        Instantiate a [`ModelCard`] from a pre-trained model model card.

        Parameters:
            pretrained_model_name_or_path: either:

                - a string, the *model id* of a pretrained model card hosted inside a model repo on huggingface.co.
                  Valid model ids can be located at the root-level, like `bert-base-uncased`, or namespaced under a
                  user or organization name, like `dbmdz/bert-base-german-cased`.
                - a path to a *directory* containing a model card file saved using the [`~ModelCard.save_pretrained`]
                  method, e.g.: `./my_model_directory/`.
                - a path or url to a saved model card JSON *file*, e.g.: `./my_model_directory/modelcard.json`.

            cache_dir: (*optional*) string:
                Path to a directory in which a downloaded pre-trained model card should be cached if the standard cache
                should not be used.

            kwargs: (*optional*) dict: key/value pairs with which to update the ModelCard object after loading.

                - The values in kwargs of any keys which are model card attributes will be used to override the loaded
                  values.
                - Behavior concerning key/value pairs whose keys are *not* model card attributes is controlled by the
                  *return_unused_kwargs* keyword parameter.

            proxies: (*optional*) dict, default None:
                A dictionary of proxy servers to use by protocol or endpoint, e.g.: {'http': 'foo.bar:3128',
                'http://hostname': 'foo.bar:4012'}. The proxies are used on each request.

            return_unused_kwargs: (*optional*) bool:

                - If False, then this function returns just the final model card object.
                - If True, then this functions returns a tuple *(model card, unused_kwargs)* where *unused_kwargs* is a
                  dictionary consisting of the key/value pairs whose keys are not model card attributes: ie the part of
                  kwargs which has not been used to update *ModelCard* and is otherwise ignored.

        Examples:

        ```python
        # Download model card from huggingface.co and cache.
        modelcard = ModelCard.from_pretrained("bert-base-uncased")
        # Model card was saved using *save_pretrained('./test/saved_model/')*
