Show libraries in the system on which NumPy was built.

|
|
Print information about various resources (libraries, library

directories, include directories, etc.) in the system on which
|
|
NumPy was built.

Notes
|
|
-----
|
|
1. Classes specifying the information to be printed are defined
|
|
in the `numpy.distutils.system_info` module.
|
|
|
|
Information may include:
|
|
|
|
* ``language``: language used to write the libraries (mostly
|
|
C or f77)
|
|
* ``libraries``: names of libraries found in the system
|
|
* ``library_dirs``: directories containing the libraries
|
|
* ``include_dirs``: directories containing library header files
|
|
* ``src_dirs``: directories containing library source files
|
|
* ``define_macros``: preprocessor macros used by
|
|
``distutils.setup``
|
|
* ``baseline``: minimum CPU features required
|
|
* ``found``: dispatched features supported in the system
|
|
* ``not found``: dispatched features that are not supported
|
|
in the system

2. NumPy BLAS/LAPACK Installation Notes
|
|
|
|
Installing a numpy wheel (``pip install numpy`` or force it
|
|
via ``pip install numpy --only-binary :numpy: numpy``) includes
|
|
an OpenBLAS implementation of the BLAS and LAPACK linear algebra
|
|
APIs. In this case, ``library_dirs`` reports the original build
|
|
time configuration as compiled with gcc/gfortran; at run time
|
|
the OpenBLAS library is in
|
|
``site-packages/numpy.libs/`` (linux), or
|
|
``site-packages/numpy/.dylibs/`` (macOS), or
|
|
``site-packages/numpy/.libs/`` (windows).
|
|
|
|
Installing numpy from source
|
|
(``pip install numpy --no-binary numpy``) searches for BLAS and
|
|
LAPACK dynamic link libraries at build time as influenced by
|
|
environment variables NPY_BLAS_LIBS, NPY_CBLAS_LIBS, and
|
|
NPY_LAPACK_LIBS; or NPY_BLAS_ORDER and NPY_LAPACK_ORDER;
|
|
or the optional file ``~/.numpy-site.cfg``.
|
|
NumPy remembers those locations and expects to load the same
|
|
libraries at run-time.
|
|
In NumPy 1.21+ on macOS, 'accelerate' (Apple's Accelerate BLAS
|
|
library) is in the default build-time search order after
|
|
'openblas'.

|
