pytest issues with get_native_int

[anithag]

After installing openfhe-python, I am trying to run pytest in the project root directory. I get the following errors. It must be something simple. Can you help fix? I am using Mac OSX Sonoma (Apple M2).

I want to provide a bit more info to see if this is an installation issue. openfhe is installed in my home directory. After build and install of openfhe-python, I have set PYTHONPATH and LD_LIBRARY_PATH to include openfhe dynamically shared libraries. So far it seemed reasonable without any issues.

Later, when I run pytest, I got the error:

Traceback:
/opt/homebrew/Cellar/python@3.11/3.11.7_1/Frameworks/Python.framework/Versions/3.11/lib/python3.11/importlib/__init__.py:126: in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
tests/test_serial_cc.py:4: in <module>
    import openfhe as fhe
openfhe/__init__.py:1: in <module>
    from openfhe.openfhe import *
E   ModuleNotFoundError: No module named 'openfhe.openfhe'

What should my PYTHONPATH include at this point? Note that if it includes only $HOME//Users/anitha_gollamudi/openfhe-development/install/lib I get No module named openfhe.openfhe error.

setting export PYTHONPATH=openfhe-python/build:$PYTHONPATH solved the issue. This is not mentioned in the documentation; only OpenFHE libraries were mentioned, and I assumed that they referred to libraries from openfhe-development.
