Decode a qr-code in Python 3.6 in Anaconda 4.8.3 on 64 bit Windows?

How can I decode a qr code in python 3.6 in Anaconda 4.8.3 a Windows 10 Pro N 64 bit installation?

Most solutions require Pillow with zbar. However, it appears zbar is only available on 32bit windows installations. Furthermore, pip install zbarlight yields:

ERROR: No matching distribution found for pyzbarlight

To try and decode a qr code in python 3.6 in Anaconda 4.8.3 on a Windows 10 Pro N 64 bit device, I tried the following code:

# Set up virtual environment in Anaconda
# conda create --name test36 python=3.6
# conda activate test36

# Install pip in the `test36` environment:
# E:/ProgramData/Anaconda3/envs/test36/Scripts/pip install pyzbar

# Source: https://anaconda.org/anaconda/pillow
# conda install -c anaconda pillow

from pyzbar.pyzbar import decode
from PIL import Image
decode(Image.open('elbow.png'))

Which yields error:

OSError: [WinError 126] The specified module could not be found

To recap the following steps enabled decoding a qr code in a python 3.6 environment in Anaconda prompt 4.8.3 on a 64 Windows 10 Pro N device:

The steps assume python 3.6 environment is installed and activated, which can be done with.

conda create -n py36 python=3.6 anaconda
conda activate py36

Pillow installation

Source:https://anaconda.org/conda-forge/pillow

Command:

conda install -c conda-forge pillow

Pyzbar installation

Source: Decode a qr-code in Python 3.6 in Anaconda 4.8.3 on 64 bit Windows?

Command:

pip install pyzbar

Then from source: https://www.microsoft.com/en-US/download/details.aspx?id=40784 download vcredist_x64.exe (if you have an 64 bit pc, for x86 pick the 32 bit version). You don't even have to restart anaconda prompt and you can verify pyzbar with a python file named test.py with content:

from pyzbar.pyzbar import decode
decode(Image.open('test.png'))

Next include an image named test.png in the same folder as test.py. You can execute test.py in Anaconda prompt in a python 3.6 environment with command:

python test.py

It shouldn't output anything.

Windows error message

If you see an ugly ImportError when importing pyzbar on Windows you will most likely need the Visual C++ Redistributable Packages for Visual Studio 2013. Install vcredist_x64.exe if using 64-bit Python, vcredist_x86.exe if using 32-bit Python.

visit and read please here https://pypi.org/project/pyzbar/ or github homepage https://github.com/NaturalHistoryMuseum/pyzbar

I use Ubuntu for my purposes, so I cannot check this out, but in home project README they give information about ugly ImportError. If they talk about 64 bit installation, then pyazbar works on 64-bit Windows, please doublecheck that Visual C++ Redistributable Packages for Visual Studio 2013 is properly installed and other requirements are satisfied also.
