Пакет python-module-cloudpickle: Информация

cloudpickle makes it possible to serialize Python constructs
not supported by the default pickle module from the Python standard
library. cloudpickle is especially useful for cluster computing where
Python expressions are shipped over the network to execute on remote
hosts, possibly close to the data. Among other things, cloudpickle
supports pickling for lambda expressions, functions and classes defined
interactively in the __main__ module.
