1. Use KerasModelImport to load an external MultiLayerNetwork model:

String modelFileLocation = new ClassPathResource("kerasModel.h5").getFile().getPath();
 MultiLayerNetwork model = KerasModelImport.importKerasSequentialModelAndWeights(modelFileLocation);

2. Use KerasModelImport to load an external ComputationGraph model:

String modelFileLocation = new ClassPathResource("kerasModel.h5").getFile().getPath();
 ComputationGraph model = KerasModelImport.importKerasModelAndWeights(modelFileLocation);

3. Use KerasModelBuilder to import an external model:

KerasModelBuilder builder = new KerasModel().modelBuilder().modelHdf5Filename(modelFile.getAbsolutePath())
 .enforceTrainingConfig(trainConfigToEnforceOrNot);
 if (inputShape != null) {
 builder.inputShape(inputShape);
 }
 KerasModel model = builder.buildModel();
 ComputationGraph newModel = model.getComputationGraph();
