算能RISC-V通用云编译飞桨paddlepaddle@openKylin留档

尝试一在riscv里编译飞桨。

先总结：

下载飞桨代码，参照pr修改代码

然后编译

cmake ../ -DWITH_GPU=OFF -DWITH_RISCV=ON
make -j 16 TARGET=RISCV64_GENERIC

编译好后安装：

pip install paddlepaddle-0.0.0-cp38-cp38-linux_riscv64.whl -i https://mirror.baidu.com/pypi/simple

先git下载源码

git clone https://github.com/paddlepaddle/padle

配置环境

pip3 install protobuf

还有一些库等，具体可以参考编译pytorch的文档：算能RISC-V通用云开发空间编译pytorch @openKylin留档-CSDN博客

然后进入paddle目录编译

mkdir build

cd build

cmake ../

我的天，除了protobuf，竟然一下子编译完成了！

Automatic code generation for paddle/fluid/primitive succeed.
Automatic code generation for decomp interface succeed.
WITH_DLNNE:
-- Configuring done
-- Generating done
-- Build files have been written to: /root/github/paddle/build

是我肤浅了，后面还需要编译呢root@863c89a419ec:~/github/paddle/build# make

make -j 16

make -j 8 TARGET=RISCV64_GENERIC -dw

如果碰到报错，根据报错进行处理，比如哪个第三方库编译失败，就删除那个目录，然后在third_party目录执行：git submodule update --init --recursive

然后再make 即可。

困了，让它编译去吧。

报错了

通过官网issue，发现cmake指令为：

cmake ../ -DWITH_GPU=OFF -WITH_RISCV=ON

make 指令为;

make -j 16 TARGET=RISCV64_GENERIC

发现cmake指令有问题

拼写错误，应该是：

cmake ../ -DWITH_GPU=OFF -DWITH_RISCV=ON

然后再make

看MakeFile文件里面没有RISCV选项，不知道是不是cmake编译器那边支持，先执行看看。（后来知道，人家这个RISCV是对应了专门的pr的，目前这个pr还没有合并，所以需要手工改密码）

cmake结束之后提示WITH_RISCV没有生效

手工添加飞桨对riscv的支持

修改CMakeFile文件，在WITH_ARM的后面加上：

if(WITH_RISCV)
  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fPIC")
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC")
  set(WITH_XBYAK
      OFF
      CACHE STRING "Disable XBYAK when compiling WITH_RISCV=ON." FORCE)
  set(WITH_MKL
      OFF
      CACHE STRING "Disable MKL when compiling WITH_RISCV=ON." FORCE)
  set(WITH_AVX
      OFF
      CACHE STRING "Disable AVX when compiling WITH_AVX=OFF." FORCE)
  add_definitions(-DPADDLE_WITH_RISCV)
endif()

修改文件：cmake/flags.cmake

在ARM后面加上：AND NOT WITH_RISCV

同时找到了-m64的位置。因为加了这句，就不用手工删除-m64这句。

修改文件：paddle/fluid/operators/search_compute.h

一共需要修改四处，在四处加上defined(PADDLE_WITH_RISCV)：

33行if那句后面加上RISCV，变成这样：

    !defined(PADDLE_WITH_SW) && !defined(PADDLE_WITH_MIPS) &&        \

#include <cpuid.h>
inline void cpuid(int reg[4], int x) {

感觉离曙光很近了。

重新cmake和make，希望不会碰到“pmmintrin.h”文件找不到的错误。

发现少修改一个文件

修改文件cmake/third_party.cmake

if(WITH_POCKETFFT)
  include(external/pocketfft)
  list(APPEND third_party_deps extern_pocketfft)
  add_definitions(-DPADDLE_WITH_POCKETFFT)

  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-maybe-uninitialized") # Warnings in pocketfft_hdronly.h
endif()
endif()

11点开始编译，计时开始！15：37分编译完成，耗时4小时37分钟！

哈哈，它静静的躺在那里：

安装：

安装后执行import paddle 报错。

总结：

目前已编译成功。

目前import paddle报错。

调试

报错：Could NOT find PY_google.protobuf (missing: PY_GOOGLE.PROTOBUF)

Could NOT find PY_google.protobuf (missing: PY_GOOGLE.PROTOBUF)

安装protobuf

pip3 install protobuf

编译时到100%报错

如何在RISC-V平台编译paddle - 知乎

在paddle/build/third_party删除eigen3目录，然后执行：git submodule update --init --recursive

问题解决。

问题没有解决，还是4%这里报错：

重新设置make 后，cmake ../ -DWITH_GPU=OFF -WITH_RISCV=ON 编译报错

报错c++: error: unrecognized command line option '-m64'

按照文档，应该“查找makefile文件的生成逻辑，最终发现在Paddle.cmake文件中有这样一段逻辑”，将该文件中的-64去掉。

但是没有找到这个文件。找到了，在这里：

cmake/flags.cmake

if(NOT WITH_NV_JETSON
     AND NOT WITH_ARM
     AND NOT WITH_RISCV
     AND NOT WITH_SW
     AND NOT WITH_MIPS
     AND NOT WITH_LOONGARCH)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -m64")
endif()

后期通过修改源码，添加RISCV选项的方法，使代码支持RISCV，并同时使用-m64失效

在cmake的时候加上DWITH_RISCV提示没有生效

WITH_DLNNE:
-- Configuring done
-- Generating done
CMake Warning:
Manually-specified variables were not used by the project:

WITH_RISCV

按照飞桨官网pr，修改飞桨make相关文件。

编译报错没有 pmmintrin.h文件

这个对应的就是paddle/fluid/platform/denormal.cc 这个文件，已经修改。

看文档，有人说是patchelf版本低的缘故，升级patchelf，再重新编译，问题依旧
