min(DALL·E)

   

This is a minimal implementation of Boris Dayma's DALL·E Mini in PyTorch. It has been stripped to the bare essentials necessary for doing inference. The only third party dependencies are numpy, requests, pillow and torch.

It currently take 35 seconds to generate a 3x3 grid with DALL·E Mega on a standard GPU runtime in Colab.

The flax model and code for converting it to torch can be found here.

Install

$ pip install min-dalle

Usage

Python

Load the model parameters once and reuse the model to generate multiple images.

from min_dalle import MinDalle

model = MinDalle(is_mega=True, models_root='./pretrained')

The required models will be downloaded to models_root if they are not already there. Once everything has finished initializing, call generate_image with some text and a seed as many times as you want.

text = 'a comfy chair that looks like an avocado'
image = model.generate_image(text)
display(image)

text = 'court sketch of godzilla on trial'
image = model.generate_image(text, seed=6, grid_size=3)
display(image)

Command Line

Use image_from_text.py to generate images from the command line.

$ python image_from_text.py --text='artificial intelligence' --seed=7

$ python image_from_text.py --text='trail cam footage of gollum eating watermelon' --mega --seed=1 --grid-size=3
