From 2192193677c6d4823332ee740cca4857304fefee Mon Sep 17 00:00:00 2001 From: Haipeng Wang Date: Fri, 17 Sep 2021 14:54:59 +0800 Subject: [PATCH] add inplace op support to prune, scale_op is no longer need in jit.save (#35730) * add scale_op in model save step is not necessary, just fix the prune method to support static graph and inplace op * fix jit.save, no need to add scale_op to each outputvar anymore. fix prune_with_input, now it supports inplace op * temporarily disable test_trt_dynamic_shape.TRTDynamicShapeOutOfBound2Test --- paddle/fluid/framework/prune.cc | 36 +++++++++++++++++++ python/paddle/fluid/framework.py | 22 ++++++++++-- python/paddle/fluid/io.py | 15 ++++---- .../ir/inference/test_trt_dynamic_shape.py | 21 ++++++----- 4 files changed, 76 insertions(+), 18 deletions(-) diff --git a/paddle/fluid/framework/prune.cc b/paddle/fluid/framework/prune.cc index d0558abaf51..b577608de6c 100644 --- a/paddle/fluid/framework/prune.cc +++ b/paddle/fluid/framework/prune.cc @@ -180,6 +180,35 @@ void prune_impl(const proto::ProgramDesc& input, proto::ProgramDesc* output, for (auto op_iter = ops.rbegin();
