Diffusers

A Unity package to run pretrained diffusion models with Unity Sentis

OpenUPM · Documentation (coming soon) · Feedback/Questions

About

This is essentially a port of Hugging Face’s diffusers library.

As of today only a limited number of pipelines and schedulers are supported (see below).

Installation

via OpenUPM

1. In Edit -> Project Settings -> Package Manager, add a new scoped registry:

   Name: Doji
   URL: https://package.openupm.com
   Scope(s): com.doji
   

2. In the Package Manager install com.doji.diffusers either by name or select it in the list under Package Manager -> My Registries

3. For the time being, you also have to use a custom fork of Sentis: In the package Manager -> Package Manager -> Install package from git URL-> https://github.com/julienkay/com.unity.sentis.git
