Hi,
Sorry for such a late reply. I've been quite occupied with other projects recently... Anyway, to my knowledge, this issue should be easy to fix. You can either choose to set the label of background to -1 to ignore it when computing loss, or use tf.losses.compute_weighted_loss in front of tf.nn.sparse~. For more details, you can turn to TheRevanchist and JimmyCai91's comments in the following link:
