Abstract
We present updates on the development of $\mathrm{pyS{\scriptsize{}EC}D{\scriptsize{}EC}}$, a toolbox to numerically evaluate pa-
rameter integrals in the context of dimensional regularization. We discuss difficulties with loop
integrals in the special kinematic condition where the squared momentum of a leg is equal to the
squared mass of a propagator. We further discuss some features of a Quasi Monte Carlo (QMC)
integrator that can optionally run on Graphics Processing Units (GPUs).
