This is the proposed way to use the configuration file:

from gromo.config.loader import load_config
from gromo.utils.utils import set_from_conf

self._config_data, _ = load_config()
if `local_variable` is None:
    `local_variable` = set_from_conf(self, "variable_name_in_config", default_value, setter=False)

The local variable should have a default value of None in the class, the default value can only be precised in the set_from_conf function. If you want the functionality of self.variable_name_in_config = value do setter=True
