Failed to load GPU Faiss: name 'GpuIndexIVFFlat' is not defined. error in FAISS-CPU 1.10.0

[kungmo]

Hello,

I have been using faiss-cpu for several months since I don't need faster calculation for vector similarity searching. However, after upgrading FAISS-CPU from version 1.8.0 to 1.10.0 today, I encountered an error when loading faiss:

'Failed to load GPU Faiss: name 'GpuIndexIVFFlat' is not defined. Will not load constructor refs for GPU indexes.' error in FAISS-CPU'

I tried uninstalling and reinstalling faiss-cpu, but the error persists.

Could you please help me resolve this problem?

Thank you.

it seems like you're trying to use GpuIndexIVFFlat that's not part of FAISS-CPU? To use that, you'd need to use FAISS GPU build
