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

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

Greetings,

I've banged my head against this problem for 2 days and have given up on
figuring it out on my own…

After updating numpy and matplotlib to the latest versions from github
Saturday morning, I keep getting "AttributeError: incompatible shape for a
non-contiguous array" errors all over the place when plotting. When I run
tests on numpy, everything passes. When I run tests on matplotlib, I get 51
errors, with a vast majority of them (possibly all) being the
non-contiguous array errors. (Sample below)

Any suggestions here? I'm totally stumped.
