Subject: [PATCH] Replace ATLAS with OpenBLAS (+lapack)
Date: Fri, 12 Jun 2015 11:41:40 +0200 [thread overview]
Message-ID: <idjioat2rhn.fsf@bimsb-sys02.mdc-berlin.net> (raw)
[-- Attachment #1: Type: text/plain, Size: 436 bytes --]
Hi Guix,
attached are three more patches to replace ATLAS with OpenBLAS in
python.scm.
I noticed that numpy also needs "lapack", because OpenBLAS is built with
"NO_LAPACK=1". That's what the first patch is for.
This is also important for the second patch which makes python-scipy use
OpenBLAS and Lapack instead of ATLAS.
The final patch replaces "atlas" with "openblas" in the
python-scikit-learn package definition.

Subject: [PATCH 1/3] gnu: python-numpy-bootstrap: Add lapack to inputs.
* gnu/packages/python.scm (python-numpy-bootstrap)[inputs]: Add lapack to
inputs, because OpenBLAS does not include lapack functions.
