class matlantis_features.features.elasticity.elastic_properties.PostElasticPropertiesFeature#

Bases: FeatureBase

The matlantis-feature for calculating elastic properties.

Including bulk modulus, shear modulus, Young’s modulus, poisson ratio etc.

Methods

__init__()

Initialize an instance.

__call__(elastic_tensor)

Call function.

attach_ctx([ctx])

Attach the feature to matlantis_features.utils.Context.

check_estimator_fn(estimator_fn)

Checks if the given estimator function is None and output a warning if so.

cost_estimate([atoms])

Estimate the cost of the feature.

from_dict(res)

Construct a FeatureBase object from serialized dict.

get_savedir_from_ctx()

Get the temporary save directory from the context.

init_scope()

Context manager that enable to set attribution of the feature.

repeat(n_repeat)

Set the maximum number of times that allowed to run the __call__ function.

to_dict()

Dictionary representation of the FeatureBase.
__init__() → None#

Initialize an instance.

__call__(elastic_tensor: ElasticTensor) → ElasticProperties#

Call function.

Parameters

elastic_tensor (ElasticTensor) – Elastic tensor object calculated by ElasticTensorFeature.

Returns

Resulting elastic properties object.

Return type

ElasticProperties

attach_ctx(ctx: Optional[Context] = None) → None#

Attach the feature to matlantis_features.utils.Context.

Parameters

ctx (Context or None, optional) – The matlantis_features.utils.Context object. Defaults to None.

check_estimator_fn(estimator_fn: Optional[Callable[[], Estimator]]) → None#

Checks if the given estimator function is None and output a warning if so.

Parameters

estimator_fn (EstimatorFnType or None, optional) – A factory method to create a custom estimator.
Please refer Customizing estimator used in matlantis-features for detail. Defaults to None.

cost_estimate(atoms: Optional[Union[Atoms, MatlantisAtoms]] = None) → FeatureCost#

Estimate the cost of the feature.

Parameters

atoms (ASEAtoms or MatlantisAtoms or None, optional) – The input atoms. Defaults to None.

Returns

The cost of the feature.

Return type

FeatureCost

classmethod from_dict(res: Dict[str, Any]) → FeatureBase#

Construct a FeatureBase object from serialized dict.

Parameters

res (dict[str, Any]) – A dict containing a serialized FeatureBase from to_dict().

Returns

The deserialized object from provided dict.

Return type

FeatureBase

get_savedir_from_ctx() → Path#

Get the temporary save directory from the context.

Returns

The temporary save directory .

Return type

pathlib.Path

init_scope() → Iterator[None]#

Context manager that enable to set attribution of the feature.

Returns

Init_scope context manager.

Return type

Iterator[None]

repeat(n_repeat: int) → Self#

Set the maximum number of times that allowed to run the __call__ function.

Parameters

n_repeat (int) – The maximum number of repeats.

Returns

The feature.

Return type

Self

to_dict() → Dict[str, Any]#

Dictionary representation of the FeatureBase.

Returns

A dict containing a serialized FeatureBase.

Return type

dict[str, Any]
