Hi Chris, YT has its own routine designed to pickle data objects for saving and reloading. For a given pf, you can do pf.h.save_object(object, name) and the object will be saved to the .yt file associated with the dataset. You can then get it back with object = pf.h.load_object(name). I have used this successfully to save the mast_clump structure from clump finding. Britton On Thu, May 27, 2010 at 9:26 PM, Charles Hansen <chansen@astro.berkeley.edu>wrote:
The find_clumps function is working correctly for me I believe, but the analysis takes a very long time and I'd like to save the master_clump object (from http://yt.enzotools.org/doc/cookbook/recipes.html#cookbook-find-clumps) for further analysis. I've tried pickling master_clump. It dumps correctly, but gives an EOF error (below) on loading. Is there another way to save master_clump?
Thanks, Charles
