Concurrent.futures在tkinter中打开新窗口，而不是运行该函数

Question

我正在尝试使用tkinter和parallel.futures在gui中的多个文件上并发运行函数

在GUI之外，此脚本可以正常工作。但是，每当我将其转换为GUI脚本时，该脚本都会打开5个新的gui tkinter窗口（而不是并行运行该函数）（它打开的窗口数等于我允许程序使用的处理器数） 。

我已经彻底检查了代码，只是无法理解为什么它要打开新窗口，而不是仅对文件运行功能。

谁能看到我想念的东西吗？

下面是该代码的节略版本。我删去了大部分代码，只保留了与并行化相关的部分。毫无疑问，此代码中包含我在此示例中未定义的变量。]​​>

    #establish where the files are coming from to operate on
    folder_input = folder_entry_var.get()
    #establish the number of processors to use
    nbproc = int(np_var.get())

    #loop over files to get a list of file to be worked on by concurrent.futures
    files = []
    for file in glob.glob(rf'{folder_input}'+'//*'):
        files.append(file)

    #this function gets passed to concurrent.futures. I have taken out a significant portion of 
    #function itself as I do not believe the problem resides in the function itself.
    def process_file(filepath):

        excel_input = excel_entry_var.get()

    # feed the function to processpool executer to run. At this point, I hear the processors
    # spin up, but all it does is open 5 new tkinter windows (the number of windows is proportionate
    #to the number of processors I give it to run
    if __name__ == '__main__': 
        with ProcessPoolExecutor(max_workers=nbproc) as executor:
            executor.map(process_file, files)

window.mainloop()
