运行方法时 Tkinter GUI 冻结(如何添加线程?)

问题描述

很抱歉打扰您，但我想寻求帮助.当我调用 Neural_network 方法时，我的 tkinter 应用程序冻结，因为它中断了主循环.我试图添加线程，但它没有按预期工作.如果有人可以帮助我，我将不胜感激.谢谢！

Sorry for bothering you, but I would like to ask for help. My tkinter application freezes when I'm calling my Neural_network method because it interrupts the main loop. I tried to add threading, but it did not work as intended. If someone could help me out I would really appreciate it. Thank you!

class Toplevel1:
def __init__(self, top=None):
    def neural_network(p1,p2,p3,p4,p5):
        #NEURAL NETWORK STUFF GOING ON HERE
        print(round(prediction.item(0)))
        if round(prediction.item(0)) == 1: self.Label1_6.configure(text='''Malignant''', foreground="red")
        else: self.Label1_6.configure(text='''Benign''', foreground="green")

    def call_neural(p1, p2, p3, p4, p5):
        self.Label1_6.configure(text='''Please wait...''', foreground="black")
        root.after(10000, neural_network(p1, p2, p3, p4, p5))

    def analytics():
        try:
            float(self.Entry1_3.get())
            float(self.Entry1_4.get())
            float(self.Entry1_5.get())
            float(self.Entry1_6.get())
            float(self.Entry1_7.get())
            p1 = (float(self.Entry1_3.get()) - 6.981) / (21.129)
            p2 = (float(self.Entry1_4.get()) - 43.79) / (144.71)
            p3 = (float(self.Entry1_5.get()) - 143.5) / (2357.5)
            p4 = (float(self.Entry1_6.get()) - 0.01938) / (0.32602)
            p5 = (float(self.Entry1_7.get()) - 0) / (0.4268)
            if 0 <= p1 <= 1 and 0 <= p2 <= 1 and 0 <= p3 <= 1 and 0 <= p4 <= 1 and 0 <= p5 <= 1: call_neural(p1, p2, p3, p4, p5)
            else:  self.Label1_6.configure(text='''Error: Out of bounds''')
        except ValueError:
            self.Label1_6.configure(text='''Please fill all fields''')

它解释了各种方法(包括线程方法)，这些方法可用于在执行其他工作时保持 GUI 响应.希望有帮助.

It explains about various methods(including the threading method) which can be used to keep your GUI responsive while doing other work. Hope it helps.
