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. + +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 which + is available for python2 only and does not conflict with this + installation of numpy. + |
