      numpy.int16, numpy.int32, numpy.int64, numpy.uint8,
      numpy.uint16,numpy.uint32, numpy.uint64)):
      return int(obj)
      elif isinstance(obj, (numpy.float_, numpy.float16, numpy.float32,
      numpy.float64)):
      return float(obj)
      elif isinstance(obj, (numpy.ndarray,)): # add this line
      return obj.tolist() # add this line
