min(DALL·E)

 

This is a minimal implementation of Boris Dayma's DALL·E Mini. It has been stripped to the bare essentials necessary for doing inference, and converted to PyTorch. To run the torch model, the only third party dependencies are numpy and torch. Flax is used to convert the weights (which can be saved with torch.save once the model is loaded), and wandb is only used to download the models.

It currently takes 7.3 seconds to generate an avocado armchair with DALL·E Mega in PyTorch on Colab (with nonexpendable model in high RAM runtime)

Setup

Run sh setup.sh to install dependencies and download pretrained models. The models can also be downloaded manually here: VQGan, DALL·E Mini, DALL·E Mega

Usage

Use the python script image_from_text.py to generate images from the command line. Note: the command line script loads the models and parameters each time. To load a model once and generate multiple times, initialize either MinDalleTorch or MinDalleFlax, then call generate_image with some text and a seed. See the colab for an example.

Examples

python image_from_text.py --text='artificial intelligence' --torch

python image_from_text.py --text='a comfy chair that looks like an avocado' --torch --mega --seed=10

python image_from_text.py --text='court sketch of godzilla on trial' --mega --seed=100
