Access violation in mkl_set_interface_layer with Python 3

ydl — Thu, 05 Apr 2018 22:02:01 GMT

Using mkl_set_interface_layer from Python 3 on Windows 10 with the latest MKL installed gives an access violation. Specifically this code:

from ctypes import *
mkl = cdll.LoadLibrary('mkl_rt')
mkl.mkl_set_interface_layer(c_int(1))

produces this error:

OSError: exception: access violation reading 0x0000000000000001

Note using c_int(0) in place of c_int(1) gives an analogous error. Variables in the console are set using mklvars.bat (notably the PATH variables are set properly), and I have checked that several of the cblas_* functions are working. Is there some library I have to load, or specify a calling convention?

Thanks.

>> the latest MKL -- do you

>> the latest MKL -- do you mean MKL v. 2018 u2? please quick check mkl_version.h header to take this info.

Yes, I mean that one.

Yes, I mean that one. Specifically, I have, in mkl_version.h,

#define __INTEL_MKL_BUILD_DATE 20180128

#define __INTEL_MKL__ 2018
#define __INTEL_MKL_MINOR__ 0
#define __INTEL_MKL_UPDATE__ 2

#define INTEL_MKL_VERSION 20180002

yes, we confirmed the problem
