This release is a pre-release and may not be stable for production use.
loom-py-rt-vulkan
The Vulkan backend for loom-py-rt. One shared library in one
small wheel; there is nothing here to import.
pip install "loom-py-rt[vulkan]"
import loom
loom.devices() # a Vulkan device now appears
model = loom.Model.from_file(path, device="gpu")
The base package is unchanged by installing this — it discovers the library on sys.path at import
and device="auto" starts using it. That is what GGML_BACKEND_DL buys: no second copy of the
runtime per accelerator.
If it appears not to have worked
Check loom.devices(). A backend whose driver is too old, or which finds no supported device, loads
without error and registers nothing — the only other symptom is a model running at CPU speed.
device="gpu" asks for an offload device with its own memory, preferring one the kernel confirms is a
GPU. It is not a promise that Vulkan specifically was chosen. Pass device="Vulkan0" to require this
backend.
Versioning
This package pins the base with ==, not ~=. It carries a libggml-vulkan.so that is dlopened
beside the base wheel's libggml-base.so, and ggml makes no ABI promise across revisions — so a base
release that moves its ggml pin invalidates every backend wheel published before it. The exact pin is
what stops pip from pairing two libraries that do not agree.
