[Stable Diffusion Web UI Colab](https://github.com/camenduru/stable-diffusion-webui-colab) is a fork project to deploy [AUTOMATIC1111's Stable Diffusion web UI](https://github.com/AUTOMATIC1111/stable-diffusion-webui) on [Google Colab](https://colab.research.google.com/).

Colab provides virtual machine with GPU, so you don't have to own a powerful GPU to enjoy AI computing. You can pay as you go with Google Colab.

And [stable diffusion webui colab v2.0](https://github.com/camenduru/stable-diffusion-webui-colab/tree/v2.0) is now available!

Here are some notes on how to use it.

## Basic Usage

`Stable Diffusion Web UI Colab` can be deployed easily using the given `.ipynb` file, which is a [Jupyter Notebook](https://jupyter.org/), and you can run it on [Google Colab](https://colab.research.google.com/) to deploy the Stable Diffusion web UI.

- First, you simply just need to click one of `Open in Colab` button in [the repository](https://github.com/camenduru/stable-diffusion-webui-colab/tree/v2.0) to open the notebook in Colab. Each button configures for a specific model.
- Then, you can run the notebook to deploy `A1111` by clicking the `run` button on top left corner of the notebook.
- After the deployment is finished, a gradio URL will show up in the output like `https://xxxxxxxxx.gradio.live` for you to open the web UI in your browser.

[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/camenduru/stable-diffusion-webui-colab/blob/main/stable/chillout_mix_webui_colab.ipynb)

The notebook you run will be something like this:

- Be sure you have selected `GPU` as the runtime type in Colab, otherwise the deployment will fail.

I just commented out the model download part and launch part, so I can download models manually before launching the web UI.

## Download Models

There is a built-in extension to download models from [Civitai](https://civitai.com/) in web UI, but you can also download models from other sources using `wget` command in notebook.

Google Colab can only run 1 piece of code at a time, to download models manually, you must first stop the running code by clicking the `stop` button on top left corner of the notebook, then run the following code to download models.

```ipynb
# Download models

```

## Launch Web UI

When you need to launch or restart the web UI, you can run the following code to launch it.

If you run into some error that says can't attach to GPU, make sure you have selected `GPU` as the runtime type in Colab.

```ipynb
# Launch
%cd /content/stable-diffusion-webui
!python launch.py --share --xformers --enable-insecure-extension-access --gradio-queue
```

## Copy Generated Images to Google Drive

There is a file explorer in Colab, but you can't download batch of files from it. 

The best way to download generated images I can think of is to zip them and save them to Google Drive.

Here's a piece of code to do so:

```ipynb
# Mount Google Drive, authorization modal will show up
from google.colab import drive
drive.mount('/content/drive')

# Zip images and save to Google Drive
%cd /content/stable-diffusion-webui/outputs 
!zip -r /content/drive/MyDrive/images.zip txt2img-images
```

Have fun generating images with Stable Diffusion!
