Hello,
I have been trying to install the Python wrapper on my Windows with conda based on the instructions provided in GitHub - openfheorg/openfhe-python: Official Python wrapper for OpenFHE. Current release is v0.8.9 (released on September 10, 2024).
I installed OpenFHE 1.1.3+ as instructed and then I cloned the repository for the Python wrapper in another directory and created a new environment using Anaconda prompt. I then used the following commands after making the build directory since the ones provided in the documentation were not working in my Anaconda prompt.
cmake -G “MinGW Makefiles” …
mingw32-make
mingw32-make install
Afterwards, I created the lib directory and since I did not have any .so files, I moved the openfhe.cp311-win_amd64.pyd file into the lib directory. I also added the following directories into the path variables:
set PYTHONPATH=C:\Users\mahta\openfhe-python\lib;%PYTHONPATH%
set PATH=%PATH%;C:\Program Files (x86)\OpenFHE\lib
but when I try to run pytest I get the following error messages:

I tried multiple times to rebuild the openfhe-development and openfhe-python but I still face the same issue every time.
Afterward, I decided to try using Docker for that and the installation was successful but when I opened the notebook on http://localhost:8888/ I was not able to import openfhe library.
!pip show openfhe
WARNING: Package(s) not found: openfhe
Could you please assist me in gaining access to the Python library using either method?
Thanks!
