Using Enums with Hydra's instantiate?

[stwerner97]

Hi, how can I instantiate an enum with Hydra's instantiate method?

The code below throws an error, because the Enum does not take an argument DNN upon creation.

from enum import Enum

from omegaconf import OmegaConf
from hydra.utils import instantiate

class MyEnum(Enum):
    DNN = "DeepNeuralNetwork"

cfg = OmegaConf.create(
    {"_target_": "script.MyEnum", "DNN": "DeepNeuralNetwork"}
)

myenum = instantiate(cfg)

Indeed it shouldn't be a keyword argument, instead use:

cfg = OmegaConf.create(
    {"_target_": "script.MyEnum", "_args_": ["DeepNeuralNetwork"]}
)

Thanks!
