Solution

  • 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
