Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipe) and found some lint.

Here's what I've got...

For recipe:

• Using pinned numpy packages is a deprecated pattern. Consider using the method outlined here.

Hi there, thanks for updating the recipe!
Unfortunately, the builds fail "due to unsatisfiable dependencies: numpy 1.11".
The builds were successful before your update, I'm not sure what causes the problem. There are C-extensions involved that were compiled with cython 0.27.3. Maybe it needs numpy >= 1.12.?
Help would be very appreciated!
