[yt-users] Problems with pickle

[Elizabeth Tasker]

Hi,

I'm getting a problem with pickle that I've not seen before.

I have an extracted_region that I'm trying to pickle via:

file = open(('cloud%d_pyfindclouds2.pickle' % p), 'wb')
cPickle.dump(cloud, file, protocol=-1)
file.close()


but I'm getting:


In [16]: cPickle.dump(cloud, file, protocol=-1)
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
/Users/Elizabeth/yt/src/yt-hg/scripts/iyt in <module>()
----> 1 cPickle.dump(cloud, file, protocol=-1)

/Users/Elizabeth/yt/src/yt-hg/yt/data_objects/data_containers.pyc in __reduce__(self)
    403     def __reduce__(self):
    404         args = tuple([self.pf._hash(), self._type_name] +
--> 405                      [getattr(self, n) for n in self._con_args] +
    406                      [self.field_parameters])
    407         return (_reconstruct_object, args)

AttributeError: 'AMRBooleanRegion' object has no attribute 'r'



Does anyone know what might be causing this?
