# Generate fauvism still life image using FastGAN

## Model description

[FastGAN model](https://arxiv.org/abs/2101.04775) is a Generative Adversarial Networks (GAN) training on a small amount of high-fidelity images with minimum computing cost. Using a skip-layer channel-wise excitation module and a self-supervised discriminator trained as a feature-encoder, the model was able to converge after some hours of training for either 100 high-quality images or 1000 images datasets.

This model was trained on a dataset of 124 high-quality Fauvism painting images.

#### How to use

```python
# Clone this model 
git clone https://huggingface.co/huggan/fastgan-few-shot-fauvism-still-life/

def load_generator(model_name_or_path):
    generator = Generator(in_channels=256, out_channels=3)
    generator = generator.from_pretrained(model_name_or_path, in_channels=256, out_channels=3)
    _ = generator.eval()

    return generator
    
def _denormalize(input: torch.Tensor) -> torch.Tensor:
    return (input * 127.5) + 127.5
    
# Load generator
generator = load_generator("fastgan-few-shot-fauvism-still-life")

# Generate a random noise image
noise = torch.zeros(1, 256, 1, 1, device=device).normal_(0.0, 1.0)
with torch.no_grad():
  gan_images, _ = generator(noise)
  
gan_images = _denormalize(gan_images.detach())
save_image(gan_images, "sample.png", nrow=1, normalize=True)
```

#### Limitations and bias

* Converge faster and better with small datasets (less than 1000 samples)
