Waifu2x

Project Icon

Python 3.12 is not supported :(

Waifu2x is an image upscaling and noise reduction algorithm that gained popularity for its ability to enhance the quality of anime-style images. The implementation in Chainer, a deep learning framework, uses neural networks to perform the image enhancement tasks.

Documentation

A high-level overview of how the documentation is organized organized will help you know where to look for certain things:

  • Tutorials take you by the hand through a series of steps to get started using the software. Start here if you’re new.
  • The Technical Reference documents APIs and other aspects of the machinery. This documentation describes how to use the classes and functions at a lower level and assume that you have a good high-level understanding of the software.

Install With PIP

pip install waifu2x

Head to https://pypi.org/project/Waifu2x/ for more info

Language information

Built for

This program has been written for Python versions 3.8 - 3.11 and has been tested with both 3.8 and 3.11

Install Python on Windows

Chocolatey

choco install python

Windows - Python.org

To install Python, go to https://www.python.org/downloads/windows/ and download the latest version.

Install Python on Linux

Apt

sudo apt install python3.x

Dnf

sudo dnf install python3.x

Install Python on MacOS

How to run

Windows

  • Module py -3.x -m [module] or [module] (if module installs a script)

  • File py -3.x [file] or ./[file]

Linux/ MacOS

  • Module python3.x -m [module] or [module] (if module installs a script)

Building

This project uses https://github.com/FHPythonUtils/FHMake to automate most of the building. This command generates the documentation, updates the requirements.txt and builds the library artefacts

Note the functionality provided by fhmake can be approximated by the following

handsdown  --cleanup -o documentation/reference
poetry export -f requirements.txt --output requirements.txt
poetry export -f requirements.txt --with dev --output requirements_optional.txt
poetry build

fhmake audit can be run to perform additional checks

Testing

For testing with the version of python used by poetry use

poetry run pytest

Alternatively use tox to run tests over python 3.8 - 3.11

tox
