Okay, let's back out that changeset. I think it is okay to mandate an instantiated hierarchy if you want to have detailed, output-specific field information.On Mar 15, 2012 10:02 AM, "Eric Hallman" <email@example.com> wrote:_______________________________________________Matt and Stephen,
I can confirm that the seg fault disappears on Mac OS X when updating to h5py-2.0.1, though a simple projection is still giving an out of bounds error on a simple unigrid data set. Not sure why that occurs. But I think Matt is definitely right about h5py:
p = pc.add_projection('Density',0)
