- Python 2.7, numpy
- Tensorflow 0.12
- OpenCV

1. make a folder called "results"
2. make a folder called "imgs"
3. Fill the "imgs" folder with your own .jpg images, or run "download_images.py" to download from Safebooru.
4. Run "python main.py train". I trained for ~20 epochs, taking about 16 hours on one GPU.
5. To sample, run "python main.py sample"
6. To start the server, run "python server.py". It will host on port 8000.

Folder structure should go:

main.py
server.py
checkpoint/
    tr/
        checkpoint
        model-1101500.index
        model-1101500.data-00000-of-00001
        model-1101500.meta

Code based off this pix2pix implementation.
