ROCm 7.1.1 + ComfyUI Automated Installer (Ubuntu 25.10)

###############################################
# This script is a full automated ComfyUI installation with ROCm 7.1.1 for
# Ubuntu 25.10. Nevertheless, it should work in most Linux distros. Just take
# care on the versions of the PyTorch wheels which should fit to your Python
# version.
#
# This script was originally published on
# [Reddit](https://www.reddit.com/r/ROCm/comments/1p9s0dr/comment/nu5ibgw/) for
# Ubuntu 24.04 and I took it as is and modified it to fit for Ubuntu 25.10.

Oh this is bloody amazing ! I've been really struggling to get stuff to work nicely on Windows, so I came to ubuntu and struggled more until I found this.
More or less every tutorial I found had some kind of issue I couldn't get around somewhere but this did loads without a single error and works a treat !!
Thank you so much !!!

P.s. You wouldn't do one for AI toolkit also would you haha... I'd so love to make my own lora's.
