Issue with MyProcessPoolExecutor class

[zkiihne]

When I tried to use the Financial Labels notebook(no 5) I was getting the following issue:

object has no attribute '_queue_management_thread_wakeup'

After some poking around the issue is with lines 44 and 46 of utils.py.

The methods that are currently used:

self._queue_management_thread_wakeup.wakeup()
self._start_queue_management_thread()

The its possible the methods that should be used are, but when I did this replacement the threads hang and nothing is returned.

self._executor_manager_thread_wakeup.wakeup()
self._start_executor_manager_thread()

Note: I am running this on windows, with python 3.9 and Cython==0.29.23. The issue could possibly be in the cython version.

any updates on this? I ran into the same problem.

I had the same problem using python 3.10 and solved it when changed to python 3.8.

Without changing any code?

I think the issue was linked to the pool excecutor. It was used in 'process_jobs' function to 'execute parallelized jobs'. So it might be ok to change the executor to 'ThreadPoolExecutor' by changing the para 'use_thread' to True without implementing a wrong impact on the final result.
