Minimal example opencv, pyinstaller, conda

I'm trying to get a minimal example working using pyinstaller and opencv inside a conda environment.

So far, what I'm doing is:

conda create -n minimal_example python=3 pyinstaller opencv

which leaves me with the following packages:

I have a script called minimal_build.py with the following content:

print('Importing numpy')

import numpy as np

print(np.__version__)
print(np.__file__)

print('Importing OpenCV')

import cv2

I'm trying to package that script into an executable running

pyinstaller minimal_build.py

When running the resulting exe, I get the following output:

Importing numpy
C:\Users\me\Anaconda3\envs\minimal_example\lib\site-packages\PyInstaller\loader\pyimod03_importers.py:623: UserWarning: mkl-service package failed to import, therefore Intel(R) MKL initialization ensuring its correct out-of-the box operation under condition when Gnu OpenMP had already been loaded by Python process is not assured.

  exec(bytecode, module.__dict__)

  File "mkl\_mkl_service.pyx", line 27, in init mkl._py_mkl_service
ModuleNotFoundError: No module named 'six'
[9644] Failed to execute script minimal_build

So I'm guessing, that it tries to import numpy from my user folder instead of the package. What am I doing wrong?

I happened to have the same problem as you

Here is the solution I tried:

conda create -n minimal_example python=3.7 pyinstaller
conda activate minimal_example
pip install opencv-python

not conda install opencv

my conda list:

# Name                    Version                   Build  Channel

pyinstaller               3.6              py37h62dcd97_5    defaults
python                    3.7.7                h81c818b_4    defaults
pywin32                   227              py37he774522_1    defaults
pywin32-ctypes            0.2.0                 py37_1000    defaults
setuptools                47.3.1                   py37_0    defaults
sqlite                    3.32.3               h2a8f88b_0    defaults

wincertstore              0.2                      py37_0    defaults
zlib                      1.2.11               h62dcd97_4    defaults

then

pyinstaller -F path/to/your/python-file -p path/to/your/venv/python.exe
