[BUG] Installation error due to `cornac`'s numpy dependency in setup.py

[Jun Ki Min]

Description

cornac package uses numpy from its setup.py
This causes an error if the numpy package is not installed before cornac.

Collecting cornac<2,>=1.15.2 (from recommenders==1.1.1)

          import numpy as np
      ModuleNotFoundError: No module named 'numpy'

In which platform does it happen?

I'm having this issue on Mac. I'll update this issue once I test this on Linux.

How do we replicate the issue?

pip install recommenders package.

Expected behavior (i.e. solution)

Install recommenders without any dependency error.

I confirmed I could install recommenders on Linux w/o any issues. The error happens only on non-Linux I guess. I'll close this issue since we don't officially support other OS and the resolution is also quite straightforward, that is simply manually install numpy beforehand.
