Undefined variable

Dear Jshermeyer,
Thank for your hard working.
I have a question in 320th line:
Train_TrainSet, Train_TestSet, Target_TrainSet, Target_TestSet = train_test_split(Trains[0], Targets[0], test_size=0.1, train_size=0.1)
'Trains' and 'Targets' are not defined,Is this program unnecessary?

Yes I think this is actually a redundancy I forgot to remove. Uploaded the updated code with this removed to master.
