If you meet some errors like pyglet.canvas.xlib.NoSuchDisplayException: Cannot connect to "None", you must run this code on a server. You should follow this tutorial.

Install pyrender in a server:

1. Install osmesa with sudo

sudo apt update
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

2. Install pyopengl

mkdir -p 3rdparty
cd 3rdparty
git clone https://github.com/mmatl/pyopengl.git
python3 -m pip uninstall pyopengl
python3 -m pip install ./pyopengl
# add osmesa to environment variable
echo "export PYOPENGL_PLATFORM=osmesa" >> ~/.zshrc
export PYOPENGL_PLATFORM=osmesa

You must run export PYOPENGL_PLATFORM=osmesa once before you run any code on a server.

@LuPaoPao , could you solve the problem.

i'm getting pyglet.canvas.xlib.NoSuchDisplayException: Cannot connect to "None" and did what @chingswy said but still having the problem.

i leave here a colab showing my entire code:
