| r""" | |
| Instantiate one of the processor classes of the library from a pretrained model vocabulary. | |
| The processor class to instantiate is selected based on the `model_type` property of the config object (either | |
| passed as an argument or loaded from `pretrained_model_name_or_path` if possible): | |
| List options | |
| Params: | |
| pretrained_model_name_or_path (`str` or `os.PathLike`): | |
| This can be either: | |
| - a string, the *model id* of a pretrained feature_extractor hosted inside a model repo on | |
| huggingface.co. | |
| - a path to a *directory* containing a processor files saved using the `save_pretrained()` method, | |
| e.g., `./my_model_directory/`. | |
| cache_dir (`str` or `os.PathLike`, *optional*): | |
| Path to a directory in which a downloaded pretrained model feature extractor should be cached if the | |
| standard cache should not be used. | |
| force_download (`bool`, *optional*, defaults to `False`): | |
| Whether or not to force to (re-)download the feature extractor files and override the cached versions | |
| if they exist. | |
| resume_download: | |
| Deprecated and ignored. All downloads are now resumed by default when possible. | |
| Will be removed in v5 of Transformers. | |
| 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. | |
| token (`str` or *bool*, *optional*): | |
| The token to use as HTTP bearer authorization for remote files. If `True`, will use the token generated | |
| when running `hf auth login` (stored in `~/.huggingface`). | |
| 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 feature extractor object. If `True`, then this | |
| functions returns a `Tuple(feature_extractor, unused_kwargs)` where *unused_kwargs* is a dictionary | |
| consisting of the key/value pairs whose keys are not feature extractor attributes: i.e., the part of | |
| `kwargs` which has not been used to update `feature_extractor` 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 (`dict[str, Any]`, *optional*): | |
| The values in kwargs of any keys which are feature extractor attributes will be used to override the | |
| loaded values. Behavior concerning key/value pairs whose keys are *not* feature extractor attributes is | |
| controlled by the `return_unused_kwargs` keyword parameter. | |
| <Tip> | |
| Passing `token=True` is required when you want to use a private model. | |
| </Tip> | |
| Examples: | |
| ```python | |
| >>> from transformers import AutoProcessor | |
| >>> # Download processor from huggingface.co and cache. | |
| >>> processor = AutoProcessor.from_pretrained("facebook/wav2vec2-base-960h") | |
| >>> # If processor files are in a directory (e.g. processor was saved using *save_pretrained('./test/saved_model/')*) | |
| >>> # processor = AutoProcessor.from_pretrained("./test/saved_model/") | |
