This seems related to child classes that call super() and appears to be a bug in the pickling/canning process.
import ipyparallel as ipp
class A:
def __init__(self):
self.x = 1
class B(A):
def __init__(self):
pass
class C(A):
def __init__(self):
super().__init__()
# Start the clusters
rc = ipp.Cluster(n=2).start_and_connect_sync()
rc.wait_for_engines(n=2)
dview = rc[:]
dview["A"] = A
dview["B"] = B
dview["C"] = C # <-- RecursionError: maximum recursion depth exceeded
from ipyparallel.
You might try dview.use_cloudpickle()
if you have more complex local objects to push. Otherwise, it's often more robust to just define classes remotely instead of pushign them if you can, e.g. via view.run.
