buildtools

We release PaddlePaddle and PaddlePaddle Fluid as shared libraries, which, we hope could be released as wheel packages on PyPI, so we need to make sure that the build follows the manulinux1 standard.

The manylinux standard suggests building Python modules on an old system, because that a module would anyway depend on some shared libraries, and Linux's shared library standard states that those built with newer version compilers cannot work with those with older versions. The suggested building environment is as old as CentOS 5. However, PaddlePaddle relies on CUDA, and the earlies version of CentOS works with CUDA is 6. So, here we provide a Docker image based on CentOS 6 and CUDA for building PaddlePaddle and making the release supports "as-manylinux as possible." or "sufficiently many Linux" according to this discussion.

The build output of our Docker image includes multiple wheel files -- some contain the CPU-only binary, some others support CUDA; some are compatible with the cp27m Python ABI, some others with cp27.

To build these wheels, please run the following commands:

git clone https://github.com/paddlepaddle/paddle
cd paddle/tools/manylinux1
REPO=[yourrepo] ./build_all.sh

Build PaddlePaddle for the different Python ABIs

Choose one of the following Python ABI and set the correct environment variables.

• cp27-cp27m

  export LD_LIBRARY_PATH=/opt/_internal/cpython-2.7.11-ucs2/lib:${LD_LIBRARY_PATH#/opt/_internal/cpython-2.7.11-ucs4/lib:}
  export PATH=/opt/python/cp27-cp27m/bin/:${PATH}
  export PYTHON_FLAGS="-DPYTHON_EXECUTABLE:FILEPATH=/opt/python/cp27-cp27m/bin/python
        -DPYTHON_INCLUDE_DIR:PATH=/opt/python/cp27-cp27m/include/python2.7
        -DPYTHON_LIBRARIES:FILEPATH=/opt/_internal/cpython-2.7.11-ucs2/lib/libpython2.7.so"
  

• cp27-cp27mu

  export LD_LIBRARY_PATH=/opt/_internal/cpython-2.7.11-ucs4/lib:${LD_LIBRARY_PATH#/opt/_internal/cpython-2.7.11-ucs2/lib:}
  export PATH=/opt/python/cp27-cp27mu/bin/:${PATH}
  export PYTHON_FLAGS="-DPYTHON_EXECUTABLE:FILEPATH=/opt/python/cp27-cp27mu/bin/python
        -DPYTHON_INCLUDE_DIR:PATH=/opt/python/cp27-cp27mu/include/python2.7
        -DPYTHON_LIBRARIES:FILEPATH=/opt/_internal/cpython-2.7.11-ucs4/lib/libpython2.7.so"
  

And then add the PYTHON_FLAGS as your cmake flags:

cmake ..
  ${PYTHON_FLAGS} \
  -DWITH_GPU=OFF \
  ...
