numpy.core.multiarray failed to import after installing asammdf package

Question

I try to read the mf4 file which has acoustic signal.

from asammdf import MDF
data = MDF('file1.mf4')

The packages that I installed are

asammdf 7.0.7

numpy 1.22.3

ImportError: DLL load failed while importing _multiarray_umath: The specified module could not be found.

Traceback (most recent call last):

ImportError: numpy.core.multiarray failed to import

I already checked the numpy version pip install -U numpy It said Requirement already satisfied: numpy in c:\users\susan\anaconda3\envs\env1\lib\site-packages (1.22.3)

May I know how can I solve this issue? Thank you.
