cloudpickle-generators

cloudpickle <https://github.com/cloudpipe/cloudpickle>_ support for generators, including partially consumed generators.

Usage

To use cloudpickle-generators, you must simply call register. After calling register, you may use cloudpickle like normal.

.. code-block:: python

import cloudpickle import cloudpickle_generators

register the generator support

cloudpickle_generators.register()

define a simple generator function that has both intermediate state (the

loop) and arguments

def f(a, b): ... for n in range(a): ... yield b + b[-1] * n

gen = f(4, 'ay')

advance the generator half way though before serializing

next(gen) ay next(gen) ayy

do a serialization round trip

new_gen = cloudpickle.loads(cloudpickle.dumps(gen)) new_gen is gen False

advance the newly created generator instance

next(new_gen) ayyy next(new_gen) ayyyy next(new_gen) Traceback (most recent call last): ... StopIteration

the old instance is unaffected by the new one!

next(gen) ayyy next(gen) ayyyy next(gen) Traceback (most recent call last): ... StopIteration
