release_pypi_package.sh

#!/bin/bash
#
# A script for creating and releasing the TensorFlow GAN PyPi package.
#
# Usage:
#  ./release_pypi_package.sh {test|live}
#
# Order of operations of this script:
# 1) Build and test the whls (one for each desired version of Python).
# 2) Publish the whl (in test or live mode). Contact a TF-GAN team member if you
#    think you have a good reason to be building PyPi packages.
#
# To test that the package was uploaded, you can run the following:
#  $ pip install --index-url https://test.pypi.org/simple/ tensorflow-gan --upgrade
#  $ pip install tensorflow-gan --upgrade
#
# The resulting packages will be visible here:
#  $ https://pypi.org/project/tensorflow-gan/
#  $ https://test.pypi.org/project/tensorflow-gan/

set -e  # fail and exit on any command erroring

# Bring in useful functions.
