        Instantiate one of the configuration classes of the library from a pretrained model configuration.

        The configuration class to instantiate is selected based on the `model_type` property of the config object that
        is loaded, or when it's missing, by falling back to using pattern matching on `pretrained_model_name_or_path`:

        List options

        Args:
            pretrained_model_name_or_path (`str` or `os.PathLike`):
                Can be either:

                    - A string, the *model id* of a pretrained model configuration 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 configuration file saved using the
                      [`~PretrainedConfig.save_pretrained`] method, or the [`~PreTrainedModel.save_pretrained`] method,
                      e.g., `./my_model_directory/`.
                    - A path or url to a saved configuration JSON *file*, e.g.,
                      `./my_model_directory/configuration.json`.
            cache_dir (`str` or `os.PathLike`, *optional*):
                Path to a directory in which a downloaded pretrained model configuration should be cached if the
                standard cache should not be used.
            force_download (`bool`, *optional*, defaults to `False`):
                Whether or not to force the (re-)download the model weights and configuration files and override the
                cached versions if they exist.
            resume_download (`bool`, *optional*, defaults to `False`):
                Whether or not to delete incompletely received files. Will attempt to resume the download if such a
                file exists.
            proxies (`Dict[str, str]`, *optional*):
                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.
            revision (`str`, *optional*, defaults to `"main"`):
                The specific model version to use. It can be a branch name, a tag name, or a commit id, since we use a
                git-based system for storing models and other artifacts on huggingface.co, so `revision` can be any
                identifier allowed by git.
            return_unused_kwargs (`bool`, *optional*, defaults to `False`):
                If `False`, then this function returns just the final configuration object.

                If `True`, then this functions returns a `Tuple(config, unused_kwargs)` where *unused_kwargs* is a
                dictionary consisting of the key/value pairs whose keys are not configuration attributes: i.e., the
                part of `kwargs` which has not been used to update `config` and is otherwise ignored.
            trust_remote_code (`bool`, *optional*, defaults to `False`):
                Whether or not to allow for custom models defined on the Hub in their own modeling files. This option
                should only be set to `True` for repositories you trust and in which you have read the code, as it will
                execute code present on the Hub on your local machine.
            kwargs(additional keyword arguments, *optional*):
                The values in kwargs of any keys which are configuration attributes will be used to override the loaded
                values. Behavior concerning key/value pairs whose keys are *not* configuration attributes is controlled
                by the `return_unused_kwargs` keyword parameter.

        Examples:

        ```python
        >>> from transformers import AutoConfig

        >>> # Download configuration from huggingface.co and cache.
        >>> config = AutoConfig.from_pretrained("bert-base-uncased")

        >>> # Download configuration from huggingface.co (user-uploaded) and cache.
        >>> config = AutoConfig.from_pretrained("dbmdz/bert-base-german-cased")

        >>> # If configuration file is in a directory (e.g., was saved using *save_pretrained('./test/saved_model/')*).
        >>> config = AutoConfig.from_pretrained("./test/bert_saved_model/")

        >>> # Load a specific configuration file.
        >>> config = AutoConfig.from_pretrained("./test/bert_saved_model/my_configuration.json")

        >>> # Change some config attributes when loading a pretrained config.
        >>> config = AutoConfig.from_pretrained("bert-base-uncased", output_attentions=True, foo=False)
