@param {Object} output The output of the model.
@param {Tensor} output.logits Classification logits (including no-object) for all queries.
@param {Tensor} output.pred_boxes Normalized boxes coordinates for all queries, represented as (center_x, center_y, width, height).
These values are normalized in [0, 1], relative to the size of each individual image in the batch (disregarding possible padding).
