So a scipy-0.17.1-intel-2016b-Python-2.7.12.eb should not be needed, since the Python module Python-2.7.12-intel-2016b.eb has scipy 0.17.1 in its extension list? Indeed. And when scipy 0.18.0 is released, we can install it without touching the existing Python 2.7.12 installation. So the only think popping up to me is the mpi4py, if a user needs a 2.0.0 instead of the 1.3.1 inside the Python config. But in general this should not be a performance issue like e.g. compile netlib blas vs MKL. Correct? Indeed, the intention there is to install that mpi4py as a standalone module, on top of the existing Python 2.7.12 installation. Via $PYTHONPATH, the mpi4py 2.0.0 installation will have preference if the module is loaded. Knowing this earlier might have saved me some time. But it will now into the future. Should we sort of retire (that is remove) things like SciPy from the eb-configs? The current policy is to not remove existing easyconfig files we included in the central repository. That is, until we will deprecate a bunch of old toolchains (more on that later). Hmm, but is there a way to document (or for me to pick up easily) that most users should not have the need to build numpy/scipy modules, since reasonably up-to-date performance versions are included in the EB python builds? From eb -S so far I didn’t quit get this.

Why are the separate easyconfigs for those kind of packages as well? Are the later obsolete? Someone minds clueing me? The current policy is to include 'extensions' in the main easyconfig if they don't require extra dependencies. If they need additional deps, we create a separate easyconfig. The reason that there something are separate easyconfigs for mpi4py and such is if we need a newer or older version then included in the main easyconfig. Ward
