Running the baseline.py I get the error in the title. More precisely the log is the following

AttributeError: 'Predictor' object has no attribute 'model'

Indeed in line 137 of the callbacks.py there is an attempt to use self.model but call Predictor is never assigned a model in the token_evaluator function, line 200.
