This is the Python package implementation of the GPBoost library. See https://github.com/fabsig/GPBoost for more information on the modeling background and the software implementation.

• Examples and documentation
• Installation
  • Installation from PyPI
  • Installation from source

• Python examples
  • GPBoost / LaGaBoost algorithm for Gaussian ("regression") and non-Gaussian likelihoods (e.g., "classification", etc.)
  • Generalized linear Gaussian process and mixed effects models
• The documentation at https://gpboost.readthedocs.io

• setuptools is needed. You can install this using pip install setuptools -U

• 32-bit Python is not supported. Please install the 64-bit version. See build 32-bit version with 32-bit Python section.

pip install gpboost -U

• For Windows users, VC runtime is needed if Visual Studio (2015 or newer) is not installed.

• For Linux users, glibc >= 2.14 is required.

  • If you get an error message version `GLIBC_2.27' not found, you need to install from source.

  • In rare cases, when you get the OSError: libgomp.so.1: cannot open shared object file: No such file or directory error when importing GPBoost, you need to install the OpenMP runtime library separately (use your package manager and search for lib[g|i]omp for doing this).

• For macOS users:

  • The library file in distribution wheels is built by the Apple Clang compiler. You need to install the OpenMP library. You can install the OpenMP library by the following command: brew install libomp.

  • If you have an arm64 Apple silicon processor (e.g., M1 or M2) and experience problems, try the following steps:

    • uninstall homebrew (in case you have migrated from an older non-arm64 Mac)
    • install homebrew (to make sure that you have an arm64 version of libomp)
    • install OpenMP (brew install libomp)
    • remove existing python environments and install Miniforge (brew install miniforge and conda init "$(basename "${SHELL}")")

Installation from source can be either done from PyPI or GitHub.

• Installation from source requires that you have installed CMake.

• For Linux users, glibc >= 2.14 is required.

  • In rare cases, you may need to install the OpenMP runtime library separately (use your package manager and search for lib[g|i]omp for doing this).

• For macOS users, you can perform installation either with Apple Clang or gcc.

  • In case you prefer Apple Clang, you should install OpenMP (details for installation can be found in the Installation Guide) first and CMake version 3.16 or higher is required. Only Apple Clang version 8.1 or higher is supported.

  • In case you prefer gcc, you need to install it (details for installation can be found in the Installation Guide) and specify compilers by running export CXX=g++-7 CC=gcc-7 (replace "7" with the version of gcc installed on your machine) first.

• For Windows users, Visual Studio (or VS Build Tools) is needed.

pip install --no-binary :all: gpboost

pip install gpboost --install-option=--mingw

• CMake and MinGW-w64 should be installed first.

git clone --recursive https://github.com/fabsig/GPBoost.git
cd GPBoost/python-package
# export CXX=g++-7 CC=gcc-7  # macOS users, if you decided to compile with gcc, don't forget to specify compilers (replace "7" with version of gcc installed on your machine)
python -m pip install .

• CMake and MinGW-w64 should be installed first.

python setup.py install --mingw

python setup.py install --cudagp

For macOS and Windows users, the CUDA version is not supported.

CUDA library is needed: details for installation can be found in Installation Guide.
