title: No Module Name index
body: <p>Hi I'm new to python and also to pyflann. I did install pyflann and tried to run the test example of it. After executing, I'm getting an error</p>
  
  <pre><code>from pyflann import FLANN
  import numpy as np
  
  dataset = np.array(
       [[1., 1, 1, 2, 3],
       [10, 10, 10, 3, 2],
       [100, 100, 2, 30, 1]
       ])
  testset = np.array(
       [[1., 1, 1, 1, 1],
       [90, 90, 10, 10, 1]
       ])
  flann = FLANN()
  result, dists = flann.nn(dataset, testset, 2, 
  algorithm="kmeans"branching=32, iterations=7, checks=16)
  print (result)
  print (dists)
  
  dataset = np.random.rand(10000, 128)
  testset = np.random.rand(1000, 128)
  flann = FLANN()
  result, dists = flann.nn(dataset, testset, 5, algorithm="kmeans", 
  branching=32, iterations=7, checks=16)
  print (result)
  print (dists)
  </code></pre>
  
  <p>When I try to execute the above code, I get something like this</p>
  
  <pre><code>from index import *
  
  ModuleNotFoundError: No module named 'index'
  </code></pre>
  
  <p>Can somebody ans this as I've those files in my site-packages of pyflann and my python version is 3.6. And how should i proceed to run the above code.</p>
