Python Module
FAST has also support for Python. The module, called pyFAST, works with python 3 only. The Python wrapper is generated using SWIG.
pyFAST can be installed using pip as follows, note however that you must have all the requirements installed for the package to work. pip install pyfast
Building the Python wrappers
The Python wrapper is a separate module which have to be enabled with the FAST_MODULE_Python CMake flag.
Windows
Download Python 3 64 bit.
Linux/Ubuntu
You also need python libs installed. sudo apt-get install libpython3-dev # Python 3
Building
The python module is integrated with numpy, thus requiring numpy to be installed:
# For linux only: pip install pylddwrap
Make sure you have built the entire FAST framework first: cmake --build . --config Release -j8
You may then build the target named _fast, which will build the FAST python bindings.
Building the Python wheel package
Building the target named python-wheel will create a python package, also a called a wheel in the folder build_folder/python/dist/ cmake --build . --config Release -j8 --target python-wheel
You can upload this package to pypi using twine:
twine upload -r testpypi pyFAST-xxxx.whl # For test pypi twine upload pyFAST-xxxx.whl # For pypi
Troubleshoot
If you get several link errors like: "error LNK2019: unresolved external symbol __imp_PyType_IsSubtype referenced in function ...". Make sure you have downloaded the 64 bit version of python (see https:/
On windows the Python paths in CMake may have to be set manually:
PYTHON_LIBRARY="C:\Python38\libs\python38.lib" PYTHON_INCLUDE_DIR="C:\Python38\include"
