IllegalStateException: ERROR: Unable to run session Expects arg[0] to be uint8 but int32 is provided || Unsupported data type: UBYTE

Question

Trying to run RunGraphExample frozen_graph.pb on trained model Faster-RCNN with Tensorflow 1.13.1 , org.deeplearning4j "1.0.0-beta6" (Tensorflow 1.15)

val data: Array[Array[Int]] = new Array[Array[Int]](img.getWidth * img.getHeight);
    for (i <- 0 until img.getWidth) {
      for (j <- 0 until img.getHeight()) {
        val ar: Array[Int] = new Array(3)
        ar(0) = color.getRed.byteValue() & 0xff
        ar(1) = color.getGreen.byteValue() & 0xff
        ar(2) = color.getBlue.byteValue() & 0xff
        data(i * img.getHeight + j) = ar
      }
    }
var arr: INDArray = Nd4j.createFromArray(data) 
//.castTo( org.nd4j.linalg.api.buffer.DataType.UBYTE)

Error appears at line inputMap.put(inputs.get(0), shapedArray)

if shapedArray is int then error is :

Unable to run session Expects arg[0] to be uint8 but int32 is provided

If shapedArray is short or .castTo(UBYTE) then error is :

Unsupported data type: UBYTE
or
Unsupported data type: SHORT

From about 1.0.0-beta3 Deeplearning4j removed support of val compressor = BasicNDArrayCompressor.getInstance.setDefaultCompression("UINT8")

How can I correctly convert image to INDArray with uint8 DataType?
