8 years ago Ok figured out the problem. I believe the NeuralModels have been updated since you probably downloaded it.
The updates argument in theano.function() expects list of pairs (tuples) but the rmsprop update step (self.updates = update_type.get_updates(self.params,self.cost)) is adding some other list that's creating some problem.
So I only sublist the obtained self.updates by doing: self.updates = self.updates[0] before passing it into the theano.function()
Then, everything works.
I tried to run the simulation using the 'all' maneuver-type, fold_1. I modified the maneuver-rnn.py so it takes in maneuver-type rather than index argument. I'm getting an error during the execution of MultipleRNNsCombined. It says too many values to unpack. Any thoughts on what might be the problem.
