Update pinning

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

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I now get errors in OS X Travis CI:

  /Users/travis/miniconda/envs/test-environment/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: numpy.dtype size changed, may indicate binary incompatibility. Expected 96, got 88

I believe it is coming from matplotlib.

According to https://stackoverflow.com/questions/40845304/runtimewarning-numpy-dtype-size-changed-may-indicate-binary-incompatibility it means that matplotlib is compiled against the wrong numpy version. So I think this was the wrong change.

[ocefpaf]

Can you post the results of conda list?

That version of mpl was built with numpy 1.9.* and you are running with numpy 1.13.1. That should be OK and I cannot reproduce the error on my Linux machine with the same packages:

It seems that you are hitting this on Travis-CI can you point me to the log? Could your config be downgrading to a numpy older than 1.9 there after the conda env is created?

[asmeurer]

https://travis-ci.org/asmeurer/mypython/jobs/262958041

I'm not doing any other conda stuff. I'm not 100% sure where it coming from, but based on the test, I think it is from importing seaborn.

The stackoverflow answer seems to imply that the problem comes from matplotlib being built against an older numpy than what is installed.

[asmeurer]

Also this is OS X, in case you missed that.

[ocefpaf]

The stackoverflow answer seems to imply that the problem comes from matplotlib being built against an older numpy than what is installed.

The stackoverflow is correct but now I can see that you are getting an warning and not an error.

We are OK to do that with an older numpy for build and newer on run, an error should happen only when you do the other way around, see https://stackoverflow.com/questions/17709641/valueerror-numpy-dtype-has-the-wrong-size-try-recompiling/18369312#18369312 and numpy/numpy@170ed4e?diff=split

[asmeurer]

Well I suspect a lot of people are going to be seeing these warnings with these packages built how they are. So maybe matplotlib should also silence them if they really are innocuous.
