Spot check! Make sure you have the following files in your working directory:

├── docker
│   ├── build.sh
│   ├── clean.sh
│   └── Dockerfile
├── README.md
├── run.sh
└── src
|   ├── generator.py
|   ├── discriminator.py
|   ├── gan.py
|   ├── train.py

Make sure you have the generator, discriminator, and GAN networks all built—otherwise, nothing in the training script will work!
