Evaluator

The evaluator classes for automatic evaluation.

Evaluator classes

The main entry point for using the evaluator:

evaluate.evaluator

< >

( task: str = None ) → Evaluator

Parameters

Returns

Evaluator

An evaluator suitable for the task.

Utility factory method to build an Evaluator. Evaluators encapsulate a task and a default metric name. They leverage pipeline functionality from transformers to simplify the evaluation of multiple combinations of models, datasets and metrics for a given task.

Examples:

>>> from evaluate import evaluator
>>> # Sentiment analysis evaluator
>>> evaluator("sentiment-analysis")

The base class for all evaluator classes:

class evaluate.Evaluator

< >

( task: str default_metric_name: str = None )

The Evaluator class is the class from which all evaluators inherit. Refer to this class for methods shared across different evaluators. Base class implementing evaluator operations.

check_required_columns

< >

( data: Union columns_names: Dict )

Parameters

  • data (str or Dataset) — Specifies the dataset we will run evaluation on.
  • columns_names (List[str]) — List of column names to check in the dataset. The keys are the arguments to the evaluate.EvaluationModule.compute() method, while the values are the column names to check.

Ensure the columns required for the evaluation are present in the dataset.

Example:

>>> from datasets import load_dataset
>>> from evaluate import evaluator
>>> data = load_dataset("rotten_tomatoes', split="train")
>>> evaluator.check_required_columns(data, {"input_column": "text", "label_column": "label"})

compute_metric

< >

( metric: EvaluationModule metric_inputs: Dict strategy: Literal = 'simple' confidence_level: float = 0.95 n_resamples: int = 9999 random_state: Optional = None )

Compute and return metrics.

get_dataset_split

< >

( data subset = None split = None ) → split

Parameters

  • data (str) — Name of dataset.
  • subset (str) — Name of config for datasets with multiple configurations (e.g. ‘glue/cola’).
  • split (str, defaults to None) — Split to use.

Returns

split

str containing which split to use

Infers which split to use if None is given.

Example:

>>> from evaluate import evaluator
>>> evaluator("text-classification").get_dataset_split(data="rotten_tomatoes")
WARNING:evaluate.evaluator.base:Dataset split not defined! Automatically evaluating with split: TEST
'test'

load_data

< >

( data: Union subset: str = None split: str = None ) → data (Dataset)

Parameters

  • data (Dataset or str, defaults to None) — Specifies the dataset we will run evaluation on. If it is of type str, we treat it as the dataset name, and load it. Otherwise we assume it represents a pre-loaded dataset.
  • subset (str, defaults to None) — Specifies dataset subset to be passed to name in load_dataset. To be used with datasets with several configurations (e.g. glue/sst2).
  • split (str, defaults to None) — User-defined dataset split by name (e.g. train, validation, test). Supports slice-split (test[:n]). If not defined and data is a str type, will automatically select the best one via choose_split().

Returns

data (Dataset)

Loaded dataset which will be used for evaluation.

Load dataset with given subset and split.

Example:

>>> from evaluate import evaluator
>>> evaluator("text-classification").load_data(data="rotten_tomatoes", split="train")
Dataset({
    features: ['text', 'label'],
    num_rows: 8530
})

predictions_processor

< >

( *args **kwargs )

A core method of the Evaluator class, which processes the pipeline outputs for compatibility with the metric.

prepare_data

< >

( data: Dataset input_column: str label_column: str *args **kwargs ) → dict

Parameters

  • data (Dataset) — Specifies the dataset we will run evaluation on.
  • input_column (str, defaults to "text") — The name of the column containing the text feature in the dataset specified by data.
  • second_input_column(str, optional) — The name of the column containing the second text feature if there is one. Otherwise, set to None.
  • label_column (str, defaults to "label") — The name of the column containing the labels in the dataset specified by data.

Returns

dict

metric inputs. list: pipeline inputs.

Prepare data.

Example:

>>> from evaluate import evaluator
>>> from datasets import load_dataset

>>> ds = load_dataset("rotten_tomatoes", split="train")
>>> evaluator("text-classification").prepare_data(ds, input_column="text", second_input_column=None, label_column="label")

prepare_metric

< >

( metric: Union )

Parameters

  • metric (str or EvaluationModule, defaults to None) — Specifies the metric we use in evaluator. If it is of type str, we treat it as the metric name, and load it. Otherwise we assume it represents a pre-loaded metric.

Prepare metric.

Example:

>>> from evaluate import evaluator
>>> evaluator("text-classification").prepare_metric("accuracy")

prepare_pipeline

< >

( model_or_pipeline: Union tokenizer: Union = None feature_extractor: Union = None device: int = None )

Parameters

  • model_or_pipeline (str or Pipeline or Callable or PreTrainedModel or TFPreTrainedModel, defaults to None) — If the argument in not specified, we initialize the default pipeline for the task. If the argument is of the type str or is a model instance, we use it to initialize a new Pipeline with the given model. Otherwise we assume the argument specifies a pre-initialized pipeline.
  • preprocessor (PreTrainedTokenizerBase or FeatureExtractionMixin, optional, defaults to None) — Argument can be used to overwrite a default preprocessor if model_or_pipeline represents a model for which we build a pipeline. If model_or_pipeline is None or a pre-initialized pipeline, we ignore this argument.

Prepare pipeline.

Example:

>>> from evaluate import evaluator
>>> evaluator("text-classification").prepare_pipeline(model_or_pipeline="distilbert-base-uncased")

Compute the metric for a given pipeline and dataset combination.

The dataset input and label columns are expected to be formatted as a list of words and a list of labels respectively, following conll2003 dataset. Datasets whose inputs are single strings, and labels are a list of offset are not supported.

Examples:

>>> from evaluate import evaluator
>>> from datasets import load_dataset
>>> task_evaluator = evaluator("token-classification")
>>> data = load_dataset("conll2003", split="validation[:2]")
>>> results = task_evaluator.compute(
>>>     model_or_pipeline="elastic/distilbert-base-uncased-finetuned-conll03-english",
>>>     data=data,
>>>     metric="seqeval",
>>> )

For example, the following dataset format is accepted by the evaluator:

dataset = Dataset.from_dict(
    mapping={
        "tokens": [["New", "York", "is", "a", "city", "and", "Felix", "a", "person", "."]],
        "ner_tags": [[1, 2, 0, 0, 0, 0, 3, 0, 0, 0]],
    },
    features=Features({
        "tokens": Sequence(feature=Value(dtype="string")),
        "ner_tags": Sequence(feature=ClassLabel(names=["O", "B-LOC", "I-LOC", "B-PER", "I-PER"])),
        }),
)

For example, the following dataset format is not accepted by the evaluator:

dataset = Dataset.from_dict(
    mapping={
        "tokens": [["New York is a city and Felix a person."]],
        "starts": [[0, 23]],
        "ends": [[7, 27]],
        "ner_tags": [["LOC", "PER"]],
    },
    features=Features({
        "tokens": Value(dtype="string"),
        "starts": Sequence(feature=Value(dtype="int32")),
        "ends": Sequence(feature=Value(dtype="int32")),

Parameters

  • model_or_pipeline (str or Pipeline or Callable or PreTrainedModel or TFPreTrainedModel, defaults to None) — If the argument in not specified, we initialize the default pipeline for the task (in this case text-classification or its alias - sentiment-analysis). If the argument is of the type str or is a model instance, we use it to initialize a new Pipeline with the given model. Otherwise we assume the argument specifies a pre-initialized pipeline.
  • data (str or Dataset, defaults to None) — Specifies the dataset we will run evaluation on. If it is of type str, we treat it as the dataset name, and load it. Otherwise we assume it represents a pre-loaded dataset.
  • subset (str, defaults to None) — Defines which dataset subset to load. If None is passed the default subset is loaded.
  • split (str, defaults to None) — Defines which dataset split to load. If None is passed, infers based on the choose_split function.
  • metric (str or EvaluationModule, defaults to None) — Specifies the metric we use in evaluator. If it is of type str, we treat it as the metric name, and load it. Otherwise we assume it represents a pre-loaded metric.
  • tokenizer (str or PreTrainedTokenizer, optional, defaults to None) — Argument can be used to overwrite a default tokenizer if model_or_pipeline represents a model for which we build a pipeline. If model_or_pipeline is None or a pre-initialized pipeline, we ignore this argument.
  • strategy (Literal["simple", "bootstrap"], defaults to “simple”) — specifies the evaluation strategy. Possible values are:
  • confidence_level (float, defaults to 0.95) — The confidence_level value passed to bootstrap if "bootstrap" strategy is chosen.
  • n_resamples (int, defaults to 9999) — The n_resamples value passed to bootstrap if "bootstrap" strategy is chosen.
  • device (int, defaults to None) — Device ordinal for CPU/GPU support of the pipeline. Setting this to -1 will leverage CPU, a positive integer will run the model on the associated CUDA device ID. If None is provided it will be inferred and CUDA:0 used if available, CPU otherwise.
  • random_state (int, optional, defaults to None) — The random_state value passed to bootstrap if "bootstrap" strategy is chosen. Useful for debugging.
  • input_column (str, defaults to "text") — the name of the column containing the input text in the dataset specified by data.
  • label_column (str, defaults to "label") — the name of the column containing the labels in the dataset specified by data.
  • generation_kwargs (Dict, optional, defaults to None) — The generation kwargs are passed to the pipeline and set the text generation strategy.

Compute the metric for a given pipeline and dataset combination.

Examples:

>>> from evaluate import evaluator
>>> from datasets import load_dataset
>>> task_evaluator = evaluator("translation")
>>> data = load_dataset("wmt19", "fr-de", split="validation[:40]")
>>> data = data.map(lambda x: {"text": x["translation"]["de"], "label": x["translation"]["fr"]})

Examples:

Remember that, in order to process audio files, you need ffmpeg installed (https://ffmpeg.org/download.html)

>>> from evaluate import evaluator
>>> from datasets import load_dataset

>>> task_evaluator = evaluator("audio-classification")
>>> data = load_dataset("superb", 'ks', split="test[:40]")
>>> results = task_evaluator.compute(
>>>     model_or_pipeline=""superb/wav2vec2-base-superb-ks"",
>>>     data=data,
>>>     label_column="label",
>>>     input_column="file",
>>>     metric="accuracy",
>>>     label_mapping={0: "yes", 1: "no", 2: "up", 3: "down"}
>>> )

The evaluator supports raw audio data as well, in the form of a numpy array. However, be aware that calling the audio column automatically decodes and resamples the audio files, which can be slow for large datasets.

>>> from evaluate import evaluator
>>> from datasets import load_dataset

>>> task_evaluator = evaluator("audio-classification")
>>> data = load_dataset("superb", 'ks', split="test[:40]")
>>> data = data.map(lambda example: {"audio": example["audio"]["array"]})
>>> results = task_evaluator.compute(
>>>     model_or_pipeline=""superb/wav2vec2-base-superb-ks"",
>>>     data=data,
>>>     label_column="label",
>>>     input_column="audio",
>>>     metric="accuracy",
>>>     label_mapping={0: "yes", 1: "no", 2: "up", 3: "down"}
>>> )
