Bash script to easily install and launch AUTOMATIC1111's Stable Diffusion WebUI.

This Bash script primarily addresses the compatibility issue between PyTorch and Python v3.11 that arises during the installation of 'webui.sh' on Fedora 37. The incompatibility issue is indicated on the screen with the following error message:

  ERROR: Could not find a version that satisfies the requirement torchvision==0.14.1+cu117
  (from versions: 0.1.6, 0.1.7, 0.1.8, 0.1.9, 0.2.0, 0.2.1, 0.2.2, 0.2.2.post2, 0.2.2.post3)**  
  ERROR: No matching distribution found for torchvision==0.14.1+cu117**

Additionally, the script includes some basic checks and tips during the installation process to avoid common issues.

Use this script for both the initial installation and each subsequent attempt to launch Stable Diffusion Web UI (at least until PyTorch becomes compatible with the version of Python included in Fedora).

To perform the initial installation, run the following commands, replacing <your-directory> with a directory name of your choice:

#### Note that the last parameter of the git clone command is a dot '.'
mkdir <your-directory>
cd <your-directory>
git clone https://github.com/martin-rizzo/FedoraDiffusionLauncher.git .
./sdlauncher.sh

The directory structure after installation should look like this:

<your-directory>
    ├── stable-diffusion-webui/
    ├── venv/
    ├── README.MD
    └── sdlauncher.sh

Once Stable Diffusion Web UI is installed, to launch it again, navigate to the installation directory and run the script:

cd <your-directory>
./sdlauncher.sh

This issue arises because the version of PyTorch being used does not support Python versions higher than v3.10. Fedora 37 includes a newer version that is incompatible, and there is no easy way to downgrade it.

This script generates a virtual environment using "Python3.10", downloads "webui.sh" from AUTOMATIC1111's official repository, and executes it within the virtual environment.

The script attempts to automate this process as much as possible. However, if any human intervention is necessary, it displays easily understandable messages.

The script is currently in an experimental phase, and while there is a functional version available, I am still working on making adjustments and improvements. Please note that using this version in production or critical environments is not recommended, as there may be limitations and errors that I need to resolve.

Thank you for your understanding and support.
