Installing from Sources

• 1. Download and Setup
• 2. Requirements
• 3. Build on Ubuntu

Download and Setup

You can download PaddlePaddle from the github source.

git clone https://github.com/baidu/Paddle paddle
cd paddle

Requirements

To compile the source code, your computer must be equipped with GCC >=4.6 or Clang compiler.

Dependencies

• CMake: version >= 2.8
• BLAS: MKL, OpenBlas or ATLAS
• protobuf: version >= 2.4, Note: 3.x is not supported
• python: only python 2.7 is supported currently

Options

PaddlePaddle supports some build options. To enable it, first you need to install the related libraries.

Optional	Description
WITH_GPU	Compile with GPU mode.
WITH_DOUBLE	Compile with double precision floating-point, default: single precision.
WITH_GLOG	Compile with glog. If not found, default: an internal log implementation.
WITH_GFLAGS	Compile with gflags. If not found, default: an internal flag implementation.
WITH_TESTING	Compile with gtest for PaddlePaddle's unit testing.
WITH_DOC	Compile to generate PaddlePaddle's docs, default: disabled (OFF).
WITH_SWIG_PY	Compile with python predict API, default: disabled (OFF).
WITH_STYLE_CHECK	Compile with code style check, default: enabled (ON).

Note:

• The GPU version works best with Cuda Toolkit 7.5 and cuDNN v5.
• Other versions like Cuda Toolkit 6.5, 7.0, 8.0 and cuDNN v2, v3, v4 are also supported.
• To utilize cuDNN v5, Cuda Toolkit 7.5 is prerequisite and vice versa.

As a simple example, consider the following:

1. Python Dependencies(optional)

   To compile PaddlePaddle with python predict API, make sure swig installed and set -DWITH_SWIG_PY=ON as follows:

   # install swig on ubuntu
   sudo apt-get install swig
   # install swig on Mac OS X
   brew install swig
   
   # active swig in cmake
   cmake .. -DWITH_SWIG_PY=ON
   

2. Doc Dependencies(optional)

   To generate PaddlePaddle’s documentation, install dependencies and set -DWITH_DOC=ON as follows:

   pip install 'sphinx>=1.4.0'
   pip install sphinx_rtd_theme breathe recommonmark
   
   # install doxygen on Ubuntu
   sudo apt-get install doxygen 
   # install doxygen on Mac OS X
   brew install doxygen
   
   # active docs in cmake
   cmake .. -DWITH_DOC=ON`
   

Build on Ubuntu 14.04

Install Dependencies

• CPU Dependencies

  # necessary
  sudo apt-get update
  sudo apt-get install -y g++ make cmake build-essential libatlas-base-dev python python-pip libpython-dev m4 libprotobuf-dev protobuf-compiler python-protobuf python-numpy git
  # optional
  sudo apt-get install libgoogle-glog-dev
  sudo apt-get install libgflags-dev
  sudo apt-get install libgtest-dev
  sudo pip install wheel
  pushd /usr/src/gtest
  cmake .
  make
  sudo cp *.a /usr/lib
  popd
  

• GPU Dependencies (optional)

  To build GPU version, you will need the following installed:

    1. a CUDA-capable GPU
    2. A supported version of Linux with a gcc compiler and toolchain
    3. NVIDIA CUDA Toolkit (available at http://developer.nvidia.com/cuda-downloads)
    4. NVIDIA cuDNN Library (availabel at https://developer.nvidia.com/cudnn)
  

  The CUDA development environment relies on tight integration with the host development environment, including the host compiler and C runtime libraries, and is therefore only supported on distribution versions that have been qualified for this CUDA Toolkit release.

  After downloading cuDNN library, issue the following commands:

  sudo tar -xzf cudnn-7.5-linux-x64-v5.1.tgz -C /usr/local
  sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*
  

  Then you need to set LD_LIBRARY_PATH, PATH environment variables in ~/.bashrc.

  export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
  export PATH=/usr/local/cuda/bin:$PATH
  

Build and Install

As usual, the best option is to create build folder under paddle project directory.

mkdir build && cd build
cmake ..

CMake first check PaddlePaddle’s dependencies in system default path. After installing some optional libraries, corresponding build option will be set automatically (for instance, glog, gtest and gflags). If still not found, you can manually set it based on CMake error information from your screen.

As a simple example, consider the following:

• Only CPU

  cmake  .. -DWITH_GPU=OFF
  

• GPU

  cmake .. -DWITH_GPU=ON
  

• GPU with doc and swig

  cmake .. -DWITH_GPU=ON -DWITH_DOC=ON -DWITH_SWIG_PY=ON
  

Finally, you can build PaddlePaddle:

# you can add build option here, such as:    
cmake .. -DWITH_GPU=ON -DCMAKE_INSTALL_PREFIX=<path to install>
# please use sudo make install, if you want to install PaddlePaddle into the system
make -j `nproc` && make install
# set PaddlePaddle installation path in ~/.bashrc
export PATH=<path to install>/bin:$PATH

Note:

If you set WITH_SWIG_PY=ON, related python dependencies also need to be installed. Otherwise, PaddlePaddle will automatically install python dependencies at first time when user run paddle commands, such as paddle version, paddle train. It may require sudo privileges:

# you can run
sudo pip install <path to install>/opt/paddle/share/wheels/*.whl
# or just run 
sudo paddle version
