Steps

Step 1. Install Python on Windows

Version 3.8 of Windows x86-64 executable installer seems better: https://www.python.org/downloads/windows/

Step 2. Install richzhang/colorization

Clone the repository

git clone https://github.com/richzhang/colorization.git

CUDA

Others

Please note that I chose scikit-image instead of skimage.

pip install wheel scikit-image matplotlib argparse
pip install ipython

Step 3. Run

cd colorization
python demo_release.py -i imgs/ansel_adams3.jpg
