from scipy.linalg import _cblas DLL load failed while importing _fblas

Question

I encountered a problem while importing

from pykalman import KalmanFilter

The problem is

I have pip install numpy-1.22.4+mkl-cp38-cp38-win_amd64.whl in python/script, but the problem still exists. Thanks for you attention.
