class PyScikitOptimize(PythonPackage):
    """Scikit-Optimize, or skopt, is a simple and efficient library to
       minimize (very) expensive and noisy black-box functions. It implements
       several methods for sequential model-based optimization. skopt aims to
       be accessible and easy to use in many contexts.

       The library is built on top of NumPy, SciPy and Scikit-Learn."""
