# Set some environment variables. PYTHONUNBUFFERED keeps Python from
# buffering our standard output stream, which means that logs can be
# delivered to the user quickly. PYTHONDONTWRITEBYTECODE keeps Python
# from writing the .pyc files which are unnecessary in this case. We also
# update PATH so that the train and serve programs are found when the
# container is invoked.
