Update python-cloudpickle to 1.6.0

Authored by algent on Sun, Sep 6, 8:08 PM.




  • cloudpickle's pickle.Pickler subclass (currently defined as cloudpickle.cloudpickle_fast.CloudPickler) can and should now be accessed as cloudpickle.Pickler. This is the only officially supported way of accessing it.
  • cloudpickle now supports pickling dict_keys, dict_items and dict_values.

Signed-off-by: Algent Albrahimi <>

Test Plan
  • Update python-spyder-kernels against this version.
  • Run a few python scripts using spyder3.
  • Run this example using cli:
>>> import cloudpickle
>>> squared = lambda x: x ** 2
>>> pickled_lambda = cloudpickle.dumps(squared)
>>> import pickle
>>> new_squared = pickle.loads(pickled_lambda)
>>> new_squared(2)
>>> CONSTANT = 42
>>> def my_function(data: int) -> int:
...     return data + CONSTANT
>>> pickled_function = cloudpickle.dumps(my_function)
>>> depickled_function = pickle.loads(pickled_function)
>>> depickled_function(43)
