From 0b5af9f2751ad6cb7ce76c577a6e67abe6dc8aa1 Mon Sep 17 00:00:00 2001 From: Georgios Pinitas Date: Fri, 19 Jun 2020 23:22:08 +0100 Subject: COMPMID-3478: Allow SubTensors with XY indexing Remove limitations on sub-tensor creation and allow any possible indexing as long as it honors the parent tensor shape. In case of padding expansion on a subtensor, an error is raised if the sub-tensor is indexed on the XY dimensions.
