Example code fails on Windows 10 #648

Description

@stefan-girlich

I am using a pristine notebook and kernel to run the example from the documentation. Execution fails with error messages.

Environment

  • Jupyter Notebook 6.4.5
  • Python 3.8.5
  • ipyparallel 8.0.0

Code

import time
import ipyparallel as ipp

task_durations = [1] * 25
# request a cluster
with ipp.Cluster() as rc:
    # get a view on the cluster
    view = rc.load_balanced_view()
    # submit the tasks
    asyncresult = view.map_async(time.sleep, task_durations)
    # wait interactively for results
    asyncresult.wait_interactive()
    # retrieve actual results
    result = asyncresult.get()
# at this point, the cluster processes have been shutdown

Error
