title: pycuda._driver import error (Windows)
body: <p>I am trying to run pycuda on my windows 7 machine. I have installed the following-</p>
  
  <p><strong>1. Python 2.7.9</strong></p>
  
  <p><strong>2. cuda_7.0.28_windows</strong></p>
  
  <p><strong>3. numpy-1.9.2-win32-superpack-python2.7</strong></p>
  
  <p><strong>4. pycuda-2014.1+cuda6514-cp27-none-win32</strong> (<em>whl from christopher gohlke's libraries page</em>)</p>
  
  <p><strong>5. Visual Studio 2013 community edition</strong></p>
  
  <p>All the above installations were successful but when I run the code below (<em>its a long code but the import statements should be enough to describe the problem</em>)</p>
  
  <pre><code>from __future__ import division
  import numpy as np
  import pycuda.driver as drv
  from pycuda.compiler import SourceModule
  
  import pycuda.autoinit
  import numpy.testing
  </code></pre>
  
  <p>I get the following error-</p>
  
  <pre><code>Traceback (most recent call last):
  File "D:\trash\cuda_test.py", line 3, in &lt;module&gt;
      import pycuda.driver as drv
  File "C:\Python27\lib\site-packages\pycuda\driver.py", line 2, in &lt;module&gt;
      from pycuda._driver import *  # noqa
  ImportError: DLL load failed: The specified module could not be found.
  </code></pre>
  
  <p>Any idea what could the problem be??</p>
