body: <p>i had succesfully installed numpy (numpy-1.6.2-win32-superpack-python2.7.exe). But, whenever i try to call any functions i am getting following the error below. Thanks in advance for help. </p>
  
  <pre><code>import numpy as np
  if __name__ == "__main__":
      k = np.arange(10)
  
  AttributeError: 'module' object has no attribute 'arange'
  </code></pre>
