I've been testing Ollama on a Raspberry Pi 4 and I noticed that the default binary is not compiled for Vulkan. Vulkan on a Raspberry Pi 4 uses the Pi / Broadcom "GPU".

I've gotten the cmake builds to complete but there are a few errors and the go run . serve step doesn't seem to be coming up with Vulkan. If this should work, I'd be happy to gather documentation for a bug report.

extent analysis

TL;DR

Recompile the Ollama binary with Vulkan support enabled to resolve the issue.

Guidance

  • Verify that the cmake command includes the necessary flags to enable Vulkan support, such as -DVULKAN_ENABLE=ON.
  • Check the cmake output for any errors or warnings related to Vulkan support.
  • Ensure that the Raspberry Pi 4's Vulkan drivers are properly installed and configured.
  • Review the Ollama documentation to confirm the correct build and runtime configuration for Vulkan support.

Notes

The issue may be specific to the Raspberry Pi 4's Broadcom GPU, and additional configuration or dependencies may be required to enable Vulkan support.

Recommendation

Apply workaround: Recompile the Ollama binary with Vulkan support enabled, as this is likely to resolve the issue and allow for proper functionality on the Raspberry Pi 4.
