from dataclasses import dataclass, field
from typing import List, Any
from omegaconf import OmegaConf
@dataclass
class Example:
num: int
@dataclass
class TestConfig(Example):
common: Example = field(default_factory=Example)
for k, field_info in TestConfig.__dataclass_fields__.items():
default_value = field_info.default
default_factory = field_info.default_factory
print(
f"Field: {k}, Default Value: {default_value}, Default Factory: {default_factory}"
)
mis = OmegaConf.structured(default_factory)
Expected behavior
Maybe add a type judgement for better compatibility.
Describe the bug
In Python version >= 3.11, dataclasses prohibits setting the default value to mutable objects
so this is often the case :
common: Example = field(default_factory=Example)
Here, if no assignment is given, the object becomes a _MISSING_TYPE.
When using this type in
OmegaConf.structured
, an error will occur.Just like this https://github.com/facebookresearch/fairseq/pull/5359#issuecomment-1779634288
To Reproduce
Run the code below will get this error
Expected behavior
Maybe add a type judgement for better compatibility.
