This is a minimal implementation of DALL·E Mini. It has been stripped to the bare essentials necessary for doing inference, and converted to PyTorch. The only third party dependencies are numpy, torch, and flax (and optionally wandb to download the models). DALL·E Mega inference with PyTorch takes about 10 seconds in Colab.
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
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.
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
