setup-python: Version 3 was not found in the local cache

[wvidana]

Using Codebuild for Github Action Runners (self-hosted in Codebuild). The setup-python action tries to search for a local Python, but it couldn't find any Python 3.

I'm using the aws/codebuild/standard:7.0 image. Is there any way to get an Ubuntu image with a python version pre-installed? Because of how codebuild works with github, I can't really specify a buildspec, it gets overriden by github
