graxpert gpu torch

Kubuntu 26.04 running siril. 
remove whatever is at:

~/.local/share/siril

open a terminal there. Then it's simply:

pip3.12 -m venv venv
. venv/bin/activate

Siril was complaining about not being able to load some CUDA 13 stuff, so from here:
 https://pytorch.org/get-started/locally/
choose your poison

Then it's simply:
pip3 install torch torchvision

Launch siril now, and we get hw accellerateion:

02:06:46: Testing CUDAExecutionProvider...
02:06:46: OK: CUDAExecutionProvider ran successfully
02:06:46: Testing CPUExecutionProvider...

easy fix:
sudo apt dist-upgrade

29 jul 2026

nvidia purge

Because e.g. you're going to install a different gpu.

sudo apt purge 'nvidia-*' 'libnvidia-*'

 sudo apt autoremove --purge



Reboot afterward so the Nouveau driver is loaded again.

Shutdown, remove the power cable and hold the on button for a few seconds before removing and replacing hardware.

Then it's:

sudo ubuntu-drivers install

That's it.

Focus the moon until it is sharp. Keep that focus.

Here is the definitive solution:
