Example code fails on Windows 10

在 Windows 10 上使用所列出的 Python、Jupyter Notebook 和 ipyparallel 版本，从 ipp.Cluster() 开始复现文档示例。检查 error_output.txt 和删除日志失败的消息；示例在清理过程中不出现 WinError 32 失败即表示完成。

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
