torch.nn.Module
Disco Diffusion (DD) is a Google Colab Notebook which leverages an AI Image generating technique called CLIP-Guided Diffusion to allow you to create compelling and beautiful images from just text inputs. Created by Somnai, augmented by Gandamu, and building on the work of RiversHaveWings, nshepperd, and many others.

- Parameters
unet (ModelType) – Config of denoising Unet.
diffusion_scheduler (ModelType) – Config of diffusion_scheduler scheduler.
secondary_model (ModelType) – A smaller secondary diffusion model trained by Katherine Crowson to remove noise from intermediate timesteps to prepare them for CLIP. Ref: https://twitter.com/rivershavewings/status/1462859669454536711 # noqa Defaults to None.
clip_models (list) – Config of clip models. Defaults to [].
use_fp16 (bool) – Whether to use fp16 for unet model. Defaults to False.
pretrained_cfgs (dict) – Path Config for pretrained weights. Usually this is a dict contains module name and the corresponding ckpt path. Defaults to None.
