title: How to fix "ImportError: cannot import name _AES" from Crypto.Cipher when using pycrypto on Windows?
body: <p>I have AES inside the Cipher module inside Crypto (<code>Python27\Lib\Crypto\Cipher\AES</code>).</p>
  <p>When I try to do</p>
  <pre><code>from Crypto.Cipher import AES
  </code></pre>
  <p>I get the following error:</p>
  <pre><code>Traceback (most recent call last):
    File &quot;&lt;pyshell#1&gt;&quot;, line 1, in &lt;module&gt;
      from Crypto.Cipher import AES
    File &quot;C:\Python27\lib\Crypto\Cipher\AES.py&quot;, line 50, in &lt;module&gt;
      from Crypto.Cipher import _AES
  ImportError: cannot import name _AES
  </code></pre>
  <p>But I can <code>import</code> another module like</p>
  <pre><code>from Crypto.Cipher import blockalgo
  </code></pre>
  <p>That works fine.</p>
  <p>So, I'm guessing there is some error in the AES module?</p>
