkg -i ./mesa_18.3.3-0.deb || true
apt install -f
git clone https://github.com/mmatl/pyopengl.git
pip install ./pyopengl

Because of Off-screen rendering, at last, you need to change "os.environ['PYOPENGL_PLATFORM'] = 'egl'" into "os.environ['PYOPENGL_PLATFORM'] = 'osmesa'" ，

Hi,

Thanks a lot!

I tried this but then I got 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)

Any idea about this error? Deepest thanks for your reply!

[xiezhongzhao]

@lulindeng you can change "rgb[:, :, :-1]" into "rgb[:, :, :]"，the error will disappear, good luck

[lulindeng]

@lulindeng you can change "rgb[:, :, :-1]" into "rgb[:, :, :]"，the error will disappear, good luck

@xiezhongzhao It works, thanks a lot!

[Gzzgz]

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

changed: output_img = rgb * valid_mask + (1 - valid_mask) * img

good luck!

How can I fix this on centos ?

[wsywsywsywsywsy979]

os.environ['PYOPENGL_PLATFORM'] = 'osmesa'

hi, I meet a new error：“AttributeError("'GLXPlatform' object has no attribute 'OSMesa'",)” after fixing according your solution , could you give me some advice?
