[generateme/fastmath "2.4.0"]
Important Note
Fastmath 2.3.0
depends on SMILE 3.0.x which is GPL. That means that Fastmath 2.3.0 also should be treated as GPL. Version 2.4.x
fixes it and brings back SMILE LGPL 2.x dependency.
Important Note
Fastmath relies on SMILE 2.6.0 which relies on BLAS/LAPACK via MKL and/or OpenBlas. MKL (preferred) and OpenBlas are included as dependencies in fastmath
. This leads to addional 1GB of jar files. I can't assure that all functionalities will work on OpenBlas (see: #15) but 99% should. If you need fastmath
to be lighter, please exclude MKL from your path.
[generateme/fastmath "2.4.0" :exclusions [com.github.haifengl/smile-mkl]]
{:deps {generateme/fastmath {:mvn/version "2.4.0"
:exclusions [com.github.haifengl/smile-mkl]}}}
If you don't need certain interpolation or clustering methods you can exclude OpenBlas as well (be warned that other things can break):
:exclusions [com.github.haifengl/smile-mkl org.bytedeco/openblas]
When MKL is not available fastmath
(SMILE actually, here and here) will throw two exceptions with full stack traces about lack of MKL. You can safely ignore them.
[main] DEBUG smile.math.blas.LAPACK - Failed to create MKL instance:
java.lang.ClassNotFoundException: smile.math.blas.mkl.MKL

[main] DEBUG smile.math.blas.BLAS - Failed to create MKL instance:

Since this library is only JVM version, you can check following Clojure/ClojureScript libraries as replacement
Java classes are compiled for java 1.8
If you see place of improvement, I'm accepting PRs.
