Can't Get ComfyUI Working; LInux: AMD GPU

[Ykcud]

For the last several days, I have been trying to get ComfyUI to work, but without much success. I have followed the instructions here for my configuration. Below is some information about what has transpired. A lot of it with fractured help from where I could get it:

I have:
Ryzen 5600X
32 GB of RAM @ 3600 MT/s
1 TB SSD with more than 300 GB of free space.
AMD 6700 XT (RDNA2, 12 GB of VRAM)

I am a novice with Linux.

I want to use Comfyui to generate images for TTRPGs. Maybe later for music and clip generation if that is a thing, but one step at a time.

linux Mint Cinnamon

Rocm 6.2 is installed. When attempting to install it, it shows it is already installed via terminal, stating after most lines "Requirement already satisfied".

Followed instructions for this link: https://github.com/comfyanonymous/ComfyUI#installing
Also installed Pytorch from https://pytorch.org/ with the following configuration:
Stable (2.5.1), Linux, Pip, Python, Rocm 6.2

Also followed instructions from November 16th post here: pytorch/pytorch#103973 (comment)

I have found that a lot of commands I have seen or been given require I put a 3 after "python". Otherwise, any command with just python" does not work.

I have installed comfyui requirements already via this command:
pip install -r requirements.txt

venv has been activated.

Used these commands per instructions from doctorpangloss to get comfyui running while I had my 5700XT:

python -m venv .venv
source .venv/bin/activate
pip install "comfyui[withtorch]@git+https://github.com/hiddenswitch/ComfyUI.git"
comfyui --create-directories
comfyui

However, it was using my CPU at the time and not seeing or using my GPU.

I also tried the following command at that time:

HSA_OVERRIDE_GFX_VERSION=10.3.0 python main.py

But it still used just my CPU.

I can no longer get ComfyUI to run at all after shutting it down. So I now have my RX 6700 XT in the system since it is newer than my 5700 XT and has 12 GB of VRAM vs 8 GB.

I have uninstalled rocm and reinstalled rocm 6.2, but get the following:

Compile with TORCH_USE_HIP_DSA to enable device-side assertions.

This is with the overide as well. Also used "python3 main.py --disable-cuda-malloc" which has the same result.

Followed instructions on 7/25/23 from link below, but got same results:

AUTOMATIC1111/stable-diffusion-webui#11900

As a not "rocminfo" does not work:

Command 'rocminfo' not found, but can be installed with:
sudo apt install rocminfo

After installing per above, just loops back to same message.
