OSError: no file with expected extension

Hi, I ran into this problem on OS 10.15.1

OSError: no file with expected extension

Hi, unfortunately, I have not tested CPrior on macOS since initially only supported Linux and Windows OS. However, in _lib/cprior.py it is possible to add a check to macOS "darwin" platform. Did you compile a shared library for macOS? does it have .so or .dylib extension? Any help with other OS is welcome.

[guillermo-navas-palencia]

Hi,
Files setup.py and _lib/cprior.py to read the shared library have been updated to fix this issue. You just need to create a cprior.dylib shared library and save it in _lib/. Let me know if that worked for you.
