# AutoConfig

### AutoConfig

#### class transformers.AutoConfig

[\<source>](https://github.com/huggingface/transformers/blob/v4.34.1/src/transformers/models/auto/configuration_auto.py#L910)

( )

This is a generic configuration class that will be instantiated as one of the configuration classes of the library when created with the [from\_pretrained()](https://huggingface.co/docs/transformers/v4.34.1/en/model_doc/auto#transformers.AutoConfig.from_pretrained) class method.

This class cannot be instantiated directly using `__init__()` (throws an error).

**from\_pretrained**

[\<source>](https://github.com/huggingface/transformers/blob/v4.34.1/src/transformers/models/auto/configuration_auto.py#L933)

( pretrained\_model\_name\_or\_path\*\*kwargs )

Parameters

* **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 [save\_pretrained()](https://huggingface.co/docs/transformers/v4.34.1/en/main_classes/configuration#transformers.PretrainedConfig.save_pretrained) method, or the [save\_pretrained()](https://huggingface.co/docs/transformers/v4.34.1/en/main_classes/model#transformers.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.

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`:
