title: nd array object of numpy module
body: <p>I am writing code to find out if a point 'npA' from the set 'pA' has a closest neighbour from a set 'pB' containing randomly generated points. (In the code I have a single point but in my application, the points would be randomly generated). My problem is that I am unable to view/access the resulting list from the <code>cKDTree.query_ball_point</code> result. </p>
  
  <p>In my variable explorer the result displays the type as <code>object</code> and the value as <code>ndarray object of numpy module</code>. When I try to view/access this list i.e. <code>result</code>, a window pops up that says <code>object arrays are currently not supported</code>. I would like to know how I can view this list or convert it to an array that I can use for some analysis later on.</p>
  
  <pre><code>from scipy.spatial import cKDTree
  import numpy as np
  
  pA = np.array([[0.000,0.000],[0.300,0.000],[0.600,0.000],[0.000,0.300], [0.300,0.300],[0.600,0.300],[0.000,0.600],[0.300,0.600],[0.600,0.600]])
  
  pB = np.array([[0.300,0.600]])
  npA =[[pA[0,0],pA[0,1]]]
  npA = np.array(npA)
  
  tree = cKDTree(npA)
  result = tree.query_ball_point(pB,0.100) #I wish to view the list stored in result
  </code></pre>
