title: How python organized its code in the folder?
body: <p>I am beginner for python and get stack at how python organize its code. </p>
  
  <p>For example:
  <a href="https://github.com/HIPS/neural-fingerprint/blob/master/examples/regression.py" rel="nofollow noreferrer">https://github.com/HIPS/neural-fingerprint/blob/master/examples/regression.py</a></p>
  
  <p>In the <code>regession.py</code>, it will import the <code>neuralfingerprint</code> directory. When I run the <code>regession.py</code> in anaconda python, it says that the <code>neuralfingerprint</code> doesn't exist. I need to copy <code>neuralfingerprint</code> again to make sure <code>neuralfingerprint</code> and  <code>regession.py</code> are in the same folder.</p>
  
  <p>Any convient way? or why the author put  <code>regession.py</code> and <code>neuralfingerprint</code> put them in different folder?</p>
  
  <p>Thanks.</p>
