How can I run this program?

  • 772

I was looking for an origami simulation program (can simulate a piece of paper and fold) and I found the following: https://www.youtube.com/watch?v=1TAOKIRV2d4 It looks very nice so I tried to use it... but I couldn't. and I don't why. I get the following message error: 

ImportError: No module named visual

And I have python and vpython. Also I tried to change the line of code:

import visual * for

import vpython *

of the .py script but it wasn't effective.

Can you help me to run this program in ubuntu please? or do you know another good origami simulation program I can use in Ubuntu?

EDIT 1. According to the comment by @Dimitrios Zacharatos I typed

pip install vpython and got the following:

Command 'pip' not found, but can be installed with:
sudo apt install python-pip

So I did it and again typed:

pip install vpython

This time at the end of the process I got the following warning:

jupyter-server-proxy requires Python '>=3.5' but the running Python is 2.7.17
python

  1. You need to install and use python3-pip

    sudo apt install python3-pip
pip3 install vpython
