Exception in thread "main" java.lang.UnsatisfiedLinkError on darwin-cpu-x86_64

Hi

Very eager to test this API! But gave up the first time and noticed quite active development. Gave it another try now. Since I am not an expert in native library linking I still fail at the basics:

1. This is what is in my sbt: resolvers += Resolver.sonatypeRepo("snapshots") libraryDependencies += "org.platanios" %% "tensorflow" % "0.1.0-SNAPSHOT" classifier "darwin-cpu-x86_64"

2. My exception:

Many thanks and sorry for the amateurish question

After fooling around on different stackoverflow threads etc. I found that SIP (Security Integrity Protection) is preventing @rpath to work on Mac OSX. To overcome that problem I ran :

install_name_tool -addrpath /private/var/folders/0/7cysl_6s31v9904lxcgshlww0000gn/T/tensorflow_scala_nativelibraries7260031192430581912/ /private/var/folders/0/7cysl_6s31v9904lxcgshlww0000gn/T/tensorflow_scala_native_libraries7260031192430581912/libtensorflow_jni.so

This solved it, but is rather impractical since this needs to be done runtime.:(

@tarjeir Thanks a lot for giving this API a try. I really hope you find it useful. I'm sorry about the issue you've been having. It seems that loading the dynamic libraries correctly for multiple systems has been eventful. I have created a new issue, #41, to aggregate all these concerns and resolve this for everyone. I'll close this issue and we can continue the conversation and resolution there.
