在Windows上的python导入模块时，是否有任何常见的方法来调查此类错误？ DependencyWalker没有多大帮助。
例如我现在在Windows 8.1上遇到Theano和Anaconda Python的问题。出于某种原因，python无法为libgpuarray加载DLL，我想知道如何调查此问题。
以下是错误的样子。
C:\Users\test>python
Python 3.6.0 |Anaconda 4.3.1 (64-bit)| (default, Dec 23 2016, 11:57:41) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import theano
ERROR (theano.gpuarray): pygpu was configured but could not be imported or is too old (version 0.6 or higher required)
NoneType: None
>>> import pygpu
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\test\Anaconda3\lib\site-packages\pygpu\__init__.py", line 7, in <module>
from . import gpuarray, elemwise, reduction
ImportError: DLL load failed: The specified module could not be found.
这是Process Monitor日志：

所以它看起来像DLL被发现并加载到进程空间。
