Subject: [PATCH 070/486] [Dy2stat] Fix the bug that loop_body_func may return
 single element (#31806)

Our old `loop_body` function may return single element when `loop_vars` just contains only 1 element, which can cause bug. The key point of this PR is forcing `loop_body` functions always return tuple.

+    By default, this operator implements the cross entropy loss function with softmax. This function 
     combines the calculation of the softmax operation and the cross entropy loss function 
-    to provide a more numerically stable gradient.

-/** \internal \class global_math_functions_filtering_base
-  *
-  * What it does:
-  * Defines a typedef 'type' as follows:
-  * - if type T has a member typedef
- * Eigen_BaseClassForSpecializationOfGlobalMathFuncImpl, then
-  *   global_math_functions_filtering_base<T>::type is a typedef for it.
-  * - otherwise, global_math_functions_filtering_base<T>::type is a typedef for
- * T.
-  *
-  * How it's used:
-  * To allow to defined the global math functions (like sin...) in certain
- * cases, like the Array expressions.
-  * When you do sin(array1+array2), the object array1+array2 has a complicated
- * expression type, all what you want to know
-  * is that it inherits ArrayBase. So we implement a partial specialization of
- * sin_impl for ArrayBase<Derived>.
-  * So we must make sure to use sin_impl<ArrayBase<Derived> > and not
- * sin_impl<Derived>, otherwise our partial specialization
-  * won't be used. How does sin know that? That's exactly what
- * global_math_functions_filtering_base tells it.
-  *
-  * How it's implemented:
-  * SFINAE in the style of enable_if. Highly susceptible of breaking compilers.
- * With GCC, it sure does work, but if you replace
-  * the typename dummy by an integer template parameter, it doesn't work
- * anymore!

-// TensorBlockAssignment assigns a block expression of type `TensorBlockExpr` to

-//
-// Currently there is no way to write from a Tensor expression to a block of
-// memory, if dimensions are reordered. If you need to do that, you should
-// materialize a Tensor block expression into a memory buffer, and then use
-// TensorBlockIO to copy data between two memory buffers with a custom
-// `target->src` dimension map (see definition above).
-//
-// Also currently the innermost dimension of `target` must have a stride '1'
-// (contiguous in memory). This restriction could be lifted with a `pscatter`,
-// but in practice it's never needed, and there is a similar TensorBlockIO
-// workaround for that.
-//
-// TODO(ezhulenev): TensorBlockAssignment is a special case of TensorBlockIO
-// where `src` is a tensor expression. Explore if it is possible to rewrite IO
-// to use expressions instead of pointers, and after that TensorBlockAssignment
-// will become an alias to IO.

-After downloading the source code of Paddle, you can build your own inference lib:
-
-```shell
-PADDLE_ROOT=./Paddle
-cd Paddle
-mkdir build
-cd build
-cmake -DPADDLE_INFERENCE_INSTALL_DIR=$PADDLE_ROOT \
-      -DCMAKE_BUILD_TYPE=Release \

-I trained a Bow model and a CNN model on IMDB dataset using the trainer. At the same time, I also trained the same models using traditional Python training methods. 
-Results show that the two methods achieve almost the same dev accuracy:

-CNN:

-I also recorded the training speed of the C++ Trainer and the python training methods, C++ trainer is quicker on CNN model:

-#TODO (mapingshuo): find the reason why C++ trainer is quicker on CNN model than python method.

Subject: [PATCH 129/486] [Paddle-TRT] add anchor generator op plugin (#31730)

* add anchor generator op plugin

* add anchor generator unit_test

* remove dbg info

* remove redundant line

* replace assertion with paddle enforce

* dynamic plugin replaces assertion with paddle enforce

* anchor generator support dynamic shape on spatial axis

* anchor generator test with fp16, dynamic shape

* add anchor generator test all

* add back main

* reduce test input size to not exceed the timelimit of ci

* change super to InferencePassTest for python2 compatibility

* reuse paddle operator anchor generator

* move creator construct to header with default

* add cuda ifdef

* reduce line

* change super to InferencePassTest for python2 compatibility

* fix anchor generator fp16 serialize setting

* split unittest from test_all

* restrict anchor generator input format before version 7234

* anchor generator only support greater than trt7.1

* change min_graph_size to 2

* min_graph size to 3 if dynamic shape

* reduce dynamic shape size to avoid trt search tactic too long to exceed time limit

* remove anchor from fetch list

* anchor generator support all trt version

* fix memory not allocated but if serialized

-merge_ids_op should be used after split_ids_op and prefetch_op, split_ids_op

-prefetch_op will send them to parameter server to prefetch embedding value

Subject: [PATCH 218/486] adds new CPU kernel for SGD op supporting BF16 data
 type (#32162)

* Initial draft for SGD BG16 kernel.

* Unit tests for SGD with BF16 data type.

* Add VLOG message to SGD BF16 op CPU kernel.

* Enhance error messages and error types.

* Refactor SGD op kernels to leverage some common code.

* Make easier to add new kerne invoke code.

* Fix SGD op kernel for sparse grad.

* Unify quotes style.

* Fix error for ROCM compilation.

* Use specialized PADDLE_ENFORCE_xx functions.

Subject: [PATCH 233/486] Update hapi to  support AMP (#31417)

* make hapi support amp, and add unittest

* make unittest only support GPU

* update parameters for amp in hapi.Model

* update hapi.Model.prepare interface, and update unittest

* fix test_model.py unittest bug

* add grad clear in dygraph

* use_fp16_guard defaults to True, which could avoid nan

* add input check, and add internal doc link to low level api

* update doc, and decrease the sample num of dataset to avoid timeout

* make hapi amp param  support str 'O1' or 'O2'

* resume calling , modify the code of the check part

* upgrade the usage of Fleet API, and disable 'pure_fp16' param

Subject: [PATCH 238/486] update `get_api_md5`, using the real api name as the
 map's key (#32224)

* get_api_md5 should prefer use the real name rather than the alias names

* case for ArgSpec style. update the unittests

+// In most cases, this map should be usable as a drop-in replacement for
+// std::unordered_map, but
+// be about 2x faster in most cases and require much less allocations.
+//
+// This implementation uses the following memory layout:
+//
+// [Node, Node, ... Node | info, info, ... infoSentinel ]
+//
+// * Node: either a DataNode that directly has the std::pair<key, val> as
+// member,
+//   or a DataNode with a pointer to std::pair<key,val>. Which DataNode
+//   representation to use
+//   depends on how fast the swap() operation is. Heuristically, this is
+//   automatically choosen
+//   based on sizeof(). there are always 2^n Nodes.
+//
+// * info: Each Node in the map has a corresponding info byte, so there are 2^n
+// info bytes.
+//   Each byte is initialized to 0, meaning the corresponding Node is empty. Set
+//   to 1 means the
+//   corresponding node contains data. Set to 2 means the corresponding Node is
+//   filled, but it
+//   actually belongs to the previous position and was pushed out because that
+//   place is already
+//   taken.
+//
+// * infoSentinel: Sentinel byte set to 1, so that iterator's ++ can stop at
+// end() without the
+//   need for a idx variable.
+//
+// According to STL, order of templates has effect on throughput. That's why
+// I've moved the
+// boolean to the front.

-## CTR READER
-
-An multi-thread cpp reader that has the same interface with py_reader. It
-uses cpp multi-thread to read file and is much more faster then the Python read
-thread in py_reader.
-
-Currently, it support two types of file:
- - gzip
- - plain text file
-
-and two types of data format:
- - cvs data format is :
-   * label dense_fea,dense_fea sparse_fea,sparse_fea
- - the svm data format is :
-   * label slot1:fea_sign slot2:fea_sign slot1:fea_sign
-
-## Distributed reader
-
-The distributed reader is mainly used by multi-process tasks, and the input must be a batch reader.
-
-Cons:
-  - It can be operated conveniently so that different processes can read different data.
-
-Pros:
-  - If batch_reader produces training data, and batch_reader loads or preprocesses data for a long time, this data reading method may be slower.

Subject: [PATCH 309/486] print the real name for Functions instead of the
 ArgSpec (#32379)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* print the real name for Functions instead of the ArgSpec

class function method

* some API's name is not __module__ + __name__

so, we disard them temporarily.

* update the logging format for console

* ommit the top level of paddle package.

* these APIs have been removed.

test=document_fix

* Another Error occerd

* print_signatures.py 's stdout is redirect to spec file, so should not print any other info.

so sad.

* print the error msg to stderr

* disable the __init__ magic method

* update unittest for sampcd_processor.py

update unittest for sampcd_processor.py

* PR-CI-APPROVAL 's python interpreter name is not 'python3'.

it's a python3.9;
it does not have paddle installed yet.

此句在CI流水线竟然不可以用。报python3找不到
此句在CI流水线竟然不可以用。因为环境没有安装paddle

* testing only extract api from __all__

paddle module(the top module) does not have __add__
test=document_fix

* should import paddle here

* update the mechanism of extractiong and executing for the sample-codes test.

更新抽取代码和执行代码的逻辑
优化输出打印

* good code style

Subject: [PATCH 338/486] Cleanup the unused codes for samplecode testing
 (#32525)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* update testcases

* remove unused codes

* update the docstring for samcd_processor

* no need to import the six module

* 我也不知道为何有一个前导空格，但现在有单元测试，取消这个空格没啥问题

* add unittests for print_signatures; add the first case for 'required' mechanism when executing sample code testing

* there is no paddle installed in PR-CI-APPROVAL

test=document_fix

Subject: [PATCH 365/486] Optimize where_index_op(prefix sum) (#30601)

* new optimize for where_index_op with prefix sum version.

* write a scan prefix sum kernel with stream for where index op.

* optimize where_index by using cub::DeviceScan::InclusiveSum instead of imperfect self-kernel.

* remove CheckTrue struct and rename stide_array for readable.

* optimize variable name for readable.

* optimize function name and annotation.

+    This spectral_norm layer applies spectral normalization to a parameter according to the 
+    following Calculation:
+
+    Step 1:
+    Generate vector U in shape of [H], and V in shape of [W].
+    While H is the :attr:`dim` th dimension of the input weights,
+    and W is the product result of remaining dimensions.
+
+    Step 2:
+    :attr:`power_iters` should be a positive integer, do following
+    calculations with U and V for :attr:`power_iters` rounds.
+
+    .. math::
+
+        \mathbf{v} := \\frac{\mathbf{W}^{T} \mathbf{u}}{\|\mathbf{W}^{T} \mathbf{u}\|_2}
+
+        \mathbf{u} := \\frac{\mathbf{W} \mathbf{v}}{\|\mathbf{W} \mathbf{v}\|_2}
+
+    Step 3:
+    Calculate :math:`\sigma(\mathbf{W})` and normalize weight values.
+
+    .. math::
+
+        \sigma(\mathbf{W}) = \mathbf{u}^{T} \mathbf{W} \mathbf{v}
+
+        \mathbf{W} = \\frac{\mathbf{W}}{\sigma(\mathbf{W})}
+
+
+    Refer to `Spectral Normalization <https://arxiv.org/abs/1802.05957>`_ .
+
+    Parameters:
+        layer(Layer): Layer of paddle, which has weight.
+        name(str, optional): Name of the weight parameter. Default: 'weight'.
+        n_power_iterations(int, optional): The number of power iterations to calculate spectral norm. Default: 1.
+        eps(float, optional): The epsilon for numerical stability in calculating norms. Default: 1e-12.
+        dim(int, optional): The index of dimension which should be permuted to the first before reshaping Input(Weight) to matrix, it should be set as 0 if Input(Weight) is the weight of fc layer, and should be set as 1 if Input(Weight) is the weight of conv layer. Default: None.

Subject: [PATCH 431/486] [Dy2stat] Fix to_tensor Bug Reported from QA (#32701)

Dy2stat failed when user writes return paddle.to_tensor(xxx), the reason is that visit_Expr doesn't work when the Expr is in return. Some other statements may trigger same bug. To fix it, we re-wrote a transformer to transform paddle.to_tensor to paddle.assign for all Call nodes.
