Keras import from trained model

Hi All, just getting started, and trying to import a model so that I can just do evaluations of it in the Java side. I’ve not been directly involved in training of the model, but given the keras model, I suppose I can consider this as a black box.

I’m just trying to read using the following:

String modelFile = “/home/ernest/Desktop/Test/Model_slideWin_S2048”;
Path modelPath = Paths.get(modelFile);

    System.err.println("reading model");
    byte[] bytes = Files.readAllBytes(modelPath);

    System.err.println("parsing model");
    ComputationGraph cg = null;
    try (InputStream modelInputStream = new ByteArrayInputStream(bytes)) {
        cg = KerasModelImport.importKerasModelAndWeights(modelInputStream);
    }

    System.err.println("read model");

but getting results:

reading model
parsing model
