Using multiprocessing in Python ends in ImportError
<p>I'm trying to run simple programs from Python doc using <code>multiprocessing</code>, however I always get errors like:</p>

<pre><code>Traceback (most recent call last):                               
  File "Poolexample.py", line 1, in &lt;module&gt;
    from multiprocessing import Pool
ImportError: cannot import name Pool
</code></pre>

<p>or similarly, <code>cannot import name Process</code>. Anyone knows why does Python send me such errors?</p>
