From df8db345523f03b2163febe97a4cf07446b28230 Mon Sep 17 00:00:00 2001 From: "Guo, Yejun" Date: Mon, 29 Jul 2019 09:56:33 +0800 Subject: dnn: add layer pad which is equivalent to tf.pad the reason to add this layer first is that vf_sr uses it in its tensorflow model, and the next plan is to update the python script to convert tf.pad into native model.
