What it means

Error "indices should have rank 1" thrown in tensorflow/models.

    boxlist: BoxList holding N boxes
    indices: a rank-1 tensor of type int32 / int64
    fields: (optional) list of fields to also gather from.  If None (default),
      all fields are gathered from.  Pass an empty fields list to only gather
      the box coordinates.
    use_static_shapes: Whether to use an implementation with static shape
      gurantees.

  Returns:
    subboxlist: a BoxList corresponding to the subset of the input BoxList
    specified by indices

  Raises:
    ValueError: if specified field is not contained in boxlist or if the
      indices are not of type int32
