    This exception indicate that runner (object of :class:`grid2op.Runner.Runner`) has already been used.

    This behaviour is not supported on windows / macos given the way the Multiprocessing package works (spawning
    a process where grid2op objects are made is not completly supported at the moment).

    The best solution is to recreate a runner, and then use this new one.
