Configuration

In Diffusers, schedulers of type schedulers.scheduling_utils.SchedulerMixin, and models of type ModelMixin inherit from ConfigMixin which conveniently takes care of storing all parameters that are passed to the respective __init__ methods in a JSON-configuration file.

TODO(PVP) - add example and better info here

ConfigMixin

class diffusers.ConfigMixin

< source >

( )

Base class for all configuration classes. Stores all configuration parameters under self.config Also handles all methods for loading/downloading/saving classes inheriting from ConfigMixin with

Class attributes:

config_name (str) — A filename under which the config should stored when calling save_config() (should be overridden by parent class).
ignore_for_config (List[str]) — A list of attributes that should not be saved in the config (should be overridden by parent class).

from_config

< source >

( pretrained_model_name_or_path: typing.Union[str, os.PathLike] return_unused_kwargs = False **kwargs )

Parameters

pretrained_model_name_or_path (str or os.PathLike, optional) — Can be either:
- A string, the model id of 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 save_config(), e.g., ./my_model_directory/.
cache_dir (Union[str, 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.
ignore_mismatched_sizes (bool, optional, defaults to False) — Whether or not to raise an error if some of the weights from the checkpoint do not have the same size as the weights of the model (if for instance, you are instantiating a model with 10 labels from a checkpoint with 3 labels).
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.
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.
output_loading_info(bool, optional, defaults to False) — Whether or not to also return a dictionary containing missing keys, unexpected keys and error messages.
local_files_only(bool, optional, defaults to False) — 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) — The token to use as HTTP bearer authorization for remote files. If True, will use the token generated when running transformers-cli 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.
subfolder (str, optional, defaults to "") — 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.

Instantiate a Python class from a pre-defined JSON-file.

It is required to be logged in (huggingface-cli login) when you want to use private or gated models.

Activate the special “offline-mode” to use this method in a firewalled environment.

save_config

< source >

( save_directory: typing.Union[str, os.PathLike] push_to_hub: bool = False **kwargs )

Parameters

save_directory (str or os.PathLike) — Directory where the configuration JSON file will be saved (will be created if it does not exist).

Save a configuration object to the directory save_directory, so that it can be re-loaded using the from_config() class method.
