CPython version >=2.7.0 <2.8.0-0 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".

Specific version 2.7.18 is no longer officially supported. This action will not break support intentionally but no effort will be spent in supporting it.

The support for python 2.7 was removed on June 19, 2023. Related issue: https://github.com/actions/setup-python/issues/672
