PyTorch implementation of

1. RNN: Recursive Neural Network from https://nlp.stanford.edu/~socherr/EMNLP2013_RNTN.pdf
   python RecursiveNN.py
   
2. TreeLSTM from https://arxiv.org/abs/1503.00075
   python TreeLSTM.py
   

add cuda as an argument to run it using cuda

Requirements:
nltk
pytorch
progressbar
