The following works for users on MacOS; I have not tested it on other platforms.
I've converted the PyQt4 code to PyQt5 in order to make this app easily runnable with Python 3.
Please follow this guide (https://sourabhbajaj.com/blog/2017/02/07/gui-applications-docker-mac/) to install & configure XQuartz (and Docker if you haven't already!)
Assuming you've git-cloned this repository and are currently in the ideepcolor/ repository:
cd docker
bash models/pytorch/fetch_model.sh # Fetches the PyTorch model
docker build -t colorize .
docker image ls
You should see a list of Docker images, one of them named colorize.
Then:
xhost + 127.0.0.1
docker run -e DISPLAY=host.docker.internal:0 colorize
in order to run the app!
