title: How to convert a numpy matrix to a pandas series?
body: <p>I have the following numpy matrix:</p>
  
  <pre><code>array([[64, 22,],
     [58, 64],
     [42, 31])
  </code></pre>
  
  <p>And i want to get the following:</p>
  
  <pre><code>pd.DataFrame({'one':"64 22", 'two':"42 31"})
  </code></pre>
  
  <p>My purpose is to convert each row in the numpy.array to a string that
  will be used for a pandas dataframe.
  Is there some built in pandas function to the rescue?</p>
