1. The
To run the program, to select a file first, when running with futures. ProcessPoolExecutor () as executor, statements, still pop up multiple folders selection box let me choose the folder
2. But I use with futures. ThreadPoolExecutor (2) the as executor: thread pool, there is no problem (pictured), consult how to use the correct use of with futures. ProcessPoolExecutor () as executor:
