From 3687ee1e7719436ff155a35911946b045903e8b6 Mon Sep 17 00:00:00 2001 From: Sang-Hoon Park Date: Wed, 24 Jun 2020 13:34:04 +0100 Subject: COMPMID-3539: Ignore align_corners for scaled size of 1 Scale kernels failed to validate when align_corners is true for scaled output size 1. Change this behavior to ignoring align_corners value to be aligned with expected behavior of higher-level frameworks. Also the minimum output size generated by the fixture for Scale kernels is changed to 1.
