0. Notes

Basically, I am working on Linux. I sometimes check to make sure that this code works in Windows.

I am not familiar with Windows or Anaconda. If you are familiar with Anaconda, do it your way.

Easy way to install

1. Install Python

Install Python 3.10 from Windows Store.

2. Run installer

Run Installer for Windows.bat.

If you want to reinstall, delete venv folder and run it again.

If you have Anaconda installed, make sure you have added python to PATH. If python command opens Windows Store, see https://stackoverflow.com/questions/58754860/cmd-opens-windows-store-when-i-type-python.

3.2 Run waifu2x GUI

Run Run waifu2x GUI.bat.

3.2 Run waifu2x web interface

Run Run waifu2x Web.bat.

Open http://localhost:8812/

3.2 Open CLI Prompt

Run Open Prompt.bat.

Manually install

1. Install dependencies packages (Optional)

Install ImageMagick

NOTE: ImageMagick(wand) is only required for training and benchmark.

See Install ImageMagick on Windows.

Install libraqm.dll

NOTE: libraqm is only required for synthetic training data generation.

Download libraqm‑0.7.1.dll.zip from https://www.lfd.uci.edu/~gohlke/pythonlibs/#pillow .

See https://stackoverflow.com/questions/62939101/how-to-install-pre-built-pillow-wheel-with-libraqm-dlls-on-windows

2. Clone

git clone https://github.com/nagadomi/nunif.git
cd nunif

If you want to use the dev branch, execute the following command.

git clone https://github.com/nagadomi/nunif.git -b dev

or

git fetch --all
git checkout -b dev origin/dev

3. Setup venv (optional)

python -m venv venv
.\venv\Scripts\activate

4. Install Pytorch

pip install -r requirements-torch.txt

5. Install pip packages

pip install -r requirements.txt

If you want to use GUI,

pip install -r requirements-gui.txt

6. Run waifu2x.web

Download pre-trained models.

python -m waifu2x.download_models

Generate waifu2x/web/public_html

python -m waifu2x.web.webgen

Start the web server.

python -m waifu2x.web

Open http://localhost:8812/

If you got ImportError: cannot import name '_imagingcms' from 'PIL' error, upgrade the pillow package.

pip install --upgrade pillow

This seems to be a problem with the pillow that is installed by conda by default.
