You need to download the pre-trained models with the following command.

python -m waifu2x.download_models

This command is missing from the installation documentation. I have fixed it internally and will push in a few days.

This is also a problem that occurs only on Windows.

I have fixed all the issues you reported, including this one, but I have 100+ changes in the private repository and I am still working on the photo model, so the release will be at the end of the month.

EDIT: workaround, manually download the zip file from https://github.com/nagadomi/nunif/releases/download/0.0.0/waifu2x_pretrained_models_20230202.zip and unzip to ./waifu2x/pretrained_models

Fixed by https://github.com/nagadomi/nunif/commit/f8f9151a1a40f5bca81dff4721f5d17aecfb7fd7 Also I have updated waifu2x/pretrained_models so re-download it.
