Unable to load PyFLAGR - Githubissues

Hi there,

Thank you for creating this valuable rank aggregation package. I am attempting to use PyFLAGR but have encountered an issue when creating the aggregator object. Per the instructions in the documentation, I have installed PyFLAGR with pip install pyflagr. I am also able to load pyflagr with:

# Import the PyFLAGR modules for rank aggregation
import pyflagr.Linear as Linear
import pyflagr.Majoritarian as Majoritarian
import pyflagr.MarkovChains as MarkovChains
import pyflagr.Kemeny as Kemeny
import pyflagr.RRA as RRA
import pyflagr.Weighted as Weighted

However, I cannot define an aggregator. The following line raises an OSError:

csum = Linear.CombSUM(norm='score')

OSError                                   Traceback (most recent call last)

    375 else:
    376     self._handle = handle

OSError: dlopen(/Users/an123/miniforge3/envs/myenv/lib/python3.10/site-packages/pyflagr/flagr.dylib, 0x0006): tried: '/Users/an123/miniforge3/envs/myenv/lib/python3.10/site-packages/pyflagr/flagr.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/Users/an123/miniforge3/envs/myenv/lib/python3.10/site-packages/pyflagr/flagr.dylib' (no such file), '/Users/an123/miniforge3/envs/myenv/lib/python3.10/site-packages/pyflagr/flagr.dylib' (no such file)

I would be grateful for your assistance in resolving this issue. Thank you.
