Hi, I installed graphvite from source with comand

cd build && cmake .. && make && cd -

but raise

just like issue in faiss. but I have install openblas

my envs:

• CUDA

• open blas

sudo yum install openblas

Nothing to do

Thanks

Could you describe where such error occurs?

Thank you for your reply, I described the problem in detail.

I'm not very familiar about the autoconf routine in faiss. In my case, faiss always works with mkl, a kind of BLAS. If you follow the instructions to install the requirements in conda, I think faiss should find mkl.

I had the same problem

@bangdo172 I just checked on a bunch of environments and didn't reproduce this error. I think mkl should work if you are using Intel CPUs.

If it still doesn't work, a workaround might be

• manually install openBLAS or mkl
• compile faiss from source
• compile graphvite with cmake .. -DFAISS_PATH=/path/to/faiss/ && make

Faiss is only used by the visualization application in graphvite. I will add some compilation options so that you can skip the compilation of faiss.
