Abstract

\(\mathsf {Safe PILCO}\) is a software tool for safe and data-efficient policy search with reinforcement learning. It extends the known \(\mathsf {PILCO}\) algorithm, originally written in MATLAB, to support safe learning. \(\mathsf {Safe PILCO}\) is a Python implementation and leverages existing libraries that allow the codebase to remain short and modular, towards wider use by the verification, reinforcement learning, and control communities.

  1. 1.

  4. 4.

    By way of comparison, all gradient calculations in the \(\mathsf {PILCO}\) Matlab implementation are hand-coded, thus extensions are laborious as any additional user-defined controller or reward function has to include these gradient calculations too.
