Numpy 1.10.2 + MKL = crash (Windows)

Whether using Anacondas Numpy or the one packaged here Numpy crashes with some functions. The error messages are Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll.

and

The procedure entry point mkl_aa_fw_get_max_memory could not be located in the dynamic link library C:\Program Files\Python 3.5\lib\site-packages\numpy\core\mkl_intel_thread.dll..

Numpy 1.9.2 (tested on Python 3.3.5) works fine (but doesn’t have above .dll in its directory, either).

For the time being I’ve downgraded to Numpy 1.9. I know you don’t test against MKL but maybe you’ve got some hints?

@cgohlke These are the DLLs found in my Windows directory:

['System32\\libiomp5md.dll',
 'System32\\mkl_core.dll',
 'System32\\mkl_def.dll',
 'System32\\mkl_intel_thread.dll',
 'SysWOW64\\libiomp5md.dll',
 'SysWOW64\\mkl_core.dll',
 'SysWOW64\\mkl_intel_thread.dll',
 'SysWOW64\\mkl_p4.dll',
 'SysWOW64\\mkl_p4m.dll',
 'SysWOW64\\mkl_p4m3.dll',
 'SysWOW64\\mkl_p4p.dll']

Trying to reset my PATH with SET PATH=; before invoking python still crashes but removing above DLLs entirely from the Windows directory stops the crash. Seems like a path precedency issue @carlkl.

Hi guys. Just in case someone is still with this problem. I have numpy 1.12 + mkl and had the same issue. I uninstalled Amplitube 3 and now everything its working!
