From 228506618b23845792d7f6de74cb6b97cd7bfb13 Mon Sep 17 00:00:00 2001 From: Xin Pan Date: Fri, 12 Oct 2018 14:41:57 +0800 Subject: [PATCH] Avoid GetMutable implicitly reset Var Type. This can cause a lot of problem: 1. Wrong operator implementation, Op can get a wrong type without failure. 2. Anytype can be Get without defined in VarType. Also fix wrong STEP_SCOPE usage. test=develop --- paddle/fluid/framework/executor.cc | 2 +- paddle/fluid/framework/feed_fetch_method.cc | 3 +-- paddle/fluid/framework/naive_executor.cc | 2 +- paddle/fluid/framework/variable.h | 6 +++++- paddle/fluid/framework/variable_test.cc | 11 ++++++----- python/paddle/fluid/layers/io.py | 6 +++++- python/paddle/fluid/layers/tensor.py | 2 +- python/paddle/fluid/tests/book/test_word2vec.py | 16 ++-------------- 8 files changed, 22 insertions(+), 26 deletions(-) diff --git a/paddle/fluid/framework/executor.cc b/paddle/fluid/framework/executor.cc index 70ec6e90a4..a070b8efb8 100644 --- a/paddle/fluid/framework/executor.cc +++ b/paddle/fluid/framework/executor.cc @@ -66,7 +66,7 @@ void InitializeVariable(Variable* var, proto::VarType::Type var_type) { } else if (var_type == proto::VarType::FETCH_LIST) { var->GetMutable(); } else if (var_type == proto::VarType::STEP_SCOPES) { - var->GetMutable>(); + var->GetMutable>(); } else if (var_type == proto::VarType::LOD_RANK_TABLE) { var->GetMutable(); } else if (var_type == proto::VarType::LOD_TENSOR_ARRAY) { diff --git a/paddle/fluid/framework/feed_fetch_method.cc b/paddle/fluid/framework/feed_fetch_method.cc index 8e1f93c5eb..3e9353f5cf 100644 --- a/paddle/fluid/framework/feed_fetch_method.cc +++ b/paddle/fluid/framework/feed_fetch_method.cc @@ -27,8 +27,7 @@ void SetFeedVariable(Scope* scope, const LoDTensor& input, // be created.
