BLAS conflict when compile with Caffe support

Discussion

Hi guys, I encountered such a problem when compile MXNet with Caffe support. I set USE_BLAS=mkl for Caffe first and then for MXNet. But there are some errors related to BLAS conflict. Any suggestions would be really appreciated.

I’ve done this with openblas and it works. Never tried mkl. Does openblas work for you or do you see this problem with openblas too?

Em…I tried a naive way… just comment out those lines related to cblas and it works…

I didn’t try openblas because I need some sparse matrix calculation supported by MKL.
