ImportError for py3.6 on macos 10.12.3 #100

Closed everdark closed 7 years ago

When trying from fastFM import als I got the following error:

ImportError: dlopen(/usr/local/lib/python3.6/site-packages/ffm.cpython-36m-darwin.so, 2): Symbol not found: _cs_di_norm
  Referenced from: /usr/local/lib/python3.6/site-packages/ffm.cpython-36m-darwin.so
  Expected in: flat namespace
 in /usr/local/lib/python3.6/site-packages/ffm.cpython-36m-darwin.so

I've seem similar issue for other people using other platform/version but not solution as well. I installed the package with pip3 install fastFM without any error.

My system info:

macOS 10.12.3
Python 3.6.0

This might be because we currently don't provide python 3.6 wheels and the source install fails. Creating the wheels should be possible. _cs_di_norm indicates that the cython build didn't work properly and the CXSparse dependency hasn't been compiled properly.

I try instead use a virtualenv with py 3.5. everything is fine now.
