title: Numpy: creating an empty array results in memory error?
body: <p>I need to store a ton of information in a numpy array.  It needs to be of the following shape:</p>
  
  <pre><code>facefeature1s = np.empty([2000,64,64,64,32])
  </code></pre>
  
  <p>When I run this, i get a memory error.  What can I do about this?  </p>
  
  <p>Error is:</p>
  
  <pre><code>    MemoryError                               Traceback (most recent call last)
  &lt;ipython-input-271-2c56a37b4a7c&gt; in &lt;module&gt;()
  ----&gt; 1 facefeature1s = np.empty([2000,64,64,64,32])
  </code></pre>
