What is the issue?

Running gemma4 on the Intel ARC A750 platform and using Vulkan as the backend via environment variables, input images may cause internal label leakage, and it seems to only occur when calling the API endpoints.

extent analysis

TL;DR

  • Verify environment variables for Vulkan backend configuration to prevent internal label leakage on Intel ARC A750 with gemma4.

Guidance

  • Review the environment variables set for the Vulkan backend to ensure they are correctly configured for the Intel ARC A750 platform.
  • Check the gemma4 documentation for any specific requirements or recommendations for running on Intel hardware with Vulkan.
  • Test the API endpoints with different input images to isolate if the issue is specific to certain types of images or a broader problem.
  • Consider testing on a different platform or backend to determine if the issue is specific to the Intel ARC A750 or Vulkan configuration.

Notes

  • The issue seems to be related to the specific hardware and backend configuration, so solutions may vary depending on the exact setup.
  • Without more detailed log output or error messages, it's challenging to provide a more precise fix.

Recommendation

  • Apply workaround: Adjust environment variables and test with different images to mitigate the internal label leakage issue, as the root cause appears related to the configuration rather than a version-specific bug that would necessitate an upgrade.
