Compile Shogun 6.1.3 with Miniconda.
It just happened to me to have to compile the Python interface of Shogun 6.1.3 by using Miniconda as Python environment. I will report here the steps needed to do it just in case somebody else needs it (or in case I’ll need them again in a not so far away future).
Everything was done on a Debian GNU/Linux 9 machine. My
is the 4.5.11.
Since I wanted to use Python 3.5, I needed to create a new conda environment. Then I needed to activate it in order to be able to use it correctly:
conda create -n python3.5 python=3.5 source activate python3.5
Remember that all the instructions below will work only when inside the new conda environment. In fact, this will enable Shogun only for Python 3.5.
Secondly, we have to download and extract the packages (both the toolbox and gpl code):
wget https://github.com/shogun-toolbox/shogun/archive/shogun_6.1.3.tar.gz wget https://github.com/shogun-toolbox/shogun-gpl/archive/v6.1.3.tar.gz tar -xvf shogun_6.1.3.tar.gz -C shogun_6_1_3 tar -xvf v6.1.3.tar.gz -c shogun_6_1_3/src/gpl
Then, we have to build the toolbox (here
$MINICONDADIR indicates the directory
where you installed miniconda). The build process will leave out the
test suite, the meta examples and it will compile Shogun in release mode.
It will also install Shogun in a custom directory in a way to avoid using
cd shogun_6_1_3/ mkdir build/ cd build/ cmake -DCMAKE_INSTALL_PREFIX=/path/to/shogun/install/dir \ -DPYTHON_INCLUDE_DIR=$MINICONDADIR/envs/python3.5/include/python3.5m \ -DPYTHON_LIBRARY=$MINICONDADIR/envs/python3.5/lib/libpython3.5m.so \ -DPYTHON_EXECUTABLE:FILEPATH=$MINICONDADIR/envs/python3.5/bin/python \ -DPYTHON_PACKAGES_PATH=$MINICONDADIR/envs/python3.5/lib/python3.5 \ -DINTERFACE_PYTHON=ON \ -DBUILD_META_EXAMPLES=OFF \ -DENABLE_TESTING=OFF \ -DCMAKE_BUILD_TYPE=Release ../ make install
Remember to add the following lines to your
.bashrc file in order
to set the library and interface locations:
export LD_LIBRARY_PATH="/path/to/shogun/install/dir/lib:$LD_LIBRARY_PATH" export PYTHONPATH="/path/to/shogun/install/dir/lib/python3.5/site-packages/shogun.py:$PYTHONPATH"
Ff you reached this point without errors then you are done! You should be able to access Shogun 6.1.3 from your conda’s environment.
