From 85b77232768b53ee3db2f86653eeeedccbf570d1 Mon Sep 17 00:00:00 2001 From: Liu-xiandong <85323580+Liu-xiandong@users.noreply.github.com> Date: Mon, 11 Oct 2021 19:53:53 +0800 Subject: [PATCH] Add nn.functional.sparse_attention and some test cases, test=develop (#35757) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add paddle.nn.functional.sparse_attention API 本个PR主要将sparse_attention功能在python层进行了一层封装，OP的主体代码见：#PR35676 此外，对于封装的python 接口，增加了相应的单测。 --- paddle/fluid/operators/CMakeLists.txt | 2 +-
