cannot import name 'Metric' from partially initialized module 'ignite.metrics' #3319
Description
from ignite.metrics import Metric
ImportError: cannot import name 'Metric' from partially initialized module 'ignite.metrics' (most likely due to a circular import)
/ignite/metrics/init.py)
I solved that by
def create_supervised_evaluator(
model: torch.nn.Module,
# metrics: Optional[Dict[str, Metric]] = None, #############this is the problem，i modify i by delete Optional[Dict[str, Metric]].
metrics = None,
device: Optional[Union[str, torch.device]] = None,
non_blocking: bool = False,
prepare_batch: Callable = _prepare_batch,
model_transform: Callable[[Any], Any] = lambda output: output,
output_transform: Callable[[Any, Any, Any], Any] = lambda x, y, y_pred: (y_pred, y),
amp_mode: Optional[str] = None,
model_fn: Callable[[torch.nn.Module, Any], Any] = lambda model, x: model(x),
) -> Engine:
Does have other ways to solve that？I dont want to modify source file.
