Related Projects

CycleGAN: Unpaired Image-to-Image Translation using Cycle-Consistent Adversarial Networks. Software that can generate photos from paintings, turn horses into zebras, perform style transfer, and more.

Requirements and versions:

• Python 3.5

• Git

• Tensorflow 1.12.0

Important: When committing, remember to be in the virtual environment, for hooks to work.

NOTE: All code in Jupyter Notebooks is purely experimental. Use at your own risk.

Setup

Make sure there is no venv/ directory in your repository. If there is, remove it. Run the following commands:

./setup/create_venv.sh
source venv/bin/activate

Important: For all commands here, we assume you are sourced into the virtual environment: source venv/bin/activate

Running the experiments

Image conversion

Put all data into the directories in data_in/. Supported are: 1_BCDR/, 2_INbreast/, 3_zrh/, cbis.

1. ./local/convert_images_all.sh

2. ./local/merge_images_all.sh

3. ./local/split_images_all.sh

4. ./local/treval_split.sh

GAN training

1. ./local/run.sh. Wait 24 hours.

2. ./local/infer.sh. Make sure to enter the correct checkpoint number here and below.

3. ./local/to_png.sh. Make sure to change the paths in notebooks/inference_tfrecord_to_png.py.

Jupyter notebooks

NOTE: All code in Jupyter Notebooks is purely experimental. Use at your own risk.

Save notebooks in the notebooks/ directory. These can also be worked on locally using Jupyter. In the project root directory, you can run either:

• jupyter notebook,

• or jupyter lab.

Add the following cell to your notebook, ideally in a "section":

# noqa
import os
wd = %pwd
print('Current directory:', wd)
if wd.endswith('notebooks'):
    %cd ..

Docker / Custom runner

After you have converted images and built a Docker image using: make build-cpu or make build-gpu (or pulling one from the remote Docker hub), you can use the Docker wrapper:

./run_docker.sh password jupyter  # Jupyter Notebooks
./run_docker.sh password lab  # Jupyter Lab
./run_docker.sh password model  # Train model
./run_docker.sh password modelboard  # Train model + run TensorBoard

Directory structure

• cluster/ — scripts for running the training/evaluation on the cluster

• data_in/ — input data and associated scripts/configs

• data_out/ — output data and logs + associated scripts/configs

• docker/ — setup and configs for running stuff inside and outside of Docker

• local/ — scripts for running the training/evaluation locally

• models/ — scripts defining the models + hyperparameters

• notebooks/ — data exploration and other rapid development notebooks

  • Models from here should eventually be promoted into models/

• resources/ — Python utilities

• setup/ — environment setup and verification scripts in Python/Bash

• venv/ — the (local) Python virtual environment

Formatting

Run: ./setup/clean.sh. A Git hook will tell you if any files are misformatted before committing.
