title: How to read a numpy ndarray from a block of memory?
body: <p>I have a block of memory that stores a 2D array of <code>float32</code> numbers.</p>
  
  <p>For example, the shape is <code>(1000, 10)</code>, and what I have in memory is something like a C array with <code>10000</code> elements.</p>
  
  <p>Can I turn this into a numpy array just by specifying the shape and <code>dtype</code>?</p>
