Cannot import mkl_fft after manual build and install of v1.3.10 on W11

[NairoDorian]

Hello I installed oneAPI BaseToolKit

I added the environment variables and manually installed v1.3.10 of mkl_fft using the setup.py install command

No when I try to import mkl_fft in a python script in the venv I installed everything I get this error :

import mkl_fft
Traceback (most recent call last):
File "", line 1, in
File "C:...\MKL_FFT\venv\Lib\site-packages\mkl_fft_init_.py", line 27, in
from ._pydfti import (fft, ifft, fft2, ifft2, fftn, ifftn, rfft, irfft,
ImportError: DLL load failed while importing _pydfti: The specified module could not be found.

I tried another version of python but it didn't solve my issue

Do you have any idea why it might not work ?

I am desperate at figuring out to use the intel mkl fft or the ipp ftt, whatever is the fastest

Even tried to use the Intel® Distribution for Python with 1.3.8 of mkl_fft, still cannot import it
\venv\Lib\site-packages\mkl_fft_init_.py", line 27
from ._pydfti import (fft, ifft, fft2, ifft2, fftn, ifftn, rfft, irfft,
r = previousimport(*args, **kw)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named 'mkl_fft._pydfti'

Could you please check if the advice from IntelPython/dpctl#1745 (comment) helps?

This should allow Python find MKL library DLLs as failure to find them trips ModuleNotFoundError or ImportError.

Additionally, please check that \venv\Lib\site-packages\mkl_fft folder does contains the _pydfti.*.pyd file.

now i get this error :

import mkl_fft
File "C:\Program Files\Python311\Lib\site-packages\mkl_fft_init_.py", line 31, in
import mkl_fft.interfaces
File "C:\Program Files\Python311\Lib\site-packages\mkl_fft\interfaces_init_.py", line 27, in

Please make sure that mkl-service package is installed, and you have \venv\Lib\site-packages\mkl folder with files in it.
