# This action runs through ImageIO's continous integration pipeline. It
# performs the following checks:
# 
# - Linting/Style (Black)
# - Invokes the unit tests in no-internet mode on python 3.8
# - runs unit test on cypthon in matrix mode (python 3.6, 3.7, 3.8, 3.9) x (3 major OS)
# - runs unit tests on pypy in matrix mode (pypy 3.6, 3.7) x (3 major OS)
