title: How to convert ndarray to array?
body: <p>I'm using pandas.Series and np.ndarray.</p>
  
  <p>The code is like this</p>
  
  <pre><code>&gt;&gt;&gt; t
  array([[ 0.,  0.,  0.],
         [ 0.,  0.,  0.],
         [ 0.,  0.,  0.]])
  &gt;&gt;&gt; pandas.Series(t)
  Exception: Data must be 1-dimensional
  &gt;&gt;&gt;
  </code></pre>
  
  <p>And I trie to convert it into 1-dimensional array:</p>
  
  <pre><code>&gt;&gt;&gt; tt = t.reshape((1,-1))
  &gt;&gt;&gt; tt
  array([[ 0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.,  0.]])
  </code></pre>
  
  <p>tt is still multi-dimensional since there are double '['.</p>
  
  <p><strong>So how do I get a really convert ndarray into array?</strong></p>
  
  <p>After searching, <a href="https://stackoverflow.com/questions/11334906/convert-np-ndarray-to-np-array-in-python">it says they are the same</a>. However in my situation, they are not working the same. </p>
