python 2.7 - Cython: ImportError: DLL load failed -

-

i have compiled cython code , call within python script. worked until recently. it's not working more , gives error

importerror: dll load failed: initialization of dll file failed.

i'm on win7 64bit, anaconda distribution 2.0.1. recompiling cython code didn't help.

import time import implied_vola  underlyingprice=5047 strikeprice=4600 interestrate=0.03 daystoexpiration=218 price=724.5 optiontype='call' start=time.time() vola= implied_vola.implied_vola(underlyingprice,strikeprice,interestrate,daystoexpiration,price,optiontype) end=time.time() time=float(end-start)

any idea do? how check if compiles using windows sdk compilation , how check cython version in ipython?
