Important note: After installation, append this line

export LD_LIBRARY_PATH=/opt/intel/oneapi/mkl/2024.1/lib:$LD_LIBRARY_PATH

in ~/.bashrc, ~/.zshrc, etc. In order to avoid this ImportError.

I did the changes suggested by @bear in the site files(hint: edit site files and install using --skipinteg) and it found the mkl library which previously didn't (FOUND: libraries = ['mkl_rt', 'pthread']). The thing is that if you dont make those changes it doesn't found the mkl library and still builds, so it's easy to believe that everything is working but your numpy is using another blas library.

@bear Thanks ! It works. BTW, when compile, -openmp may be deprecated, it suggests using -qopenmp

The site.cfg is not correct, after changed to the following, can import correctly after installed. [mkl] library_dirs = /opt/intel/mkl/lib/intel64 include_dirs = /opt/intel/mkl/include mkl_libs = mkl_rt lapack_libs =

and can this package be compiled using -iopm5 instead of -openmp ?

@trovao Thanks ! I install the patchelfmod in aur (this package needs update, for example the pkgname is patchelfmod however the source dir is patchelf), and numpy.test() works fine. and i think a patch in linking to libirc.so is needed :) anyway, thanks for your solution !

@trovao I can only find patchelf in my archlinux, where could I get patchelfmod ? BTW: I also tried to add -lirc in LDFLAGS, is it correct to do so?

trovao commented on 2016-02-25 11:51 (UTC)

@liubenyuan, @benob I've solved this with patchelfmod by adding a dependency explicitly on the shared object files: $ sudo patchelfmod -a libirc.so /usr/lib/python2.7/site-packages/numpy/linalg/_umath_linalg.so sudo patchelfmod -a libirc.so /usr/lib/python3.5/site-packages/numpy/linalg/_umath_linalg.cpython-35m-x86_64-linux-gnu.so I've tried tweaking the intelccompiler.py to include -lirc, but it seems my flags weren't enough.

@benob same problem here. using intel-mkl 2016.1.30

Installs fine with intel parallel studio xe 2015, but when I import numpy I get the following error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/site-packages/numpy/__init__.py", line 170, in <module> from . import add_newdocs File "/usr/lib/python2.7/site-packages/numpy/add_newdocs.py", line 13, in <module> from numpy.lib import add_newdoc File "/usr/lib/python2.7/site-packages/numpy/lib/__init__.py", line 18, in <module> from .polynomial import * File "/usr/lib/python2.7/site-packages/numpy/lib/polynomial.py", line 19, in <module> from numpy.linalg import eigvals, lstsq, inv File "/usr/lib/python2.7/site-packages/numpy/linalg/__init__.py", line 51, in <module> from .linalg import * File "/usr/lib/python2.7/site-packages/numpy/linalg/linalg.py", line 29, in <module> from numpy.linalg import lapack_lite, _umath_linalg ImportError: /usr/lib/python2.7/site-packages/numpy/linalg/_umath_linalg.so: undefined symbol: _intel_fast_memset Preloading the libirc.so library fixes the problem, but I would like a better solution.
