title: Unable to import modules in Orange python environment but Orange GUI works
body: <p>I would like to use the <code>Orange.associate</code> and <code>Orange.data.sql</code> modules in python scripting but in both cases I get AttributeError after <code>import Orange</code>.</p>
  
  <p>However, in the Orange GUI both widgets work as expected.</p>
  
  <p>When I check the python path with <code>sys.path</code>, the python interpreter has access to the Orange libraries, the global dist-packages and the local site-packages.</p>
  
  <p>I have ubuntu 14.04 running and I installed Orange 3.3 into the <code>/opt</code> directory, following the instructions here:
  <a href="http://orange.biolab.si/download/linux/" rel="nofollow">http://orange.biolab.si/download/linux/</a></p>
  
  <p>I am very unfamiliar with python environments and quite a beginner with Linux as well, so any hint is appreciated.</p>
  
  <p>Here is an example of what I did:</p>
  
  <pre><code>(orange3env)bdukai@balazs-dukai:/opt/orange$ python
  Python 3.4.3 (default, Oct 14 2015, 20:28:29) 
  [GCC 4.8.4] on linux
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; import Orange
  &gt;&gt;&gt; Orange.data.sql
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  AttributeError: 'module' object has no attribute 'sql'
  &gt;&gt;&gt; Orange.data.Table
  &lt;class 'Orange.data.table.Table'&gt;
  </code></pre>
