[Numpy-discussion] lots of warnings with python3

[Neal Becker]

I tried running python2 -3 on some code, and found numpy
produces a lot of warnings.

Many like:
python -3 -c 'import numpy'
...
/usr/lib64/python2.7/site-packages/numpy/lib/polynomial.py:928: 
DeprecationWarning: Overriding __eq__ blocks inheritance of __hash__ in 3.x

But also:
/usr/lib64/python2.7/site-packages/numpy/lib/shape_base.py:838: 
DeprecationWarning: classic int division
  n /= max(dim_in,1)
