我打电话的时候

self.client = ThreadedClient() 

在我的Python程序中,我收到错误

"RuntimeError:主线程不在主循环中"

我已经做了一些谷歌搜索,但我在某种程度上犯了错误...有人可以帮助我吗？

完整错误:

Exception in thread Thread-1:
    Traceback (most recent call last):
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 530, in __bootstrap_inner
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 483, in run
    File "/Users/Wim/Bird Swarm/bird_swarm.py", line 156, in workerGuiThread
    self.root.after(200, self.workerGuiThread)

    File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py", line 1098, in _register
    RuntimeError: main thread is not in main loop

类别:

class ThreadedClient(object):

    def __init__(self):
        self.queue = Queue.Queue( )
        self.gui = GuiPart(self.queue, self.endApplication)
        self.root = self.gui.getRoot()
        self.running = True
        self.GuiThread = threading.Thread(target=self.workerGuiThread) …

我正在尝试在 python 下并行运行多个重复性任务。我对多处理很陌生，但由于所有任务都是独立的，我使用了以下简单的代码：

    import numpy as np
    import sys
    import os
    import glob
    import matplotlib.pyplot as plt
    import concurrent.futures as Cfut

    def analize(simul, N_thread):
        path = os.getcwd()

        print('Analizing topo ...')
        Data = output of some calculations

        print('Writing Data ...')
        np.save('Data', Data)

        print('Data saved')
        print('Printing figures')

        plt.figure()
        plt.plot(Data[0])
        plt.savefig('figure1.pdf)

        plt.clf()
        plt.plot(Data[0])
        plt.savefig('figure1.pdf)

        plt.close('all')
        print('figures saved')
        os.chdir(path

if __name__ == '__main__':
    list_simul = sorted(glob.glob('Layer*'))
    executor = Cfut.ProcessPoolExecutor(5)
   #executor = Cfut.ThreadPoolExecutor(N_jobs)
    futures = [executor.submit(analize, item, 10) for item in list_simul]
    Cfut.wait(futures)

它在 3 …

我编写了一个可以传递图像的简短模块,只需创建一个Tkinter窗口并显示它.我遇到的问题是,即使我实例化并调用在单独的线程中显示图像的方法,主程序也不会继续,直到Tkinter窗口关闭.

这是我的模块:

import Image, ImageTk
import Tkinter


class Viewer(Tkinter.Tk):
    def __init__(self,parent):
        Tkinter.Tk.__init__(self,parent)
        self.parent = parent
        self.initialize()

    def initialize(self):
        self.grid()

    def show(self,img):
        self.to_display = ImageTk.PhotoImage(img)
        self.label_image = Tkinter.Label(self,image=self.to_display)
        self.label_image.grid(column = 0, row = 0, sticky = "NSEW")
        self.mainloop()

它似乎工作正常,除非我从我的测试程序中调用它,如下所示,它似乎不允许我的测试程序继续,即使在另一个线程中启动.

import Image
from viewer import Viewer
import threading

def showimage(im):
    view = Viewer(None)
    view.show(im)

if __name__ == "__main__":
    im = Image.open("gaben.jpg")
    t = threading.Thread(showimage(im))
    t.start()
    print "Program keeps going..."

我想也许我的问题是我应该在模块本身内创建一个新线程,但我只想尝试保持简单,因为我是Python的新手.

无论如何,提前感谢任何帮助.

编辑:为了清楚起见,我只是想制作一个在Tkinter窗口中显示图像的模块,以便我可以在任何时候想要显示图像时使用该模块.我遇到的问题是,只要程序使用此模块,它就无法恢复,直到Tkinter窗口关闭.
