How to use it in Google colab?

hangs without render anything. I do the following steps to install the environment:

!apt install curl
!curl -sL https://deb.nodesource.com/setup_10.x | bash -
!apt-get install -y nodejs
!node -v
!pip install vpython
!jupyter labextension install vpython

What (if anything) do you see if instead of making a box you say print(version)? Are you working within an Anaconda environment, which is recommended? If you are in Anaconda, it is recommended to execute "conda install -c vpython vpython" rather than pip.

still not render :(

!wget -c https://repo.anaconda.com/miniconda/Miniconda3-4.5.4-Linux-x86_64.sh
!chmod +x Miniconda3-4.5.4-Linux-x86_64.sh
!bash ./Miniconda3-4.5.4-Linux-x86_64.sh -b -f -p /usr/local
!yes | conda install -c vpython vpython
import sys
sys.path.append('/usr/local/lib/python3.6/site-packages')
!python -V

$Python 3.6.5 :: Anaconda, Inc.

import vpython 
vpython.__version__

$'7.6.1'

Okay, the next thing to test is to go to https://get.webgl.org. You should see a rotating box and a title "Your browser supports WebGL". (WebGL is the 3D graphics library built into modern browsers, which VPython uses to do the 3D rendering.) A closely related issue is that your graphics card must be capable of executing GPU code. What browser do you use?

in my pc runs perfectly, the problem is only in google colab

[okadath]

this is in my laptop, Mozilla Firefox, but in google colab not renderize yet :(

Sorry, I didn't read carefully enough to know that the problem occurs ONLY in Jupyter lab. I'll ask a colleague about this.

[okadath]

Thank you very much for answering

[BruceSherwood]

I apologize that although you kept saying "colab" I kept thinking "lab". While VPython does run in Jupyter lab, it does not (yet) run in colab, Our expert on Jupyter lab has looked into colab but has not found a way to make VPython work there.
