According to issue 3150 https://foss.heptapod.net/pypy/pypy/-/issues/3150, this is on purpose, and brings us into feature compatibility with CPython: Python 3.8.6 | packaged by conda-forge | (default, Oct 7 2020, 19:08:05) [GCC 7.5.0] on linux Type "help", "copyright", "credits" or "license" for more information.
import pickle def f(): ... yield 10 ... gen = f() pickle.dumps(gen) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: cannot pickle 'generator' object
I guess we could improve the error message to be more helpful. Do you have a concrete use case for this? Matti. On 12/11/20 1:55 PM, Ioannis Foufoulas wrote:
Hi, While in PyPy was possible to pickle a generator function and resume after unpicking this does not happen with PyPy3:
File "/snap/pypy3/72/lib-python/3/pickle.py", line 942, in save_global (obj, module_name, name)) pickle.PicklingError: Can't pickle <class 'generator'>: it's not found as builtins.generator
Is this a bug or this feature is removed in PyPy3?
