code: public static SparseTensor fromUnorderedKeyValues(int[] dimensionNumbers, int[] dimensionSizes,
        long[] keyNums, double[] values) {
      long[] keyNumsCopy = ArrayUtils.copyOf(keyNums, keyNums.length);
      double[] valuesCopy = ArrayUtils.copyOf(values, values.length);
      return fromUnorderedKeyValuesNoCopy(dimensionNumbers, dimensionSizes, keyNumsCopy, valuesCopy);
    }
docs: Similar to the constructor, except does not require
  {@code keyNums} to occur in ascending order.
