`UserWarning: mkl-service package failed to import ` in the import example
Lancashire3000 opened this issue · comments
Hi,
I tried to do the example about import in https://github.com/ylikx/forpy#import-a-python-module-in-fortran
By gfortran -c forpy_mod.F90
and gfortran py-import.f90 forpy_mod.o python3-config --ldflags --embed
-fno-lto -static-libgfortran (I named the file as py-import.f90
)
then run a.out
, I got
/home/user/intel/oneapi/intelpython/latest/envs/idp-2/lib/python3.8/site-packages/numpy/__init__.py:159: UserWarning: mkl-service package failed to import, therefore Intel(R) MKL initialization ensuring its correct out-of-the box operation under condition when Gnu OpenMP had already been loaded by Python process is not assured. Please install mkl-service package, see http://github.com/IntelPython/mkl-service
from . import _distributor_init

My python 3.8.11 is from https://software.intel.com/en-us/python-distribution
and https://www.intel.com/content/www/us/en/developer/articles/technical/using-intel-distribution-for-python-with-anaconda.html
, not sure if intel-python
has any issue with forpy
If I create a new conda environment with python=3.8, conda install -c conda-forge fypp
, then
gfortran -c forpy_mod.F90
gfortran py-import.f90 forpy_mod.o python3-config --ldflags --embed
-fno-lto
./a.out
I got
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Anaconda changed how its cpython is built. This should help: #25
Thank you so much! gfortran py-import.f90 forpy_mod.o python3-config --ldflags --embed
-fno-lto -static-libgfortran -Xlinker -export-dynamic
leads to Today is 2022-01-13
It works!
