Merge pull request #229 from claranet/fix/replace_deprecated_set_output · claranet/tfwrapper@4c3207f

Unexpected input(s) 'python_version', valid inputs are ['python-version', 'python-version-file', 'cache', 'architecture', 'check-latest', 'token', 'cache-dependency-path', 'update-environment', 'allow-prereleases']

The `python-version` input is not set. The version of Python currently in `PATH` will be used.
