ImportError: DLL load failed: when importing statsmodels [duplicate]

问题

My Python version is 3.5 on win32. I successfully installed Numpy+MKL, Scipy and Statsmodels from here http://www.lfd.uci.edu/~gohlke/pythonlibs/

However, when I run

    import statsmodels as sm

I get the following error:

Traceback (most recent call last):

How can I fix this?
