  This paper introduces pyRecLab, a software library written in C++ with Python
bindings which allows to quickly train, test and develop recommender systems.
Although there are several software libraries for this purpose, only a few let
developers to get quickly started with the most traditional methods, permitting
them to try different parameters and approach several tasks without a
significant loss of performance. Among the few libraries that have all these
features, they are available in languages such as Java, Scala or C#, what is a
disadvantage for less experienced programmers more used to the popular Python
programming language. In this article we introduce details of pyRecLab, showing
as well performance analysis in terms of error metrics (MAE and RMSE) and
train/test time. We benchmark it against the popular Java-based library LibRec,
showing similar results. We expect programmers with little experience and
people interested in quickly prototyping recommender systems to be benefited
from pyRecLab.
