title: import problems with scipy.io
body: <p>I've been trying to get started with scipy, but the package is giving me some problems. The tutorial leans heavily on scipy.io, but when I import scypi and try to use scipy.io, I get errors:</p>
  
  <pre><code>In [1]: import scipy
  
  In [2]: help(scipy.io)
  ---------------------------------------------------------------------------
  AttributeError                            Traceback (most recent call last)
  /home/chris/dev/scipy/&lt;ipython-input-2-ef060398b31c&gt; in &lt;module&gt;()
  ----&gt; 1 help(scipy.io)
  
  AttributeError: 'module' object has no attribute 'io'
  </code></pre>
  
  <p>I've run system updates and I uninstalled scipy then installed it again.</p>
  
  <p>Interestingly enough, I can import the module this way:</p>
  
  <pre><code>In [1]: import scipy.io
  </code></pre>
  
  <p>But then when I try to use it, I get an error as soon as I use a method:</p>
  
  <pre><code>In [2]: arr = scipy.array([[1.0,2.0],[3.0,4.0],[5.0,6.0]])
  In [3]: outFile = file('tmpdata1.txt', 'w')
  In [4]: scipy.io.write_array(outFile, arr)
  ---------------------------------------------------------------------------
  AttributeError                            Traceback (most recent call last)
  /home/chris/dev/scipy/&lt;ipython-input-4-46d22e4ff485&gt; in &lt;module&gt;()
  ----&gt; 1 scipy.io.write_array(outFile, arr)
  
  AttributeError: 'module' object has no attribute 'write_array'
  </code></pre>
  
  <p>I'm sure I'm missing something embarrassingly basic, but I've not been able to find an answer to this problem on Google or in the stackoverflow archives.</p>
