title: Determining the byte size of a scipy.sparse matrix?
body: <p>Is it possible to determine the byte size of a scipy.sparse matrix? In NumPy you can determine the size of an array by doing the following:</p>
  
  <pre><code>import numpy as np
  
  print(np.zeros((100, 100, 100).nbytes)
  8000000
  </code></pre>
