NumPy is a general-purpose array-processing package designed to
|
|
efficiently manipulate large multi-dimensional arrays of arbitrary
|
|
records without sacrificing too much speed for small multi-dimensional
|
|
arrays. NumPy is built on the Numeric code base and adds features
|
|
introduced by numarray as well as an extended C-API and the ability
|
|
to create arrays of arbitrary type which also makes NumPy suitable for
|
|
interfacing with general-purpose data-base applications.
|
|
|
|
There are also basic facilities for discrete fourier transform, basic
|
|
linear algebra and random number generation.
|
|
|
|
If you need to build numpy for debugging, set DEBUG=y. If you use
|
|
software which is having problems with numpy's new relaxed strides
|
|
checking, set NPY_RSC=0.
|
|
|
|
It is highly recommended to install libraries implementing BLAS and
|
|
LAPACK before installing numpy. You may choose between:
|
|
a) blas and lapack (reference but unoptimized and thus slow)
|
|
b) OpenBLAS (optimized, provides LAPACK too)
|
|
c) atlas and lapack (optimized), good to read README.ATLAS
|
|
All these are available on SlackBuilds.org.
|
|
|
|
If you want to use the UMFPACK library instead of SuperLU to solve
|
|
unsymmetric sparse linear systems, then run this Slackbuild with
|
|
NO_UMFPACK set to "no" and then install scikit-umfpack on top of
|
|
scipy. In this context, umfpack is an optional dependency for
|
|
numpy. Nevertheless, note that presently scikit-umfpack is not
|
|
available on SlackBuilds.org.
|
|
|
|
NOTE: If you use this SlackBuild, numpy will run with the python version
|
|
provided by Slackware Linux, which is presently 2.7.xx. If
|
|
you'd like to use python 3.x then you have to install the numpy3
|
|
SlackBuild.
|
|
|
|
IMPORTANT: The version installed by this SlackBuild does NOT include the
|
|
oldnumeric and numarray compatibility modules since
|
|
starting with version 1.9.0 these modules got removed by
|
|
the numpy developers. If you need these compatibility
|
|
modules please consider the numpy-legacy SlackBuild.
|
|
THUS: This SlackBuild conflicts with the numpy-legacy
|
|
SlackBuild which installs versions < 1.9.0!
