Projects

OnnxStack.StableDiffusion

Inference Stable Diffusion with C# and ONNX Runtime

Prompt

Stable Diffusion models take a text prompt and create an image that represents the text.

Example: High-fashion photography in an abandoned industrial warehouse, with dramatic lighting and edgy outfits, detailed clothing, intricate clothing, seductive pose, action pose, motion, beautiful digital artwork, atmospheric, warm sunlight, photography, neo noir, bokeh, beautiful dramatic lighting, shallow depth of field, photorealism, volumetric lighting, Ultra HD, raytracing, studio quality, octane render

Negative Prompt

A negative prompt can be provided to guide the inference to exclude in calculations

Example:

painting, drawing, sketches, monochrome, grayscale, illustration, anime, cartoon, graphic, text, crayon, graphite, abstract, easynegative, low quality, normal quality, worst quality, lowres, close up, cropped, out of frame, jpeg artifacts, duplicate, morbid, mutilated, mutated hands, poorly drawn hands, poorly drawn face, mutation, deformed, blurry, glitch, deformed, mutated, cross-eyed, ugly, dehydrated, bad anatomy, bad proportions, gross proportions, cloned face, disfigured, malformed limbs, missing arms, missing legs fused fingers, too many fingers,extra fingers, extra limbs,, extra arms, extra legs,disfigured,

Schedulers

Many different scheduler algorithms can be used for this computation, each having its pro- and cons. So far OnnxStack.StableDiffusion as included LMS Discrete, Euler Ancestral and DDPM options with more in the works.

Text To Image

Text To Image Stable Diffusion is a powerful machine learning technique that allows you to generate high-quality images from textual descriptions. It combines the capabilities of text understanding and image synthesis to convert natural language descriptions into visually coherent and meaningful images

Image To Image

Image To Image Stable Diffusion is an advanced image processing and generation method that excels in transforming one image into another while preserving the visual quality and structure of the original content. Using stable diffusion, this technique can perform a wide range of image-to-image tasks, such as style transfer, super-resolution, colorization, and more

   Prompt: Dog wearing storm trooper helmet, head shot

Getting Started

ONNX Model Download

You will need an ONNX compatible model to use, Hugging Face is a great place to download the Stable Diffusion models

Download the ONNX Stable Diffusion models from Hugging Face.

• Stable Diffusion Models v1.4
• Stable Diffusion Models v1.5

Once you have selected a model version repo, click Files and Versions, then select the ONNX branch. If there isn't an ONNX model branch available, use the main branch and convert it to ONNX. See the ONNX conversion tutorial for PyTorch for more information.

Clone the model repo:

git lfs install
git clone https://huggingface.co/runwayml/stable-diffusion-v1-5 -b onnx

Hardware Requirements

You can choose between Cpu and DirectML(GPU) for inference, Other Microsoft.ML.OnnxRuntime.* executors like Cuda may work but are untested

Cpu > 12GB RAM

DirectML > 10GB VRAM
