Loaders
There are many weights to train adapter neural networks for diffusion models, such as
Textual Inversion
LoRA
Hypernetworks
Such adapter neural networks often only consist of a fraction of the number of weights compared
to the pretrained model and as such are very portable. The Diffusers library offers an easy-to-use
API to load such adapter neural networks via the loaders.py module.
Note: This module is still highly experimental and prone to future changes.

Parameters
pretrained_model_name_or_path_or_dict (str or os.PathLike or dict) β€”
Can be either:
A string, the model id of a pretrained model hosted inside a model repo on huggingface.co.
Valid model ids should have an organization name, like google/ddpm-celebahq-256.
A path to a directory containing model weights saved using ~ModelMixin.save_config, e.g.,
./my_model_directory/.
A torch state
dict.
cache_dir (Union[str, os.PathLike], optional) β€”
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) β€”
Whether or not to force the (re-)download of the model weights and configuration files, overriding the
cached versions if they exist.
resume_download (bool, optional, defaults to False) β€”
Whether or not to delete incompletely received files. Will attempt to resume the download if such a
file exists.
proxies (Dict[str, str], optional) β€”
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.
local_files_only(bool, optional, defaults to False) β€”
Whether or not to only look at local files (i.e., do not try to download the model).
use_auth_token (str or bool, optional) β€”
The token to use as HTTP bearer authorization for remote files. If True, will use the token generated
when running diffusers-cli login (stored in ~/.huggingface).
revision (str, optional, defaults to "main") β€”
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.
subfolder (str, optional, defaults to "") β€”
In case the relevant files are located inside a subfolder of the model repo (either remote in
huggingface.co or downloaded locally), you can specify the folder name here.
mirror (str, optional) β€”
Mirror source to accelerate downloads in China. If you are from China and have an accessibility
problem, you can set this option to resolve it. Note that we do not guarantee the timeliness or safety.
