DL4J UnsatisfiedLinkError: no jniopenblas in java.library.path

I tried to set up a deeplearning4j project via gradle, but I get an UnsatisfiedLinkError:

My dependencies look like:

dependencies {
    compile group: 'org.deeplearning4j', name: 'deeplearning4j-core', version: '0.9.1'
    compile group: 'org.deeplearning4j', name: 'rl4j', version: '0.9.1'
    compile group: 'org.nd4j', name: 'nd4j-native', version: '0.9.1'
    compile group: 'org.nd4j', name: 'nd4j-jblas', version: '0.9.1'
    compile group: 'org.nd4j', name: 'nd4j-api', version: '0.9.1'
    compile 'org.nd4j:nd4j-native:0.9.1:windows-x86_64'
}

I've also tried to add

compile group: 'org.bytedeco.javacpp-presets', name: 'openblas', version: '0.2.20-1.3'

but that didn't help.

Do I need to install OpenBlas? I didn't read such a thing in the Quick Start Guide for deeplearning4j. OS is Win10, IDE is IntelliJ Community Edition.

nd4j-jblas isn't even a valid maven dependency. Where did you get that from exactly?

We don't have nd4j-jblas anywhere in our docs and it hasn't existed for nearly 2 years now. Stick to our getting started docs: http://deeplearning4j.org/quickstart

We explain what you need in there. Rather than messing with all the classifiers just use: nd4j-native-platform for the artifact id.
