Hi Debasish, In https://github.com/apache/spark/blob/master/docs/mllib-guide.mdDependencies section, the document talks about the native blas dependencies issue.
For netlib which breeze uses internally, if the native library isn't found, the jblas implementation will be used. Here is more detail about how to install native library in different platform. https://github.com/fommil/netlib-java/blob/master/README.md#machine-optimised-system-libraries Sincerely, DB Tsai ------------------------------------------------------- My Blog: https://www.dbtsai.com LinkedIn: https://www.linkedin.com/in/dbtsai On Wed, May 7, 2014 at 10:52 AM, Debasish Das <debasish.da...@gmail.com>wrote: > Hi, > > How do I load native BLAS libraries on Mac ? > > I am getting the following errors while running LR and SVM with SGD: > > 14/05/07 10:48:13 WARN BLAS: Failed to load implementation from: > com.github.fommil.netlib.NativeSystemBLAS > > 14/05/07 10:48:13 WARN BLAS: Failed to load implementation from: > com.github.fommil.netlib.NativeRefBLAS > > centos it was fine...but on mac I am getting these warnings.. > > Also when it fails to run native blas does it use java code for BLAS > operations ? > > May be after addition of breeze, we should add these details on a page as > well so that users are aware of it before they report any performance > results.. > > Thanks. > > Deb >
