We provide JARs for CentOS 6 which make it possible to use Caffe with CPUs.

To use them, replace the relevant lines in your build.sbt with the following ones:

resolvers += "javacpp" at "http://www.eecs.berkeley.edu/~rkn/snapshot-2016-03-05/"
resolvers += "javacpp" at "http://www.eecs.berkeley.edu/~rkn/snapshot-2016-03-23-CENTOS6-CPU/"

libraryDependencies += "org.bytedeco" % "javacpp" % "1.2-SPARKNETCENTOS6"

libraryDependencies += "org.bytedeco.javacpp-presets" % "caffe" % "rc3-1.2-SPARKNETCENTOS6"

libraryDependencies += "org.bytedeco.javacpp-presets" % "caffe" % "rc3-1.2-SPARKNETCENTOS6" classifier "linux-x86_64"

libraryDependencies += "org.bytedeco.javacpp-presets" % "opencv" % "3.1.0-1.2-SPARKNETCENTOS6"

libraryDependencies += "org.bytedeco.javacpp-presets" % "opencv" % "3.1.0-1.2-SPARKNETCENTOS6" classifier "linux-x86_64"

libraryDependencies += "org.bytedeco.javacpp-presets" % "tensorflow" % "master-1.2-SPARKNET"

libraryDependencies += "org.bytedeco.javacpp-presets" % "tensorflow" % "master-1.2-SPARKNET" classifier "linux-x86_64"

and uncomment

test in assembly := {}

to make sure tests are not run during assembly (the TensorFlow tests would not work on CentOS 6).

There are instructions in 61b0cbc merged in #113 on how these JARs were build, in case you need to create your own.
