Description:
 def do_not_pickle_attributes(*lazy_properties):
 r"""Decorator to assign non-pickable properties. Used to assign properties which will not be pickled on some class. This decorator creates a series of properties whose values won't be serialized; instead, their values will be reloaded (e.g. from disk) by the :meth:`load` function after deserializing the object. The decorator can be used to avoid the serialization of bulky attributes. Another possible use is for attributes which cannot be pickled at all. In this case the user should construct the attribute himself in :meth:`load`. Parameters \*lazy_properties : strings The names of the attributes that are lazy. Notes ----- The pickling behavior of the dataset is only overridden if the dataset does not have a ``__getstate__`` method implemented. Examples -------- In order to make sure that attributes are not serialized with the dataset, and are lazily reloaded after deserialization by the :meth:`load` in the wrapped class. Use the decorator with the names of the attributes as an argument. """
