        Args:
            model:
                The full Hugging Face Hub path(s) to the pretrained transformer model.
                The specific model version to use can be added after the suffix '@':
                "model@v1.0.0". It can be a branch name, a tag name, or a commit id,
                and defaults to the latest version if not specified.
            task:
                The tasks benchmark the model(s) on. Mutually exclusive with `dataset`.
                If both `task` and `dataset` are None then all datasets will be
                benchmarked. Defaults to None.
            dataset:
                The datasets to benchmark on. Mutually exclusive with `task`. If both
                `task` and `dataset` are None then all datasets will be benchmarked.
                Defaults to None.
            progress_bar:
                Whether progress bars should be shown. Defaults to the value specified

                Whether to save the benchmark results to
                'euroeval_benchmark_results.jsonl'. Defaults to the value specified
                when initialising the benchmarker.
            language:
                The language codes of the languages to include, both for models and
                datasets. Here 'no' means both Bokmål (nb) and Nynorsk (nn). Set this to
                'all' if all languages should be considered. Defaults to the value
                specified when initialising the benchmarker.
            model_language:
                The language codes of the languages to include for models. If specified
                then this overrides the `language` parameter for model languages.
                Defaults to the value specified when initialising the benchmarker.
            dataset_language:
                The language codes of the languages to include for datasets. If
                specified then this overrides the `language` parameter for dataset
                languages. Defaults to the value specified when initialising the
                benchmarker.
            device:
                The device to use for benchmarking. Defaults to the value specified when
                initialising the benchmarker.
            batch_size:
                The batch size to use. Defaults to the value specified when initialising
                the benchmarker.
            raise_errors:
                Whether to raise errors instead of skipping the model evaluation.
            cache_dir:
                Directory to store cached models. Defaults to the value specified when
                initialising the benchmarker.
            api_key:
                The API key to use for a given inference server. Defaults to the value
                specified when initialising the benchmarker.
            force:
                Whether to force evaluations of models, even if they have been
                benchmarked already. Defaults to the value specified when initialising
                the benchmarker.
            verbose:
                Whether to output additional output. Defaults to the value specified
                when initialising the benchmarker.
            trust_remote_code:
                Whether to trust remote code when loading models. Defaults to the value
                specified when initialising the benchmarker.
            use_flash_attention:
                Whether to use Flash Attention. Defaults to the value specified when
                initialising the benchmarker.
            clear_model_cache:
                Whether to clear the model cache after benchmarking each model. Defaults
                to the value specified when initialising the benchmarker.
            evaluate_test_split:
                Whether to evaluate the test split of the datasets. Defaults to the
                value specified when initialising the benchmarker.
            few_shot:
                Whether to only evaluate the model using few-shot evaluation. Only
                relevant if the model is generative. Defaults to the value specified
                when initialising the benchmarker.
            num_iterations:
                The number of times each model should be evaluated. This is only meant
                to be used for power users, and scores will not be allowed on the
                leaderboards if this is changed. Defaults to the value specified when
                initialising the benchmarker.
            only_allow_safetensors:
                Whether to only allow models that use the safetensors format. Defaults
                to the value specified when initialising the benchmarker.
