A series of function written in Cython that speed up critical functions to improve the overall performance of the Brightway2 life cycle assessment framework.
In order to avoid having to have Cython as a dependency, this library includes both the pyx and Cython-generated c code, and is distributed as pre-compiled wheels, except on Linux where access to a C compiler is assumed.
cython -t bw2speedups/_consolidate.pyx bw2speedups/_indexer.pyx bw2speedups/_find_first.pyx
Although you can do this inplace, in my experience it is easier to just install the library in a temporary environment. You don't want to deal with .so files in the source repository.
Install the library into a temporary environment, then manually run the separate test files, i.e. python bw2speedupds/test/test_consolidate.py. This isn't the most elegant, but it will do for now.
pip install wheel
python setup.py bdist_wheel
Note that this has to be done separately for each OS and environment, i.e. Windows 32-bit and 64-bit versions of Python are separate wheels, even with the same version of Windows.
