python - 为什么两个线程没有同时执行？

问题描述

这是我第一次尝试线程，我已经遇到了许多障碍！所以我的代码并行运行两个线程，一个运行一个从服务器接收数据块并将它们放入队列的函数，另一个运行一个从队列中删除数据块并执行计算直到队列为空的函数.

客户端代码为：

import socket
import turtle
import queue
import threading
#import timeit
from tkinter import *

class GUI:
    entries = []
    def __init__(self, master):
        self.master = master
        master.title("Collision Detection")

        self.buff_data = queue.Queue()

        self.t1 = threading.Thread(target = self.recvData)
        self.t2 = threading.Thread(target=self.calculate_threshold)
        self.entries = []

        self.host = '127.0.0.1'
        self.port = 5001
        self.s = socket.socket()
        self.s.connect((self.host, self.port))

        self.create_GUI()

    def create_GUI(self):

        #entries = []

        self.canvas = Canvas(root, width = 150, height = 50)
        self.canvas.grid(row = 4, column = 3)

我运行了一个服务器代码，只发送一个数据块，两个线程都注释了，运行了 start 和 stop 变量，getData()发现传输一个数据块需要 0.0002 秒。然后我运行服务器代码只发送一个数据块并运行 only 的 start 和 stop 变量，calculate_threshold()发现执行计算需要 0.12407 秒。

基于此，我删除了timeit变量并发送了大约 34 个数据块（由于我的帖子正文中的字数限制，我在下面只显示了几个），在发送 10 个数据块后延迟了 0.5 秒，并注意到我在我的控制台中得到这个：

out of loop
okay enter *x 32 times*

为什么控制台打印3个数据块后会有间隙？为什么没有打印“计算”打印语句，为什么它首先执行第一个线程（接收所有数据块）然后执行第二个线程的计算？

我希望两者同时发生。我知道第二个线程需要更多时间，但这就是为什么我在发送数据时添加了延迟，以确保在发送 10 个数据块（每个 0.0002 秒）+ 0.5 秒延迟添加 = 0.502 秒之前，循环第二个线程应该已经执行了 5 次。

如何确保它们是并行的？考虑到我的服务器将是一个硬件，它将以 100Hz 的采样率连续发送数据块，并且发送的数据块没有限制。

解决方案

线程几乎同时运行。使用线程，一旦一个线程启动，下一个线程就会启动。因此，从第 1 次到第 2 次会有轻微的延迟。等等，如果您要进行真正的同时处理，则需要改用您的内核。
