Previous tutorial on Automatic1111, showing how to install Git and Python:

Git:

Python 3.10.6:

ComfyUI:

ComfyUI Manager:

Extended Save Image for ComfyUI:

.........................................

It is assumed that you already have Git and Python 3.10.6 installed.
If this is not the case, watch the previous tutorial (top link) if needed.

PowerShell commands relevant for installing ComfyUI dependencies in a Python Virtual Environment:

cd ComfyUI

python -m venv venv

Then you may continue with installing the dependencies as per the original installation instructions.

Hardware requirements:

NVIDIA dedicated GPU with minimum 6 GB of VRAM

This tutorial demonstrates to KTH Architecture students how to install the ComfyUI web user interface for Stable Diffusion – a node-based UI offering more flexibility than Automatic1111 and similar web user interfaces – and briefly covers the generation of images with the installed software.

The operating system used for this tutorial is Windows 10. Running another operating system (e.g. Linux, MacOS) might amount to a different user experience or software incompatibility.

If you want to check in which computer room(s) any relevant software might be installed in – CADLAB, DFL, and ARCPLAN are in the KTH School of Architecture building – please check the following link for current status:

Disclaimer:
This tutorial aims to increase student awareness of the versatility of the digital tools available for use within the context of the architectural education offered by KTH. As such, it might not be generally applicable, but on the other hand, if at least one architecture student is helped by it in fulfilling deliverables requirements or being taught something of genuine interest, the purpose of this tutorial is satisfactorily achieved. There might be inaccuracies in this tutorial – if you identify any significant one, please tell us in the comments.
