If you’re stepping into the exciting world of GANs (Generative Adversarial Networks) and you want to customize or create unseen objects with a distinctive shape, you’re in the right place. In this guide, we will walk you through the process of utilizing the innovative methods introduced in the project “Rewriting Geometric Rules of a GAN,” which enables users to warp images while preserving various visual features.
Introduction
This method allows users to interact with a GAN model to create customized representations of objects by simply defining a few control points. You can alter shapes while maintaining other aspects such as pose and color intact. If you’re excited to dive into this, let’s get started!
Getting Started
Here’s a step-by-step approach:
1. Clone the Repository
bash
git clone git@github.com:PeterWang512/GANWarping.git
cd GANWarping
git submodule update --init --recursive
2. Set Up the Conda Environment
bash
conda env create -f environment.yaml
conda activate ganwarp
3. Download Model Weights and Data
bash
# Download training data
bash data/download_data.sh
# Download pretrained models
bash pretrained/download_pretrained_models.sh
# Download edited models
bash weights/download_weights.sh
4. Explore Local Jupyter Notebooks
- compose_models.ipynb: Composes multiple prior edited models.
- generate_warp_data.ipynb: Generates training data to warp a GAN.
- generate_color_data.ipynb: Generates training data to change GAN colors.
5. Generating Samples from a Customized Model
Finally, you can run customized models using the command below:
# Generates samples
python sample.py -o results/samples -m weights/sg3r_catcat_alien_eye.pth --pretrained cat
# Generates a video of samples
python sample.py -o results/video.mp4 -m weights/sg3r_catcat_alien_eye.pth --pretrained cat --tile --video
Understanding the Code with an Analogy
Imagine you’re an artist sculpting a statue. Each command in the setup phase is similar to gathering the right tools and materials before you start shaping your masterpiece. When you clone the repo, it’s as if you’re obtaining a blank canvas. Setting up the conda environment is like preparing your workspace and ensuring you have all the necessary colors and brushes. Downloading model weights and data is akin to collecting your reference images and sculptures for studying the shapes. Finally, the generation commands represent each stroke of your chisel that brings the statue closer to life.
Troubleshooting
If you encounter issues during the setup or generation process, here are some troubleshooting ideas:
- Ensure that your GPU is correctly set up and compatible with the requirements specified in the repository.
- Check for any typos in the command line; often small errors can lead to significant problems.
- Verify that all model weights and data have been downloaded properly.
