size of executable using pyinstaller and numpy

Question

I wrote a short program main.py using numpy and Qt:

from PyQt5 import QtWidgets
import numpy as np
import sys

if __name__ == \'__main__\':
             


        

Answer 1

Thanks to the user balletpiraat I found a solution.

Install numpy with: conda install -c conda-forge numpy

To test this I created two anaconda environments. Environment "normalnumpy" was created with:

conda create -n normalnumpy python=3.7
activate normalnumpy
conda install numpy
pip install pyinstaller

resulting in:

altgraph                  0.16.1                    <pip>

Environment "extranumpy" was created with:

activate extranumpy
conda install -c conda-forge numpy
pip install pyinstaller

I tested both environments with "main.py":

import numpy as np
if __name__ == '__main__':
    test = np.array([42])
    print(test)

and

pyinstaller --onefile main.py

the "normalnumpy" executable is 228MB, the "extranumpy" executable is 10MB.

Answer 2

Have you tried excluding modules? This is a common problem. Also you might want to check out:

Reducing size of pyinstaller exe

Worth mention, are you using Anaconda? A fresh oracle box python system and less of a huge file.

I believe in there docs somewhere you can adjust where the directories are found.
