ComfyUI on Linux AMD

[TanOneDeg]

I'm having a difficult time installing ComfyUI on my HP AMD Ryzen 7 PRO 5850U processor laptop running POP O/S. For those in the know, I would appreciate some help. I followed the instructions on CofmUI Github for Linux. I'm getting the an error;

ww@pop-os:~/ComfyUI$ python3 main.py

The AMD mentioned in the instruction refers to GPU, not CPU.
You need to install according to your GPU spec.

I did follow the instructions to install the AMD GPUs for Linux only. I haven't a clue if I need to do something specific related to my particular GUP specification? If so, I'm all ears, or please share a link where I can find out if you can.

I had the same issue on Ubuntu 24.04. It turned out to have a simple solution.
I installed rocminfo to see if the GPU shows up at all, which it did, out of the box. No need to install anything.
To access rocm in a user environment, you need to add your username to the "render" and "video" groups.

sudo usermod -a -G render username
sudo usermod -a -G video username

Do a full reboot.
I'd suggest to add that to the installation instructions ...
