Overview

Generative Art Using Neural Visual Grammars and Dual Encoders

Arnheim 1

The original algorithm from the paper Generative Art Using Neural Visual Grammars and Dual Encoders running on 1 GPU allows optimization of any image using a genetic algorithm. This is much more general but much slower than using Arnheim 2 which uses gradients.

Arnheim 2

A reimplementation of the Arnheim 1 generative architecture in the CLIPDraw framework allowing optimization of its parameters using gradients. Much more efficient than Arnheim 1 above but requires differentiating through the image itself.

Usage

Usage instructions are included in the Colabs which open and run on the free-to-use Google Colab platform - just click the buttons below! Improved performance and longer timeouts are available with Colab Pro.

The README says:

I am slightly confused as to what this means.

Can arnheim_2.ipynb be used under the terms of the Apache 2.0 license? Is CLIPDraw provided under the Apache 2.0 license?

Kernel keeps on dying when trying arnheim_3.ipynb

When trying to run arnheim_3.ipynb on local machine, the kernel keeps on dying when executing output = ct.loop(). There no errors before this piece of code. Could you please tell me how to resolve it?

Tried arnheim2.ipynb - See Error

Cell "Preliminaries" works fine in Colab. The next cell throws an error:

`Torch version: 1.9.0+cu111

AttributeError Traceback (most recent call last)

in () 18 19 import clip ---> 20 import pydiffvg 21 22 os.environ["FFMPEG_BINARY"] = "ffmpeg"

AttributeError: module 'diffvg' has no attribute 'FilterType' `

Never mind. Can close. I didn't see step 4. Best if you can get the user to click on a button to restart run time in the cell flow.
