Proposed change(s)
In the current form, the DefaultTrainerDict can't be deserialized from pickle (and thus can't be passed to a worker process from the subprocess module, which I'm trying to do in #4780). It appears that the initializer needs to be able to take both forms of arguments; I'm not sure if there's a cleaner way to do this.
