-Download the data and place it in the directory specified by `data_dir` flag:
-
-    mkdir -p /tmp/emnlp2017

-Create and activate a virtual environment if needed:
-
-    virtualenv scratchgan-venv
-    source scratchgan-venv/bin/activate
-
-
-Note: the code uses python 2. This might mean that to create the virtual env
-you have to pass a path to the python binary to be used, as follows:
-`virtualenv -p /usr/bin/python2.7 scratchgan-venv`.
-
-Install requirements:
-
-    pip install -r scratchgan/requirements.txt
-
-Run training and evaluation jobs:
-
-    python2 -m scratchgan.experiment --mode="train" &
-    python2 -m scratchgan.experiment --mode="evaluate_pair" &
-
-The evaluation code is designed to run in parallel with the training.
-
-The training code saves checkpoints periodically, the evaluation code
-looks for new checkpoints and evaluate them.
