title: increasing NumPy memory limit
body: <p>I am currently doing coding some NN for huge dataset, for example MNIST dataset (about 700*50000). But when I test it, my code got MemoryError. I have a computer with 12 GB ram, but I think Python or Numpy can't use all of them. </p>
  
  <p>Can I push Python or Numpy to use all remaining available memory in my PC ?</p>
  
  <p>OS : Windows 7 64-bit</p>
  
  <p>Python : Python(x, y) 2.7.60</p>
  
  <p>Thanks</p>
