From f72729d407fcc33ad5de5f6285637c45a1425d5a Mon Sep 17 00:00:00 2001 From: Yu Yang Date: Tue, 7 Nov 2017 17:37:30 -0800 Subject: [PATCH] Feature/rnn to array to lod tensor (#5411) * Add LoDRankTable LoD Rank Table stores the `level` of `lod` which is ordered by sequence length in descending order. It is useful when implement dynamic RNN and is shared by dynamic RNN memory, dynamic RNN slice input and dynamic RNN slice output operators. * Add skeleton for array_to_lod_tensor and lod_tensor_to_array * Add VarType::LoDTensorArray * Add PyBind of LoDTensorArray * Add InferVarType * Add first unittest * Add ut * Add unittest * Add unittest * Add unittests * update * init * add infershape for lod_tensor_to_array_op * compelete array_to_lod_tensor_op * copy data * clean code * clean code * Fix unittest data * fix bugs * fix compile error * Refine TensorToArrayOp * refactor array_to_lod_tensor * Unittest * fix bugs * Fix unittest * Fix unittest * debug * Debug * Fix unittest * clean code * refactor * use ostream * update test * fix gpu build error * make gpu test pass --- paddle/framework/ddim.cc | 2 +- paddle/framework/ddim.h | 2 +- paddle/framework/lod_rank_table.cc | 1 + paddle/framework/lod_tensor.cc | 50 +++--- paddle/framework/lod_tensor.h | 9 +- paddle/framework/lod_tensor_test.cc | 39 ++--- paddle/framework/var_desc.cc | 6 +- paddle/operators/CMakeLists.txt | 4 + paddle/operators/array_to_lod_tensor_op.cc | 152 ++++++++++++++++++ paddle/operators/lod_rank_table_op.cc | 1 + paddle/operators/lod_tensor_to_array_op.cc | 143 ++++++++++++++++ python/paddle/v2/framework/layers.py | 24 +++ .../v2/framework/tests/test_lod_rank_table.py | 1 - .../tests/test_lod_tensor_array_ops.py | 127 +++++++++++++++ 14 files changed, 514 insertions(+), 47 deletions(-) create mode 100644 paddle/operators/array_to_lod_tensor_op.cc create mode 100644 paddle/operators/lod_tensor_to_array_op.cc create mode 100644 python/paddle/v2/framework/tests/test_lod_tensor_array_ops.py diff --git a/paddle/framework/ddim.cc b/paddle/framework/ddim.cc index 239ae5e123..10c785e04c 100644 --- a/paddle/framework/ddim.cc +++ b/paddle/framework/ddim.cc @@ -117,7 +117,7 @@ int64_t DDim::operator[](int idx) const { return boost::apply_visitor(DynamicConstIndexer(idx), var);
