I'm running into an error when trying to confirm my flow can be registered

is_serializable(flow, True

gives me some debugging output but the error isn't particularly revealing

subprocess.CalledProcessError: Command 'python /var/folders/vz/kjj4n5wj2bb7q26n0kz4v4jw0000gp/T/tmpr1ux82t1' returned non-zero exit status 1.

Is there a way to get more detail from the debugger?

Looks like that utility doesn’t show any extra output besides the raising the exception so there’s a few things you could do: Overwrite this function to do something with the

subprocess.check_output

call and retrieve stdout through it. Attempt a manual cloudpickle dumps/loads like this:

f = Flow(...)
pickled = cloudpickle.dumps(f)
cloudpickle.loads(pickled)

^ the error might be raised during the serialization

hmm looks like

dumps

and

loads

works fine with the flow is it possible

is_serializable

is a red herring here?
