topic Hi Zhen Z, in Intel® oneAPI Math Kernel Library

Build Scipy With MKL failed

zz — Thu, 08 Jan 2015 06:57:40 GMT

I use command to build numpy first:

python %MYPWD%/%NUMPY_VER%/setup.py config --compiler=msvc build_clib --compiler=msvc build_ext

the site.cfg content is:

[mkl]
library_dirs = C:\Program Files (x86)\Intel\Composer XE 2015\mkl\lib\intel64
include_dirs = C:\Program Files (x86)\Intel\Composer XE 2015\mkl\include
mkl_libs = mkl_rt
lapack_libs =

Then I build scipy with command:

python %MYPWD%/%SCIPY_VER%/setup.py config --compiler=msvc build_clib --compiler=msvc build_ext

It failed with message:

Please give me your suggestion if you have experience about this. Thanks

I have the same issue .

please help

Thanks

Please see this article about

Zhang_Z_Intel — Thu, 08 Jan 2015 17:33:39 GMT

Please see this article about building NumPy and SciPy with MKL: https://software.intel.com/en-us/articles/numpyscipy-with-intel-mkl

The article only discusses building using Intel compilers. But you are using msvc. You may need to make some modifications accordingly.

Do you specify fftw in site.cfg? Is it in the correct location?

Hi Zhen Z,

Ying_H_Intel — Fri, 09 Jan 2015 07:33:58 GMT

Hi Zhen Z,

The problem of unresolved external symbol zfftf_ referenced in function zfft_ are related to the different name conversion of C and fortran under windows and linux, 32bit and intel64 bit. In the source code : there are three micro to control them NO_APPEND_FORTRAN, UPPERCASE_FORTRAN, PREPEND_FORTRAN.

Here are some related information i found on internet,

http://mail.scipy.org/pipermail/scipy-user/2011-April/029192.html => two patch.

Please check them or manually to add either /DNO_APPEND_FORTRAN' some place

'/DPREPEND_FORTRAN'. /DNO_APPEND_FORTRAN','/DUPPERCASE_FORTRAN'

and let us know how they work.

Best Regards,

Ying

Hi, Zhang Z

Can you show me how to specify fftw in site.cfg?

I attached my old site.cfg.

Hi, Ying

Hi, Ying

After add the three options, I got the new error. What's options I can use?

Kaushal_S_ — Thu, 29 Jan 2015 01:01:00 GMT

I'm trying to build scipy-0.15.1 using Visual Studio 2013 (msvc12) against numpy 1.9.1 and Python 2.7.6 x64 all built with Visual Studio 2013.

~~I'm~~ I was stuck at the same location as well.

I looked at the symbols in vode.lib and I see the DVODE and ZVODE symbols, but no _DVODE and _ZVODE symbols. ~~Is that the problem? I'll investigate further and see if I can figure this out.~~ That is the problem. You can temporarily undefine PREPEND_FORTRAN macro for vodemodule.

Thanks,
Kaushal

zz — Thu, 29 Jan 2015 01:10:34 GMT

I have build three times to finish it.

1 genreal build with no option to change upper/lower case

2 run build with option ""-DUPPERCASE_FORTRAN -DNO_APPEND_FORTRAN -DPREPEND_FORTRAN "

3 run build again with option ""-DUPPERCASE_FORTRAN -DNO_APPEND_FORTRAN "

Hope this can help you.

Below is part of my build script:

pushd %MYPWD%\%SCIPY_VER%

python %MYPWD%/%SCIPY_VER%/setup.py clean --all

python %MYPWD%/%SCIPY_VER%/setup.py config --compiler=msvc --fcompiler=intelvem build_clib --compiler=msvc --fcompiler=intelvem build_ext >> %MYPWD%\build1.log

python %MYPWD%/%SCIPY_VER%/setup.py config --compiler=msvc --fcompiler=intelvem build_clib --compiler=msvc --fcompiler=intelvem build_ext "-DUPPERCASE_FORTRAN -DNO_APPEND_FORTRAN -DPREPEND_FORTRAN ">> %MYPWD%\build2.log

python %MYPWD%/%SCIPY_VER%/setup.py config --compiler=msvc --fcompiler=intelvem build_clib --compiler=msvc --fcompiler=intelvem build_ext "-DUPPERCASE_FORTRAN -DNO_APPEND_FORTRAN " >> %MYPWD%\build3.log

Hi, Zhen and Kaushal

Yuan_C_Intel — Fri, 30 Jan 2015 08:47:00 GMT

Hi, Zhen and Kaushal

The two Fortran compiler options: "/Qlowercase /us" used in numpy scripts are already removed from Intel(R) Visual Fortran 15.0.

The suggested replacement are /names:lowercase and /assume:underscore

Try update numpy\distutils\fcompiler\intel.py:

Under class IntelVisualFCompiler(BaseIntelFCompiler):

Change:

def get_flags(self):

opt = ['/nologo', '/MD', '/nbs', '/Qlowercase', '/us']

to:

def get_flags(self):

opt = ['/nologo', '/MD', '/nbs', '/names:lowercase', '/assume:underscore']

Build and install passed successfully.

Thanks
