CPython version 2.7.x is not supported by actions/setup-python. This probably means you are using a deprecated version. If this is not the case, you may suppress the warning setting input "allow-build" to either "info" or "allow".

The support for python 2.7 will be removed on June 19. Related issue: https://github.com/actions/setup-python/issues/672
