hi all,

i am trying to make an exe file using pyinstaller. while clicking on the exe file, its giving me fatal error with stating 'unable to open the exe'. So i checked in cmd line , there is the issue with numpy.
Then i uninstalled and installed it again, nut still the issue is there.

Reproducing code example:

After opeing the exe file, error is :

while making the exe file using pyinstaller command :

This is likely an issue with pyinstaller not copying the dlls from python into the final installation, maybe related to the new python/numpy versions. Maybe related to gh-14807.
It seems pyinstaller changed the hook for numpy in pyinstaller/pyinstaller#4593, you might have more luck if you try a HEAD version of pyinstaller.

I think it is Python 3.8 problem - somehow it does not respect PATH env variable.
I am using Numpy with Intel MKL for Windows taken from https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy. It comes with whole distribution of MKL library in DLLs folder packaged to Numpy wheel. Considering that I am using MKL from C++ code as well, I am having standalone installation, so I prefer to delete packaged version and to use standalone added to PATH env variable.
What I found right now, is that in Python 3.8 I can't do it anymore - it does not respect my PATH variable settings and importing Numpy results in error as for topic starter.
I tried to uninstall Python 3.8.1 and install Python 3.7.6 and Numpy 1.18.1 is working as expected successfully loading my standalone MKL dlls.
Also with Python 3.8.1 I tried to move MKL libraries into C:\Windows\System32 directory, that way it also successfully imports Numpy. I guess it looks into default directories only, without using user's custom settings.
