Failed to run the example

[MrWWheat]

Hi,

I am trying to use this go-faiss library, and I just download this repo from github. My env is local Mac machine.

I have already copy the libfaiss_c.so to /usr/local/lib/libfaiss_c.so, but when I run the example by go run example.go, it shows:

# github.com/41tair/go-faiss/faiss

By any chance you know the possible reason? Thanks!

this so file is build for linux, you need rebuild libfaiss_c.so for darwin.
