The message isn't exactly clear. I suspect the problem is a shape mismatch, like colors is 5x3, and igood is just 3 for some reason. Could somebody shine some light on this, please?Ok, I tested matplotlib master against numpy master, and there were no errors. I did get a bunch of new deprecation warnings though such as:
"/nas/home/broot/centos6/lib/python2.7/site-packages/matplotlib-1.5.dev1-py2.7-linux-x86_64.egg/matplotlib/colorbar.py:539: VisibleDeprecationWarning: boolean index did not match indexed array along dimension 0; dimension is 5 but corresponding boolean dimension is 3
colors = np.asarray(colors)[igood]"
