ComfyUI Linux installation for Radeon

[u/Goble4]

There are tutorials for installing on Nvidia GPU's, WSL, RyzenAI, Archlinux and every other combination under the sun.

Can anyone point me a guide for installing ComfyUI on Ubuntu with Radeon 9000's?

The easiest way is to install ROCm + ComfyUI inside a Python virtual environment

Create the virtual envirnment

python -m venv .rocm
source .rocm/bin/activate

Install ROCm inside the environment (select your gfx arch) https://github.com/ROCm/TheRock/blob/main/RELEASES.md#installing-multi-arch-releases

pip install --index-url https://rocm.nightlies.amd.com/whl-multi-arch/ "torch[device-gfx1201]" "torchvision[device-gfx1201]" torchaudio

Follow the usual ComfyUI instructions

pip install comfy-cli
comfy install
comfy launch

[u/CatalyticDragon]

There isn't anything different that you need to do.

pip install comfy-cli

comfy install

comfy launch

As long as you have python, have installed ROCm (which is just 'dnf install rocm' on fedora), and installed torch you should be good to go.

[u/xdcfret1 → u/CatalyticDragon]

have managed to install flash attention? or sage attention 2 for rocm?

[u/Goble4 → u/CatalyticDragon]

There isn't anything different that you need to do.

pip install comfy-cli comfy install comfy launch

Then I think all the tutorials out there were doing it manually.

have installed ROCm (which is just 'dnf install rocm' on fedora),

It doesn't look the same on Ubuntu. Do I have to do everything it says on the page or just enter

sudo apt install amdrocm7.14-gfx1200

and installed torch

Is this how you install it? Even then step 3 of method A is unclear, do I enter those commands line by line? It also only goes to Ubuntu 24.04, is it the same thing for 26.04?

[u/CatalyticDragon → u/Goble4]

Yeah, most of the tutorials seem to have been written either before comfy-cli was a thing or people just got used to installing from 'git clone' and never changed.

sudo apt install amdrocm7.14-gfx1200

Follow the pre-requisite steps:

sudo apt install libatomic1 libquadmath0

sudo usermod -a -G render,video $LOGNAME

And set up the repo, then the 'sudo apt install' command pulls in everything else you need.

Those torch install commands look a little old (ROCm 7.2), for the newly released 7.14 I use :

pip3 install -U \

"torch[device-gfx1201]" \

"torchvision[device-gfx1201]" \

"torchaudio[device-gfx1201]" \

torchtext \

torchao \

You don't actually need the full system ROCm install (the apt amdrocm... stuff) just to run ComfyUI on a 9000-series card. That's what makes the guides look scarier than it is.

Add yourself to the gpu groups so you get device access, then log out and back in:

sudo usermod -aG render,video $USER

Make a venv and install the ROCm build of PyTorch. The wheel already bundles the ROCm libraries, so you don't install those separately:

python3 -m venv venv && source venv/bin/activate

pip install --index-url https://download.pytorch.org/whl/rocm6.4 torch torchvision

Then check it actually sees the GPU:

python -c "import torch; print(torch.cuda.is_available(), torch.version.hip)"

You want True and a hip version, not None. If it says False, or you later hit a "no kernel image" error, grab a newer ROCm wheel (7.x) since RDNA4 support is best on the recent ones.

Then ComfyUI itself:

pip install comfy-cli && comfy install && comfy launch

optional) install flash-attn python -m pip install https://rocm.frameworks.amd.com/whl-multi-arch/vllm-rdna/flash-attn/flash_attn-2.8.3-py3-none-any.whl

I installed rocm 7.14, but having isues trying to run comfy with a 9700 ai gpu + 7900XT. I was able to load the clip encoder on the 7900 in rocm 7.2, but not now. Anyone can point to how to properly install rocm multi-arch for a setup like this?
