## Requirements

If you have CUDA graphic card, please follow the requirements of [NVlabs/stylegan3](https://github.com/NVlabs/stylegan3#requirements).  

The usual installation steps involve the following commands, they should set up the correct CUDA version and all the python packages

```
conda env create -f environment.yml
conda activate stylegan3
```

Then install the additional requirements

```
pip install -r requirements
```

Otherwise (for GPU acceleration on MacOS with Silicon Mac M1/M2, or just CPU) try the following:

```sh
cat environment.yml | \
  grep -v -E 'nvidia|cuda' > environment-no-nvidia.yml && \
    conda env create -f environment-no-nvidia.yml
conda activate stylegan3

# On MacOS
export PYTORCH_ENABLE_MPS_FALLBACK=1
```

## Run Gradio visualizer in Docker 

Provided docker image is based on NGC PyTorch repository. To quickly try out visualizer in Docker, run the following:  

```sh
docker build . -t draggan:latest  
docker run -p 7860: 7860 -v "$PWD":/workspace/src -it draggan:latest bash  
cd src && python visualizer_drag_gradio.py --listen
```
Now you can open a shared link from Gradio (printed in the terminal console).   
Beware the Docker image takes about 25GB of disk space!

## Download pre-trained StyleGAN2 weights

To download pre-trained weights, simply run:
```sh
sh scripts/download_model.sh
```
Or for windows:
```
.\scripts\download_model.bat
```
If you want to try StyleGAN-Human and the Landscapes HQ (LHQ) dataset, please download weights from these links: [StyleGAN-Human](https://drive.google.com/file/d/1dlFEHbu-WzQWJl7nBBZYcTyo000H9hVm/view?usp=sharing), [LHQ](https://drive.google.com/file/d/16twEf0T9QINAEoMsWefoWiyhcTd-aiWc/view?usp=sharing), and put them under `./checkpoints`.

Feel free to try other pretrained StyleGAN.

## Run DragGAN GUI

To start the DragGAN GUI, simply run:
```sh
sh scripts/gui.sh
```
If you are using windows, you can run:
```
.\scripts\gui.bat
```

This GUI supports editing GAN-generated images. To edit a real image, you need to first perform GAN inversion using tools like [PTI](https://github.com/danielroich/PTI). Then load the new latent code and model weights to the GUI.

You can run DragGAN Gradio demo as well, this is universal for both windows and linux:
```sh
python visualizer_drag_gradio.py
```
