How to Compile and Install Paddle2ONNX Locally

The compilation and installation of Paddle2ONNX require ensuring that the environment meets the following requirements:

  • cmake >= 3.16.0
  • protobuf == 21.12

1 Install on Linux/Mac

1.1 Install Protobuf

git clone https://github.com/protocolbuffers/protobuf.git
cd protobuf
git checkout v21.12
git submodule update --init
mkdir build_source && cd build_source
cmake ../cmake -DCMAKE_INSTALL_PREFIX=`pwd`/installed_protobuf_lib -Dprotobuf_BUILD_SHARED_LIBS=OFF -DCMAKE_POSITION_INDEPENDENT_CODE=ON -Dprotobuf_BUILD_TESTS=OFF -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_STANDARD=14
make -j
make install

# set the library to environment
export PATH=${PWD}/installed_protobuf_lib/bin:${PATH}

Alternatively:

Install Protobuf via apt (Linux):

sudo apt install protobuf-compiler

Install Protobuf via homebrew (Mac):

brew install protobuf

1.2 Install PaddlePaddle

python -m pip install --pre paddlepaddle -i https://www.paddlepaddle.org.cn/packages/nightly/cpu/

1.3 Install Paddle2ONNX

git clone https://github.com/PaddlePaddle/Paddle2ONNX.git
cd Paddle2ONNX
git submodule update --init
export PIP_EXTRA_INDEX_URL="https://www.paddlepaddle.org.cn/packages/nightly/cpu/"
python -m build
pip install dist/*.whl

If you are developing the Paddle2ONNX project locally, you can use pip install -e . to install it in editable mode.

2 Install on Windows

Note that the prerequisite for compiling and installing Windows is that Visual Studio 2019 is already installed in the system

2.1 Install Visual Studio 16 2019

  1. Download Visual Studio 16 2019 from this link and run vs_community.exe.
  2. Under the Workloads tab, select the checkbox for Desktop development with C++.
    • Note: Under Installation Details > Desktop Development with C++ > Optional: Live Share and Intellicode are unnecessary, feel free to uncheck these boxes.
  3. Click Install

2.2 Open Visual Studio Command Prompt

In the system menu, find x64 Native Tools Command Prompt for VS 2019 and open it.

2.3 Install Protobuf

Note that the -DCMAKE_INSTALL_PREFIX in the following cmake command specifies your actual set path.

git clone https://github.com/protocolbuffers/protobuf.git
cd protobuf
git checkout v21.12
git submodule update --init --recursive
mkdir build
cd build
cmake -G "Visual Studio 16 2019"  -DCMAKE_INSTALL_PREFIX=%CD%\protobuf_install -Dprotobuf_MSVC_STATIC_RUNTIME=OFF -Dprotobuf_BUILD_SHARED_LIBS=OFF -Dprotobuf_BUILD_TESTS=OFF -Dprotobuf_BUILD_EXAMPLES=OFF ..
cmake --build . --config Release --target install
# set the library to environment
set PATH=%CD%\protobuf_install\bin;%PATH%

2.4 Install Paddle2ONNX

git clone https://github.com/PaddlePaddle/Paddle2ONNX.git
cd Paddle2ONNX
git submodule update --init
set PIP_EXTRA_INDEX_URL=https://www.paddlepaddle.org.cn/packages/nightly/cpu/
pip install setuptools wheel auditwheel auditwheel-symbols build
python -m build
pip install dist/*.whl
