In CVPR 2021

Prerequisites

• Linux
• Python 3
• NVIDIA GPU + CUDA CuDNN

Setup

• Clone this repo:

git clone https://github.com/BERYLSHEEP/AdvStyle.git

• Download resources:
  • Please download the pretrained FFHQ StyleGAN and anime StyleGAN weights
  • Move the weights to models/pretrain/pytorch

Testing Demo

The following commands are examples of testing the learned direction:

# stylegan ffhq
python new_demo.py manipulate_test supermodel \
				--gan_model stylegan_ffhq --resolution 1024 --latent_type z
	
# stylegan anime
python new_demo.py manipulate_test maruko \
				--gan_model stylegan_anime --resolution 512 --latent_type z

if you want to manipulate multi attributes simultaneously, you can list all the attributes on the command as follow:

# multi attribute manipulation
python new_demo.py manipulate_test blonde,open_mouth \
				--gan_model stylegan_anime --resolution 512 --latent_type z

If you want to specific the manipulated latent code, you can set the --noise_path option:

# specific latent code
python new_demo.py manipulate_test maruko \
				--gan_model stylegan_anime --resolution 512 --latent_type z \
				--noise_path ./noise/maruko/2.npy

Results are saved to result/{attribute}

The attribute names are the file names in the boundaries directory.

Interactive Demo

• Prerequisites: Flask

  pip install flask
  pip install --upgrade flask_nav
  pip install --upgrade flask_bootstrap
  

• Running

  # only for stylegan_anime
  # the input latent code is belong to latent space z [1, 512]
  python app.py --latent_code noise/maruko/16.npy --composing_type z
  # the input latent code is belong to latent space w+ [1, 16, 512]
  python app.py --latent_code noise/38_w+.npy --composint_type w+
  

• Instructions

  • Only one attribute can be edited at once time.
  • Multi attributes edit examples:
    • Click the corresponding Edit Button for "Pink Hair", then move the corresponding toolbar to the desired step.
    • Click the corresponding Edit Button for "Open Mouth", then move the corresponding toolbar to the desired step.
    • ....
