I am trying to add an event handler to an environment that keeps track of the dual bound history.
The handler gets added as part of the BranchingDynamics reset_dynamics. When executing the code I get

Fatal Python error: PyThreadState_Get: no current thread
Python runtime state: initialized

You can find a slimmed down version of my code that produces the same error here.

I can not find an error in my approach, but maybe I am doing something wrong.
