Python wrappers to the C++ library SymEngine, a fast C++ symbolic manipulation library.
See License section for information about wheels
pip install symengine --user
conda install python-symengine -c symengine -c conda-forge
optionally, you may choose to install an early developer preview:
conda install python-symengine -c symengine/label/dev -c conda-forge
Install prerequisites.
CMake >= 2.8.12
Python3 >= 3.7
Cython >= 0.29.24
SymEngine >= 0.7.0
For SymEngine, only a specific commit/tag (see symengine_version.txt) is supported. Latest git master branch may not work as there may be breaking changes in SymEngine.
Python wrappers can be installed by,
python setup.py install
Additional options to setup.py are
python setup.py install build_ext
--symengine-dir=/path/to/symengine/install/dir # Path to SymEngine install directory or build directory
--compiler=mingw32|msvc|cygwin # Select the compiler for Windows
--generator=cmake-generator # CMake Generator
--build-type=Release|Debug # Set build-type for multi-configuration generators like MSVC
--define="var1=value1;var2=value2" # Give options to CMake
--inplace # Build the extension in source tree
Standard options to setup.py like --user
, --prefix
can be used to
configure install location. NumPy is used if found by default, if you wish
to make your choice of NumPy use explicit: then add
e.g. WITH_NUMPY=False
to --define
.
Use SymEngine from Python as follows:
>>> from symengine import var
>>> var("x y z")
(x, y, z)
>>> e = (x+y+z)**2
>>> e.expand()
2*x*y + 2*x*z + 2*y*z + x**2 + y**2 + z**2
You can read Python tests in symengine/tests
to see what features are
implemented.
