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/PaddlePaddle/Paddle paddle
cd paddle

Requirements

To compile the source code, your computer must be equipped with the following dependencies.

Compiler: GCC >= 4.8 or Clang >= 3.3 (AppleClang >= 5.1)
CMake: version >= 3.0 (at least CMake 3.4 on Mac OS X)
BLAS: MKL, OpenBlas or ATLAS

Note: For CUDA 7.0 and CUDA 7.5, GCC 5.0 and up are not supported! For CUDA 8.0, GCC versions later than 5.3 are not supported!

Options

PaddlePaddle supports some build options.

ON_COVERALLS	Compile PaddlePaddle with code coverage
COVERALLS_UPLOAD	Package code coverage data to coveralls
ON_TRAVIS	Exclude special unit test on Travis CI

</html>

Note:

The GPU version works best with Cuda Toolkit 8.0 and cuDNN v5.
Other versions like Cuda Toolkit 7.0, 7.5 and cuDNN 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:

BLAS Dependencies(optional)

Paddle will find BLAS from system's default path. But you can specify MKL, OpenBLAS or ATLAS via MKL_ROOT, OPENBLAS_ROOT or ATLAS_ROOT.
```
# specify MKL
cmake .. -DMKL_ROOT=<mkl_path>
# or specify OpenBLAS
cmake .. -DOPENBLAS_ROOT=<openblas_path>
```

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 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 git
sudo pip install wheel numpy
sudo pip install 'protobuf>=3.0.0'

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

Finally, you can build and install PaddlePaddle:

# you can add build option here, such as:    
cmake .. -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
# install PaddlePaddle Python modules.
sudo pip install <path to install>/opt/paddle/share/wheels/*.whl
