Problem with QuadCostFactory

[moowees]

Hello,
i have a problem running the example 4_Factories_and_Pipelines.
Each time i run the following code, my notebook crashes.

from autompc.costs import QuadCostFactory
cost_factory = QuadCostFactory(system)
cost_cfg = cost_factory.get_configuration_space().get_default_configuration()
cost = cost_factory(cost_cfg, task, trajs)

Do you have a solution for this issue?

Best Regards
