If you use social media, you may see an image or images generated by machine learning technology recently.
DALLE 2
https://openai.com/dall-e-2/
Then recently another one has been released. That is Stable Diffusion. It is pretty similar to DALLE 2. If you give text and some parameters, it generates pretty nice image. You can use Stable Diffusion without waiting for a month which is super nice, right? However, it requires a GPU. If you don't have a GPU or cannot access to a GPU probably you 😠(What am I supposed to do?)
About Stable Diffusion
https://stability.ai/blog/stable-diffusion-public-release
A latent text-to-image diffusion model
Then you can try stable_diffusion.openvino. You don't need a GPU to run this!!!

The readme is very straightforward, so probably you won't have any issues to run the demo.py and try a python script for streamlit.
However, there might be an issue if you use python already with python version manager and anaconda or etc.
Then, you can use poetry to avoid messing up and keep your python dev env clean.
install poetry
There are 2 ways to install poetry.
using pip
using curl
Installationhttps://python-poetry.org/docs/#installation
Create a project folder
$ poetry new poetry-stable-diffusion

Install packages
$ poetry add package_name@package_version

However, you don't need to do this. You can use the following pyproject.toml I tested already.
In this case, I used python 3.8.12.[pyenv](https://github.com/pyenv/pyenv).
[tool.poetry]
name = "stablediffusion"
version = "0.1.0"
description = "test Stable Diffusion"
authors = [ "koji" ]
[tool.poetry.dependencies]
python = "^3.8"
numpy = "1.19.5"
transformers = "4.16.2"
diffusers = "0.2.4"
tqdm = "4.64.0"
openvino = "2022.1.0"
huggingface-hub = "0.9.0"
streamlit = "1.12.0"
watchdog = "2.1.9"
opencv-python = "4.5.2.54"
scipy = "1.6.1"
[tool.poetry.dev-dependencies]
[build-system]
requires = ["poetry-core> = 1.0 . 0 "]
build-backend = "poetry.core.masonry.api"

What you need to do set up the env is to run one command!
$ poetry install
Enter fullscreen mode
Exit fullscreen mode
Clone repo
$ git clone https://github.com/bes-dev/stable_diffusion.openvino.git
$ cd stable_diffusion.openvino
Enter fullscreen mode
Exit fullscreen mode
Run demo.py
$ poetry run python demo.py --prompt "cyberpunk New York City"

The generating process will take a few minutes (in my case it takes around 3 minutes)

Stable Diffusion is a latent text-to-image diffusion
model.
Thanks to a generous compute donation from Stability AI and support from LAION, we were able to train a Latent Diffusion Model on 512x512 images from a subset of the LAION-5B database.
Similar to Google's Imagen,
this model uses a frozen CLIP ViT-L/14 text encoder to condition the model on text prompts.
With its 860M UNet and 123M text encoder, the model is relatively lightweight and runs on a GPU with at least 10GB VRAM.
See this section below and the model card.
