Just as an update to this problem: It does stem from the fact that the data was a boolean object in its dim and distant past: diskouter = pf.h.disk(na.array([16.0, 16.0, 16.0]), na.array([0.0,0.0,1.0]), 7.5, 100e-3/pf['kpc']) diskinner = pf.h.disk(na.array([16.0, 16.0, 16.0]), na.array([0.0,0.0,1.0]), 4.5, 100e-3/pf['kpc']) diskdata = pf.h.boolean([diskouter, "NOT", diskinner]) . . . contours = diskdata.extract_connected_sets("Density", 1, cloud_threshold, maxv+1, log_space=True, cache=True) this_agglomeration = contours[1][0][a] . . . cloud = this_agglomeration.extract_region(agglomeration_peak_assign == p) . . . cPickle.dump(cloud, file, protocol=-1) I also did a very old roll back and confirmed this isn't a new problem; I must have never tried to save an object that was at one point a boolean. Is there any way around this? (Apart from not using the boolean?) Thanks! Elizabeth On Mar 4, 2013, at 10:29 PM, Elizabeth Tasker <tasker@astro1.sci.hokudai.ac.jp> wrote:
Hi Stephen,
That method gives me exactly the same error.
Either I'm doing something silly (quite probable) or perhaps there's been a change to this machinery since the last update?

Hi Elizabeth,
I'm getting a problem with pickle that I've not seen before.
Have you tried save_object / load_object?
