classmethod model_construct(_fields_set=None, **values)

Creates a new instance of the Model class with validated data.

Creates a new model setting __dict__ and __pydantic_fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed.

!!! note

model_construct() generally respects the model_config.extra setting on the provided model. That is, if model_config.extra == ‘allow’, then all extra passed values are added to the model instance’s __dict__ and __pydantic_extra__ fields. If model_config.extra == ‘ignore’ (the default), then all extra passed values are ignored. Because no validation is performed with a call to model_construct(), having model_config.extra == ‘forbid’ does not result in an error if extra values are passed, but they will be ignored.

Parameters:

  • _fields_set (set[str] | None) – The set of field names accepted for the Model instance.

  • values (Any) – Trusted or pre-validated data dictionary.

Returns:

A new instance of the Model class with validated data.

class nucleus.validate.data_transfer_objects.eval_function.EvaluationCriterion(**data)

An Evaluation Criterion is defined as an evaluation function, threshold, and comparator. It describes how to apply an evaluation function

Notes

To define the evaluation criteria for a scenario test we’ve created some syntactic sugar to make it look closer to an actual function call, and we also hide away implementation details related to our data model that simply are not clear, UX-wise.

Instead of defining criteria like this:

from nucleus.validate.data_transfer_objects.eval_function import (
    EvaluationCriterion,
    ThresholdComparison,
)

criteria = [
    EvaluationCriterion(
        eval_function_id="ef_c6m1khygqk400918ays0",  # bbox_recall
        threshold_comparison=ThresholdComparison.GREATER_THAN,
        threshold=0.5,
    ),
]

we define it like this:

bbox_recall = client.validate.eval_functions.bbox_recall
criteria = [
    bbox_recall() > 0.5
]

The chosen method allows us to document the available evaluation functions in an IDE friendly fashion and hides away details like internal IDs (“ef_….”).

The actual EvaluationCriterion is created by overloading the comparison operators for the base class of an evaluation function. Instead of the comparison returning a bool, we’ve made it create an EvaluationCriterion with the correct signature to send over the wire to our API.

Parameters:

  • eval_function_id (str) – ID of evaluation function

  • threshold_comparison (ThresholdComparison) – comparator for evaluation. i.e. threshold=0.5 and threshold_comparator > implies that a test only passes if score > 0.5.

  • threshold (float) – numerical threshold that together with threshold comparison, defines success criteria for test evaluation.

  • eval_func_arguments – Arguments to pass to the eval function constructor

  • data (Any)

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

classmethod model_construct(_fields_set=None, **values)

Creates a new instance of the Model class with validated data.

Creates a new model setting __dict__ and __pydantic_fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed.

!!! note

model_construct() generally respects the model_config.extra setting on the provided model. That is, if model_config.extra == ‘allow’, then all extra passed values are added to the model instance’s __dict__ and __pydantic_extra__ fields. If model_config.extra == ‘ignore’ (the default), then all extra passed values are ignored. Because no validation is performed with a call to model_construct(), having model_config.extra == ‘forbid’ does not result in an error if extra values are passed, but they will be ignored.

Parameters:

  • _fields_set (set[str] | None) – The set of field names accepted for the Model instance.

  • values (Any) – Trusted or pre-validated data dictionary.

Returns:

A new instance of the Model class with validated data.

Return type:

Parameters:

  • deep (bool) – Set to True to make a deep copy of the model.

Returns:

New model instance.

Return type:

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

Parameters:

  • mode (Literal[json, python] | str) – The mode in which to_python should run. If mode is ‘json’, the output will only contain JSON serializable types. If mode is ‘python’, the output may contain non-JSON-serializable Python objects.
