NameError: name 't_class' is not defined

Hello

first of all thank you for implementing this paper.
Everything of your code run without an error.
But if I want to run the last file "python Training_Fine_Classification.py"
I got the following error:

Training_Fine_Classification.py 
training.txt
Traceback (most recent call last):
  File "Training_Fine_Classification.py", line 175, in <module>
    print(t_class)
NameError: name 't_class' is not defined

In this file are many lines which are commented out, so I tried to uncomment them and got the following error after I fix the wrong Indentation:
Traceback (most recent call last): File "Training_Fine_Classification.py", line 147, in <module> X=hstack((X_words,X_POS)) File "/home/nicolas/Desktop/ML/brmson/ENV/local/lib/python2.7/site-packages/scipy/sparse/construct.py", line 458, in hstack return bmat([blocks], format=format, dtype=dtype) File "/home/nicolas/Desktop/ML/brmson/ENV/local/lib/python2.7/site-packages/scipy/sparse/construct.py", line 579, in bmat raise ValueError(msg) ValueError: blocks[0,:] has incompatible row dimensions. Got blocks[0,1].shape[0] == 11, expected 1.

It would be nice if you could help me on this and if you could write a bit more on the Readme, what every file does and if the results of the paper could be reached.

Regards
Nic
