How do I run your code? I downloaded it from your github repository but running python main.py gives:
(py27) [rzou@devgpu226.prn2 ~/deep-q-learning] python main.py
Loading Memory data into Replay Memory Instance...
Traceback (most recent call last):

  File "/home/rzou/deep-q-learning/utils/models.py", line 28, in __init__
    self.load()
