[Paper]

TODO

• Release inference code
• Release text-to-image generator at 64x64 resolution
• Release models at higher resolution
• Release training code
• Release plug-ins/efficient algorithms for more functionalities

Installation

This repository is developed based on Hammer, where you can find more detailed instructions on installation. Here, we summarize the necessary steps to facilitate reproduction.

1. Environment: CUDA version == 11.3.

2. Install package requirements with conda:

   conda create -n aurora python=3.8  # create virtual environment with Python 3.8
   conda activate aurora
   pip install -r requirements/minimal.txt -f https://download.pytorch.org/whl/cu113/torch_stable.html
   

Inference

First, please download the pre-trained model here.

To synthesize an image with given text prompt, you can use the following command

python run_synthesize.py aurora_v1.pth 'A photo of a tree with autumn leaves'

To make interpolation between two text prompts, you can use the following command

python run_interpolate.py aurora_v1.pth \
       --src_prompt 'A photo of a tree with autumn leaves' \
       --dst_prompt 'A photo of a victorian house'

Results

• Text-conditioned image generation

• Text prompt interpolation
