Python Installation

Compile and install Python wrapper

Before you compile and install Python package, make sure you have done steps in C++ compile and installation.

Prerequisites

• Python: version 2.7/3.4+ is compatible miniSAM Python package.
• NumPy (pip install numpy) : Numpy is required to use miniSAM Python package.
• matplotlib (pip install matplotlib) : matplotlib is only needed to run miniSAM Python examples with visualization.

Compile and install

On Ubuntu Linux to simply compile and install the Python package:

cmake .. -DMINISAM_BUILD_PYTHON_PACKAGE=ON -DMINISAM_BUILD_SHARED_LIB=ON
make python_package
make install

After running CMake check the compile summary of the Python package:

--   Python package              Yes
--   Python version              3.5
--   Python executable           /usr/bin/python3.5

Install to Python virtualenv

If the Python package is prefer to install a virtualenv location, set the PYTHON_EXECUTABLE to the path of the Python binary, then compile and install the package.

If the virtualenv sandbox is setup at ~/test_minisam by

~$ virtualenv test_minisam

The python package can be installed to location ~/test_minisam by

cmake .. -DPYTHON_EXECUTABLE=~/test_minisam/bin/python -DMINISAM_BUILD_PYTHON_PACKAGE=ON -DMINISAM_BUILD_SHARED_LIB=ON
make python_package
make install

Verify CMake information to check the package is installed by right Python executable

--   Python package              Yes
--   Python version              2.7
--   Python executable           /home/jing/test_minisam/bin/python
