Tarball

Check it, unpack it, start PXA Control.

sha256sum -c pxa-v3.1-linux-x86_64-cuda12.8-sm60_61_70.tar.gz.sha256
tar xzf pxa-v3.1-linux-x86_64-cuda12.8-sm60_61_70.tar.gz

Container

The same v3.1 binaries as an image.

docker run -d --name pxa --gpus '"device=0,1"' --shm-size=1g \
  -p 8080:8080 -v /path/to/models:/models:ro \
  -v pxa-cache:/work/.cache/pxa \
  ghcr.io/poisonxa16/pxa:v3.1

Where --gpus fails with an ldcache error (Unraid among them), use --runtime=nvidia -e NVIDIA_VISIBLE_DEVICES=0,1.
