title: How to just print numpy 2d array in Python 3?
body: <p>I'm new in Python 3.</p>
  
  <p>My code is following, and I don't know how to solve this problem.</p>
  
  <pre><code>test = np.random.randn(10)
  print (test)
  
  TypeError: '&gt;' not supported between instances of 'int' and 'str'
  </code></pre>
  
  <p>(+)
  I already imported numpy, and detailed error msg is following.</p>
