Subject: [PATCH] gnu: python-scikit-learn: Use OpenBLAS instead of ATLAS.
* gnu/packages/python.scm (python-scikit-learn)[inputs]: Replace "atlas" with
"openblas".
* gnu/packages/python.scm (python-scikit-learn)[arguments]: Remove build phase
'set-environment-variables, which is only needed when ATLAS is used.
