[yt-users] unpickle / load problems

[Elizabeth Tasker]

Hi,

I'm struggling to unpickle / load_object a previously pickled / save_object.

I've done:

pf.h.save_object(allclouds, "clouds_pyfindclouds2_yt")

but when I do:

clouds = pf.h.load_object("clouds_pyfindclouds2_yt")

I get:

AttributeError                            Traceback (most recent call last)

This is all on the same computer.
