@cosmincatalin this is because your NDarrays are not deallocated
automatically, you can use ResourceScope, like this:
`ResourceScope.using(new ResourceScope()) {
val bareArray =
row.getAs[Seq[Double]](fieldName).map(_.toFloat).toArray
val shape = schema.getShape(fieldName)
val transposedShape = shape.reverse
val expectedSize = shape.product
val paddedArray = bareArray.padTo(expectedSize, 0f)
NDArray.array(paddedArray, Shape(transposedShape),
ctx).T.reshape(Shape(List(1, 1) ++ shape: _*)).toArray
}`
to automatically close NDarrays
