I am learning deep learning, and use deeplearning4J tuts. But when i run example code, some issue there :

Caused by: java.lang.UnsatisfiedLinkError: no jnind4j in java.library.path

i have tried some solutions on web but it doesnot work. So, if you know how to fix it, help me.

You need to unzip cuda-9.1-7.1-1.4.1-windows-x86_64.jar and nd4j-cuda-9.1-1.0.0-beta-windows-x86_64.jar somewhere, and add the paths to the native dlls to the java.library.path property when launching your app.

For example:

-Djava.library.path=C:\<path where you unzipped>\cuda-9.1-7.1-1.4.1-windows-x86_64\org\bytedeco\javacpp\windows-x86_64;C:\<path where you unzipped>\nd4j-cuda-9.1-1.0.0-beta-windows-x86_64\org\nd4j\nativeblas\windows-x86_64

I have a feeling its most likely an issue on my end but i really followed all the steps as best i could.

I had the same problem. But the issue was I was using the wrong import , nd4j-native. Instead of that I used nd4j-native-platform import and it fixed the problem. Hope it helps.

We're in the process of improving our CUDA implementation, and expect things to be working better there after the next nd4j release (should be out within a week).

I will try to answer this here, but usually this is where the chat comes in handy (a lot of asking about your environment and back and forth here..)

I'd try to answer this here, but the native code (especially with the examples) should run fine.

You could also try filing an issue: https://github.com/deeplearning4j/dl4j-examples/issues

In the mean time, read up on what an nd4j backend is: http://nd4j.org/backend.html

This SHOULD be the only dependency you need to run: http://search.maven.org/#artifactdetails%7Corg.nd4j%7Cnd4j-native-platform%7C0.6.0%7Cjar

The examples run out of the box for everyone we've talked to.

You don't seem to be doing anything out of the ordinary.

An alternative might just be using the nd4j-native artifact id with the appropriate classifier.

This is where you modify the nd4j backend: https://github.com/deeplearning4j/dl4j-examples/blob/master/dl4j-examples/pom.xml#L64

You can try just getting rid of this and replacing it with 1 of the artifact ids I told you about. If that doesn't fix it, I would recommend coming in to gitter.

However, sometimes bottlenecks or misconfiguration issues may limit performance to well below the maximum.
