scipy.linalg.solve CRASH when used with IntelOneAPI 2024.2 MKL on Windows 11

Hi,

I have raised this issue with scipy :https://github.com/scipy/scipy/issues/21997

Note: ifort was by default selected here for compilation.

icx and ifx combination gives compilation errors on windows.

Please let me know how to go ahead with this problem.

Numpy 2.1.3 built using following commands:

call "C:\Program Files (x86)\Intel\oneAPI\setvars.bat" intel64
set CC=clang-cl
set CXX=clang-cl

python -m pip install . -Cbuild-dir=build -Csetup-args=-Dallow-noblas=false -Csetup-args=-Dblas-order=mkl -Csetup-args=-Dlapack-order=mkl -Csetup-args=-Dblas=mkl -Csetup-args=-Dlapack=mkl

Scipy 1.13.1 built using following commands:

call "C:\Program Files (x86)\Intel\oneAPI\setvars.bat" intel64

python -m pip install --no-binary :all: pybind11
python -m pip install --no-binary :all: pythran

set CC=clang-cl
set CXX=clang-cl

python -m pip install . -Csetup-args=-Dblas=mkl -Csetup-args=-Dlapack=mkl

scipy.linalg.solve crashed:

Reproducing Code Example

from scipy import integrate, optimize, linalg, signal, stats, interpolate
import numpy as np
A = np.array([[3, 1], [1, 2]])
b = np.array([9, 8])
x = linalg.solve(A, b)

Error message

>>> x = linalg.solve(A, b)

It just crashed no output.

Hi Ashish,

Looks I can't reproduce your issue in my side. I am using oneAPI 2025.0, can you try the newer oneAPI version too?

C:\Program Files (x86)\Intel\oneAPI>python

Python 3.12.3 (tags/v3.12.3:f6650f9, Apr 9 2024, 14:05:25) [MSC v.1938 64 bit (AMD64)] on win32

Type "help", "copyright", "credits" or "license" for more information.

>>> from scipy import integrate, optimize, linalg, signal, stats, interpolate

>>> import numpy as np

>>> A = np.array([[3, 1], [1, 2]])

>>> b = np.array([9, 8])

>>> x = linalg.solve(A, b)

>>> x

array([2., 3.])

regards,

ruqiu
