Installation

Prerequisites

yeti is currently only available for Linux environment. For usage in a Microsoft Windows environment, Windows Subsystem for Linux (WSL) can be used. A quick tutorial for the installation of WSL can be found here.

For a Ubuntu 20.04 distribution, the following packages are required :

  • python3

  • python3-venv

  • libpython3-dev

  • git

  • gfortran

  • gcc

  • libblas3

  • libblas-dev

  • liblapack3

  • liblapack-dev

  • cmake (minimum version 3.21 is required, a quick guide to build cmake 2.24 is available here)

Get sources

With git :

git clone https://lamcosplm.insa-lyon.fr/plugins/git/yeti/yeti.git

Create virtual python environment for yeti

Virtual environnement will be created at the root of user home directory

python3 -m venv ~/yeti-venv

To activate this environment:

source ~/yeti-venv/bin/activate

Install required python modules with pip:

pip install --upgrade pip
pip install numpy matplotlib scipy nlopt

For use of umfpack with scipy sparse solver:

pip install wheel
sudo apt install libsuitesparse-dev swig
pip install scikit-umfpack

Compile yeti

cd yeti

Create a build directory:

mkdir build
cd build

If not already loaded, load virtual python environment:

source ~/yeti-venv/bin/activate

Configure with CMake:

cmake ..

Build yeti:

make -j4

yeti library will be located in build/lib/python. You must add it to your PYTHONPATH environment variable:

export PYTHONPATH=$PYTHONPATH:~/yeti/build/lib/python
