after tracking the code i understand sub_sp_info and ob_sp_info get no value in anyplace of this code.
to make sure sen it directly to fully connected layer
**sub_fc = slim.fully_connected(sub_fc, cfg.VTR.VG_R, activation_fn=tf.nn.relu, scope='RD_sub_fc')
ob_fc = slim.fully_connected(ob_fc, cfg.VTR.VG_R, activation_fn=tf.nn.relu, scope='RD_ob_fc')**
and you recive this errro:
**InvalidArgumentError: You must feed a value for placeholder tensor 'Placeholder_3' with dtype float and shape [30,4] [[{{node Placeholder_3}}]]**
