class PyNumpyGroupies(PythonPackage):
"""This package consists of a couple of optimised tools for doing things
that can roughly be considered "group-indexing operations". The most
prominent tool is `aggregate`. `aggregate` takes an array of values, and
an array giving the group number for each of those values. It then returns
the sum (or mean, or std, or any, ...etc.) of the values in each group.
You have probably come across this idea before, using `matlab` accumarray,
`pandas` groupby, or generally MapReduce algorithms and histograms. There
are different implementations of `aggregate` provided, based on plain
`numpy`, `numba` and `weave`. Performance is a main concern, and so far we
comfortably beat similar implementations in other packages (check the
benchmarks)."""
