Re: [matplotlib-devel] Test Failure: AttributeError: incompatible shape for a non-contiguous array

[Patrick M. <pat...@gm...>]

Just a follow up for historical sake:

This is a bug in numpy and was introduced in this commit:
https://github.com/numpy/numpy/commit/c48156dfdc408f0a1e59ef54ac490cccbd6b8d73

I've filed a ticket with Numpy and those interested can follow up here:
https://github.com/numpy/numpy/issues/2700
