+ Can be either:
+
+ - A string, the *model id* (for example `google/ddpm-celebahq-256`) of a pretrained model hosted on
+ the Hub.
+ - A path to a *directory* (for example `./my_model_directory`) containing the model weights saved
+ with [`ModelMixin.save_pretrained`].
+ - A [torch state
+ dict](https://pytorch.org/tutorials/beginner/saving_loading_models.html#what-is-a-state-dict).
+
+ cache_dir (`Union[str, os.PathLike]`, *optional*):
+ Path to a directory where a downloaded pretrained model configuration is cached if the standard cache
+ is not used.
+ force_download (`bool`, *optional*, defaults to `False`):
+ Whether or not to force the (re-)download of the model weights and configuration files, overriding the
+ cached versions if they exist.
+
+ proxies (`Dict[str, str]`, *optional*):
+ A dictionary of proxy servers to use by protocol or endpoint, for example, `{'http': 'foo.bar:3128',
+ 'http://hostname': 'foo.bar:4012'}`. The proxies are used on each request.
+ local_files_only (`bool`, *optional*, defaults to `False`):
+ Whether to only load local model weights and configuration files or not. If set to `True`, the model
+ won't be downloaded from the Hub.
+ token (`str` or *bool*, *optional*):
+ The token to use as HTTP bearer authorization for remote files. If `True`, the token generated from
+ `diffusers-cli login` (stored in `~/.huggingface`) is used.
+ revision (`str`, *optional*, defaults to `"main"`):
+ The specific model version to use. It can be a branch name, a tag name, a commit id, or any identifier
+ allowed by Git.
+ subfolder (`str`, *optional*, defaults to `""`):
+ The subfolder location of a model file within a larger model repository on the Hub or locally.
