pycuda._driver import error (Windows)

I am trying to run pycuda on my windows 7 machine. I have installed the following-

1. Python 2.7.9

2. cuda_7.0.28_windows

3. numpy-1.9.2-win32-superpack-python2.7

4. pycuda-2014.1+cuda6514-cp27-none-win32 (whl from christopher gohlke's libraries page)

5. Visual Studio 2013 community edition

All the above installations were successful but when I run the code below (its a long code but the import statements should be enough to describe the problem)

from __future__ import division
import numpy as np
import pycuda.driver as drv
from pycuda.compiler import SourceModule

import pycuda.autoinit
import numpy.testing

I get the following error-

Traceback (most recent call last):
File "D:\trash\cuda_test.py", line 3, in <module>
    import pycuda.driver as drv
File "C:\Python27\lib\site-packages\pycuda\driver.py", line 2, in <module>
    from pycuda._driver import *  # noqa
ImportError: DLL load failed: The specified module could not be found.

Any idea what could the problem be??

The solution involved installing the version of CUDA supported by the library. I had a higher version. The pycuda library's filename can be decomposed as follows to identify the versions of CUDA and Python supported by it-

Filename: pycuda-2014.1+cuda6514-cp27-none-win32

Python version supported: 2.7 (from cp27)
CUDA version supported: 6.5.14 (from cuda6514)
